Research Interest

I am a Ph.D student at School of Computer Science, Carnegie Mellon University advised by Greg Ganger. My general interests are in designing scalable systems for the cluster management and cloud computing. I am currently involved in the Cluster Scheduling project.

Past Life

In the past I have worked on various things, such as Distributed Systems for Machine Learning and Sketching Algorithms in the earlier days of my graduate school studies.

Even before that, I was working as a financial software engineer for a risk analysis and pricing of credit derivatives including Credit Default Swaps, Credit Linked Notes, and Synthetic CDOs, right after the financial crisis of 2008. This movie summarizes what I learned in first few days of my work.
