Žiga Kovačič

Undergraduate Researcher
@ Cornell University


I will be applying for PhD programs in Fall 2025!

I'm a Cornell University College Scholar pursuing a B.A. in Mathematics and Computer Science.

My interests lie at the intersection of physical simulation, machine learning (code generation), and tools for computer graphics.

I'm fortunate to work with Professor Kevin Ellis. Previously I worked with Abe Davis on time-lapse generation and modal analysis for resimulation.

Personal

In my free time I enjoy bouldering, cooking, and playing the guitar.
