He has been interested in science from a very young age and really likes the mathematical applications of physics. He went to school in applied physics, working in the microelectronic industry with semiconductor devices and nanotechnology . He realized that rather than refining established techniques, he wanted to develop new technologies and contribute to humanity, so he moved to biophysics and biomedical applications. His latest project is the creation of a biosensor for the detection of tuberculosis. Dr. Krapf lives with his family near the Rocky Mountains and enjoys hiking, skiing, snowshoeing, and visiting the nearby national parks.
