Office: Google Sunnyvale

I am a Software Engineer at Google Sunnyvale, a member of Cloud Compute Performance team under S^2Infra Performance umbrella. Previously, I was 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 using performance analysis and machine learning. I was involved in Cluster Scheduling and ATLAS projects.

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.
