Frex is a Wildlife Biology Major and a DOST scholar since his freshman year in college. He is working at the Museum for his practicum.

Young Frex was raised in an environment close to nature, which made him fascinated with life and its complexity, and inspired him to eventually take up BS Biology. He is now preparing for his undergraduate thesis on the natural history of bats specifically on their diet, behavior, population, activity, and reproductive conditions. After getting his BS degree, he plans to pursue a medical career.

During his leisure time, he plays the piano and trains a children's choir in Batangas. He is also involved in the youth ministry in the Archdiocese of Lipa. He is a member of UP ECOSS, an environmental organization based at the Institute of Biological Sciences, UPLB.
