About Me

PhD Student @ Aalto University

MSc @ ETH Zurich

I am a computer vision PhD candidate from Finland 🇫🇮. I was a research intern at Niantic Spatial in London in Summer 2025, and I will return for another internship in Summer 2026. I also work part-time at a Finnish-based stealth startup 🥷. I am advised by Juho Kannala and Arno Solin. Feel free to reach out for research or business inquiries.
