Dr. Devanita Ghosh

I have an interdisciplinary background, with a Master’s in Microbiology and then a PhD in Organic Geochemistry from Linköping University, Sweden. I have participated and lead International and National (India) projects/ collaborations. I am also leading the Women’s Network Cell of Asia Oceania Geosciences Society. I am also working as Associate, Guest Editor and Reviewer of several reputed international journals.

Research

I am currently working on a Vidi project towards unravelling of the mechanisms of microbial Arsenic-removal by suppressed Fe2+ oxidation at Water Labs- Sanitary Engineering, CiTG, TU Delft. My background is Biogeochemistry.

Prior to starting my research, I spent 5 years as a Tenure track faculty at IISc Bangalore, India where I’ve worked on geochemical process that affect the subsurface mobilisation of arsenic and other hazardous elements in the groundwater of Indo-Gangetic plain.

My research project focusses on the chemical characterisation multiple recalcitrant biomarkers such as natural lipids that can be considered as environmental indicators/ proxies to understand a system. They can also can as paleoclimatic signatures. I also work on other non-recalcitrant biomarkers such as nucleic acids (metagenomics/ functional gene characterisation), proteins (meta-proteomics), amino acids and humic acids (Natural Organic Carbon- NOC) in various environmental niches. I try to understand the effect of hazardous elements on biological system and vice-versa.
