Every day devices like the thermometer and stethoscope have become mainstays of modern medicine, but recent advances have significantly improved the ways in which doctors can confidently make diagnoses. While some procedures can be complicated, invasive, and expensive, we are getting closer to overcoming these barriers with the use of technology. In this episode, we discuss the interface between engineering and medicine with Dr. Michael Cima, a leading expert in the field of materials science and engineering. He discusses the development of a medical device that can identify excess fat and scar tissue in the liver – and the best part is that it’s non-invasive and portable. The device will allow doctors to easily screen at-risk patients for liver damage, helping them make treatment decisions to prevent the progression of non-alcoholic fatty liver disease (NAFLD). Dr. Cima also tells us about the many hats he wears as an engineer, scientist, entrepreneur, and mentor. Music by Kevin MacLeod licensed under CC BY 4.0.
