Hi, I'm Arnold.

I'm a PhD student in computer science at Princeton University advised by Olga Russakovsky. I work on controlling and accelerating generative processes, with connections to computer vision, molecular dynamics and cognitive science. I work closely with Timothy Buschman and Roberto Car.

I graduated from Columbia University in 2025 and my undergraduate research was in computer vision and machine learning for biomedical applications. I was advised by Carl Vondrick, Elias B. Issa at the Center for Theoretical Neuroscience and Mary Salvatore at Columbia Irving Medical Center and supported by the I.I. Rabi Scholars Program.

During this time, I also worked with Pranav Rajpurkar at Harvard Medical School, and Kaoutar El Magharoui at IBM Research.

Below is a summary of my undergraduate research and teaching.
