I am a third-year PhD student at MIT, where I am advised by Prof. Russ Tedrake in the Robot Locomotion Group.
My research aims to scale realistic simulations for generating training data and evaluation benchmarks for robotic manipulation foundation models. I enjoy combining model-based and learning-based methods to tackle this challenge.
Before joining MIT, I completed my MEng at Imperial College London and spent nine months at Ocado Technology, where I worked on parallel yaw pick-and-place systems at scale.
Outside of academia, I am passionate about rock climbing, backpacking, Latin social dancing, and specialty coffee.

Outside the Lab
I enjoy staying active in my free time. These days, that means bouldering several times a week. In the past, I competed in long-distance running, rowing, and Latin social dancing. During holidays, I often trek, backpack, or cycle in different parts of the world.
