About

I am a Senior Software Engineer @ Google Research. My current work focuses on computer vision, mainly on instance-level recognition/retrieval. I graduated with a Ph.D. from Stanford University in 2016, working on image and video retrieval, under the supervision of Prof. Bernd Girod. During my time at Stanford, I also worked on image classification and compression. I am a Fulbright Science & Technology Scholar and an Accel Innovation Scholar. On the science outreach side, I co-founded and was an editor of The Global Scientist online magazine.
