He was also a Post-Doc Fellow at the Univ. of Alberta, Computer Process Control Group, Chemical & Materials Dept. (2005-06). Dr. Roy had joined BARC soon after his graduation and had worked there for three decades as an Instrumentation Engr. in the Research Reactors at BARC, where he had specialized in system/equipment fault diagnostics & predictive maintenance techniques and application of various mathematico-statistical & Bayesian approaches for total-maintenance-management of plants. He had subsequently served as a CMD of BHAVINI (a PSU under the Dept. of Atomic Energy, Govt.of India), from 2016  to 2021, where  apart from his primary assignments on Project Management & Corporate Governance, Dr. Roy was working on Health Monitoring techniques for structures & roto-dynamic equipment, Bayesian Forecasting & Optimization studies for system commissioning and  for  evolving the concepts of Technology Forecasting, Sustainability Engg.  along  with Human Reliability & Cybernetics.

Dr. Roy, retired from  GOI service, in January 2021 and has since been associated as a Research Advisor & Guest Faculty with the Systems Group, Dept. of Chemical Engg., IIT-Madras. Presently, he offers a semester level course on Modern Control Theory  and co-guides PhD & Post-Doc fellows on aspects of De-noising & Estimation of Air-Pollution  Measurements & Battery Management Systems, Networked & Distributed  Controls, Critical Transitions in Complex Dynamical Systems (as an extension to the problems of fault diagnostics in linear time-varying systems)  and Game-theoretic formulations on pollution mitigation policy formulations.

Dr. Shaik Vazeed Pasha is a Research Scientist at the National Institute of Advanced Studies (NIAS) and Co-Project Lead for the initiative “Develop Natural Resource Utilization Plan for Biodiversity Hotspots.” He also an external Associate professor at The University of Trans-Disciplinary Health Sciences and Technology (TDU), Bengaluru. He holds a Ph.D. in Environmental Sciences from NRSC–ISRO, Hyderabad, in collaboration with Andhra University. With over 11 years of experience, he has contributed to 12+ national-level projects across institutions like ISRO, NIAS, and IIT Kharagpur. As Co-Principal Investigator, he successfully led the IWST-ICFRE Government of India-sponsored project “Study of Climate-Driven Effects on Indian Forests Through Long-Term Monitoring.” His research focuses on spatial biodiversity, natural resource management, biomass and carbon stock estimation, and forest disturbance regimes, supported by 40+ international publications and 954+ citations.

Dr. Pasha has conducted extensive fieldwork across diverse Indian ecosystems, including the Western and Eastern Ghats, Eastern Himalayas, mangroves, and arid zones. He actively mentor’s young researchers, reviews for reputed journals, and has guided over 35 interns in geospatial analytics. He represented India at the 8th BRICS Young Scientist Conclave (2023) and is affiliated with Global Forest Biodiversity Initiative (GFBI) and Science-I, Life member in Indian Society of Geomatics (ISG), and he was an advisory board member in Kerala Agricultural University-2024. His contributions have earned him multiple awards and commendations from ISRO, NIAS, IIT Kharagpur, Karnataka Forest Department, and Digital University of Kerala.
