Recent NewsI successfully defended my thesis on Large Scale Code Clone Detection and graduated from UC Irvine to join Tools for Software Engineering group at Microsoft. I was honoured to have Prof. Cristina Lopes (chair), Prof. Andre van der Hoek and Prof. James Jones in my dissertation committee.I am the Program Co-chair for IWSC 2017. It is an excellent venue to show case your research related to software cloning. Please consider submitting. Brief BioI am currently a Sofware Engineer in the Tools for Software Engineering (TSE) group at Microsoft. Before joining TSE, I graduated with a PhD in Informatics from the School of Information and Computer Science, University of California Irvine. My advisor was Prof. Cristina Lopes, Department of Informatics, University of California Irvine in 2016. I was also awarded a Master of Science in Information and Computer Science at University of California, Irvine in 2012. My disseration topic was Enhancing Component Identification Using Machine Learning.Before joining University of California Irvine, I worked at Tata Research Development and Design Centre, India. I have had the privilege of doing internships from industrial research labs to product groups to startups.I spent my summer'11 at SRCH2, a startup specialized in improving user experiences in the domain of search; summer'12 in a product group (Interactive Entertainment Business) at Microsoft Silicon Valley; summer'13 in Human Interactions in Programming and Empirical Software Engineering groups at Microsoft Research in Redmond. |
Research InterestsMy primary research interest has been in the area of Software Engineering with an emphasis on Software Evolution. I am interested in developing theoretical and practical techniques and tools for helping people tounderstand, and modify software systems. My research activities to achieve this goal so far span the spectrum from quantitative measures for software properties, to analysis of software changes, to code modularization, to architecture recovery. In order to ultimately overcome the essential difficulties, it has been recognized that both the processes and products of software development should be formalized and automated. I believe that AI/ML techniques can play an important role in this effort since the field of software engineering turns out to be one such fertile domain where many software development and maintenance tasks could be formulated as learning problems and ML techniques could be used to obtain solutions.
