The Future of Work
Distinguished lecture — BIM 43 Inauguration & Orientation Programme, Bharathidasan Institute of Management (BIM), Tiruchirappalli
A lecture to the incoming MBA batch on the future of work: the five forces reshaping it, generative AI first among them, and what the PwC, World Economic Forum and Goldman Sachs figures say about jobs, skills and wages. Then how AI products are actually built — the on-device knowledge graph and natural-language search in Gallery, which went from the lab to Galaxy phones, and the agentic AI now following them — and the T-shaped, AI-fluent manager all of this asks for. Followed by Q&A.

9 – 10 May 2026
Machine Translation in Bengali: History, Application & AI Frontier
Resource person, days 3 – 4 of the five-day workshop — Platform Bengali, an arts research project supported by the India Foundation for the Arts, with the Department of English, Ramakrishna Mission Residential College, Narendrapur
Two days for translators, literature students and digital-humanities researchers on how machines came to find meaning across languages. Day 3: the foundations of NLP; cross-lingual retrieval and the Indian CLIA programme; summarisation and question answering; what BLEU, chrF and COMET measure, and why they struggle with Bengali; and a first look at neural representations. Day 4: the four eras of machine translation — rule-based, statistical, machine-learning hybrids, and neural MT with attention and Transformers, IndicTrans among them — with worked Bengali examples. The other days were taught by Prof. Bidyut Baran Chaudhuri (script, OCR and corpora) and Pritam Dey (LLMs and agents).

August – October 2024
Samsung Solve for Tomorrow 2024
Jury member — Solve for Tomorrow, Samsung India's national education and innovation competition for students, run with FITT at IIT Delhi, the Ministry of Electronics & IT and the United Nations in India
Samsung India’s flagship CSR programme asks school students (14 to 17, on “community and inclusion”) and young people (18 to 22, on “environment and sustainability”) to solve a problem they see around them. In 2024 a hundred shortlisted teams went through regional rounds to twenty, then an innovation walk through Samsung’s offices and R&D centres, and on 30 August pitched at the National Pitch Event at IIT Delhi to a jury of Samsung’s own experts and leaders, which chose the ten finalists. I was one of that jury. What I looked for: innovation that serves a community, solutions that use less energy, whether the team had understood the problem its customers actually have, how far it had carried the idea, and how its members worked together. At the Grand Finale in October the ten teams pitched to a grand jury of Samsung and industry leaders; Eco Tech Innovator from Golaghat, Assam, and METAL from Udupi, Karnataka, were named the champions.
