About me

I am a postdoc in the Institut de Mathématiques de Toulouse working with Fulvio Gesmundo. Before that, I was a PhD student in Texas A&M University working with JM Landsberg. I am interested in problems arising in complexity theory of matrix multiplication. My research investigates the geometry of tensors, with a focus on studying the rank, border rank, subrank, and border subrank of tensors. The methods I use include representation theory and invariant theory. This is my CV.
