Wieger Punter

PhD Candidate

About

I am a PhD researcher at Eindhoven University of Technology, working on algorithms and data management for high-volume data streams. My research focuses on designing scalable, memory-efficient methods for analysing multidimensional and continuously evolving data. My work combines theoretical algorithm design with practical implementation in data-intensive systems. I am also interested in applying these methods to interdisciplinary challenges, including the analysis of environmental and geospatial data.

Personal Interests

To whom it may concern, here are some of my personal interests.

Climbing outdoors

Climbing

You can find me frequently in the bouldering and climbing hall in Eindhoven. I'm always up for outdoor climbing activities as well, mostly in the Ardennes.

Playing guitar

Music

I love playing music. Last gig was a piano & violin duet at my own wedding, together with my partner. Recently picked up my guitar lessons again!
