My research interests lie broadly in the fields of Virtualization, Cloud Computing, Systems Security and Software Engineering (SE) in general, with a recent focus on Machine Learning and Artifical Intelligence (AI) within the SE context.
I started my research career exploring systems optimization. This included developing adaptive data prefetching schemes for parallel and distributed applicatons during my Master's, followed by leveraging heterogenous computing for cloud acceleration in the early part of my Ph.D.
Thereafter, I transitioned to cloud monitoring and analytics, focusing on developing non-intrusive approaches to achieve visibility into virtual machines and containers.
Systems monitoring naturally transformed into systems security research, including vulnerability analysis of container images, exploration into secure container runtimes, as well as secure container sidecars.
Continuing within the security theme, my recent focus has been on AI-assisted software vulnerability detection. Specifically, I work towards reliable and trustworthy AI modeling of code, incorporating SE techniques into AI model learning to improve the models' signal awareness (i.e. focusing on the relevant source code features).
I graduated from University of Toronto in 2016 with a Doctorate in Computer Science (advisor: Eyal de Lara, IBM mentor: Canturk Isci). I have a Master's (advisor: Sanjeev K. Aggarwal) and Bachelor's degree from Indian Institute of Technology, Kanpur (2010).
In the past, I have spent my summers at Microsoft Research Redmond in 2008 (Networking Research Group; mentor: Parveen Patel), Microsoft Research India in 2011 (Mobility, Networks and Systems Group; mentor: Vishnu Navda), and IBM Research T.J. Watson NY in 2012 and 2013 (Virtualization Runtime & Tools Group; mentor: Canturk Isci).
