- Dr. Michael Levin is a developmental and synthetic biologist at Tufts University, where he is the Vannevar Bush Distinguished Professor and director of the Allen Discovery Center and Tufts Center for Regenerative and Developmental Biology.
In this episode we talk about Mike’s research, which ranges from studying the molecular biology of cancer, to the bioelectrics of limb regeneration, to memory and higher-order cognition. Mike describes the overall theme of his research as understanding the embodied nature of cognition in organic and synthetic systems, and the philosophical implications of this worldview. We discuss a wide variety of topics ranging from the neurobiology of planarian flatworms, to the future of regenerative medicine, to philosophical questions about the definitions of life, consciousness, and artificial intelligence.

Michael Levin demonstrates patience and presence of mind to rival a Tibetan monk.
Fundamental questions seem to me to be where do the original limited range of body plans come from and why?
New to the podcast you are on to something. Keep em coming.
I've been listening to this podcast for a few weeks now, and it's super interesting. Thank you!
Excellent interview of a brilliant man speaking about a fascinating subject. Love it!🙌🏽
Such an interesting interview, with great questions asked by the interviewer as well!
Aside from the worderful Technical Information, I like the Drums in the corner, reminds me of stories of Richard Feynman and his drums.
I just wonder how much human development relies on sequences of events. Like teeth growing in sequence, or other parts needing a long series of prerequisites. How might that complicate potential regenerative medicine if someone needed something small repaired as good as new, but the body might need to rebuild a much larger region from scratch?
YESSS!!!
