Research

I’m an experimental condensed matter physicist, with a focus on two-dimensional materials and their heterostructures. Want to learn more about what that means? Check out some of the articles below:

“What’s in a Name Change? Solid State Physics, Condensed Matter Physics, and Materials Science,” Joseph D. Martin (2015)
“2D materials and van der Waals heterostructures,” K. S. Novoselov , A. Mischenko, A. Carvalho, and A. H. Castro Neto (2016)
“With a Simple Twist, a ‘Magic’ Material Is Now the Big Thing in Physics,” David H. Freedman (2019)
