My research focuses on world models, generative modeling, and
embodied intelligence, building systems that can reason about
geometry, dynamics, and interaction in a human-like way.
I am grateful to be supported by the ONR and REPRISM MURI, and
the ANR-3IA Artificial and Natural Intelligence Toulouse
Institute grants.
“Vutha” is my surname, “Chealyfey” is my
given name and “Lyfey” is the name I usually go by. On
a side note, my initials are “CV”, so I was destined
to do computer vision.
I am actively looking for PhD opportunities in the 2026-27
cycle to start in Fall 2027.

To be submitted
We study interpolation in diffusion and flow models by
following feature-aware geodesic paths, which enables smoother
and more semantically consistent transitions between generated
images.
