Welcome to the website for The Plotkin Research Group

We do research at the interface of biology and physics.

Our current projects involve the molecular-genetic study of the evolution of multicellularity, protein misfolding in neurodegenerative disease, and more recently, viral evolution and molecular therapeutics to SARS-CoV-2. Please see our Research Page for more details.
