In this episode, Nathan sits down with Tanishq Mathew Abraham, 19-year-old UC Davis grad and one of the youngest people in the world to receive a Ph.D, with a degree in biomedical engineering. Tanishq is the founder of the Medical AI Research Center (MedARC), and with his teammates, recently published a paper: Reconstructions of the Mind's Eye, which encompasses their breakthrough research on reconstructing visual perceptions from fMRI scans into images. In this episode, Nathan and Tanishq talk about the technology behind the fMRI-to-image project, developing the model, and future applications for this research.

Part 2 with Tanishq will be released as the next episode.

We're hiring across the board at Turpentine and for Erik's personal team on other projects he's incubating. He's hiring a Chief of Staff, EA, Head of Special Projects, Investment Associate, and more. For a list of JDs, check out: eriktorenberg.com.

RECOMMENDED PODCAST:

The HR industry is at a crossroads. What will it take to construct the next generation of incredible businesses – and where can people leaders have the most business impact? Hosts Nolan Church and Kelli Dragovich have been through it all, the highs and the lows – IPOs, layoffs, executive turnover, board meetings, culture changes, and more. With a lineup of industry vets and experts, Nolan and Kelli break down the nitty-gritty details, trade offs, and dynamics of constructing high performing companies. Through unfiltered conversations that can only happen between seasoned practitioners, Kelli and Nolan dive deep into the kind of leadership-level strategy that often happens behind closed doors. Check out the first episode with the architect of Netflix’s culture deck Patty McCord.
