Roderic Ivan Pettigrew, PhD, MD is the Robert A. Welch Professor of Medicine, and serves as CEO of Engineering Health (EnHealth) and executive dean for Engineering Medicine (EnMed) at Texas A&M and Houston Methodist Hospital where he is Adjunct Professor of Nanomedicine. He was the founding Director of the US National Institute of Biomedical Imaging and Bioengineering (NIBIB) of the NIH [2002-2017], oversaw $5 billion in research investments and is credited with building it into the signature NIH institute for emerging medical technologies. Of note, under Dr Pettigrew’s leadership, NIBIB produced more patents per appropriated dollar than any other institute or federal agency returning $30 per each $1 invested in research or 3000% (5 x the already remarkable NIH Average of 600%). On the 10th anniversary of NIBIB, the U.S. Senate unanimously passed a resolution commending the institute for its leadership and impact in improving the nation’s health through technological innovation.

His newest undertaking is EnHealth, the world’s first initiative to holistically integrate engineering into all of the colleges of a university that are a part of the health care enterprise. EnMed is the first constituent initiative, creating a new school that integrates engineering into medical training to develop a new kind of engineering-minded physician, or Physicianeer, who invents solutions to healthcare problems.  Of note, an invention is required of each EnMed graduate who will earn both MD and MEng degrees in 4years.

Dr. Pettigrew’s expertise is in health technologies emerging from the convergence of the life sciences, the physical sciences and engineering.  An MIT graduate (PhD ’77) who finished his medical training at UCSD (’83), he is known internationally for his pioneering work involving four-dimensional imaging of the cardiovascular system using magnetic resonance (MRI). His current knowledge base also includes nanotechnology, regenerative medicine, and point-of-care technologies. He has been elected to membership in the National Academy of Medicine, the National Academy of Engineering, the National Academy of Inventors and the National Academy of Sciences, India. Other awards include the Pierre Galletti Award (highest honor) of the American Institute of Medical and Biological Engineering, the Inaugural Gold Medal of the Academy of Radiology Research, the Distinguished Service Medal of the International Society of Magnetic Resonance in Medicine, the Spirit of the Heart Award of the ABC, the Pritzker Distinguished Achievement Award of the Biomedical Engineering Society, the Gold Medal of the Radiological Society of North America, and the Arthur M. Bueche Award of the National Academy of Engineering.

Current advisory service includes the Phil and Penny Knight Institute for Accelerating Scientific Impact External Advisory Board, the Stand Up To Cancer Scientific Advisory Board and the Allen Institute Scientific Advisory Board.
