I am a Software Engineer at Google Sunnyvale, a member of Google Compute Engine - VMX / Overcommitted VM families team (N and E families). Previously, I worked as a part of the SCAN Cloud Performance team. Before joining Google, I was a Ph.D. student at the School of Computer Science, Carnegie Mellon University advised by Greg Ganger. My general interests are in designing scalable systems for cluster management and cloud computing using performance analysis and machine learning.

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 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 the first few days of my work.
