About

I am a PhD candidate at the University of British Columbia. My advisors are Professors Karthik Pattabiraman and Sathish Gopalakrishnan. My research interests are in Machine Learning Reliability, where I aim to develop the most effective ML detection and tolerance techniques against faulty training data in safety-critical applications.
I have previously worked in fault-tolerant computing systems, compiler optimizations, and software security techniques for IoT devices.
