Dr. Trupti Das, Chief Scientist & Chairperson, HRD 9438676607, truptidas@immt.res.in , https://truptidas-immt.weebly.com/people.html

DESCRIPTION :

Did my masters in Microbiology and I worked as a CSIR-Senior Research Fellow at CSIR-IMMT to complete my PhD in the area of applied environmental microbiology. Thereafter I had the opportunity to join CSIR-IMMT as a scientist in 2004 and have been working in various government sponsored and network projects as a member and a leader. I worked as a visiting scholar at the University of Utah, USA in the area of Enhanced Biological Phosphorus Removal during 2007-2008. My current research area includes development of sustainable processes for biological treatment of industrial and municipal wastewater. A part of my research pursuit also includes the study of atmospheric aerosols and trace gases and their overall impact on the regional atmosphere.
