Craig Criddle is a Professor in the Department of Civil and Environmental Engineering at Stanford University, and a Senior Fellow at the Woods Institute for the Environment. He is the Institutional Co-I for CUBES at Stanford and the lead of the Biofuel and Biomaterials Manufacturing Division of CUBES.

Dr. Criddle is interested in the environmental engineering, science, and science literacy needed for clean water, clean energy, and healthy ecosystems. His research focus is environmental biotechnology. He is best known for large interdisciplinary field projects, studies of microbial
ecology in bioreactors, and work on microbial transformations of persistent contaminants. Some current projects include a field-scale evaluation of uranium remediation; DNA-monitoring of microbial community structure at full-scale biological wastewater treatment plants; development of membrane bioreactors for energy recovery and nutrient removal; and studies to elucidate the mechanisms and kinetics of microbial transformation of halogenated solvents. To promote science literacy, he worked with award-winning San Francisco cartoonist, Larry Gonick to write "The Cartoon Guide to Chemistry." "Cartoons can give us an intuitive feeling for the why, and deeper understanding can grow from that intuition."

Karen McDonald is a Professor of Chemical Engineering at the University of California at Davis.  She also previously served as the Faculty Director and Co-PI of the UC Davis ADVANCE Institutional Transformation program, a NSF-funded program to recruit, retain, and advance women STEM faculty.  She is the Institutional Co-I for CUBES at UC Davis and Division Lead for the Food and Pharmaceutical Synthesis Division.

Prior to leading the UC Davis ADVANCE program, she served as Associate Dean for Research and Graduate Studies in the College of Engineering for 13 years. She is a member of the graduate program/groups in Chemical Engineering, Biomedical Engineering, and Plant Biology and the Designated Emphasis in Biotechnology program.  From 2003-2015 she served as the Co-Director of the NIH Training Grant in Biomolecular Technology at UC Davis, an innovative multidisciplinary research and educational training for doctoral students working at the interface of life sciences and engineering/physical sciences in application areas related to human health. From 2006-2013, she was the PI and Director of the NSF Collaborative Research and Education in Agricultural Technologies and Engineering (CREATE) IGERT, an interdisciplinary graduate training program with Tuskegee University focused on applications of plant biotechnology to biopharmaceuticals, biorefineries and sustainable agriculture.

Dr. McDonald and her collaborators apply synthetic biology tools in plants for the development of novel expression systems as well as applying bioprocess engineering technologies to produce recombinant proteins (including human therapeutic proteins, enzymes for cellulose degradation, and biopolymers for materials applications) using whole plants, harvested plant tissues, or plant cells grown in bioreactors. As a biochemical engineer, she is interested in translational research and strives to develop novel biomanufacturing processes that are scalable, cost effective, and meet a variety of design constraints. She has lead large multidisciplinary research teams such as a Defense Threat Reduction Agency-funded project to develop a platform for plant-based production of bioscavengers against biothreat agents.
