Alex Trevithick

I'm a CSE PhD student at UC San Diego, advised by Professor Ravi Ramamoorthi. I have spent time as a visiting researcher at the Max Planck Institute in the Visual Computing and Artificial Intelligence group. Before that, I graduated from Williams College with a double major in computer science and pure math. During my undergrad, I spent an amazing year at Exeter College, Oxford, where I worked with Bo Yang researching generalization in neural scene representations. I am currently interning at NVIDIA AI through Summer 2023.

I'm lucky to be supported by an NSF Graduate Research Fellowship, Jacobs School of Engineering Fellowship, and SHORE Fellowship.

I'm interested in machine learning and computer vision, especially visual intelligence and representing the 3D world from one or few images.

Real-time encoding and view synthesis from a single portrait image learned with strictly synthetic data.

Distill the knowledge of a 3D-aware conditional diffusion model into a triplane NeRF.

Per-pixel features improve NeRF and allow it to generalize to new scenes without retraining.
