Brief Bio & Research Interests

 

Amitava Presently, since July 2022 I am working as a Research Associate Professor at the Artificial Intelligence Institute (AIISC), University of South Carolina, USA. Previously, I spend 3+ year Wipro Labs, in Bangalore, India. I maintain my association with Wipro Labs in the capacity of an Advisory Scientist. During my tenure at Wipro, I initiated and led multiple academic partnerships, including collaborations with institutions such as IIT Patna, IIIT Delhi, IIIT Hyderabad, UT Austin, and the AI institute at the University of South Carolina. I have started a joint PhD program, a unique setup for industry practitioners to earn their doctoral degrees while working full time in industry. I am also currently advising Shaip on biomedical NLP. I am an adjunct faculty at AI-NLP-ML group of Indian Institute of Technology Patna (IIT Patna).

Earlier I spent a stint (a semester) as an Associate Professor in the department of Computer Science & Engineering at Mahindra University, Hyderabad. Mahindra University is an Indo-French collaborative institute – a collaboration between Tech Mahinda, and Centrale Supélec, France. Before that, I worked at the Indian Institute of Information Technology (IIIT) Sri City, Andhra Pradesh, India during June 2015-June 2018 as an Assistant Professor in the Computer Science department. During July 2017- July 2018 I had the privilege of being affiliated associated with Indian School of Business (ISB), Hyderabad as a Visiting Scientist at the Srini Raju Centre for IT and The Networked Economy (SRITNE).

I have experienced two academic postdocs: in Europe and in the USA. In the USA I worked as a Research Scientist in the Human Language Technologies (HiLT) lab at the University of North Texas, USA. During summer 2014 I worked at James Pennebaker’s lab, the University of Texas-Austin as an Invited Researcher. I spent one year working as a European Research Consortium for Informatics and Mathematics (ERCIM) Post-Doctoral Fellow at the Norwegian University of Science and Technology (NTNU), Norway during 2012-2013. Before moving to UNT I did work very briefly with Samsung Research India, Bangalore during the first half of 2013 as a Chief Engineer.

I have obtained Ph.D. (Engineering) from Jadavpur University, India. During my doctoral study, I worked closely for an Indo-Japan collaborative project entitled “Sentiment Analysis where AI meets Psychology” with the Tokyo Institute of Technology, Japan.

Completed the supervision of three Ph.D. candidates who currently hold positions as Assistant Professors at the National Institute of Technology (NIT), guided the research of two M.S. students, and provided mentorship to numerous undergraduate students. Over the years worked with numerous interns, have successfully gained admission to various top-tier universities globally.

Research Interests – NLP + Social Computing + Multimodal AI + Constitutional AI



My research interests broadly span over three areas and more specifically their intersection: human language, cognition/mind, and artificial intelligence, particularly within the realm of Natural Language Processing (NLP). Throughout my doctoral studies, my primary research focus revolved around Sentiment Analysis and Opinion Mining from textual data. For the past 19+ years, I have been deeply engaged in the field of language technologies, and my contributions have yielded a substantial body of work (over 120+ papers, H-index 33+) that spans a diverse spectrum of subjects. In recent years, my endeavors have shifted towards the domains of social computing and multimodal AI, including the intricate challenges of multimodal misinformation and disinformation. I am exploring the utilization of physics-inspired neural networks to foster a new generation of language models - EUROPA and EARENDEL. These initiatives involve infusing concepts from Gravitational Wave theory into neural networks and AI. Currently, my focal point lies in the domain of CIVILIZING AI / CONSTITUTIONAL AI. This involves proactive measures for hallucination mitigation and managing other associated risks
