Chemistry, Biochemistry, Geology, and Physics at WU
MESSAGE FROM THE CHAIR
Pat Owens, Chair
Greetings from Sims to all Winthrop chemistry, biochemistry, physics, and geology program friends!
2019 was another tremendous year of student accomplishments with the third largest graduating chemistry class ever, the third highest number (ten) earning ACS professional certification, and a record 12 alums matriculating into doctoral programs—seven into Ph.D. programs and five heading into professional health programs—one to dental and four to medical schools. Notably, 3/12 (25%) of doctoral matriculations are graduates from under-represented groups achieving a central program goal established by department faculty in 2008 during our drive to initiate the Winthrop Eagle STEM program. While overall Winthrop enrollments have been flat for well over a decade, the chemistry program has continued to grow. The past four graduating chemistry classes are all among the five largest in program history. ACS approval of Winthrop’s program in 2003 sparked a surge in growth at the time; ASBMB accreditation of Winthrop’s Biochemistry program in 2013 is providing a significant boost. Our central program focus on student undergraduate research is bringing students interested in these opportunities to campus as is the forensic chemistry track led by Dr. Calloway since its establishment ten years ago. Our faculty are the central reason for these achievements. It has been an honor to serve as Chair these past 25 years with such distinguished professionals who are all so totally centered on students and their professional outcomes! Since the Sims renovation, our faculty have also worked tirelessly to gain over $10 million in external grant funding to make student summer research possible.
Another highlight this year has been the well-deserved appointment of Dr. Takita Sumer as Dean of the College of Arts and Sciences, 15 years after her Winthrop arrival. Dr. Sumter was promoted to Professor of Chemistry in 2014, served for a year as Chair of the Human Nutrition Department and for two years as Vice-Provost for Faculty Affairs. In 2017, Dr. Sumter was elected by scientists across the nation to serve as an ASBMB council member. Takita served as the research mentor for 30 students, many of whom have now completed graduate degrees. This spring, the department was fortunate to hire our top candidate, Dr. Timea Fernandez, into Dr. Sumter’s position; Timea brings a wealth of expertise to our program, and we are looking forward to her arrival.
This spring also saw the retirement of Rachel Law, who arrived at Winthrop in January of 2011 to lead the Winthrop Eagle STEM Scholars program, providing students from low-income families and under-represented groups increased opportunities for graduate work. By 2019, five Eagle STEM cohorts had graduated; 42 (62%) of 68 Eagle STEM alum matriculated into graduate programs. Among these alums, 19 started Ph.D. programs across the nation, ten went to professional health doctoral programs primarily in South Carolina, and 13 began master's degree study across a number of disciplines. The Winthrop Eagle STEM Scholars program was the central objective of Chemistry faculty’s 2008 INBRE II NIH proposal; since its initiation, Winthrop has assumed 100% financial support for its sustainment. The Eagle STEM Scholars program is centered on Winthrop’s core values as stated so well in its mission statement “Winthrop prides itself on being an institution of choice for groups traditionally under-represented on the college campus.”
THIS PAST YEAR HAS BEEN a whirlwind. Teaching, researching, attending conferences, advising, and preparing for tenure has kept me extremely busy. I continue to teach physics with calculus I and II along with modern physics. I appreciated the students that engaged into and worked so hard in these classes. Thanks to the support from the National Science Foundation (NSF) and the Winthrop University Research Council, my research continues around supercapacitors as a new energy storage system due to their high energy density, long-lasting lifetime, and high cycle efficiency. Three undergraduate research students, Darien Nguyen, Isabella Schepisi, and Sean Wechsler, have accompanied me over the past two summers at Brookhaven National Laboratory in Long Island, NY to conduct experiments at the Center of Functional Nanomaterials (CFN). Students were trained on the cleanroom procedures. In addition, they were trained and conducted experiments on the e-beam evaporator, x-ray photoelectron spectroscopy (XPS), field emissions, scanning electron microscopy (SEM), energy dispersive x-ray spectroscopy (EDS), and high resolution transmission electron microscopy (TEM). Darien and Isabella co-authored my paper entitled “Extraordinary cycling stability of Ni3(HITP)2 supercapacitors fabricated by electrophoretic deposition: Cycling at 100,000 cycle,” in the chemical engineering journal, Chem. Eng. J. 2019, 378, 122150-122157. Sean co-authored my published article entitled, “Superior Electrochemical Performance of Pristine Nickel Hexaaminobenzene MOF Supercapacitors Fabricated by Electrophoretic Deposition,” in the ChemSusChem journal, DOI:10.1002/cssc.201902691. Additionally, Darien presented his work at the Southeastern Regional Meeting of the American Chemical Society (SERMACS) conference last year in Augusta, GA and Sean presented his research this year at SERMACS in Savannah, GA. Along with my teaching and research time commitments, I am continuing in my Pre-Engineering Program advisory role with Dr. Gelabert and Dr. Maheswaranathan.
