What I speak about
I speak to a few hundred students a term and none of it was visible anywhere. This is the record, and it is also what an organiser needs before inviting me.
Sessions
Two of these I have given, on the dates shown. The other three are drafted from what I research and teach, not from a session I have delivered — they are a starting point for a conversation rather than a fixed offer, and the formats are mine to confirm.
Your data, your privacy: understanding digital footprints
What a phone, a search box and a loyalty card actually record, why removing your name from a dataset does not make it anonymous, and what a student can do about it. No mathematics assumed.
RAG, vector databases and semantic search
How retrieval-augmented generation works end to end: embeddings, a vector store, the retrieval step, and where the failures actually come from. Built for faculty who need to teach it next term.
Differential privacy, from the Netflix Prize to the census
The de-anonymisation results that broke the old approach, the guarantee that replaced it, and what it cost when the United States Census adopted it. The lecture version of my doctoral work.
Privacy by design in a machine learning pipeline
Where privacy is won and lost in a real system: collection, training, model release, deployment. Aimed at people who are building something now and have to make these decisions this month.
Responsible AI for engineering students
Fairness, interpretability and accountability as engineering constraints rather than ethics slides — what to measure, and what to do when the measurement comes back badly.
On the record
5 sessions and events. Across the 2 where a headcount was taken, that is 920 people in the room.
Roles I hold
Standing commitments rather than one-off events. These are where most of the sessions above come from.
Inviting me
Tell me the audience, the date and how long you have, and I will tell you within a few days whether I can do it. The work with me page has the form, and the speaking path there lists what I need to know.
For anything outside Coimbatore, say in the first message what you can cover on travel and what the date is fixed to. It saves an exchange of messages later.
Still to come: slides and photographs from the sessions above. I have them, they are not yet gathered in one place.
