Our research primarily focuses on developing novel statistical and combinatorial algorithms to analyse massive genomic datasets and provide biological insights. A defining aspect of our computational genomics work is the use of parametric complexity analysis (Nagarajan & Pop, JCB 2009) and exact algorithms (Gao et al., RECOMB, JCB 2011; Wilm et al., NAR 2012) to design bioinformatics tools with provable performance guarantees. We primarily focus on addressing questions in three areas a) Sequence Analysis & Assembly b) Metagenomic Analysis and c) Integrative Genomics.
