Gourab Ghoshal is Assistant Professor of Physics and Astronomy with joint appointments at the departments of Computer Science and Mathematics. Prior to joining Rochester, he was at Harvard University at the department of Earth and Planetary Sciences and a member of Harvard’s multidisciplinary Origins of Life initiative.

Hailing from New Delhi, India, Professor Ghoshal got his bachelor’s and master’s degree at the University of London, UK (BS and MSc in theoretical Physics, 2004). He did his doctoral-thesis work at the University of Michigan, Ann Arbor (PhD in Physics, 2009) during which he attended the prestigious Complex Systems summer school at the Santa Fe Institute, NM and the Theoretical Physics school at Les Houches near Chamonix in France. Following his PhD, he was a postdoctoral scientist jointly at Northeastern University and Harvard Medical School as well as a visiting scientist at the Media Lab, MIT. Professor Ghoshal is trained as a Statistical Physicist and works in the field of Complex Systems. His research interests are in the theory and applications of Complex Networks as well as Non-equilibrium Statistical Physics, Computational Social Science, Econophysics, Dynamical Systems and the Origins of Life.

Hugo has a bachelor’s and master’s  degrees in Computer Engineering at the Polytechnic School of Pernambuco, Brazil. He got his Ph.D. in Computer Science at Florida Institute of Technology in 2016. His research interests are mainly centered around understanding the fundamental mechanisms underlying complex human dynamics such as human mobility and online behaviors.

Apart from his research activities, he has a strong interest in Philosophy, Politics and cinema. His worldview has been shaped by a convolution of Albert Camus, Rollo May and Karl Marx with orthogonal influences of Pedro Almodóvar, Gaspar Noé and Lars von Trier.
