Dr. Kristal Tucker earned a bachelor’s degree in Biology from the University of Tennessee in 1994. In 2010 she received a Ph.D. in Neuroscience from Florida State University, where her research focused on the effects of diet-induced obesity on the neurobiology of the brain. During the time between her undergraduate and graduate degrees, Dr. Tucker worked as a research scientist at Auburn University, Florida State University, and the pharmaceutical Schering-Plough, studying ion channels, the proteins responsible for the electrical signals in the brain and heart. Before joining the faculty at Penn State Greater Allegheny, she was a Research Instructor at the University of Pittsburgh, investigating the electrical and metabolic properties of the neurons that die during Parkinson’s disease, the dopamine neurons of the substantia nigra. Now that she is here at Penn State Greater Allegheny, she is excited to be part of the Biobehavioral Health program helping undergraduates reach their

career goals. As well as teaching biology and neurobiology courses, she is thrilled to open her lab to undergraduate research in neurobiology.


Area(s) of Expertise:
Neurobiology, Parkinson's Disease, Olfaction, Ion Channels


Research Interests

Dr. Tucker's research focuses on the brain cells that die as a result of Parkinson's Disease, the dopamine neurons of the substantia nigra.  The death of these cells cause the cardinal symptoms of the disease, difficulty moving, resting tremor, rigidity and postural instability.  Dr. Tucker studies the effects of heavy metals and oxidative stress on dopamine cells with her undergraduate students in the CURE Lab at Penn State Greater Allegheny in collaboration with Dr. John Peles and Dr. Megan Nagel.
