As a member of the environmental fate team, Dr. Acharya conducts environmental risk assessments for industrial chemicals and biocides as part of the regulatory requirements for these compounds (Commission Regulations 1907/2006 and 528/2012). He assists with the preparation of assessment reports and dossiers for EU and national regulatory authorities for both Biocidal product and active substance renewals. 

Prior to joining Exponent, Dr. Acharya worked as a post-doctoral researcher with Environmental Engineering research team at Newcastle University and played a leading role in assembling a portable toolbox called "Lab in Suitcase" for real-time and on-site in-depth microbial hazard surveying. He has experience in using multitude of techniques and data analysis tool for water quality and quantity surveying, pollution source tracking in the river basin management, hazard mapping, microbial risk assessment and ecosystem services. Dr. Acharya holds a Ph.D. in Environmental Engineering from Newcastle University. His Ph.D. research provided the basis for a rational framework to establish and calibrate QSBR models that can be applied to predict biodegradation rates and ultimately the half-life of a given chemical, which is the endpoint used for persistence assessment of chemicals. In addition, his research also provided an insight on the microbial ecology of putative degraders for a given environment and their relationship with chemical biodegradation.
