I am a PhD student at Blender Lab at University of Illinois, Urbana-Champaign (UIUC), currently advised by Prof. Heng Ji. I obtained my Masterβs from the Graduate School of AI at KAIST, under the supervision of Prof. Sung Ju Hwang. If you are interested in collaborating with me on research projects, please contact me! Here is my CV.
My primary research interest includes:
- Model Interpretability & Robustness
- Vision Langauge Models (VLMs)
- Efficient Machine-learning