TIMEA JOINED the department August 2019 as an assistant professor, with primary teaching responsibility in biochemistry. She replaced Dr. Takita Sumter (new Dean for ACS). Timea graduated with a major in chemistry from Lorand Eotvos University in Budapest, Hungary in 1997 where she also received her Ph.D. in 2001. Timea then moved to the United States to complete a post-doctoral at the University of Chicago and Rosalind Franklin University of Medicine and Sciences. This past fall, she began incorporating an inquiry-based biochemistry laboratory curriculum into the biochemistry education at Winthrop. Her research project focuses on how antibiotics affect the function of regulatory RNAs as well as using these natural RNA aptamers to aid delivery of antibiotics to resistant bacteria. (Refer to the New Faculty and Staff section for additional information)
Tasker: I'M EXCITED ABOUT my new life as a teacher-scholar at Winthrop. After living in Hungary, Chicago, rural Indiana and suburban Texas the move to Rock Hill turned out to be a very good fit for me and my family. Teaching biochemistry and familiarizing myself with undergraduate research at Winthrop, as well as learning the general flow processes of the department have taken the bulk of my time in the fall. However, I have made some good strides in setting up my research lab. The time has gone by so fast, I cannot believe that the first semester is finished. In the Spring term I’m looking forward to ordering new equipment and supplies for my lab and starting my research projects with three talented Winthrop students. In summary, I am glad that I made the decision to join the Department of Chemistry, Physics, and Geology at Winthrop University in Rock Hill, South Carolina.
DR. GELABERT CONTINUES HER regular teaching of physical chemistry, and in the fall offered a new one-credit hour CHEM420 Special Topics in Materials Chemistry: Hydrothermal Crystal Growth. This course covered some of the variety of ways that water enables the growth of crystals, and importance of this growth to the environment and living systems. Besides synthesis of nanoscale to large industrial-sized crystals, the mineralogy and biology within the anaerobic conditions of hydrothermal ocean vents were studied. Dr. Gelabert continues as the Winthrop institutional director for the multi-institutional materials grant, MADE in SC, administered by SC EPSCoR and now in its 3rd year (out of 5). Dr. Gelabert, Dr. Amir and Dr. Harris participated in the MADE in SC Faculty and Fellows conference, held at the USC Alumni Center in Columbia, South Carolina, on September 20, 2019. Students Sean Wechsler ('20), Thomas Sullivan ('21), and Blake McCloskey ('20), presented posters on their work. The meeting included scientific talks, faculty interactions for establishing collaborations between experimental and computational research, and a panel discussion by the Industrial EPSCoR Advisory Board for student career development.
THIS PAST YEAR HAS BEEN another great one in the classroom and lab! In the classroom, I continue to teach organic, bioorganic and essentials of organic lectures. While the content is the same, the way the material is being presented continues to be updated. Dr. Hurlbert and I worked on incorporating a module into the bioorganic curriculum that allows the students to compare various derivatives of oseltamivir (Tamiflu) based on binding with neuraminidase (Influenza A). This work and the data we have gathered so far has been submitted for publication. In the lab, I had a tremendous group of students the past year and summer: Caylie McGlade (2019), Melody Iacino (2020), Miquela Santoro (2020) Kenny Butler (2023) and Tiffany Dwyer (2020); who synthesized more than 30 derivatives of our sphingosine kinase inhibitor template drug. We are currently getting the final NMRs and plan to publish these results over the Christmas break. There have been a number of students who have worked on this project over the years, and I plan to identify all as coauthors. Personally, my wife and kids are doing great! My oldest is a freshman in high school while the middle is in 6th grade and Thomas is in 3rd (prayers appreciated!). I look forward to hearing from all the graduates on where you are and what you have been up to.
