Biographical Details
Arindam Saha

In February 2024, I joined the Department of Statistical Science at University College London (UCL) as a Senior Research Fellow in Uncertainty Quantification in the SEAVEA project. I am focused mainly on multi-physics problems and the propagation of uncertainties when coupled models are emulated.

Before my appointment here, I worked at Brunel University London as a part of the same SEAVEA and STAMINA projects and co-developed the FACS model for infectious diseases and the FabSim3 automation toolkit for complex simulation tasks. I have also worked at the University of South Florida in Tampa, Florida on creating a digital twin for infectious disease modeling in cities, and at the University of Sheffield on analyzing swarm dynamics and collective behavior models.

During my PhD and undergraduate days, I have worked on various aspects of complex dynamical systems such as extreme events, synchronization, routes to chaos in discrete maps, and coupled networks.

Research Interests

Currently, I am interested in developing,  analyzing, and validating large-scale coupled models and running them on HPCs in a computationally efficient way. As a part of this process, I have been using emulators and experimental design techniques to quantify the uncertainties associated with emulation.
