Aliaksandr Melnichenka

I'm an undergraduate physicist with two first-author papers and three active research collaborations. With Alex Lazarian at UW-Madison, I built a new single-frequency diagnostic for magnetized turbulence (first-author paper submitted to The Astrophysical Journal). With Leonid Levitov at MIT, I predicted self-oscillatory electron waves in graphene (co-first-author paper under review at Physical Review Letters). With Mark Vogelsberger's group at the MIT Kavli Institute, I model how self-interacting dark matter behaves near supermassive black holes. All code and data are open. Before college I won gold, silver, and bronze at the Belarus National Physics Olympiad and built BelSO.org and SavchenkoSolutions.com, platforms now used by tens of thousands of physics students in 40+ countries. Recent talks include AAS 247 (oral), APS DPP (oral), and an invited 30-minute presentation at The Magnetized Turbulent Universe conference in Mexico.