I LOVE my job! I went to college at a very small Lutheran college in Nebraska where I was the only chemistry major in my year. As such, I was able to have very close and meaningful relationships with my professors; however, I recognized that the size of the school was quite restrictive in the opportunities that it afforded. For example, the only research experience that I had during my undergraduate years was a short 9 week program at the University of Arkansas. As I progressed through graduate school (Dartmouth College) and my post-doctoral education (Indiana University), I kept these thoughts in mind. I knew that I wanted to find a place that was small enough that meaningful student/professor relationships could be developed while also affording more research opportunities: I found that Winthrop’s chemistry program provided both of these.
After arriving at Winthrop in 2010, I immediately began building my research program and have continued to expound upon my research over the last two years. My laboratory focuses primarily on understanding how bacteria are able to control metal ion concentrations. You may be wondering what is so remarkable about metals and why it is worth studying. Well, absolutely all living organisms rely on metal ions for survival. If you completely remove metals from the environment, life cannot survive. Conversely, if the concentration of metals inside the cell is allowed to exceed a certain threshold, it becomes very dangerous, and eventually lethal, for any living entity. As scientists, if we can understand the machinery that dangerous organisms use to control metal ion concentrations inside the cell, we may be able to leverage this knowledge to create drugs that target metal ion homeostasis. For example, if we can prevent a cell from recognizing that metal concentrations are building to dangerous levels, the cell will not know that it needs to create detoxification systems and it will die. With my 2018 and 2019 student collaborators, Kiera Alexander, David Brandyburg, Brandy Ellison, Sophie Nguyen Alexandra Perez, Lucia Rodriguez, Hunter Sellers and Katrina Schneider, we have been investigating three main metal systems: copper (in all bacteria), nickel in S. coelicolor, and iron in S. pneuminiae. Our efforts have yielded several published journal articles.
During the last two years at Winthrop, I have continued to be very passionate about adjusting my teaching strategies based on published studies as well as empirical data that I have collected. Nearly all of my classes use the flipped classroom model with active learning strategies incorporated into essentially every class. I believe deeply in creating learning environments that are effective for all students independent of background; this is a very difficult but very worthy goal to strive for and it provides me with daily motivation to think carefully and creatively about the struggles that I’ve observed from each student. I love my job!
THE LAST COUPLE OF YEARS HAVE BEEN AN exciting time in our research group. We were able to secure an ACS-PRF grant for our investigations into the photoredox-promoted addition of organoborates to imines, and we published the preliminary results in Photochemical and Photobiological Sciences. Students working on this project have given several conference presentations at SERMACS and NC Photochem; in fact, Evan Thibodeaux (’21) was named runner up for Best Undergraduate Poster at NC Photochem 2019. This is especially noteworthy considering that there were undergraduate students from several top schools in the area, including UNC Chapel Hill and Davidson College. Evan, along with a couple of new additions to the group, Molly Quetel (’23), and Eric Walters (’23), are continuing to move forward on this project. We are also making headway in our collaboration with Dr. Robin Lammi involving the synthesis and evaluation of polyhydroxy biaryls and teraryls as amyloid-β aggregation inhibitors. Since the aggregation of amyloid-β has been implicated in the development of Alzheimer’s disease, designing molecules which inhibit this process has been an active area of research. After completing the work on the terphenyl- and biphenyl-tetrols, we have begun to investigate how the inclusion of an electron-deficient aromatic ring (pyridine) in these scaffolds affects the inhibitory efficacy. This work has been carried out by a number of capable research students, most recently Brandy Crenshaw (’19), Musu Murray (’19), Benjamin Hernandez (’19), and Kendall Claxton (’22), who have been able to present their work at national and regional ACS meetings. Finally, I was selected to present a poster at the 2018 Gordon Research Conference on Heterocyclic Chemistry describing another area of interest in our group: the syntheses and anti-cancer properties of benzisoxazoloazinium salts. This project involved a collaboration with Dr. Takita Sumter and several former students, two of which have earned their Ph.D.s, and two others are currently pursuing their Ph.D.
