Tansey Lab Members
Malú G, Tansey, PhD
Professor and Laboratory Director
Director of Center for Translational Research in Neurodegenerative Disease (CTRND)
Malú Gámez Tansey is the Norman Fixel Professor of neuroscience and neurology and Director of the Center for Translational Research in Neurodegenerative Disease at the University of Florida College of Medicine. Prior to arriving at UF, she was a tenured professor of physiology at Emory University School of Medicine in Atlanta and Director of the Center for Neurodysfunction (CNI) and Inflammation and a member of the Center for Neurodegenerative Diseases (CND).
Dr. Tansey obtained her B.S/M.S in Biological Sciences from Stanford University in Palo Alto, CA, and her Ph.D. in Cell Regulation from UT Southwestern Graduate School of Biomedical Sciences in Dallas, TX, where she studied the role of MLCK phosphorylation in regulation of smooth muscle contraction in the laboratory of Dr. James T. Stull in the Department of Physiology. After a short post-doc with Kate Luby-Phelps in the same department, she moved to Washington University Medical School in St. Louis, Missouri to the laboratory of the late John P. Merlie where she elucidated the signaling mechanisms required for ARIA/Heregulin-induced acetylcholine receptor epsilon gene expression at the neuromuscular junction before settling in the laboratory of Eugene M. Johnson Jr. in 1996. She and her colleagues in the laboratory of Jeff Milbrandt identified new members of the GDNF Family of Ligands (GFLs: Neurturin, Persephin, and Artemin) and their paired GFR binding co-receptors (GFRalpha2 and 3) and demonstrated their potent bioactivities on multiple neuronal populations. Their work was the first demonstration that ligand-induced recruitment of a neurotrophic receptor (Ret) to lipid rafts for interaction with c-Src was functionally required for GFL-induced neuronal survival and differentiation.
Prior to setting up her academic research lab in 2002, she was head of the Chemical Genetics group at Xencor, a private biotechnology company in Monrovia, California whose mission is to create superior biotherapeutics through protein engineering technology. She and her colleagues engineered soluble TNF-selective biologic inhibitors with a novel dominant negative mechanism of action which her lab has used as powerful tools to investigate the role of TNF signaling in neurodegenerative and neuropsychiatric diseases using in vitro and in vivo models. The translational research goal of these studies is to target soluble TNF with the brain-permeant lead clinical candidate XPro1595 in clinical trials for CNS diseases characterized by chronic central or peripheral inflammation. The general interests of her laboratory include investigating the role and regulation of neuroinflammatory and immune system responses in modulating the gene-environment interactions that determine risk for development and progression of neurodegenerative and neuropsychiatric disease.
In her spare time, Malú enjoys cooking, running, sailing, scuba-diving and spending time at home with her family.
Mary Herrick, Graduate Student
Mary Herrick is a member of the Neuroscience Graduate Program and joined the Tansey lab in 2016. During her undergraduate career, she worked in a number of labs at Auburn, Vanderbilt and the University of Cambridge. She received her B.S. in Microbial, Cellular, and Molecular Biology from Auburn University in 2013, and then spent two years at Vanderbilt University working as a research assistant. Her research focused on the role of microglia in hypothalamic inflammation due to diet-induced obesity, which spurred her interest in neuroinflammation in neurodegenerative diseases. Currently, she is Emory’s GSGA Executive Vice President and the GIN Treasurer. When she’s not in lab she enjoys working out, traveling, and cheering on her Auburn Tigers and New York Yankees.
Valerie Joers, Post-doctoral Fellow
