Dr. Atanu Dey is an Assistant Professor in the Information Systems area at the Indian Institute of Management Sambalpur. He completed both his MS and PhD from the Indian Institute of Technology (IIT) Kharagpur. He brings a blend of academic insight and industry experience, shaped through nearly nine years in the technology sector. Prior to joining IIM Sambalpur, he spent around seven years at HP Inc., where he progressed into the role of "Expert Data Scientist IV". In this capacity, he led data-driven initiatives, collaborated across multidisciplinary teams, and worked closely on translating analytical capabilities into strategic business outcomes.
His technical expertise spans Natural Language Processing (NLP), Sentiment Analysis, Data Science, Machine Learning (ML), and Deep Learning (DL). He has been involved in impactful research-oriented initiatives, including contributing to the development of a UKIERI-SPARC Project proposal. The long-term objective of this project was to create algorithms, tools, and dashboards to support organizations and governments in mitigating the environmental impact of electronic waste and fostering a more circular and sustainable economy. This experience reflects his commitment to applying advanced analytics for societal benefit.
Dr. Dey has published some research articles in the areas of NLP, ML, DL and Information Systems, focusing on how intelligent technologies can extract meaningful insights from unstructured data and support better decision-making. He continues to build on this intersection of research and practice, aspiring to contribute to the academic community, mentor emerging scholars, and engage with industry partners to advance data-driven innovation.
