Faculty of Mathematics and Physics

Kanazawa, Japan

I am an applied mathematician that computes dynamics and uses dynamics to compute. The first topic is related to biomechanical models as well as a dynamics driven perspective on AI. The second topic is my main focus and lies in the domain of physical reservoir computing which is a framework that utilizes natural physical phenomena to perform computations.

I am an Adjunct Assistant Professor at Temple University Japan Campus. But I am still supervising a large body of Master and Phd students at Kanazawa University. If you are interested in getting involved with our research projects you are welcome to shoot me an email.

For my research I mainly use Python. I have worked on a couple of mechanical and material science problems in collaboration with industry, and I am always on the look for new collaborations.

My position(s) will end beginning of March 2027 although I am in the loop for many jobs I still would be very grateful if you could contact me for any research job openings that fit my profile.

I am an organizer of the Differential Equations for Data Science seminar DEDS, if you want to join our seminar mailingslist click here. I am also an organizer of the Dynamical systems Study Group. This is an online open study group, please contact me if you are interested in participating

As a first generation university graduate with a lower class background I very strongly believe in a grass-roots approach to science. I am very supportive of open-source. I think that a delta-function perspective on research is outdated in the age of model-free methods.
