I am an Associate Professor of Business Analytics at Southampton Business School, the University of Southampton and a member of the Centre for Operational Research, Management Sciences and Information Systems (CORMSIS). I am honoured to be listed as leading academic data leader 2021 by CDO (Chief Data Officer) Magazine.
In my professional community, I am serving as an associate editor for the Journal of Simulation, area editor for Health Systems journal, a General Council member of The OR Society, the chair of The OR Society’s Special Interest Group in Simulation, and a coordinator of Agent-Based Simulation track at the Winter Simulation Conference (since 2018). In terms of teaching, I am a Senior Fellow of the Advance HE (formerly, Higher Education Academy) and serving as the external examiner at the University of Bath School of Management for MSc programmes in the School of Management and the MRes in Management element on the Integrated PhD.
My research interests lie in the areas of simulation and its interface with other Analytics methods. I am particularly interested in simulation modelling methodology (symbiotic simulation, hybrid modelling, agent-based simulation, discrete-event simulation, simulation optimisation) with applications in supply chain management, operations management and health and social care.
