Research Cooperative Membership Approved

The College of Science and Mathematics and the Institute for Coastal Plain Science recently submitted a successful application for Georgia Southern membership in the Piedmont-South Atlantic Coast Cooperative Ecosystem Studies Unit (PSAC-CESU). The PSAC-CESU is one of 17 cooperative research units across the United States that provides research, technical assistance and education to resource and environmental managers at such federal agency partners as the U.S. Geological Survey, National Parks Service, U.S. Forest Service, U.S. Army Corps of Engineers and National Oceanic and Atmospheric Administration. Though they are called "ecosystem studies" units, work within this cooperative ranges from anthropology to zoology. As a member, University faculty and students will be provided with unique opportunities to conduct research on federal and state projects, and will have significantly enhanced opportunities for research funding. Georgia Southern is one of only four institutions in Georgia approved for membership in the PSAC-CESU.

Bo Ginn National Fish Hatchery

The College of Science and Mathematics signed a memorandum of understanding with the U.S. Fish and Wildlife Service to use and conduct research at the Bo Ginn National Fish Hatchery. Located near Millen GA, the 127-acre hatchery is adjacent to Magnolia Springs State Park, and consists of 25 earthen fish production ponds and four artificial stream raceways. Use of this site will allow Georgia Southern faculty and students to conduct large-scale, replicated studies in a variety of aquatic habitats and on a wide range of topics. Therefore, this arrangement will greatly enhance research and funding potential for our faculty and students.

Biology Professor Featured on Cover of Systematic & Applied Acarology

Dr. Lance Durden’s and collaborator’s research on ticks and quail was also featured on the cover of Systematic & Applied Acarology.

Biology Grad Student Receives Funding

Biology Graduate Student Jade Boykin received The Society for Integrative & Comparative Biology (SICB) Grants-in-Aid of Research (GIAR) Award. Jade will be able to use her $1,000 grant towards research expenses related to her project, "The Biochemical and Genetic Effects of Sleep Deprivation in Zebrafish (Danio rerio)".

Sleep is a universal phenomenon in vertebrates (animals and humans!) and lack of sleep has been linked with various abnormal behaviors and serious negative health effects. As continual stress has also been linked to adverse health implications, it is likely that negative health effects associated with sleep deprivation is a direct result of elevated stress. Using zebrafish as our model system, the objective of our study is to determine if sleep deprivation causes increased stress, exhibited by changes in levels of stress hormones and behavioral changes. Additionally, we will investigate changes in the production of genes (DNA) regulating the production of stress hormones and mechanisms of circadian rhythm.

Special Thank You to Dr. Daniel Hagan and Miriam Hagan

The Department of Biology is very grateful to Dr. Daniel Hagan and Miriam Hagan. Dr. Hagan is an Emeritus Professor in Biology and a former Alumnus of the Year. The Hagans made a significant contribution towards endowing a foundation account to support our Distinguished Biology Alumnus of the Year program, the longest-standing alumni-recognition program at Georgia Southern. Their gift will help make sure this program is supported in future years.

Dr. Anke Hildebrandt Talk

Thursday, Feb. 11th 2016 at 4-5pm

Herty Building, Statesboro, GA, United States (Room 2112)

Statesboro, GA

Dr. Anke Hildebrandt is Junior Professor for Ecological Modelling at the Institute of Geoscience at Friedrich-Schiller University and Max Planck Institute for Biogeochemistry in Jena, Germany. As Group Leader for the Ecohydrology working group, her current research integrates modeling and field methods to investigate feedbacks between water and vegetation from the top of the canopy to the bottom of the rooting zone.

Dr. Hildebrandt is visiting Georgia Southern University as a collaborator on a recently funded National Science Foundation grant seeking to determine how hydro-meteorological processes in forests are altered with urbanization. Although much is known about how urbanization affects routing of water at and below the surface, little work has quantitatively characterized how urban alterations to forest canopy structure influences the amount of water available to the surface and subsurface. Working with Georgia Southern professors, Drs. Van Stan and Underwood, and other international scholars (Jan Friesen – Helmholtz Centre for Environmental Research, Jean-Francois Cote – Natural Resources Canada) on this project, Dr. Hildebrandt will assist in developing models to allow water resource managers to better predict precipitation inputs in forested urban watersheds.

