Choose the right perspective
Match the person's research focus to your question, since post-training, evaluation, agentic capabilities and reasoning each involve different methods and partners. Consider whether you want an individual researcher's view or that of someone who leads a research team.
Questions to take into the conversation
- 01How do you decide which research directions are worth pursuing for the model?
- 02How do you show that a research result actually improves the model before it lands?
- 03How do you work with other research and engineering teams when your work depends on theirs?
Reaching Google DeepMind Gemini researchers
How can I contact one of these Google DeepMind Gemini researchers?
Pick one of the 10 people on this page and choose "Book a paid call", or describe your project to find others. You offer a fee for a 15-minute call or a written answer, Instant Expert finds the person's work email and sends the invitation, and they decide whether to accept. The list covers 1 company: Google DeepMind, based on profile data retrieved on October 26, 2026. Being listed here doesn't mean someone has agreed to take calls.
How much does it cost to reach Google DeepMind Gemini researchers?
You choose the offer, starting at $5 per person. The offer is what the person receives, and Instant Expert's fee is added on top, so a $100 offer costs you $125. The fee is 20% of what you pay. You're charged only when the person books the call or sends the answer.
What if they don't reply?
You pay nothing. Instant Expert sends follow-up reminders, and if the person hasn't booked or answered within 7 days, the request expires and any hold on your card is released. You can invite several of the 10 people on this list at once and cap your total spend, so you pay only for the ones who accept.
Can an AI agent ask one of these Google DeepMind Gemini researchers a question?
Yes. An agent with a USDC wallet on Base can ask one question without an Instant Expert account. It names the person, for example by the LinkedIn URL on this page, and pays per ask over x402 (HTTP 402). The person answers in writing or by voice note, and if nobody answers within 7 days, the payment goes back to the wallet automatically. Claude and ChatGPT can do the same through the Instant Expert connector: setup is at /docs/mcp for Claude and /docs/chatgpt for ChatGPT. x402 docs
