S. Sridhar

Member of Technical Staff

Sridhar received his B.Sc. in Physics at D. G. Vaishnav College (University of Madras) in 2001 and obtained his M.Sc. in Physics from IIT Madras in 2004. His PhD in Physics, carried out at the Institute of Mathematical Sciences, Chennai, involved investigating the nonlinear dynamics of pattern formation and control in biological systems such as the heart and was awarded in 2011.

Sridhar did a Postdoc in pattern formation at the Chemistry Department at Brandeis University, Waltham, MA. He joined Scimergent Analytics (now known as Scisphere) as postdoctoral scientist in 2013 to work on an data-driven approach to study patterns of urbanization and economic networks in India. During 2015-2016, he worked as a Pegasus Marie Curie Postdoctoral Fellow at the Department of Physics, Ghent University, Belgium. In 2014 he co-authored a book titled “Patterns in excitable media: Genesis, dynamics and control” (published by CRC press).

His research interests include modelling complex systems across different domains spanning natural sciences, engineering, economics and social sciences, using tools and techniques from nonlinear dynamics, high performance computation, complex networks, and data-driven modelling.

Alexandre Reiffers


Alexandre received his B.Sc. degree in Mathematics from the University of Marseille in 2010, his Master degree in Applied Mathematics from the University of Pierre et Marie Curie in 2012 and his PhD in Computer Science from INRIA (National Research Institute in Computer Science and Control) and the University of Avignon in January 2015.

From July 2016 to December 2017, Alexandre Reiffers was a researcher at SafranTech, where he was working on comparison of maintenance strategies.

Most of his research projects concern the application of mathematical tools (game theory, optimization, stochastic process and machine learning) for a better understanding of real-world problems. The different issues that he studied touch topics such as social networks, speech between human and computer, economy and manufacturing.

During his stay at RBCCPS he is applying dynamic games (differential games and mean-field games) in smart grids. More precisely, he is studying demand-side management for residential homes, where the planner aims to reduce consumption by providing energy-efficient equipment and encouraging energy aware consumption. He is also working on maintenance strategies for manufacturing assembly line.
