I want VLA policies to hold up inside real robot control loops, which means three things at once: training that transfers across embodiments, inference cheap enough to run every control step, and failures caught early enough for the policy to recover.
Structured pruning leaves a model that has to relearn what was removed. I work on giving that recovery enough capacity, and on scheduling compression so the error that accumulates in deeper layers is paid down first (EMNLP 2026).
Making vision models cheap without giving up accuracy: re-parameterization at branch level (ACCV 2024), transfer that keeps a vision-language model general (BMVC 2026), and test-time adaptation that verifies candidate labels instead of adjusting predictions (NeurIPS 2026). The same drive won Track 1 of the 2025 IEEE Low-Power Computer Vision Challenge.

Changing what the policy is trained to predict, so skills carry across robots instead of binding to one.
Cutting the compute spent on every control step while keeping task success.
Noticing that an action is going wrong early enough for the policy to recover.
Letting regularization respond to the data instead of applying one fixed strength.
I built and operated our lab's GPU cluster, which consists of about 20 nodes with eight RTX 3090s each. This work included containerized provisioning, per-node CUDA isolation, and training jobs that ran unattended for days. Outside of research, I taught AI tutorials for undergraduate research assistants and helped launch the Google Developer Student Club chapter at Ajou University.
