Mircea Mustaţă


I am a Professor in the Department of Mathematics at University of Michigan. Here is my contact information.

My work is in algebraic geometry. In the past few years my main interest was in various invariants of singularities of algebraic varieties, such as minimal log discrepancies, log canonical thresholds, multiplier ideals, Bernstein-Sato polynomials and F-thresholds. Various points of view and techniques come in the picture when studying these invariants: resolutions of singularities, jet schemes, D-modules or positive characteristic methods. Other interests include birational geometry, asymptotic base loci and invariants of divisors, and toric varieties.

Here are my CV and a list of publications.
