Othon Michail is an Assistant Professor at the Department of Computer Science of the University of Liverpool (UoL) since 2016. He is also a member of the research team of the Leverhulme Centre for Functional Materials Design and a member of the council of the Networks Sciences & Technologies initiative (NeST). His research interests are Distributed Computing, Algorithms and Complexity, Computability, Algorithmic Theory of Dynamic Networks, and Programmable Matter. In 2017, he started and is leading since then the "Programmable Matter" initiative at the UoL, an interdisciplinary collaboration between CS, EEE, the School of Engineering, and external collaborators. He has been awarded a Royal Society International Exchanges award together with Prof. Julien Bourgeois. He is currently supervising and co-supervising 4 Ph.D. students whose work is related to programmable matter. His work within this area focuses on formal models, the design and analysis of centralized and distributed reconfiguration algorithms, and feasibility and complexity characterizations.
