Dhirendra Pratap Singh is currently a Scientist in Neurotoxicology and Immunotoxicology Laboratory of the ICMR-National Institute of Occupational Health, Ahmedabad, India. He earned PhD in Pharmaceutical Sciences from Panjab University in Chandigarh and worked as a research fellow at the DBT-National Agri-Food Biotechnology Institute (NABI) in Mohali during his PhD, focusing on "cobiotics," a specialized combination of prebiotics and antioxidants intended for food-based applications and gut microbial modification to improve metabolic health. After a brief period as a post-doctoral researcher at the University of Gothenburg in Sweden, he joined ICMR-NIOH in Ahmedabad as a Scientist. His current research interests include: i) host-gut microflora interactions in neurobehavioral aberrations related to heavy metal toxicity, ii) the development of cost-effective diagnostics for exposure to these metals, and iii) the environmental impact of pharmaceutical industry clusters on the emergence of antimicrobial resistance (AMR). He is an experienced experimental pharmacologist with a particular interest in environmental toxicology, focusing on both legacy and emerging endocrine disruptors, such as bisphenols and other plasticizers, often referred to as "forever chemicals."
