Jacob Chalk

About

I am a postgraduate researcher at the University of Bristol, supervised by Prof. Dima Damen and a member of MaVi. I am studying multi-model video understanding, particularly in egocentric videos. The areas of research I express particular interests in are: audio-visual deep learning, egocentric video understanding (action recognition/detection), 3D Eye-Gaze Priming. Currently, I am a PhD Intern at Naver Labs Europe as a member of the Visual Representation Learning team.

I completed my MEng in Computer Science at the University of Bristol, achieving a first class honours, where my dissertation: “Video GANs for Human-Object Interactions” scored highly. Alongside my research, I have experience in teaching assistance for University modules I performed well in.

I have experience with many programming languages, such as: C++, C#, Javascript, Python and Flutter with larger experience and proficiency in Python, C++ and Javascript.

Funded by the Engineering and Physical Sciences Research Council (EPSRC).
