M. Marc Abreu, MD
Medical Doctor, Physicist, and Ophthalmologist
Former Faculty, Harvard University
Dr. M. Marc Abreu is a pioneering medical scientist renowned for his groundbreaking work in brain thermodynamics and its applications in treating cancer and neurological disorders. His extensive academic background includes studies in medicine and physics, along with specialized training and postdoctoral research at Indiana University, University of Pittsburgh, Harvard, and Yale.
As a former faculty member at both Harvard and Yale Medical Schools, Dr. Abreu has made significant contributions to medical education, research, and patient care. His most notable discovery at Yale—the Brain-Eyelid Thermal Tunnel (BTT)—enabled the first-ever continuous, non-invasive monitoring of human brain temperature, leading to multiple patents and FDA-approved technologies.
He developed the first computer system cleared by the FDA for temperature monitoring during critical medical procedures, improving patient safety. Additionally, he was the first to identify the radiation signature of glucose, earning U.S. Patent #7403805. His BTT technology was recognized by the U.S. Federal Government with a Therapeutic Discovery Project Grant, a program designed to support medical innovations with the potential to revolutionize cancer treatment and contribute to finding a cure within the next 30 years.
Dr. Abreu has collaborated with top institutions, including the U.S. Naval Research Laboratory, developing ultra-precise brain thermodynamic sensors, and with the U.S. Department of Defense and Air Force on advanced laser technology. His work continues to push the boundaries of medical science and innovation.
