NEW YORK (Aug. 24, 2026)—Embracing the transformational potential of new molecular profiling and artificial-intelligence-based data processing technologies on clinical and scientific innovation, Weill Cornell Medicine has created a new research department, the Department of Systems and Computational Biomedicine. Dr. Dan Landau, an internationally recognized cancer researcher and geneticist whose pioneering advances include single-cell-profiling technology innovation and an artificial intelligence-powered liquid biopsy for detecting tumor DNA in blood, will serve as the department’s inaugural chair, effective Sept. 1.

The Department of Systems and Computational Biomedicine consolidates elements of the existing Department of Physiology and Biophysics, the Institute for Computational Biomedicine, and other computation-centered and systems biology faculty and facilities. Its establishment reflects a multiyear initiative to realign and optimize the organization of basic and translational science to facilitate interdisciplinary research and promote mentorship of faculty at all levels.

Prostate Cancer Hijacks Amino Acid Metabolism to Signal Hormone Therapy Resistance

Prostate tumors can rewire amino acid metabolism to override the normal brakes on cholesterol production, a process that may fuel hormone therapy resistance, according to a study by Weill Cornell Medicine investigators.

The preclinical study, published Aug. 20 in Nature Metabolism, revealed that a compound called propionyl-CoA, produced by the breakdown of amino acids isoleucine and valine during normal energy metabolism, acts as a signal that switches on cholesterol production. This helps prostate cancer cells adapt to the hormone-deprived conditions resulting from treatment and acquire more aggressive features.

By revealing this previously unrecognized connection, the study identified a potential weakness in prostate cancer that could be targeted with new drugs or, pending clinical testing, dietary strategies that reduce levels of isoleucine and valine. These essential amino acids are abundant in protein-rich foods such as meat, fish and dairy products.

When Kiran Abraham-Aggarwal started his undergraduate studies at Cornell’s School of Industrial and Labor Relations (ILR), he assumed it would lead to a career in economic development or perhaps law, like many of his classmates. With an interest in advocacy and policy reform, these disciplines felt like a fit. But then, in his sophomore year, he attended his parents’ class reunion at Weill Cornell Medical College in New York City. Included on the schedule was a tour of the anatomy lab and an opportunity to view a cadaver—a person affected by black lung disease. Abraham-Aggarwal studied the condition in one of his ILR classes, learning about coal miners in West Virginia, but seeing it up close changed his whole perspective.
