Jan is the lead computational research scientist for Atoms for Humanity, working with co-resident Colton Hicks to develop the scientific capabilities needed to discover and design chemistry for human and environmental health. He holds a PhD in theoretical chemistry from Stanford University, where his doctoral work used high-throughput simulation to uncover complex reaction networks and chemical pathways beyond those initially hypothesized by researchers. At Astera, he plans to apply these approaches to catalyst design, sustainable chemistry, and large-scale reaction discovery. Jan was born in San Juan, Puerto Rico, to a family of teachers.
