Hi! I’m a computer science PhD candidate at Stanford University, where I work as a member of the Stanford AI Lab. I’m advised by Chelsea Finn and Jiajun Wu and affiliated with the StatsML and SVL groups. My research and education is generously supported by a Sequoia Capital Stanford Graduate Fellowship and an NSERC Postgraduate Scholarship (Doctoral). I’m a proud Taiwanese-Canadian.
My research primarily focuses on representation learning in the context of robotics, but I also nurture a broad interest in AI.
Previously, I majored in robotics as an Engineering Science undergraduate at the University of Toronto. During this time, I did research at the Vector Institute with Roger Grosse and Dan Roy. I’ve also spent time at Google Brain with Shane Gu, Berkeley AI Research with Sergey Levine, and the Max Planck Institute for Software Systems with Rupak Majumdar.
Latent quantization imposes a strong inductive bias towards learning disentangled representations.
Instrumenting manipulators with hand-centric sensing facilitates out-of-distribution generalization.
A simple yet effective unsupervised meta-learning pipeline for image classification pre‑training.
Efficient controller synthesis for reachability and safety specifications via on-demand abstraction construction and adaptive spatiotemporal resolution.
Foundation models are pre-trained, self-supervised, large-scale, multi-modality models that exhibit emergent functionalities and homogenize deep learning models.
Marrying Hamiltonian Monte Carlo with annealed importance sampling results in an unbiased estimate of marginal likelihood that supports pathwise derivatives. Surprisingly, stochastic gradient annealed importance sampling turns out to be inconsistent.
State-of-the-art nonvacuous PAC-Bayes generalization bounds for neural network image classifiers.
A meta-learning agent develops an adaptive curriculum of visuomotor tasks by deep clustering its own trajectories.