During her February visit she will present current work on grasslands at Friedrich-Schiller University and Max Planck Institute for Biogeochemistry. Title and Abstract

Researchers Rescue Sea Turtle

An endangered Kemp’s Ridley sea turtle named Catherine holds a special place in the hearts of researchers with the Georgia Southern University Sea Turtle Program at St. Catherines Island. Researchers rescued the four-year-old turtle that had swallowed a fishing hook this summer and assisted in her recovery and recent release back into her natural habitat. For nearly 30 years, the program has been making strides in sea turtle conservation efforts along the Georgia Coast.

Undergraduate students from around the region will present sessions and participate in a problem solving contest. For those who do not participate in the problem solving contest, two of our graduate students, Moriah Gibson and Matt Just, will discuss various aspects of being a graduate student.

Eagle Battalion to Build New $9.5 Million Building

As part of the state’s $21 billion state budget, $9.5 million was approved to construct a new Georgia Southern University Military Science Building.

Georgia Governor Nathan Deal visited the Georgia Southern campus on April 28, 2014 to sign the budget bill at the foot of the Marvin Pittman Administration Building. The funding will addresses a great need for the Eagle Battalion ROTC Program. Construction is slated to begin in January 2016. The new facility will be located on the corner of Old Register Road and Forest Drive, adjacent to Highway 301.

The building, encompassing 32,000 square feet, will replace a 10,000 square-foot temporary facility that the Battalion has occupied for nearly a decade.

Dr. Maxim Durach's Nanotechnology Computational Group

Two major results have been obtained by the Nanotechnology Group, led by Dr. Maxim Durach. In a paper by Applied Physical Sciences graduate students David Keene and Matthew LePain and Dr. Durach it is shown that 30-nm thick monolayer metal-dielectric metasurfaces can drastically modify the properties of radiation passing through them and entirely change the spin state of the constituent photons. In their manuscript (arXiv:1512.08139, “Ultimately Thin Metasurface Wave Plates”), submitted for peer-review, they show that the extreme anisotropy of the proposed metasurfaces sets the ultimate lower limit for the thickness of optical waveplates. This result can be applied to the design of ultrathin wave plates, Pancharatnam-Berry phase optical elements and plasmon-carrying optical torque wrench devices. Read more...

Dr. Xiaojun Wang Research in Phosphors

Dr. Xiaojun Wang, Professor of Physics, performed very productive research when he took an educational leave last semester. He attended the 3rd International Workshop on Persistent and Photostimulable Phosphors (Arlington, TX, USA, Nov. 9-13, 2015) and gave an invited talk titled: "Photo-stimulated EPR Studies on the Trapping/Detrapping Processes of Persistent Phosphorescence." He published several papers, including one appearing in the top rated journal, Nanoscale (Nanoscale 7, 14752-9 (2015). DOI: 10.1039/C5NR04125B), and one featured on the front cover of Dalton Transactions (Dalton Trans 45, 1364-72 (2016, front cover). The latter was co-authored with a visiting professor from China, Dr. Yuxue Liu. He also made two publications, one in J Raman Spectroscopy and another in Optics letters (Opt Lett 40, 1434-37 (2015)) with a visiting professor, Dr. Chenglin Sun. After many years’ efforts, he published an undergraduate research article (with Dr. Li Ma Professor of Physics, two physics majors (David Keene and Joshua Klingel), and a visiting scholar (Dr. Aijun Li)) in Am J Physics (Am J Phys 84, 32-37 (2016)), the most influential journal in undergraduate physics research.

