Dr. Rajeev Jain is Senior Scientist (Forensic Toxicology) at Central Forensic Science Laboratory, Ministry of Home Affairs, Govt. of India. He has more than 12 years of research experience in the field of analytical toxicology. During his tenure as Forensic Toxicologist, he has examined post-mortem samples of more than 600 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 sustainable, affordable, and green analytical methods based on microextraction techniques for the determination of chemical analytes for forensic toxicological, clinical, and environmental importance in various complex samples. Dr. Abuzar Kabir is a Research Associate Professor in the Department of Chemistry and Biochemistry at Florida International University, Miami, Florida, USA. His research focusses on the synthesis, characterization and applications of novel sol-gel derived advanced material systems to be used as chromatographic stationary phases, surface coatings of high-efficiency microextraction sorbents, nanoparticles, microporous and mesoporous functionalized sorbents, molecularly imprinted polymers for analysing trace and ultra-trace level concentration of polar, medium polar, nonpolar, ionic analytes, heavy metals, and organometallic pollutants from complex sample matrices.
