I lead a research group at the Institute for Infocomm Research (I2R), A*STAR, focusing on data-efficient deep learning. Our work is inspired by applications in healthcare and manufacturing where collecting large, well-annotated datasets is often time and cost-prohibitive due to the need for careful expert labelling.

I earned a BS ('08), MS ('12) and PhD ('17) in Computer Science from Stanford, where I had the privilege to work with Professors Anshul Kundaje, Daphne Koller, Andrew Ng and Serafim Batzoglou on machine learning and deep learning for biology. I took a year off during my PhD to work for Counsyl, where I developed software (variant calling and LIMS integration) for clinically validated sequencing-based genetic tests.
