Brief bio
I am a PhD student at WSAudiology and the Technical University of Denmark (DTU). I am interested in probabilistic approaches to deep learning - especially deep generative models of sequential data and machine learning applied in health technology. Currently, I primarily research how we can make audio models that generalize to real-world use scenarios. Specifically, I've been working on variational autoencoders and how probabilistic modelling enables us to, e.g., learn robust latent representations, incorporate prior knowledge, and utilize uncertainty quantification. Below is a collection of some recent work and news.

Recent Work and News

UC Berkeley/ICSI stay: Continuously deep hierarchical VAE

I'm visiting Berkeley working with M. Mahoney. We are developing continuously deep hierarchical variational autoencoders by combining neural stochstic differential equations with hierarchical variational autoencoder models.

Directional archetypal analysis

Multi-subject, multi-modal modelling of functional neuroimaging data using directional statistics. Published in Frontiers in Neuroscience (paper, Twitter thread).

VI-TasNet

The Variational Inference Time-domain Audio Separation Network (VI-TasNet) is probabilistic extension of TasNets. The work shows how we can incorporate domain-knowledge priors in modelling and quantify separation performance uncertainty unintrusively. We also investigate how speaker separation generalization can be understood through the lense of rate-distortion analysis.

Research Pitch Battle winner

I won Danish Sound Days research pitch battle competition, see their post on the competition above.

Client adaptation in federated learning

We present a federated learning approach for learning a client adaptable, robust model when data is non-identically and non-independently distributed (non-IID) across clients, as well as a way to simulate non-IID clients.

Deep unsupervised learning course

I organized and helped teach a course on deep unsupervised learning at DTU, modelled on the Berkeley CS294-158.

Interactive machine learning demos

I developed a series of machine learning demos for an introductory machine learning course at DTU .

Danish Foreign Ministry's World Image Grant//Visiting biomedical engineer in Nepal

We received a grant of 7k EUR for the production of a documentary for an alternative view on a developing country. Through Engineering World Health at DTU I was deployed at Okhaldhunga Community Hospitals. My work at the hospital entailed hospital equipment repair, healthcare staff training (proper use and maintenance), and needfinding (initial phase design research and planning). Photo by S.
