I train vision models, develop aerial navigation methods, and build machine learning systems that run in real time.

01 / Selected work

From visual representations
to action.

01Foundation models

χViT & GeoCrossBench

I trained χViT, a self-supervised vision foundation model for remote sensing, entirely from scratch across multiple nodes. As first author of GeoCrossBench, I study how vision models generalize across satellite bands.

02Aerial robotics

Navigation with maps and memory

I develop and modify multimodal foundation models for drone navigation as vision-language-action models. My work combines map grounding, trajectory history, and simulation-generated data for instruction-conditioned action prediction.

Vision-language-action models · History-aware navigation · Synthetic training data

03Real-time vision

Video segmentation & matting

At Krisp, I co-led the development of real-time video segmentation for background replacement and built video matting models from scratch. I designed the project’s ML architecture across model development, training, and inference.
