While an engineer, there are several things that really thrilled me, so to select one best thing is not easy. Recently, my engineering research led to the application of infrared imaging (a camera measuring temperature on the body) to a few interesting medical problems:
- The camera can 'see' pain by looking at temperatures on the body that are not symmetrical. For example, in the legs or on the back, a cold or hot spot on one side would indicate less blood irrigation or a nerve route irritation.
- We can also identify if people have rheumatoid arthritis by measuring temperature of the knuckles. Other joints also show the presence of RA such as knees, ankles, elbows.
- Babies who develop NEC (Necrotising entero-colitis, which is an inflammation of the bowel which can be severe enough to cause death in premature infants.) We can actually measure temperature inequalities of the belly and identify babies who have and those who have not developed NEC.
My students and I have many other projects that are as exciting. Biomedical engineering is a very exciting field with many new developments using robotics, nanotechnology, genetics, etc...
Good luck with your studies and choice of career.
