About Me

Welcome to my personal webpage!

I am a (soon to be postdoctoral) researcher at IST Austria working with Monika Henzinger. Prior to that, I was a PhD student at University of Copenhagen where I was fortunate to be advised by Rasmus Pagh and affiliated with BARC. I am interested in algorithmic differential privacy broadly, and problems in the continual observation setting in particular. From January through April 2025, I had the privilege of visiting Adam Smith at Boston University.

Prior to starting my PhD, I received my master’s degree in Engineering Physics from Lund Unversity in 2020. Parts of my master were spent modeling beam dynamics at CERN. After graduating I had a stint as a Software Engineer at Ericsson, implementing 5G protocols in Downlink L1.

In my spare time I enjoy running, live music, and craft beer.
