Hi, I am a fourth-year PhD student at the Technical University of Denmark at the Applied Mathematics and Computer Science Department. I am supervised by Jes Frellsen at DTU and Wouter Boomsma at DIKU(University of Copenhagen). My research is a part of the Centre for Basic Machine Learning Research in Life Sciences.

My recent internship at SonyAI with the Music Foundational Model team was fruitful! Interested in non-linear diffusion models, controllability and disentanglement? Read about our work here.

Currently, I am in New York collaborating with Rajesh Ranganath and Mark Goldstein at NYU. I am working on effective sampling techniques, controllability and modelling discrete data.

I am looking for internship roles staring in April-May 2025 for four to six months. Please reach out if interested.

Research Interests

Lately, I have been focusing on interesting problems in generative modelling. Specifically, I like to think about current challenges with Diffusion Models, like non-linear inference processes, simplifying guidance in pre-trained models, accelerating sampling and modelling discrete data. I also enjoy dabbling in structured modelling and scientific applications of diffusion models.

I have broad interests in the field of probabilistic modelling. I am enthusiastic about problems in Bayesian deep learning related to uncertainty quantification, variational inference and high-dimensional sampling. More generally, I like pondering about generalisation, distribution shifts and identifiability in deep probabilistic models. I wish I was better at differential geometry, measure theory and high-dimensional sampling. Works that aim to quantify or estimate uncertainty, model densities, or infer underlying structures/phenomena probabilistically, intrigue me.
