Ho-Juhn Song
Ho-Juhn Song is the co-founder and CEO of PineTree Therapeutics, a Cambridge, Massachusetts biotech building next-generation targeted protein degraders to overcome drug resistance in cancer. A geneticist by training with a Ph.D. from Oregon State University and a former project team leader at the Novartis Institutes for BioMedical Research, Song founded PineTree in 2019 around the AbReptor platform, which degrades membrane-bound and extracellular proteins that conventional drugs struggle to reach. Under his leadership the company licensed its lead EGFR degrader to AstraZeneca in a deal worth more than $500 million in potential milestones and closed an oversubscribed $47 million Series B in October 2025.
Lan Huang
Lan Huang is a chemist turned biotech entrepreneur and the Co-Founder, Chairman and CEO of SEED Therapeutics, a New York clinical-stage company designing molecular glues that direct the cell's own disposal machinery to break down disease-driving proteins once considered undruggable. She earlier founded BeyondSpring Pharmaceuticals and took it public on NASDAQ. A UC Berkeley PhD who solved an early E3 ubiquitin ligase structure, she built SEED around targeted protein degradation with collaborators including Nobel laureate Avram Hershko, and secured partnerships with Eli Lilly and Eisai.
Nan Ji
Nan Ji is co-founder, president and CEO of PAQ Therapeutics, a Burlington, Massachusetts clinical-stage biotech pioneering autophagosome-tethering compounds (ATTECs) to degrade KRAS and other 'undruggable' disease drivers. A Harvard-trained organic chemist with 30+ patent applications, he spent seven years at Novartis, helped build Kymera Therapeutics from seed stage as VP of Chemistry, and launched PAQ in 2020 to hijack the body's natural cellular clean-up machinery for cancer and neurodegenerative disease.
Jesse Chen
Jesse Chen is the founder, president and CEO of Fortitude Biomedicines, a Waltham, Massachusetts biopharmaceutical company that launched in January 2026 with $13 million in seed financing. A serial biotech entrepreneur with an MIT PhD in biological chemistry, Chen previously co-founded TRIANA Biomedicines and Avilar Therapeutics, was the founding scientific hire at Kymera Therapeutics where he built its targeted protein degradation platform, and held discovery roles at Moderna and Millennium Pharmaceuticals. At Fortitude he is betting that molecular glue payloads, packaged into a platform he calls GLUE-DAC, can overcome the drug resistance that limits today's antibody-drug conjugates and extend them into autoimmune disease.
Phil Chamberlain
Phil Chamberlain is the co-founder, president and CEO of Neomorph, a San Diego biotech building molecular glue degraders to drug proteins long written off as untouchable. An Oxford-trained structural biologist, he spent a decade at Celgene and Bristol Myers Squibb decoding how thalidomide works at the atomic level, then turned that science into a company that has signed partnerships with AbbVie, Biogen and Novo Nordisk worth billions and pushed its lead degrader into the clinic.
Arthur T. Sands
Arthur T. Sands, M.D., Ph.D., is the President and CEO of Nurix Therapeutics, a clinical-stage biopharmaceutical company pioneering targeted protein degradation medicines. A co-founder of Lexicon Pharmaceuticals in 1995, he spent 19 years transforming that company from a research startup into a drug-development enterprise generating over $450 million in revenue. At Nurix, he leads efforts to deploy a proprietary DEL-AI platform - combining DNA-encoded libraries with machine learning - to discover and develop small-molecule degraders and degrader-antibody conjugates for cancer and inflammatory diseases. The company's lead asset, bexobrutideg (a BTK degrader), entered pivotal Phase 2 development in 2025 with an 83% objective response rate in relapsed CLL patients.
Jennifer Cygan
Jennifer Cygan is a seasoned biotech executive and Chief Business Officer at EpiBiologics, where she helps advance a pipeline of novel bispecific antibodies designed to selectively degrade extracellular protein targets in oncology and immunology. With a Ph.D. from Harvard and over two decades of business leadership in biotechnology, she has been a pivotal force at Genentech, Calico Life Sciences (managing a $2.5B AbbVie alliance), and has co-founded and served as CBO for multiple emerging biotech companies including Broadwing Bio, Eikon Therapeutics, GenEdit, and Plexium. Her career sits at the intersection of science and strategy - translating cutting-edge biology into deals, partnerships, and companies that matter.
Jorge Dimartino
Jorge F. DiMartino, M.D., Ph.D., is Chief Medical Officer and Executive Vice President of Clinical and Translational Development at Plexium, a San Diego-based biotech pioneering targeted protein degradation. A physician-scientist trained in genetics, immunology, and pediatric oncology across UC Berkeley, Cornell, UC San Diego, and Stanford, DiMartino has spent over two decades advancing cancer drugs from bench to bedside. His fingerprints are on three now-marketed therapies: vismodegib, venetoclax, and enasidenib - each a breakthrough in its own right. At Plexium, he oversees clinical programs targeting SMARCA2, IKZF2, CDK2, and CRAF using the company's DELTA Discovery platform, a novel approach to degrading proteins previously considered undruggable.
Sofia Touami
Sofia Touami, Ph.D., is the Chief Business Officer of Lycia Therapeutics, a South San Francisco biotech pioneering lysosomal targeting chimeras (LYTACs) - a platform invented by Nobel laureate Carolyn Bertozzi to degrade disease-causing extracellular proteins. A trained organic chemist who earned her Ph.D. at Stanford and did postdoctoral work at The Scripps Research Institute, Touami has built a career as one of biotech's sharpest dealmakers, having orchestrated major transactions including Frontier Medicines' landmark global collaboration with AbbVie before joining Lycia in July 2023. She helped close Lycia's oversubscribed $106.6 million Series C in May 2024, positioning the company to bring its LYTAC-based autoimmune therapies into clinical trials.
Chris Varma
Chris Varma, Ph.D., is Co-Founder, Chairman, and CEO of Frontier Medicines, a clinical-stage biotech attacking cancer's 'undruggable' proteins using chemoproteomics, covalent chemistry, and machine learning. A serial biotech founder with 20+ years in life sciences, he previously co-founded Blueprint Medicines (acquired by Sanofi for $9B+ in 2025) and Warp Drive Bio (acquired by Revolution Medicines in 2018), and held investor roles at Third Rock Ventures, Flagship Pioneering, and MPM Capital. His career spans the FDA, Novartis, and three successful company builds - with Frontier Medicines now advancing FMC-376, a first-in-class dual KRAS G12C inhibitor, through Phase 1/2 clinical trials.
