Kannan Pakshirajan obtained BPharm from the Tamil Nadu Dr M.G.R. Medical University and MTech in Biotechnology from Jadavpur University. He obtained his PhD in Chemical Engineering from IIT Madras. He was a BOYSCAST Fellow at the IHE Delft Institute for Water Education, The Netherlands. As an Environmental Biotechnologist he has been intimately associated with toxicity removal in air, soil and water environment. He joined IIT Guwahati in 2004 and has spent over 18 years of teaching and research focusing on technologies to treat contaminated environment and toxicity removal. He has served as a Visiting Researcher in the discipline of Microbiology at National University of Ireland Galway. He is ‘DBT Nominee’ for the Institutional Biosafety Committee (IBSC) constituted at North Eastern Hill University, Shillong, Meghalaya. Pakshirajan has made significant contributions to environmental biotechnology with over 200 publications and 2 edited books.
