Won-Seok Choi, PhD is interested in understanding the mechanisms of neuron death induced in Alzheimer's disease and Parkinson's disease by environmental toxicants. He has investigated signaling pathways triggered by various neurotoxins to define the link to the neuro-degenerative disorders, and to discover therapeutic targets to treat and/or prevent them.

He supports Dr Xia's lab with research, skills training and advice for graduate students.
