As a graduate research assistant in mechanical engineering, Randall played a central role in the founding of the National Gas Machinery Laboratory (NGML) at Kansas State University. The NGML, one of the university's most successful institutes, develops practical, cost-effective solutions for the natural gas transmission industry.

Randall's interest and inspiration in patent law can be attributed to his father, who was chosen as a national semifinalist in the History Channel's 2006 "Invent Now" competition.