IT'S BEEN wonderful the past two years. I have continued to teach a variety of courses taken by chemistry, biology, exercise science, mathematics, computer science, and non-science majors and applied physics minors. These are everyday physics, general physics, general physics laboratory, material science, circuit analysis, and independent study. Due to the high demand for general physics, I taught an additional section as an overload during the fall of 2018 and 2019. My research is based on experimental solid-state physics, materials science, physics education, and professional development of teachers. Obtained a 2017-18 Research Council award for Curriculum Enhancement/Instructional Improvement, and developed supplemental online deep learning activities for general physics using the Blackboard platform. In one of the projects for the independent study course, Peter Nguyen (computer science), investigated the magnetic field produced by DC electric currents. This work resulted in valuable information, knowledge, and new equipment that are useful in teaching physics. A manuscript titled, "An Experiment to verify the current dependence of Ampere’s law for a long current carrying conductor" is accepted for publication in The Physics Teacher. Thanks to the funding from Made in SC EPSCoR grant, we (with Dr. Calloway) conducted a professional development workshop for South Carolina high school teachers at Winthrop University this past summer. This will be continued for the next three summers.

In addition, I served as a consultant for the College Board in the following endeavors: Senior Reviewer for Physics C-Mechanics & Physics C- Electricity and Magnetism, AP Physics Reader 2018 and 2019, and Scoring Guide Development Team member. I was selected to revise the scoring guides and associated teacher and reviewer resources to align with updated AP course frameworks.
I had the privilege and honor to serve as a judge at the SCAS/SCJAS (South Carolina Academy of Sciences)/South Carolina Junior Academy of Sciences) meetings at Presbyterian College (April 14, 2018) and Francis Marion University (March 30, 2019). I presented papers at the Southeastern American Physical Society meetings November 8-10 (2018) at University of Tennessee and November 7-10 (2019) at UNC Wilmington. Attending various conferences allowed me to exchange ideas and has kept me abreast of changes in the world of physics teaching and research. My expertise is also used for adjudicating Ph.D. thesis and reviewing journal manuscripts and physics textbooks for publication.
On a personal note, Shyamala and I enjoyed spending part of our summers in Sri Lanka and visiting South India. Our sons are doing well professionally. Mithu is at Duke University doing a fellowship in Rheumatology & Immunology and Niru is a research engineer at Google Brain.
OUR GROUP HAS shifted focus, somewhat, from carbon sequestration in compost material to decompositional studies, remote sensing, and carbon sequestration in natural environments. We purchased some sensors that will collect the temperature and moisture content of soils every 5 minutes in several successional vegetation plots on campus and transmit the data to us over a wireless network on campus. We are tracking litter decomposition rates in all these plots and researching environmental influences on the carbon loss rates. Blake Campbell and Dakota Shope worked in the lab all summer on this project and recently presented their work at the American Geophysical Union meeting in San Francisco in December. Their work has laid the groundwork for development of further experimental plots off campus in the coming year. I also have two new collaborations with professors on campus beginning in the spring and summer. Kiyoshi Sasaki (biology) and I will begin collecting and analyzing tree cores from the piedmont area in hopes of correlating various climate records. Hye-Sung Kim (political science), Bryan McFadden (geography), and I have started analyzing soil quality and rainfall accumulation as factors of outbreaks of violence in unstable regions around the globe. New lab members, Ashley Allen and Mikayla Burke along with geography research students Michael Kendree and Sara Mulligan will begin tackling this research in the spring.
