Tristan Stevens
Hi!
I am a postdoctoral researcher at Eindhoven University of Technology (TU/e). I research the use of generative models for signal processing applications, ranging from medical imaging to semiconductor manufacturing and automotive radar. My research interests are centered around fundamental probabilistic machine learning techniques and the possibility of integrating them with classical signal processing methods. I am the co-creater of the zea Python package for cognitive ultrasound imaging. Currently, I am also a member of the EURASIP Academy. Besides my research, I love to play guitar, trumpet, chess, code, and climb rock.
This website serves two purposes. Beside an overview of my work, I also try to post some interesting articles on things I learned or figured out that might be useful to anyone.
