JOVITA D. LAYOSO- MOVILLON, PhD, is a Professional Sugar Technologist (No. 88); and a U.P. Professor 10 (SG 29/8) of the Department of  Chemical Engineering, CEAT-UPLB. She earned her B.S. in Sugar Technology degree in 1973; worked as Research Asst. of Dr. Ramon L. Samaniego, Sept. 1, 1973-June 30, 1975 in the Sugar Tech Prog. (then with CA-CAS); UPLB faculty member since July 1975.

She pursued her MS and PhD degrees, while teaching Sugar Tech. courses; and conducting research (NRCP study leader) on “Trichoderma protein production from sugarcane bagasse, pith and trash” (subsequently published and won the Best Technical Paper Award in the 1975 PHILSUTECH Convention); and also serving as Assoc. Editor, then Editor of Crystallizer (The Technical Magazine for the Sugar Industry) until 1986. She transferred to CEAT during its foundation on Feb. 24, 1983, along with the other Sugar Tech Program's faculty, staff and resources, to form the Department of Chemical Engineering. She earned her graduate degrees: MS in Agronomy in 1977 (Major: Crop Physiology; Minor: Biochemistry), with a graduate thesis on “In vivo Inhibition of Sugarcane Invertase”; and PhD in Agronomy(Sugarcane Production) in 1986 ; with 2 Cognates: a) Production Economics; &, b) Marketing), with dissertation on “Economic Efficiency of 75 Sugarcane Farms in Canlubang Mill District, Philippines”.

She had continuing post-graduate training in several raw sugar factories and refineries (4X) ; & 8-month sugarcane JICA training in Okinawa, Japan; conducted chemical engineering researches as DOST-JSPS exchange scientist (4X) in Tokyo Institute of Technology, Tokyo, Japan, 1992-99. She has authored 1 lab. manual; co-authored 4 lecture syllabi, 24 refereed papers, 42 papers in proceedings, 42 technical posters, 7 papers in bulletins, 3 policy papers, 17 papers in non-refereed journals, and about 12 unpublished reference materials; delivered 5 professorial chair lectures; presented several technical papers in local and international conferences, workshops & seminars; co-author of a book, soon to be published : “Biofuels: Domestic Prospect” by R. F. Rañola, Jr. , J.L. Movillon & R.B. Demafelis.
