I'm a physicist at Berea College. I work on three problems: electron hydrodynamics in graphene with Leonid Levitov at MIT, magnetic turbulence diagnostics with Alex Lazarian at UW-Madison, and dark matter dynamics with Mark Vogelsberger at MIT's Kavli Institute. Two first-author papers are at journals (PRL, ApJ), a third is in preparation. All code and data are open.

Before college I built BelSO.org and SavchenkoSolutions.com, platforms now used by students in 40+ countries to prepare for physics competitions. I started them in Belarus at 15 when our training program ended. I still run them from Kentucky.
