I am a MSc Computer Science student at ETH Zurich, specializing in Machine Intelligence. Previously, I interned at Apple in London working on distributed machine learning, finished my undergrad in Computer Science at ETH Zurich, and worked on research at the intersection of machine learning and neuroscience.

Feb - Aug 2026
Machine Learning Engineering Intern
I worked on integration and optimization of distributed ML and built Thunderbolt Collective Communication Library (TCCL) - a low-latency PyTorch-native collective communications backend for Apple Silicon. London, United Kingdom
2025/26
Student Researcher
Developing at the intersection of machine learning and neuroscience. I worked on deep learning methods for reconstructing eye-movement scanpaths from brain signals.
Supervised by Ard Kastrati and Martyna Plomecka in Prof. Nicolas Langer's UZH Methods of Plasticity Research Group.
