A Ph.D. Student at Johns Hopkins University, I am a member of the Advanced Robotics and Computationally Augmented Environments (ARCADE) research group and the Computational Interaction and Robotics Laboratory (CIRL). My research interests include computer vision, reinforcement learning, and domain generalization, with a focus on applications in robotic manipulation, medical imaging, and clinician-centered surgical robotics.

Machine Learning and Large Scale Data Analysis, Department of Computer Science, University of Chicago, Chicago, IL, USA
- With Prof. Yali Amit.
- Wrote supplementary course material and held weekly lab sessions.
Selected review: “Ben was incredibly patient during office hours and always responsive to student questions. In addition, he often presented demos during office hours or showed easier ways to handle the homework assignments; both were very helpful.”
