Alex's research interests are in combinatorial scientific computing (CSC), high performance
computing, and bioinformatics.
CSC is an interdisciplinary research area where discrete mathematics and algorithms are applied to
combinatorial problems from Computational Science and Engineering. CSC links scientific computing to
algorithmic computer science.
Current projects include: Graph algorithms on parallel computers; Computing
sparse Hessians via Automatic Differentiation; Real-time matrix computations for simulating
surgery; Algorithms for aligning massive networks via relaxations of quadratic integer programs;
and Algorithms for analyzing, registering, and classifying Flow Cytometry (proteomic) samples.
