I am a Soft Matter and Biophysics theoretical physicist, currently an independent postdoctoral fellow at the Center for the Physics of Biological Function in Princeton University. The common threads of my research are the study of emerging phenomena from simple local rules,  the use of “numerical experiments” on innovative toy models, and the search for elegant, geometrically intuitive interpretations.

Stochastic Force Inference: a method to infer the force and diffusion fields from noisy trajectories of overdamped systems, developed with Anna Frishman. Check out the 2020 Physical Review X paper and the GitHub package (in Python). 

Underdamped Langevin Inference: a similar inverse method for the underdamped case, developed with David Brückner and Chase Broedersz. Check out the 2020 Physical Review Letters paper and the Github package in Python

My PhD thesis, directed by Martin Lenz, can be found here.
