Dr. Rajeev Jain is Senior Scientist of Forensic Toxicology at Central Forensic Science Laboratory, Ministry of Home Affairs, Govt. of India. He has more than 10 years of research experience in the field of analytical toxicology. During his tenure as Forensic Toxicologists, he has examined post-mortem samples of more than 500 medico-legal cases pertaining to drug overdose and poisoning. He has obtained his Ph.D. degree in Analytical Toxicology from CSIR-Indian Institute of Toxicology Research (India). His research work is focused on Development of simple, rapid, eco-friendly, cost-effective, sensitive and selective analytical methods based on microextraction techniques (such as SPME and DLLME etc.) for the determination of chemical analytes for forensic toxicological, clinical and environmental importance in various complex samples such as blood, saliva, plasma, urine, tissue etc. using GC-MS, GC-FID, HPLC, GC-ECD and TLC-image processing technique. He has published many research papers, review papers and book chapters in various referred journals on this subject. He was one of the first scientists to explore the possibility of coupling dispersive liquid-liquid microextraction with injector port silylation for rapid analysis of polar toxicants. He is also acting as invited reviewer in various referred journals and on the editorial board of various open access journals of Toxicology and Chromatography. Dr. Ritu Singh is an Assistant Professor in Department of Environmental Science, School of Earth Sciences, Central University of Rajasthan, Rajasthan, India. Her research interest includes analytical method development, microextraction techniques, nano-remediation, environmental monitoring and assessment. She received her doctorate degree in Environmental Science from Babasaheb Bhimrao Ambedkar University, Lucknow. She worked as research fellow in CSIR-Indian Institute of Toxicology Research for five years and made significant contribution in the field of nano-remediation. She has published her work in several international journals of repute and has contributed several chapters in international and national books. She also has one international book to her credit. She is the recipient of ‘DEF-Young Scientist Award’ in the field of Environmental Science. She is an editorial board member of Journal of Nanoscience, Nanoengineering and Applications, Journal of Water Pollution & Purification Research & Eurasian Journal of soil science. and invited reviewer of several refereed journals. She is also serving as life member of various academic bodies.
