## Research

*Research interests*:

– Numerical linear algebra

– Tensor networks

– Non-convex and Riemannian optimization

– Machine learning

Generally I’m interested in tensors and numerical linear algebra with a focus on applications to machine learning. Currently I’m working on developing a streaming sketch algorithm for tensor trains. This will make it feasible to compute tensor train decompositions of very large tensors in a distributed setting.

On the weekends I like to study topics in data science, bioinformatics and scientific computing to broaden my knowledge. I do this by either taking online courses, reading text books, or doing small programming projects. For the latter I usually write blog posts on this website.

## Open source contributions

## Work experience

**March 2018–December 2022 (expected)**:

PhD student at *University of Geneva*.

I was working in pure mathematics from 2018 until early 2020, when I switched research direction to applied math. Over the past few years a significant fraction of my time is spent writing research code in Python, both numerical code and code for computer algebra. I spend about 20% of my time teaching. I also spend about 20% of my time studying to broaden my knowledge about data science and scientific computing, either by doing online courses, reading text books, or doing small programming projects.

**May 2021–present**:

Senior Scientific Editor at *The Science Breaker*.

The goal of this journal is to make the core ideas behind published scientific research accessible to a wide audience to foster interest in science. It is also an excellent and informal way for scientists to get a flavor of the research and scientific methods of very different fields. As an editor I propose new articles and edit them to make them easier to read for laypersons.

**2014-2016**:

Teaching assistant at *Utrecht University*.

I was a teaching assistant for four different courses during my time as a student at Utrecht.
