Yotam Smilansky

I am a Lecturer in Dynamical Systems and Analysis at the Department of Mathematics at the University of Manchester. My main research interest is the study of tilings, aperiodic order and mathematical models of quasicrystals, the associated dynamical systems and their interactions with number theory. Before joining the University of Manchester I was a Hill Assistant Professor at Rutgers University and an Orzen Postdoctoral Fellow at the Hebrew University of Jerusalem. I completed my PhD at Tel-Aviv University under the supervision of Professor Barak Weiss.

I am a co-organiser of the Manchester Dynamical Systems and Analysis Seminar.
