The Chain: Protein Engineering Podcast

In this insightful discussion, Sarel Fleishman, a biomolecular sciences professor, dives into structure prediction and the need for robust benchmarking in AI/ML. Max Vasquez, Chief Computing Officer at Adimab, shares how large synthetic antibody libraries can streamline discovery. Arvind Rajpal emphasizes the importance of de novo design for tricky epitopes, while Vincent Ling highlights AI’s broader impacts on productivity within pharmaceutical companies. Together, they explore the challenges and potential of combining traditional methods with cutting-edge technology in biotherapeutic research.

In this episode of The Chain, host Tariq Ghayur, PhD, Tariq Ghayur Consulting, LLC, talks with Pamela Barney, former associate director of HR, AbbVie, about her career within biotech/pharma organizations and some key lessons learned, such as taking advantage of your contacts and network, managing diverse workforces, and HR’s role in creating an engaged team. Barney also discusses why she entered the HR field and the challenges of culture changes when transitioning from a small organization to a large company. AbbVie: https://www.abbvie.com/   

In this episode of The Chain, host Brandon DeKosky, associate professor, speaks with MIT colleague Jessica Stark, Underwood-Prescott career development professor, about glycans and why they are important in cancer research. Stark discusses how she became interested in immunology, what her PhD and post-doctoral training was like, her thoughts on singlets operating as part of a network of checkpoint molecules, and what’s currently going on in glycobiology. She also talks about her keynote presentation at PEGS 2025 and what her new lab is working on. LINKS: MIT Department of Chemical Engineering MIT Department of Biological Engineering MIT 

Andreas Plückthun, a leading biochemist at the University of Zurich, shares insights on the role of AI and machine learning in antibody and protein engineering. He discusses the importance of epitope specificity in drug development and the challenges in accessing and curating high-quality data. The conversation also covers advancements in predictive models and the necessity of experimental validation to enhance therapeutic protein design. Plückthun emphasizes the need for integrating diverse data modalities and improving methodologies to overcome existing hurdles in the field.

February 21, 2025 | This episode marks the 50th anniversary of one of the most influential papers in biomedical science—the 1975 Milstein and Köhler paper on hybridoma technology, which paved the way for monoclonal antibodies. Ralph Minter, Biotech CSO/CTO, discusses this important milestone with a true pioneer in the field, Sir Greg Winter, Nobel Laureate and one of the key figures in the development of therapeutic antibodies. 

In this episode of The Chain, host Andrew Bradbury, CSO of Specifica, an IQVIA business, speaks with Randolph Lopez, CTO and co-founder of A-Alpha Bio, about how A-Alpha Bio is changing the game of protein-protein interactions with their platform AlphaSeq. Lopez delves into the origins, the process, the successes, and the possibilities of the company’s platform and how it can help with epitope mapping, affinity predictions, and off-target binding. With the data the platform generates, Lopez also discusses how this affects the potential of AI and ML. LINKS:    Bionavigen A-Alpha Bio Specifica 

November 12, 2024 | In this episode of The Chain, host Rakesh Dixit, PhD, DABT, president and founder of Bionavigen Oncology and Regio Biosciences, speaks with Anthony Tolcher, M.D., FRCPC, cofounder of NEXT Oncology, about antibody drug conjugates (ADCs) including the role of the bystander effect, approaching targets in oncology, dual-payload technologies, the potency of new payloads, and bispecific targeting. Tolcher also shares what inspired him to pursue oncology, how he came across ADCs, and where he sees ADCs heading in the future.        LINKS:    Bionavigen NEXT Oncology 

October 15, 2024 | In this month’s episode of The Chain, host Rakesh Dixit, PhD, DABT, president and founder of Bionavigen Oncology and Regio Biosciences, and John Lambert, PhD, consultant, about antibody drug conjugates (ADCs) then, now, and beyond. Lambert shares his experiences from his decades-long career at ImmunoGen, why ADCs are more successful now compared to in the past, and where he sees ADCs going forward. He also discusses his thoughts on the half-life of diffusible payloads, the toxicity of the bystander effect, and more.  LINKS:BionavigenImmunoGen 

September 10, 2024 | In this episode of The Chain, host Nimish Gera speaks with Tariq Ghayur, of Tariq Ghayur Consulting, LLC and Entrepreneur in Residence, FairJourney Biologics (and a fellow host of the podcast), about the current renaissance of bispecifics and ADCs, the impact of AI in pharmaceuticals, and what to watch out for in the biopharma space in the next few years. Ghayur also shares his journey from BASF Pharma to AbbVie, what it was like when the industry shifted its focus from small molecules to biologics, and the major differences between doing a postdoc in academia versus in the industry. 

In this episode of The Chain, host Nimish Gera, Ph.D., vice president of biologics at Mythic Therapeutics, speaks with Peyton Greenside, CSO and co-founder of BigHat Biosciences, about the role of AI and machine learning in antibody engineering and targeting complex modalities, including bispecifics and ADCs. Greenside also discusses the work her organization does, what BigHat is doing to ensure the quality of data to train their AI models with, the methods of approaching harder targets such as GPCRs, and certain properties that AI can optimize better.
