Risha joined Anglia Ruskin University as Lecturer in Forensic Chemistry in August 2022. In her previous jobs she has worked as Assistant Professor in Forensic Science at Galgotias University, Greater Noida, Uttar Pradesh, India, as a Junior Analyst at the National Dope Testing Laboratory under the Ministry of Youth Affairs & Sports, Government of India, and as an intern at the Chemistry Division of the State Forensic Science Laboratory under the Ministry of Home Affairs, Government of India. She has a BSc Honours degree in Chemistry, an MSc degree (Gold medallist) in Forensic Science, and a PhD degree in Toxicology.
Risha’s research interests lie in analytical chemistry, toxicology, and forensic sciences. She has previously worked on various toxicology projects including the analyses of drugs and heavy metals from various matrices such as water, human viscera, and body fluids.
Her experience in research supervision includes supervising MSc dissertation projects and PhD research projects on Forensic Toxicology.
Risha’s PhD work was supported by funding from a Deans Bequest Grant, School of Biomedical Sciences, Division of Health Sciences, and a Doctoral Scholarship from the University of Otago, Dunedin, New Zealand.
