I am a second-year CSE PhD student at the University of Michigan, advised by Prof. Andrew Owens. I have a general interest in computer vision, image processing, and visual forensics.

I graduated with a master's degree in ECE from the University of Michigan, during which I was advised by Prof. Justin Johnson.

I received a BS degree in Electronic and Electrical Engineering from Sungkyunkwan University, where I was advised by Prof. Jong Hwan Ko.

I have been working on an intersection of computer vision, image processing, and image forensics.

In my recent work Community Forensics, I study the generalization of fake image detectors by training them using images sampled from thousands of generators. In RGB no more, I train Vision Transformers directly from the encoded features of a JPEG image to accelerate the entire pipeline. In Auto-Tiler, I design an efficient compression scheme for over-the-network model inference.

We train fake image detectors using images from thousands of various generators to study generalization in detecting generated images.

We train ViTs directly from JPEG encoded features and accelerate train and eval by up to 39.2% and 17.9%.

We use autoencoders and show up to 67% higher accuracy and 81% reduced latency during network-constrained inference versus the image or video codec-based compression.
