Short Bio

I am a Senior Bioinformatics Scientist at the New York Genome Center (NYGC). My research interest is in developing novel algorithms and computational systems to analyze DNA sequences, concentrating on the assembly and alignment of next generation sequencing reads. Before joining the NYGC, I was a Computational Science Analyst at the Simons Center for Quantitative Biology (SCQB) of Cold Spring Harbor Laboratory (CSHL) where I worked with Professor Michael Schatz on micro-assembly algorithms for indels detection. Before that, I was a Research Scientist at the NYU Bioinformatics Group of Courant Institute of Mathematical Sciences (CIMS) where, together with Professor Bud Mishra, I worked on several problems at the core of computational genomics, such as, DNA sequence assembly, base calling, and metrics for assembly quality evaluation. I earned my Ph.D. in Computer Science from New York University in 2011. In 2010 I received the "IBM Ph.D. Fellowship award" for my innovative research in Computational Genomics.
