Talking Points

Recent interactions between the hosts and their guests.

These 30-something Harvard Professors are making biology programmable - AbuGoot Lab
Q: How do virtual cells and world models accelerate drug development and consumer health products?
By embedding multi-omics and behavioral data into AI-driven models, we can run in silico screens and virtual trials to compress timelines, prioritize interventions, and reveal new product opportunities in both pharma and consumer wellness spaces.
These 30-something Harvard Professors are making biology programmable - AbuGoot Lab
Q: Why is aging discussed as a target for intervention, and how do you frame its measurement?
Aging is a systems-level driver of many diseases; we measure it with a panel of biomarkers, including proteomics and epigenetic clocks, and focus on readouts that reflect functional health like sleep, muscle, and cognitive performance to guide trials.
These 30-something Harvard Professors are making biology programmable - AbuGoot Lab
Q: What does it mean to program biology like a computer, and how does that guide your lab work?
It means designing biological systems with reproducible, predictable models and leveraging data and AI to simulate and optimize outcomes across molecular to human scales, enabling faster development of interventions.
Ex-BCG leader & David Sinclair’s COO on why evolution selected for aging, and how to get big pharma to invest into longevity therapies - Michael Ringel
Q: What is the core argument in Ringel's Why We Age paper and how does it relate to potential interventions?
The paper argues aging results from evolutionary optimization, not a fixed inevitability, and that aging is a regulated, malleable process. This framework supports pursuing interventions that tap into the regulatory networks (like nutrient-sensing and epigenetic mechanisms) to influence lifespan and healthspan.
Longevity politics with the Forbes 30U30 lobbyist changing DC - Dylan Livingston, A4LI
Q: How has congressional engagement evolved since you started, and what makes a legislator care about longevity?
Legislators are broadly supportive, but the key is follow-up and scale: building a network of advocates across districts, running a bipartisan caucus, and showing tangible outputs like funding and bills. Messaging that ties longevity to fiscal savings and military readiness helps cross partisan lines.
