Biography

I am a PhD student in the Department of Computer Science at Aalto University, advised by Arno Solin and Markus Heinonen. My research interests include diffusion generative models, (physics-inspired) inductive biases in diffusion models, and also applications of machine learning in the natural sciences. Previously, I also worked in the intersection of deep latent variable models and causal inference. I was also one of the main organisers of ELLIS Doctoral Symposium 2023!