In addition, using his optical techniques to precisely measure the thickness of the unique antifogging thin-films prepared by Dr. Ming and his postdoc, Dr. Jie Zhao, in the Georgia Southern Department of Chemistry, he also co-authored a paper published in RSC Advances (RSC Advances 5, 102560-102566 (2015) DOI: 10.1039/C5RA21399A). Dr. Wang continues to serve as an editor at Materials Research Bulletin (Elsevier, and Light: Science & Applications (NPG,

Dr. Monique Aller Presents Interstellar Matter Research at the International Astronomical Union

Dr. Monique Aller has been actively pursuing her research program on “CONNECTING THE INTERSTELLAR GAS AND DUST PROPERTIES OF DISTANT GALAXIES” which is in year 2 of a 3-year NASA-ADAP grant funding this research. As part of this research, Dr. Aller attended both the International Astronomical Union (IAU) General Assembly meeting last August in Honolulu, Hawaii and the American Astronomical Society (AAS) meeting in Kissimmee, Florida in early January to present her research on this project.

Physics Team Drs. James & Sarah Higdon Study Star Formation in Galaxies

A study by James & Sarah Higdon investigating the peculiar star formation law of the Cartwheel ring galaxy was accepted for publication by the Astrophysics Journal Letters. Data obtained with the Atacama Large Millimeter Array (ALMA) telescope, located high in the Chilean Andes, played a crucial role in this research. They have been invited to present these (and other) results at a special ALMA workshop organized by the National Radio Astronomy Observatory (NRAO) in Charlottesville, Va. in April.

HST color images of ring galaxies AM 0644-741 and Arp 147 currently being observed with ALMA. The blue rings indicate high rates of star formation, triggered by the collision with a companion galaxy. They are, respectively, 300 and 430-million light years distant.

Also, the team was recently awarded additional observing time with the ALMA telescope to study cold molecular gas in two additional ring galaxies (AM0644-741 and Arp 147) to gain further insight into star formation in extreme environments.

The Higdon’s and their collaborators at Cornell University were awarded time with the Karl Jansky Very Large Array (JVLA), the premiere radio telescope in the world, to probe star formation in galaxies in the very distant universe, corresponding to an epoch only 3.6-billion years after the Big Bang.

In addition, they were also successful in being awarded observing time with NASA’s SOFIA (Stratospheric Observatory For Infrared Astronomy), an infrared telescope mounted in a converted Boeing 747. Our group will be studying star formation in the core of the “nearby” (35.5-million light years) spiral galaxy M 83. Both the JVLA & SOFIA observing proposals were written while visiting Cornell University over the Summer 2015.

Microwave Ovens Are Not Just Kitchen Appliances

While for most of us microwave ovens are nothing but kitchen appliances used to “nuke” our breakfast, for Dr. Amarie’s students in Studio Physics 2 (Electricity, Magnetism and Optics) they are laboratory instruments. For them, the oven is a microwave resonant cavity capable of sustaining stationary electromagnetic waves (schematics, Figure A) in the microwave range characterized by nodes (cold spots) and anti-nodes (hot spots) similar to a vibrating guitar string when we play a note. But how to make the invisible waves visible, is the question? Well, we chose a very delicious approach: a platform covered first with a pattern of marshmallows (Figure B), then with Hershey’s chocolate bars “revealed” the hot spots as they melted (Figure B - inserts) and measurements were possible. To our surprise, given such a crude method, we determined a wavelength of 12.5 cm (5 inches), give or take a marshmallow, which comes within about 2% of the theoretical value of a 2.45 GHz microwave oven. As you can imagine the demo was a blast, we had to take advantage of the situation and since graham crackers started to show up out of the well-prepared students’ backpacks, the s’mores time was on! See? Physics is so sweet! Read more...

Faculty published in Clinical Microbiology and Infection

Dr. Natalja Rudenko, a visiting scholar in the ICPS, in collaboration with Dr. Jim Oliver, has produced an important paper that was accepted for publication by Clinical Microbiology and Infection (impact factor 5.197). This is milestone work, as it changes significantly the point of view on Lyme disease in the southeastern United States and on the present antibiotic treatments of patients.

The accepted manuscript presents the results of few recent years of their hard work at Georgia Southern in the Institute for Coastal Plain Science (ICPS). This is their first manuscript of clinical character (instead of ecological) that was produced in collaboration with Georgia Southern and there is much more in line to be completed.
