Describe what you do in your current work situation. Hi! I'm a professor of biomedical engineering at Rose-Hulman Institute of Technology in Indiana. Some people may not be familiar with biomedical engineering, so let me tell you first of all that biomedical engineers use math, science, and engineering to understand and help treat medical problems. My field of expertise is cell and tissue engineering. Cell and tissue engineers combine knowledge from sciences (like biology and chemistry) with principles from traditional engineering fields (like electrical, mechanical, or chemical engineering). The scientific knowledge helps us understand how cells and tissues work; then we use our engineering skills to develop methods to control how the cells and tissues function. For example, understanding how bones heal when they are broken or injured, helps me figure out which chemicals in the body "tell" bone cells to make new bone tissue. I can then put similar chemicals on the surface of a biomaterial. A dental or orthopedic implant made out of that biomaterial would "tell" bone cells to make bone at the tissue-implant interface, and the implant would heal quickly and strongly. This is one of the projects I’ve worked on in my laboratory! Other examples of cell and tissue engineering research are: understanding how mechanical or electrical stimuli can affect the functions of cells and tissues, figuring out how to grow tissues or organs in a laboratory for patients who need transplants, and discovering ways to get cells in a patient's body to function a certain way (for example, to make a tumor stop growing). I really enjoy biomedical engineering, but that’s only part of my job. I am a professor at a school that is dedicated to teaching engineering, mathematics, and science, and teaching is my main job! I also study ways to help people learn, and I help other teachers, professors, and trainers learn about teaching and learning.
