Dr Sinha contributed to the field of analytical toxicology and his innovative contributions have been implicated in fields with wide scientific, medical and policy implications.  He developed a new tissue schizontocidal and gametcytocidal drug (6-methoxy-5,8 di-(4’-amini-1’-methyl butylamino quinoline) which is more active and less toxic than primaquine for treatment of Malaria. He established health risk assessment for fixing Maximum Residue Limit of pesticides in carbonated beverages (1ppb). This was adopted by the Joint Parliament Committee, Government of India to monitor pesticide residues in ingredients like sugar, thereby ensuring better standards and promoting exports contributing to the country’s economy. He developed a new biomarker (1-napthol) for estimation of acetyl cholinesterase enzyme and toxicants for measuring exposure to organophosphates and its effect which are crucial for the prognosis in real time to save lives of exposed victims. He reported Adefovir dipivoxil is a potent anti-viral drug for treatment of infested dengue viruses. He received prestigious Shakuntala Amirchand Award (ICMR) and international fellowships from ICMR &DHR, India and WHO. He has a patent to his credit. He worked in Toxicology Department, CDC Atlanta and was a visiting Professor at college of Medicine, Cincinnati University, USA. He honed degree in toxicology at OPCW Netherlands.
