Department of Digitalization



Rajani Singh is a Postdoctoral Researcher at the Department of Digitalization at the Copenhagen Business School (CBS). Her research field includes Blockchain, Game theory, Mathematical Economics, Optimization Theory and Cryptography. Her research bridges between Game theory, Blockchain Technology and Cryptography.

She holds a PhD in Mathematics from the University of Warsaw, Poland and M.Sc. in Mathematics from Indian Institute of Technology Delhi, India. She has been appointed as the Principal Investigator of the Project Games dynamic modeling ’tragedy of the common resource’ funded from Funds of National Science Centre, Poland.

Before joining CBS, she has worked as a full time Visiting Researcher at the University of Waterloo, Ontario, Canada, Research Associate at the Brandon University, Manitoba, Canada and Visiting Research Scholar at the Institute of Computer Science, Polish Academy of Sciences, Warsaw, Poland.
