Biography

Devendra Saroj graduated (B.Tech. in Civil Engineering, 2002) from Indian Institute of Technology (IIT)-Roorkee (India), and completed M.Tech. (Environmental Engineering and Management, 2004) from IIT-Kanpur (India). He obtained doctoral degree (2007-8) in Environmental Engineering from University of Trento (Italy). He contributed to EU funded project (FP6: EUROMBRA) on Membrane Bioreactors (MBRs) during and after his PhD at University of Trento. Prior to joining Surrey, Devendra worked at UNESCO-IHE (Delft, Netherlands) as a lecturer in wastewater engineering.
