Dr. Peter S Guzman is recognuzed the University of the Philippines Los BaƱos College of Agriculture Alumni Association (UPLBCAAA) recently conferred the College Distinguished Alumnus Award for Science and Technology in the field of Plant Breeding to Dr. Peter Guzman for his contributions in plant breeding. The award was presented during the 97th UPLB Loyalty Day and Alumni Homecoming last October 9. The Distinguished Alumnus award is the highest award given to the alumni of the college. It recognizes graduates who have excelled in their fields and provided significant contributions to society. Dr. Guzman (BSA '86 cum laude, MS '93) is a former UPLB professor and commercial pipeline breeder of Monsanto. He obtained his doctorate degree from Iowa State University, and a post-doctorate degree from the University of Illinois Urbana-Champaign. He is also an Outstanding Young Scientist (OYS) awardee in 2002. Dr. Guzman was cited for his contributions to agricultural instruction, research and extension, as well as his breakthroughs at Monsanto. At UPLB, Dr. Guzman had a pivotal role on developing a graduate course on the then emerging field of molecular plant breeding, while his extension work included the formulation and implementation of a seed production and distribution program for yellow and white corn varieties, benefiting around 20,000 resource poor farmers in the country. At Monsanto, he led in the establishment of the company's Harrisburg Corn Research Station in South Dakota, USA. According to a press statement, Dr. Guzman noted that his work at Monsanto allowed him to discover breakthrough solutions that improve the lives of our farmers. With regards to the recognition, he mentioned that it will serve as an inspiration in continuing his research on modern agricultural practices to address the pressing problems of food security and sustainability. Dr. Peter Guzman is a charter member of The UPLB Genetics Society.
