Benjamin Lovitz
I am an NSF postdoc and Zelevinsky fellow at Northeastern University, working with Harm Derksen.
â€‹
I study tensors and quantum information theory. Mathematically, this means applied algebraic geometry, representation theory, and combinatorics. Within these areas, I study tensor decompositions and quantum entanglement theory.
