Hello, I’m
Neil Theise, M.D.

Neil Theise, M.D. is a diagnostic liver pathologist and adult stem cell researcher in New York City, where he is Professor of Pathology and of Medicine at the Beth Israel Medical Center of Albert Einstein College of Medicine. His research revised understandings of human liver microanatomy which, in turn, led directly to identification of possible liver stem cell niches and the marrow-to-liver regeneration pathway. He is considered a pioneer of multi-organ adult stem cell plasticity and has published on that topic in Science, Nature, and Cell.

While continuing laboratory and clinical research, he has extended his work to areas of theoretical biology and complexity theory, defining a "post-modern biology." These ideas suggest that alternate models of the body, other than cell doctrine, may be necessary to understand non-Western approaches to the body and health. Current laboratory investigations focus on nerve-stem cell interactions in human livers, melatonin-related physiology of human liver stem cell and regenerative processes, and aspects of human liver stem cell activation in acute, fulminant hepatic failure.



Science as Koan

When I first began to meditate, I considered the Buddhist approach to things to be completely separate from the scientific. But over time, that changed. At the beginning of my practice, I associated spirituality with transcendence. Eventually, though, I realized that meditation was about being right up against things, in an intimate way. This was a surprise; suddenly, both my scientific work and my Zen practice were aiming at the same sort of inquiry. That realization has propelled a lot of the stem cell research I've done in the last few years. When I ask, What is this body? What is its function? What are its limits? I am asking the same questions in my scientific work that I am in my sitting practice.
