About Contact Research

Adam Topaz

I am a mathematician working primarily in algebra and arithmetic/algebraic geometry. My research interests mostly revolve around Galois theory, with an emphasis on anabelian geometry and other related topics in arithmetic/algebraic geometry. I am also interested in various other topics, such as algebraic cycles, Hodge theory (Archimedean and p-adic), valuation theory, differential Galois theory, model theory of fields, etc.

I am currently an Assistant Professor in the department of Mathematical and Statistical Sciences at the University of Alberta. I previously held postdoctoral positions at Oxford and Berkeley. I completed my Ph.D. in 2013 at the University of Pennsylvania.
