Hello๐Ÿ‘‹ I am

Koushik Deb โ€” AI Engineer, Researcher & Author

|

I'm an AI engineer at Accenture, building Generative-AI and Agentic-AI systems, and a PhD researcher at IIIT Kalyani studying how large language models behave across English, Hindi & Bengali. My work spans NLP, LLM evaluation and multilingual AI, and I'm the author of Keep It Simple: AI for Teachers.

What I'm working on now

Current Focus in AI & Research

Generative AI

Designing and shipping GenAI solutions for healthcare clients at Accenture, from the first use-case proposal through proof of concept to a deployed product.

Agentic AI

Systems that pair a language model with tools and retrieval (RAG), so answers come from a client's own documents and the work can run in production.

Large Language Models

Measuring how commercial LLMs respond to biased framing in a prompt. The latest study covered six models and 683,616 responses.

Multilingual AI & LLM Bias

Doctoral research at IIIT Kalyani into whether a model's fairness survives translation, tested in English, Hindi and Bengali.

Natural Language Processing

Sentiment analysis, topic modelling and threat detection in social-media text, plus a granted patent for running several NLP tasks offline on one device.

AI Evaluation

Deciding whether a model is fit for a particular job before anyone relies on it, with repeatable tests in research and practical checks at work.

The book

Keep It Simple: AI for Teachers

A practical guide helping teachers and education professionals understand and use AI โ€” which tool to reach for, what to ask it, and what to check before anything reaches students. Published September 2026.

About Koushik Deb

Koushik Deb โ€” professional portrait
๐Ÿง  GenAI & Agentic AI
๐ŸŒ EN ยท HI ยท BN

I wear two hats. By profession I am an AI Engineer and Tech Lead at Accenture, where I design and ship Generative-AI and Agentic-AI solutions for global healthcare clients โ€” proposing new use-cases, building POCs and turning them into deployed products.

In parallel, I am a part-time PhD candidate at IIIT Kalyani (final year), researching bias detection and mitigation in multilingual large language models across English, Hindi and Bengali โ€” how prompts manipulate models, and how to measure and reduce that vulnerability.

Across 13+ years at Accenture, Cognizant, IBM and Capgemini I have built software for Apple, IKEA, Cigna, Roche, Tiffany & Co. and Sanofi. Along the way I picked up three granted patents โ€” from offline NLP on devices to drone-augmented pest control โ€” and a habit of tinkering with ESP32 boards and smart-agriculture hardware on weekends.
