Ivan Papusha is a computational scientist and engineer. He is
currently a senior analyst and subject matter expert in Washington,
D.C., with over a decade of research and development experience in
autonomy, air and space systems, and artificial intelligence. His
(continuing) mission: to seek computational craftsmanship—the
virtuous combination of mathematical insight, computing, and
experimentation that expands to elegant solutions of engineering
problems, and delivers rich new ways to think about the world.
He has a PhD from Caltech, and BS and MS degrees from Stanford
University. He is a recipient of the NDSEG Fellowship, a member of IEEE,
and the founder of Subgradient.
