Award:

Outstanding Young Scientist (Chemistry), NAST-DOST, 1980

del Rosario became a Director of the Institute of Chemistry, University of the Philippines Los Baños (UPLB) for nine years.

(Physical Chemistry) - Cornell University (USA) - 1966

Ph.D. He is well-known for his pioneering research and development work on unique and practical ethanol fermentation techniques utilizing a variety of substrates such as sugary substrates, novel starch substrates like cassava, unripe or reject bananas, and lignocellulosic agricultural wastes.

He developed and optimized pretreatment and saccharification procedures for these difficult-to-ferment lignocellulosic materials.

Dr. He pioneered the work on bioethanol production and is an expert in biofuels. Del Rosario, E.J., (1977) Cellulase production in semisolid cultures of trichoderma viride.
