In 2020, the City of Valdosta was awarded a Georgia Smart Communities Challenge 2020 grant for their proposal “Developing, Implementing, and Evaluating a Traffic Monitoring and Communication System for the City of Valdosta and Its Communities to Improve Safety, Connectivity, and Efficiency”. Dr. Hojjatie, Professor of Engineering Studies and Coordinator of the VSU Engineering Studies program, has been serving as Research Partner as part of the collaborative team led by the city. With the City of Valdosta and Project Manager Patrick Collins (City Engineer and Director) leading the efforts, other project partners include Valdosta State University, Lowndes County, Temple, Inc., Applied Information, Inc., and Research Partner Dr. Baabak Ashuri with Georgia Tech.
According to the proposal, the focus of the project is to “create new capabilities for the City of Valdosta’s Traffic Management Center”. Through this project, the City of Valdosta is working toward the vision of a smart traffic management system in which the 128 major traffic signals found within the city communicate with one another, resulting in improvements in traffic flow, increased road safety, and a reduction in the number of traffic accidents.

Meet Dr. Hojjatie:
Dr. Hojjatie received his Ph.D. in Mechanical Engineering from the University of Florida and also holds a PE licensure (Professional Engineer). He is the coordinator of the VSU Engineering Studies program, highlighting the Regents’ Engineering Pathway Program (REPP) connection to Georgia Tech. His research interests include computer aided design/engineering (CAD/CAE), computational/experimental mechanics and heat transfer analyses related to dental materials and other biomaterials, pulp and paper manufacturing, and paper physics.
Dr. Billy Quarles, Assistant Professor of Astronomy and Physics, recently co-authored a paper titled “Exomoons in Systems with a Strong Perturber: Applications to α Cen AB” that was published in The Astronomical Journal in July 2021. Dr. Quarles and his associates propose that if moons orbiting a planet exist within Alpha Centauri (believed to be the nearest star system to our sun), then they should be detectable utilizing current technology.
According to Dr. Quarles, the Alpha Centauri system is used as a prototype because it is the closest stellar binary to us and is suspected to harbor some exoplanets, though that has yet to be confirmed. He and his colleagues propose that if exomoons (exosolar moons) exist within the Alpha Centauri system or any other stellar binary, they should be detectable using the current technological technique of transit timing variations, or TTVs. TTVs allow for the accurate transit timing information from modern observations and from there, researchers can determine whether a transit is occurring sooner or later than it should.
Dr. Billy Quarles is an Assistant Professor of Astronomy and Physics in the PAGET Department at Valdosta State University. He received his Ph.D. from the University of Texas at Arlington.
“My research involves the observation and theoretical study of planets with multiple suns. Like Tatooine, such exoplanets orbit a pair of stars and these exotic worlds are no longer science fiction or theoretical curiosities. The Kepler Space Telescope has discovered around a dozen binary stars that host at least one circumbinary planet (CBP), where the stellar binary orbit lies completely within the planetary orbit. Additionally, I am interested in planets that orbit only one star out of the stellar binary. The nearest star to the Solar System is Proxima Centauri, which orbits the binary star system Alpha Centauri AB. My work explores how an Earth-like planet would orbit either star in the binary and the consequences for life as we know such a world.”
“I became interested in science from an early age and grew to appreciate astronomy greatly throughout my childhood. My interest in planets evolved from watching science fiction dramas like Star Trek: TNG and Contact due to their exploratory nature of alien worlds. As a graduate student, I discovered that it was possible to have a career exploring alien worlds, no starship required. From there, I became interested in the dynamics of planetary orbits and the possible origins of planets.”
The College of Science and Mathematics is proud to share the accomplishments of Chemistry student Danielle McKay. In December 2020, Danielle was awarded the American Chemical Society’s Student Leadership Award and was subsequently invited to attend their nine-month Leadership Institute Experience.

Danielle anticipates graduating in December 2021 and during her time at VSU, she has served as president of SMACS, is a member of the National Council of Negro Women, helps manage the Chemistry Department’s stockroom, and has served as a lead student peer mentor with the GUIDES peer mentoring program. After graduation, she hopes to pursue a career as a cosmetic formulation chemist.
PAGET’s Professor of Geography Dr. Jia Lu and her students, Anthony Oliveira and Marcus Ben Singletary, recently co-authored a paper titled “Pharmacy Disparities in Rural Georgia” that was just accepted by the peer-reviewed Journal of Rural and Community Development. (To find out more about the Journal of Rural and Community Development, click here: https://journals.brandonu.ca/jrcd/about).
The study analyzed geographical patterns of spatial equity of pharmacy using GIS technology. Results suggest that many pharmacy deserts exist in Georgia, and large urban areas have more access to pharmacies than rural areas and small cities. Rural areas could experience the adverse effects of pharmacy deserts more than non-rural areas. There is a clear, positive relationship between rural counties and a lower number of pharmacies. Relationships between pharmacy locations and various racial and demographic variables were also explored. Policy suggestions were proposed to increase access in pharmacy deserts.

Four current and recent VSU students are involved in an experiential learning and research project through the National Science Foundation’s I-Corps™ program. The NSF describes their program as follows:
“The National Science Foundation’s Innovation Corps (I-Corps™) program uses experiential education to help researchers gain valuable insight into entrepreneurship, starting a business or industry requirements and challenges. I-Corps enables the transformation of invention to impact. The curriculum integrates scientific inquiry and industrial discovery in an inclusive, data-driven culture driven by rigor, relevance, and evidence. Through I-Corps training, researchers can reduce the time to translate a promising idea from the laboratory to the marketplace. NSF is developing and nurturing a national innovation network to guide scientific research toward the development of solutions to benefit society.”
Two of the students have co-authored a paper that is submitted to a peer reviewed international journal. It describes the new compound that was tested by the National Cancer Institute. While the NCI tested it against nine types of cancer, the student group is focusing on lung cancer, which has an 80% mortality rate.
Former VSU student, Teighlor Livingston, says,“The NSF’s I-CORPS program allows students to move out of the lab and into the industry. I enjoy the program because it provides the opportunity to discover and face potential challenges in innovation development, while advancing interpersonal skills.”

Dr. Adam Safer’s summer herpetology class is featured in the most recent bulletin published by Georgia Department of Natural Resources. Back in June, they had the opportunity to help biologists check turtle traps located on the Alapaha River and the results are in – they logged four different types of turtles, with the Suwannee alligator snapping turtle as the targeted species, the largest of which weighed nearly 40 pounds!
Students were able to assist in obtaining data on these snappers including sex determination, weighing, measuring upper and lower shell lengths, and marking them with a transponder. This information will be integral in helping assess the species’ status.
Current Biology graduate student Kenyanna Taylor was recently awarded second place in the Graduate Oral Presentation Competition at the American Peanut Research and Education Society Conference held on July 11-14.
