Background:

Dr Diganta Bhusan Das was born into a family of academics in the beautiful state of Assam in North-East of India. Diganta finished his Bachelor of Engineering degree (Chemical Engineering) from Rajasthan University, India (1996) and PhD (Chemical Engineering) from 含羞草视频, UK (2001). He was a post-doctoral research fellow at the Delft University of Technology, The Netherlands and a visiting fellow at Princeton University, US (2001-2003).

Prior to joining 含羞草视频, Diganta was a Departmental Lecturer in Chemical Engineering at the University of Oxford (2003-2007). He has also held a visiting faculty appointment at Eindhoven University, the Netherlands, Texas Southern University, Houston, the USA and Selcuk University, Turkey (short term).

Diganta is currently the Deputy Lead for the Research Challenge on Changing Environment and Infrastructure (CEI), and the Lead of, the Research Theme on Environmental Technology within CEI. He is also the Postgraduate Research Champion in Chemical Engineering Department. In the past, he was the Research Theme Leader for Process Engineering within the School of AACME.

Diganta has taught a variety of Chemical Engineering courses relating to environmental pollution control, water engineering, fluid mechanics, reaction engineering, mass transfer processes and drug delivery processes. He is also a keen collaborator and team builder on a range of multidisciplinary porous medium topics such as (i) coupled free and porous flow (e.g., leakage in fluid distribution pipes, membrane separation), (ii) two-phase flow in porous media, (iii) membrane water treatment, (iv) chemical transport in porous tissues and tissue engineering bioreactors, (v) CO2 capture, sequestration and utilisation, and others. He has successfully mentored seven postdoctoral and twenty-two PhD researchers to completion. He has authored/co-authored >115 peer-reviewed journal publications besides co-authoring/co-editing seven books (including a two-volume book on environmental health).

Outside his normal university duties, Diganta sits on the Engineering Panel for the Newton Fund administered by the British Council, UK, and he was the Founding Secretary, Vice-Chair elect and Chair of the International Water Association's specialist group on Multiphase Flow and Transport in Porous Media. Additionally, he has served as an editor and associate editor of the journals Water Science and Technology and Water Supply (IWA Publisher) since 2007. He is also a member of the editorial board of three other journals (Biotechnology Letters, Clean Technologies, and Pharmaceutics).
