In this episode, we welcome Dr. Ian Chronis, a recent Ph.D. graduate preparing to begin his postdoctoral work at the University of Michigan. Host Yamina Berchiche sets a welcoming tone as they dive into Ian’s unique academic journey—from early interests in medicine to his pivot toward pharmacology and GPCR research. His story offers valuable insights for anyone navigating the path from student to scientist.
Ian discusses how his experiences at the University of Chicago and the University of Michigan shaped his scientific curiosity, particularly around G protein-coupled receptors (GPCRs). His research centers on the beta-2 adrenergic receptor and GPR65, a proton-sensing receptor with promising implications in cancer biology.
He shares fascinating findings from his work on GPR65, highlighting its unusual constitutive internalization and its ability to signal from acidic endosomes. This dual functionality—environmental sensing and compartment-specific signaling—offers a new layer of complexity in GPCR behavior. Yamina underscores the therapeutic potential of GPR65, especially in the context of cancer immunotherapy, and how understanding receptor activity in acidic microenvironments could unlock new therapeutic strategies.
Throughout the episode, Ian reflects on the value of a supportive lab culture, the need for better experimental tools in GPCR signaling, and the importance of engaging with the broader GPCR research community to drive innovation. The conversation wraps with a playful exchange about possible podcast titles, with Yamina suggesting "Ancient Greek Chemistry and GPCRs"—a nod to Ian’s heritage and the wide-ranging themes covered.
This episode is both educational and inspiring, offering a behind-the-scenes look at a rising scientist’s journey in the ever-evolving world of GPCR research.

About Ian Chronis
I recently finished my PhD in the lab of Dr. Manoj Puthenveedu at the University of Michigan, where I am now working as a postdoc. My research has looked at the trafficking and signaling of adrenergic and proton-sensing receptors, with specific focus on identifying novel regulatory proteins governing their function.
