The group conducts research in modern biology problems by tapping on strengths in combinatorics, probability and statistics. Our current interests include detection of functional signals in biological sequences and protein networks, algorithms and models for inference of gene duplication history and reconstruction of phylogenetic networks, and discovery of the topological and dynamic principles of transcriptional regulatory networks.

Optimization

The group works mainly on the analysis, design and implementation of algorithms for continuous optimization, possibly with stochastic variables. Topics of interest include conic programming and its applications, interior point methods, nonsmooth Newton methods, augmented Lagrangian methods, iterative methods for large linear systems of equations, feasibility problems, first order methods, stochastic gradient descend and data analysis.
