In this episode of Precision Signals, Sean Khozin speaks with Dan McHugh, investor at Yosemite, about the systems that mediate between scientific discovery and patient impact. Dan’s path runs from Stanford bioengineering and the Greenleaf Lab to Bain & Company, Emerson Collective, and the co-founding of Tune Therapeutics. Across these roles, he has operated at the boundary between deep biological science and the capital and policy structures that determine whether that science ultimately reaches patients.

The conversation examines how incentives, reimbursement, and regulation shape the fate of cancer therapies, sometimes in rather unpredictable ways. It also explores Yosemite’s founding by Reed Jobs, Dan’s longstanding friendship with him, and how trust, time horizon, and shared mission have shaped a hybrid model that combines venture investment with grant-based risk-taking.

This is a discussion about cancer, but it is equally a discussion about architecture: how systems are designed and what they reward.

Dr. Karen Knudsen, CEO of the Parker Institute for Cancer Immunotherapy (PICI), joins Dr. Sean Khozin to dissect the science and business of curing cancer. From her upbringing as a self-described "nomad" and "army brat" to leading the American Cancer Society, Karen shares her journey from the lab bench to the boardroom.

In this episode, we explore the Parker Institute's unique model of "venture philanthropy." Karen explains how PICI uses shared intellectual property to de-risk early-stage science and spin out venture-ready companies like Dispatch and Orbital Therapeutics. We also discuss the challenges of modernizing a historic non-profit with "no product" to sell , the intersection of AI and biomarkers with companies like ArteraAI , and PICI's massive data project, "Radiohead".

Karen is candid about her leadership philosophy: she is not a "keep the trains running" executive, but a leader built for transformation.

In Episode 4 of Precision Signals, Dr. Sean Khozin sits down with Daniel Arbess—investor, social entrepreneur, and healthcare innovator—to explore why the limiting factor in solving cancer and neurodegenerative diseases isn't breakthrough science, but institutional innovation.

Daniel Arbess has built a career on questioning foundational assumptions across multiple domains: from analyzing Cold War nuclear policy to restructuring post-Soviet industries as the youngest-ever partner at White & Case, to founding Xerion Capital, a hedge fund that delivered over 25% annualized returns through the 2008 financial crisis. Now, he's applying that same lens to healthcare transformation.
