Julia Bohannon, PhDAssociate ProfessorAnesthesiologyAssociate ProfessorPathology, Microbiology, and Immunology
Dr. Bohannon completed her PhD at the University of Texas Medical Branch in Galveston, TX, where she began her studies into immune function following severe burn injury. After completing her PhD studies in 2011, she joined the Sherwood Lab at UTMB as a postdoctoral fellow. Shortly thereafter, she assisted Dr. Sherwood in relocating his laboratory to the Anesthesiology department at VUMC in 2012, where she completed her postdoctoral training. She joined Anesthesiology faculty in 2015 and now has her own research program aimed at investigating immunomodulatory therapies for the prevention of infection and sepsis in patients with severe burn and other critical injuries. Utilizing a variety of murine trauma and infection models, as well as ex vivo study of peripheral blood leukocytes obtained from critically ill patients, Julie's studies seek to understand how critical illness causes immune dysfunction and increased susceptibility to infection. The goal of these studies is to develop new approaches to decrease the incidence and severity of infection in critically injured patients.

Past Lab Members
Allison Owen, PhDAssistant ProfessorUniversity of Kentucky
Dr. Owen completed her Ph.D. in December 2017 with a concentration in Physiology at the University of Kentucky in Lexington, KY. Her doctoral work was aimed at investigating underlying mechanisms of long-term skeletal muscle weakness in middle-aged murine sepsis survivors using a refined clinically relevant animal model; this project was supported by an individual F31 NRSA predoctoral fellowship. She transitioned to Dr. Bohannon's lab at VUMC in August 2019 to expand her training in the field of Immunology. She completed her postdoctoral fellowship in 2021 on the role of metabolic flux on antimicrobial function and intracellular signaling pathways by which TLR agonists mediate host resistance to infection, funded by the IMDTP T32 program at VUMC. Dr. Owen returned to University of Kentucky as an Assistant Professor in the Athletic Training and Nutrition Center for Muscle Biology where her current studies are aimed at the role of macrophages as regulators of skeletal muscle regeneration after sepsis.
Naeem Patil, MBBS, PhDManager of Medical WritingVir Biotechnology
Dr. Patil completed his Ph.D. in Pharmacology and Toxicology from the University of Arkansas for Medical Sciences and his clinical training from B.J. Medical College, Pune, India. His doctoral research involved studying sepsis-induced renal mitochondrial dysfunction and acute kidney injury. He completed his postdoctoral fellowship under the mentorship of Dr. Edward Sherwood and and continued as an Early Stage Investigator in the Department of Anesthesiology until 2022. Dr. Patil's Ph.D. and postdoctoral studies were supported by American Heart Association fellowship grants.
