Georgia Southern Associate Dean Nandi A. Marshall, DrPH, named president of the American Public Health Association

Nandi A. Marshall, DrPH, professor and associate dean for Georgia Southern University’s Jiann-Ping Hsu College of Public Health, has been named president of the American Public Health Association (APHA), the nation’s oldest and largest organization of public health professionals. Marshall began her presidential term on Nov. 5, following a year as president-elect. She will serve a three-year term on APHA’s executive board, including her current presidential year and a subsequent year as immediate past president. With more than two decades of experience in community-engaged public health, Marshall is widely recognized for her leadership in advancing maternal and child health equity, and for her dedication to preparing the next generation of the public health workforce. She holds a bachelor’s in religious studies from Spelman College, a master’s in public health from East Stroudsburg University and a Doctor of Public Health from Georgia Southern. “Dr. Marshall’s appointment to lead APHA is a tremendous national recognition of her contribution to public health — and a reflection of Georgia Southern’s growing impact on the global public health landscape,” said Avinandan Mukherjee, Ph.D., provost and executive vice president for Academic Affairs. “Her commitment to community partnership, workforce development and health equity exemplifies the values we strive to instill in every graduate of our distinctive public health college.” Marshall’s work has centered on bridging lived experience and scientific research to drive equitable health outcomes. “I’m deeply honored to serve as APHA president,” Marshall said. “Public health calls us to listen to communities, honor their wisdom and work together to build the equitable systems that recognize health as a human right. Equity is not an outcome — it’s a commitment. And I’m grateful to continue this work with purpose, courage and love alongside partners across the country.” Founded in 1872, APHA represents more than 25,000 members nationwide, serving as a convener, catalyst and advocate for equitable health and well-being for all. The association connects practitioners, researchers, educators and policymakers to advance evidence-based public health initiatives.

Georgia Southern University computer science professor awarded NSF grant to advance protein imaging research

Proteins, often called the building blocks of life, play a central role in drug development. When scientists develop new treatments, they must understand how drugs interact with proteins involved in disease mechanisms and with proteins in the human body that influence drug response. Scientists commonly use cryo-electron microscopy (cryo-EM) 3D imaging data to study proteins. While recent advances have enabled higher-resolution images that are easier to analyze, medium-resolution images—which are more difficult to interpret—are still the most common for larger protein complexes. Salim Sazzed, Ph.D., an assistant professor in the computer science department of Georgia Southern University’s Allen E. Paulson College of Engineering and Computing, has been awarded a two-year National Science Foundation grant of about $175,000 to lead a groundbreaking project to develop novel Artificial Intelligence (AI) techniques for determining protein secondary structures from medium-resolution cryo-electron microscopy (cryo-EM) images. Improved modeling from medium-resolution images will help researchers study more proteins efficiently, giving new insights into diseases and potentially guiding the development of new treatments and future drugs. At its core, this research will combine biology and machine learning to study protein structures. The multidisciplinary approach and potential impacts on public health are what most excite Sazzed. “The impetus behind this research is the positive impact on public health and possibly contributing to the biomedical workforce,” he said. “Seeing biology and computer science combine for that kind of impact is incredibly moving.” As the Principal Investigator (PI) for the project, Sazzed will use his expertise in deep learning computer models to focus on a major challenge in structural biology: identifying the two main secondary structures of proteins—the alpha helix and the beta sheet. These structures are critical for a protein’s overall shape and function, but in medium-resolution cryo-EM images they often appear indistinct or lack clear detail, making them particularly difficult to analyze. Sazzed’s research will focus on two main goals. First, he will quantify the variability of alpha helices and beta sheets in medium-resolution images, comparing them to idealized structures. Second, by integrating this structural variability with the image data in a deep learning model, he will aim to generate more precise and accurate representations of protein secondary structures. “When we feed this information into a deep learning model along with the image data, the model should be able to determine protein secondary structures more precisely,” Sazzed elaborated. Sazzed believes students will greatly benefit from this multi-disciplinary approach. In addition to a Ph.D. student, several undergraduate students will be directly engaged in the research. A full-day workshop will also be organized, allowing Georgia Southern students from diverse disciplines to participate. This initiative will build on Georgia Southern’s strong tradition of involving undergraduates in research and will support the University’s recent focus on biomedical and health sciences. “There are many different knowledge areas coming together in this work,” Sazzed said. “It involves computer science, biology, chemistry, and even public health. I look forward to students following the research and exploring these different fields themselves.” Allen E. Paulson College of Engineering & Computing Interim Associate Dean of Research, Masoud Davari, Ph.D., echoes this sentiment and emphasizes its importance to the University’s research profile. “Sazzed’s interdisciplinary research, which bridges the gap between biology and computer science, will foster multidisciplinary research in our college—as it is cutting-edge and potentially groundbreaking in drug development to impact people’s lives nationally and globally,” Davari said. “It’s also well aligned with the college’s strategic research plan—as we make the move to R1 status to be aligned with ‘Soaring to R1,’ which is among the transformational initiatives for the University.” Looking to know more about Georgia Southern University or connect with Salim Sazzed — simply contact Georgia Southern's Director of Communications Jennifer Wise at jwise@georgiasouthern.edu to arrange an interview today.

Georgia Southern electrical and computing engineering faculty member recognized with IEEE Outstanding Engineer Award, granted honor society membership

Masoud Davari, an associate professor in Electrical and Computer Engineering at Georgia Southern University, has been awarded the 2024 IEEE Region 3 Outstanding Engineer Award, making him the first faculty member in the university’s 55-year history to receive this honor. Davari was recognized for his contributions to reinforcement-learning optimal controls for power-electronic converters, his work on integrating power-electronic systems with cyber-attack considerations in modern power grids, and for his leadership in hardware-in-the-loop testing and standards development, including service on the IEEE P2004 standards working group. In addition to the award, Davari was inducted into the IEEE-Eta Kappa Nu (HKN) honor society. His research program at Georgia Southern has earned significant support, including more than $1.17 million in National Science Foundation funding, a 2024 Gulfstream Aerospace Research Fellowship, inclusion in the Stanford/Elsevier Top 2% Scientists list, and selection as a finalist for the 2024 Curtis W. McGraw Research Award.
