Starting May 1st 2014 I have joined the Bioinformatics Group at the New York Genome Center (NYGC). My new home page can be found here.
Short Bio

I am currently a Computational Science Analyst I at the Simons Center for Quantitative Biology (SCQB) of Cold Spring Harbor Laboratory (CSHL) where I am working with Professor Michael Schatz to develop novel algorithms and computational systems to analyze DNA sequences, concentrating on the assembly and alignment of next generation sequencing reads. Applications include analysis of genetic variations in human genome to identify the genetic causes of various human diseases including autism, cancer, and other psychiatric conditions. Before this position, I was appointed as a Research Scientist at the NYU Bioinformatics Group of Courant Institute of Mathematical Sciences (CIMS) where, together with Professor Bud Mishra, I developed novel sequence assembly and base-calling methods for next generation sequencing data. I received a Ph.D. in Computer Science from New York University (NYU) in 2011 and from University of Catania (UniCT) in 2008 respectively. I have been awarded an IBM PhD Fellowship for the 2010-2011 academic year.

Research Interests

Thanks to the enormous advances in DNA sequencing technology there is now the potential to perform analyses that can be directly applied to many different areas in Computational Biology such as, genome-wide association studies, detecting new polymorphisms, finding rare and de novo mutations. However the availability and performance of the computational tools required to analyze these data continue to lag far behind the improvements in technology. To address this issue, my research has focused on designing an developing new techniques and algorithms for different Computational Genomics problems. In particular my main areas of research are: Variant Calling, Genome assembly, Base-Calling, and Assembly Validation for Next-Generation sequencing technology. I previously worked in: Protein Structure Prediction, Multi-objective Optimization, Evolutionary Computation and Multi-Agent Systems.
