The PI

Elsa Bou Ghanem, PhD

Elsa is an Associate Professor in the Department of Microbiology and Immunology at the University at Buffalo (UB). She is originally from Lebanon where she received her bachelor’s degree in medical lab science and master’s degree in immunology at the American University of Beirut. She then moved to the United States to continue her studies. She received her Ph.D. in microbiology and immunology at the University of Kentucky where she performed her thesis work on Listeria monocytogenes developing natural feeding models to more closely mimic human intestinal infections in the laboratory of Dr. Sarah D’Orazio. She then moved up to the lungs to work on Streptococcus pneumoniae infections where she did her postdoctoral training with Dr. John Leong at Tufts University. In 2018 she enthusiastically stared her own lab at UB exploring immunesenescence, inflammation and infection. Her work has been recognized through The Life Science Research Foundation Award, K99/R00 Pathway to Independence Award and Excellence in Leukocyte Biology Early Career Award. Her lab has been funded by grants from several foundations and the National Institute of Health. Her favorite immune cells are neutrophils and she is very dedicated to mentoring the next generation of scientists.

PhD student

Gillian Hodge

Gillian is a PhD student in the lab, primarily focused on the effects of aging on host neutrophil response to Streptococcus pneumoniae infection, by targeting senescent cells to improve neutrophil function. Her overall goal is to eventually work on immunotherapy research for immune diseases. When she is not in the lab, she loves spending time with her two dogs and taking dance lessons.
