In 1985, Dr. Hooker earned his bachelor of science degree in chemical engineering, from California State Polytechnic University, Pomona, California. He earned his master's of science degree in 1988 and his doctorate in 1990, both in biochemical engineering, from Washington State University, in Pullman, Washington.

Hooker manages applied plant and fungal molecular biology research projects, including development of plant-based biosensors and transgenic production systems for human pharmaceutical proteins and industrial enzymes at the Pacific Northwest National Laboratory, where systems biology researchers are focused on understanding gene and protein networks involved in individual cell signaling, communication between cells in communities, and cellular metabolic pathways. Hooker has also been involved in research on microbial kinetics and transport mathematical modeling, design, development, and support for biological destruction of chlorinated organic hydrocarbons, development of tP4 transgenic plant protein production platform technology, and development of the RT3D bioremediation/natural attenuation software package.

Hooker earned the Battelle Entrepreneurial Award in 2001, and a Federal Laboratory Consortium Recognition Award in 1999, for his work on “Reactive Transport in 3-Dimensions.”
