This study launched him into bioengineering, a discipline where he worked until his retirement. He was the first to patent the microbubble used as ultrasonic contrast. During those years, he garnered more than 100 scientific publications including: scientific papers, technical reports, chapters of books, scientific abstracts, and patents. He retired as a bioengineer and purchased land within the confines of a National Forest. He purchased a tractor with ancillary equipment and a one-man sawmill to established a homestead.
