Robert Tjian, PhD

Dr. Tjian joined The Column Group as a Discovery Partner in September 2016. Prior to that he served as President of the Howard Hughes Medical Institute 2009-2016.

Dr. Tjian discovered the first human proteins called transcription factors that bind to specific sections of DNA and play a critical role in regulating how genetic information is expressed into the thousands of biomolecules that keep cells, tissues, and organisms alive. Tjian’s laboratory has focused on disruptions in the process of transcription that cause diseases such as cancer, metabolic syndromes, and neuro-degenerative diseases. Most recently, he has developed cutting edge molecular imaging systems to track the dynamic movement of individual proteins in live cells in real time to study how transcription factors control the self renewal, pluripotency and differentiation of embryonic stem cells.

Dr. Tjian joined the University of California, Berkeley faculty in 1979, where he assumed several leadership roles such as: Director of the Berkeley Stem Cell Center, Faculty Director of the Li Ka Shing Center for Biomedical and Health Sciences and Head of the Siebel Stem Initiative. He currently holds the Li Ka Shing Chancellor’s Chair in Biology and serves as scientific advisor to the Chan Zuckerberg Initiative and the BioHub.

He is a member of the National Academy of Sciences and has received numerous awards including the Alfred P. Sloan Prize and the Louisa Gross Horwitz Prize. He was a co-founder of Tularik with Dave Goeddel and Steve McKnight and a founding Science Partner of TCG.

Science Partner

Charles Sawyers, MD

Charles Sawyers, MD, is an Investigator of the Howard Hughes Medical Institute and the inaugural Director of the Human Oncology and Pathogenesis Program (HOPP) at Memorial Sloan-Kettering Cancer Center. His laboratory is currently focused on characterizing signal transduction pathway abnormalities in prostate cancer, with an eye toward translational implications. His earlier research focused on BCR-ABL tyrosine kinase function in chronic myeloid leukemia. This work, and that of colleagues Brian Druker and Novartis, led to the development of the kinase inhibitor imatinib (Gleevec) as primary therapy for chronic myelogenous leukemia (CML), and the discovery that imatinib resistance is caused by BCR-ABL kinase domain mutations. This discovery led him to evaluate second generation Abl kinase inhibitors, such as the dual Src/Abl inhibitor dasatinib, which received fast-track approval at the FDA in June 2006. Dr. Sawyer’s more recent work in prostate cancer has defined critical signaling pathways for disease initiation and progression through studies in mouse models and human tissues. This preclinical work led to the development of a novel anti-androgen ARN-509, a small-molecule inhibitor discovered in collaboration with UCLA chemist Michael Jung, which targets the increased levels of androgen receptor found in hormone-refractory disease.

Dr. Sawyers is past President of the American Society of Clinical Investigation and served on the National Cancer Institute’s Board of Scientific Councilors. He has won numerous honors and awards, including the Richard and Hinda Rosenthal Foundation Award, the Dorothy Landon Prize from the American Association of Cancer Research, the David A. Karnofsky Award from the American Society of Clinical Oncology, and the 2009 Lasker-DeBakey Clinical Medical Research Award. He is a member of the Institute of Medicine and in 2010 was elected to the National Academy of Sciences.

Dr. Sawyers was a co-founder of Aragon Pharmaceuticals and the founder of Seragon Pharmaceuticals. He is also the founder of ORIC Pharmaceuticals.

Huda Y. Zoghbi, MD

Dr. Huda Y. Zoghbi is a professor in the Departments of Pediatrics, Molecular and Human Genetics, Neurology and Neuroscience at Baylor College of Medicine. She is also an investigator at the Howard Hughes Medical Institute and the director of the Jan and Dan Duncan Neurological Research Institute (NRI) at Texas Children’s Hospital. At HHMI, Dr. Zoghbi and her collaborators have unraveled the genetic underpinnings of a number of devastating neurological disorders, including Rett syndrome and spinocerebellar ataxia type 1 (SCA1). Their discoveries have provided new ways of thinking about more common neurological disorders, including autism, intellectual disability, and Parkinson’s disease, and could lead to better treatments. Dr. Zoghbi and her colleagues have also identified the mutation responsible for SCA1, one of several polyglutamine neurodegenerative disorders that slowly rob their victims of balance and motor control. Her lab team is searching for compounds that enhance the clearance of mutant proteins in several of these diseases, which might slow disease progression or prevent it altogether.

Helen Hobbs, PhD

Dr. Hobbs is a human geneticist with expertise in lipid metabolism. She is an Investigator of the Howard Hughes Medical Institute and a Professor of Internal Medicine and Molecular Genetics at the University of Texas Southwestern Medical Center. She spearheaded the establishment of the Dallas Heart Study (DHS), a multiethnic, population-based study in which she and her scientific partner, Jonathan Cohen, have discovered multiple genetic determinants of plasma lipid levels and cardiovascular risk. They identified the first individuals with inactivating mutations in PCSK9 and showed that these individuals have reduced blood levels of low density lipoprotein (LDL)-cholesterol and are protected from heart disease. These findings led to the rapid development of two FDA-approved, anti-PCSK9 antibodies for treatment of hypercholesterolemia and prevention of heart attacks. Her work has highlighted the function of selected angiopoietin-like (ANGPTL) family members in lowering plasma lipid levels and altering lipid trafficking to tissues. She also identified and has characterized the function of a heterodimeric cholesterol transporter (ABCG5/ABCG8) that protects humans from the accumulation of dietary sterols.

More recently, the focus of her work has been on fatty liver disease. Here she has discovered genetic variants conferring susceptibility to fatty liver disease (PNPLA3, TM6SF2) and resistance (HSD17B13) to progression of the disorder; she is currently determining the physiological and pathological roles of these proteins.

She was elected to the National Academy of Medicine (2004) and to the National Academy of Sciences (2007). Among her awards, she has received the Breakthrough Prize in Life Sciences (2015), the Grand Prix Award from the Institute of France (2018), and the Harrington Prize for Innovation and Medicine (2018). Dr. Hobbs is on the Board of Directors at Pfizer, Inc.
