He led several teams in advancing the design and development of microchips in the semiconductor industry while also completing his Masters in Electrical Engineering at Southern Methodist University. During his career, Bob held 14 patents for innovative technology and was awarded the esteemed title of TI Senior Fellow.

He spent his free time pursuing passions such as raising cattle, gardening, and golfing. He served on the volunteer board of the McKinney Pinto Riding Club where he encouraged children and families to enjoy developing horsemanship skills.
