Dr. M. Marc Abreu

Founder and CSO

Innovator, medical doctor and academician, Dr. Abreu has a background from Harvard Medical School and Yale University, where he served as clinical faculty in the Department of Anesthesiology and was a post-doctoral fellow and faculty in the Department of Ophthalmology and Visual Sciences.

He discovered the brain thermal tunnel, which for the first time in history enabled noninvasive, continuous measurement of human brain temperature. He also developed proprietary thermal measurement systems, devices and applications based on the brain thermal tunnel. Brain Tunnelgenix Technologies Corp™, with offices in Connecticut and Florida, is currently developing subscription-based services to help consumers manage chronic conditions such as sleep disorders, Multiple Sclerosis, Parkinson’s Disease and Alzheimer’s Disease.

Dr. Abreu is a pioneer in research on body thermal energy, having studied brain thermodynamics for two decades and inventing technologies that resulted in multiple patents. He developed the Abreu BTT™ 700 system, an FDA-cleared, computer based device that utilizes a micro sensor positioned on the brain thermal tunnel skin surface in the eyelid near the bridge of the nose, which measures brain temperature. The device renders the most accurate and true body temperature without corrective factors found in other digital and infrared thermometers.

Dr. Abreu is a pioneer in research on body thermal energy and brain thermodynamics, who discovered the brain thermal tunnel which was featured in a press release by Yale University, stating that for the first time in history brain temperature has been measured noninvasively and continuously


This technology helps medical professionals, employers, coaches and individuals capture brain thermal signatures, which can be used to prevent death from high or low body temperature, and has the potential to detect and manage a host of human conditions and diseases.

His previous accomplishments and scientific achievements include: while at Harvard developed advanced laser systems in association with the U. S. Department of Defense and U.S. Air Force; patented opto-electromagnetic tonometric systems and licensed it to Nestlé and its pharmaceutical unit, Alcon Laboratories; worked on spectroscopy culminating with the identification of the Radiation Signature of Glucose within the mid-infrared wavelength irradiated as thermal energy from the body. Dr. Abreu also developed the first FDA-cleared computer system for continuous temperature measurement during surgery, intensive care and general monitoring in association with ASUS Corporation.