THIS PAST YEAR IN THE CLASSROOM WAS busy as I taught Subarctic Landscapes, which involves a 9-day trip to Northern Manitoba on the shores of the Hudson Bay with students in August. Twelve-hour days with students for over a week are exhausting, but there is nothing quite like teaching in the field and researching with excited students ready to learn. I was invited to give a lecture on this course development at the University of Oslo this past spring. All this summer research, teaching, mentoring, and personal travel to Kentucky, Virginia, California, and Ohio over the summer made me exhausted before the semester started. Since then, I have traveled to Minnesota for a workshop on sustainability in education, taught our university ACAD course for freshman, have been making plans for an environmental conference in January, preparing to teach a retooled version of Soils and Land Use this spring, and exploring the possibility of a U.S.-based field course for geology and geography students this coming summer.

STUDENTS BEYOND THE WALLS OF WU
Students Learning Beyond the Walls of Winthrop in 2019
This has been another productive year for Winthrop students and professors/mentors traveling to various places around the world. In-depth knowledge obtained has truly enhanced what students learned in the classroom and in the laboratory.
Research at Brookhaven National Lab in Upton, NY
Under the direction of Dr. Fatima Amir, Sean Wechsler and Isabella Schepisi traveled during the Summer of 2019 to Brookhaven National Laboratory (BNL) in Upton, New York. As they performed research, they were required to wear white bunny suits in the cleanroom at the Center of Functional Nanomaterials (CFN) at BNL. In the other photos, Sean and Isabella obtained x-ray photoelectron spectroscopy (XPS) data by using the XPS system at CFN. This was another amazing opportunity for students taking physics courses. For additional information, contact Amir at amirf@Winthrop.edu.
Faculty-led Study Abroad Canadian Trip - Hudson Bay Area
Dr. Werts led a team of eight students to the shores of the Hudson Bay in northern Manitoba in the Subarctic Landscapes class in August of 2019. It is a place most do not get to see as it is only accessible by plane or train. It is both the polar bear and beluga whale capital of the world, due to its fairly unique triple junction of ecological zones, which also makes it an amazing place to study environmental science, geology and ecology.
The team of students expanded and installed a remote sensing network in the tundra environment that is collecting atmospheric and soil data and sending it back to the lab workstations at Winthrop. Students completed vegetation surveys, installed a snow fence, collected geolocation data on research plots and abandoned settlement structures, and calculated the growth rate of trees in the dwarf boreal forest. The team stayed at the Churchill Northern Studies Centre and were able to interact with many other international students and researchers during the trip.
Students had the opportunity to kayak with beluga whales as it is the height of the migration season in August. The whales use the shelter of the river to give birth, but migrate to the open waters of the Bay prior to the sea ice arriving. Students also had the chance to see the northern lights in the evening and had a surprise encounter with a polar bear (while sitting safely in the van with a bear guard). For more information, contact Werts at firstname.lastname@example.org.
Faculty-led Study Abroad Trip to Study Geology in the Bahamas
On December 30, 2019, Dr. Diana Boyer took another class of Geology 345 students to the tropical island, San Salvador, Bahamas. This hands-on course continues to allow students to observe modern carbonate environments and coral reef communities in the Bahamian tropical island. Again students evaluated how physical and biological processes are translated into the rock record. For more information, contact Boyer at email@example.com.

Chemistry Major Starts a Minority STEM Group at Winthrop
Merilyn Shanell Palmer started a STEM group for minorities this past fall. The group is for Minorities who are Astonishingly Driven Scientists (M.A.D. Scientists). They were chartered through Winthrop's Council of Student Leaders (CSL) on September 30, 2019. Based on Merilyn's research, the group was started because minorities are currently underrepresented in the fields of Science, Technology, Engineering, and Mathematics (STEM). Winthrop STEM students will gain exposure to possible careers, internships, research help, professional development, and volunteer opportunities. STEM students can join and benefit from the group without any financial stipulations! The officers are Merilyn Palmer (Founder and President), Carla Wilson (Vice-President), Bryson Samuel (Secretary), and Mrs. Willie Ruth Aiken (Advisor).
On October 25, 2019, the group participated in Oakdale's after school Reading Tent activity. They shared and demonstrated the chemistry involved in making slime. The elementary students enjoyed learning how to make slime!
