S6E07: Foundation Models and Agents
In our season six finale, we dive deeper into how artificial intelligence (AI) is shaping the future of drug discovery and scientific research. With remarkable scale and speed, AI models parse through complex datasets and confirm or generate hypotheses, which can help scientists accelerate R&D. In this episode, co-host Danielle Mandikian welcomes Aviv Regev, Head of gRED, and Jure Leskovec, Professor of Computer Science at Stanford University, to talk about foundation models and autonomous agents. Together, they explore the opportunities and challenges of applying AI in drug discovery, including balancing innovation with scientific rigor and the evolving role of scientists. They also discuss how AI is reshaping the future of research — from building more biologically meaningful models to advancing agent-based systems and lab automation.

S6E06: Decoding Lung Disease
From our first breath, the air we breathe and our genes shape how our lungs function. It’s a complex interplay we began exploring in our season four episode “Take A Deep Breath: Treating Asthma.” Today, we’re branching out to discuss lung biology and the diseases that make it difficult to breathe. In this episode, co-host Maria Wilson speaks with Dorothy Cheung, Executive Group Medical Director, and Daniel Lafkas, Senior Principal Scientist, Translational Discovery Research, Roche, to understand how conditions with unmet need like chronic bronchitis and emphysema disrupt lung function. They discuss the challenges to treating lung diseases and explore promising approaches, from cutting-edge imaging technologies that help researchers uncover early drivers of disease, to treatments aimed at stopping the loss of lung function and restoring it.

S6E05: Cells at Work
Cell therapy holds immense potential to transform the way we treat conditions in oncology, ophthalmology, autoimmune disorders, and a wide range of other therapeutic areas. But how do these engineered cells work, and how do scientists ensure they are safe and function as intended? In this episode, co-host Danielle Mandikian sits down with Todd McDevitt, Head of Cell Therapy, to discuss how cell therapies operate within the body, the challenges researchers face in this field, and the advancements needed to unlock their full potential for patients.

S6E04: The Power of Digital Twins
Digital twins are virtual models of real-world systems that have been gaining momentum as a powerful tool in drug discovery and development. We touched on this concept last season when we covered computational advancements in drug discovery. Now, we’re taking a deeper dive into the power of digital twins. By leveraging genomics, physical health data, lab results, and other clinical datasets, digital twins allow researchers to model certain diseases, help predict treatment outcomes, and more efficiently optimize dosing strategies for clinical studies. In this episode, co-host Maria Wilson is joined by Iraj Hosseini, Distinguished Scientist and Director, gRED Development Sciences, to explore how digital twins could simulate thousands of "what if" scenarios, paving the way for faster and more patient-centric therapeutic strategies.

S6E02: AI and the Quest for New Antibiotics
We published our first episode on the threat of antibiotic resistance in 2016, and nearly a decade later, it remains one of the world’s most pressing health crises. Today, with advances in artificial intelligence (AI), the race to develop new antibiotics is evolving. In this episode, co-host Danielle Mandikian sits down with guests Tommaso Biancalani, Distinguished Scientist and Director of Biological Research and AI Development, and Steven Rutherford, Senior Principal Scientist and Director of Infectious Diseases in Research Biology, to share the latest in the fight against antibiotic resistance. Together, they discuss the challenges of antibiotic discovery and development, and how AI could streamline the process of identifying novel antibiotics within the vast, uncharted chemical universe.

S6E01: Digging Deeper into Obesity
As we kick off season six, we’re diving deeper into one of our most popular topics from last season – our evolving understanding of obesity. In this episode, co-host Maria Wilson unpacks the latest in obesity biology and management with Manu Chakravarthy, Senior Vice President and Global Head of Cardiovascular, Renal and Metabolism Product Development, who discusses the stigma associated with obesity and how thousands of years of human evolution contribute to this chronic condition. While lifestyle, diet and exercise modifications are still essential in addressing the biological factors that drive obesity, they explore how emerging treatments have the potential to rewire the brain’s hunger and satiety signals – offering a more personalized, sustainable approach.
