Dr. Elliott Campbell is an Associate Professor and the Stephen R. Gliessman Presidential Chair in Water Resources and Food System Sustainability in the Environmental Studies Department at UC Santa Cruz. Dr. Campbell’s research emphasizes the use of regional and global models to extrapolate from small-scale field measurements to policy-relevant spatial scales, particularly within the context of agroecology and global biogeochemical cycles. This work has led to his CAREER award from the National Science Foundation, appearances in media ranging from NPR to The Economist, and consultations to the U.S. EPA and other government agencies. He serves on the Associate Editorial Board at Frontiers in Ecology and the Environment and the faculty advisory committee at the University of California President’s Postdoctoral Fellowship Program.





The laboratory of Professor Manel Camps studies the biological consequences of random changes in genetic information (mutations). The main approaches include directed evolution, i.e. the generation of random mutant libraries coupled with specific selections or screens for new biological activities and also a variety of bioinformatics and statistical approaches for the study of mutational signatures (as indicators of distinct sources of mutations) and for the identification and quantification of patterns of co-occurrence or mutual exclusion between mutations or genes undergoing specific selective pressures (as indicators of functional overlap).





Yihsu Chen is a Professor in Technology Management in Sustainability, Electrical, and Computer Engineering at the University of California Santa Cruz. Prior to joining UCSC, he held a faculty position at University of California Merced with a joint appointment with School of Engineering and School of Social Sciences, Humanities and Arts. He is also affiliated with UCE3 (University of California Center for Energy and Environmental Economics). Professor Chen’s main research focuses on studying the impact of public policies on energy, water resources and transportation sectors. His research takes interdisciplinary approaches: quantitative models built upon economic principles and solved with operations research techniques. His work has received a number of INFORMS ENRE awards: 2004 best student paper (first place), 2013 and 2014 best publication in sustainability in second place and first place, respectively. Professor Chen’s work typically is policy relevant. In particular, his work on emission trading policies has received considerable attention and also directly contributed to policy debates. For example, his early work with Energy Research Centre of the Netherlands (ECN) on the European ETS (Emission Trading Scheme) windfall profits led to the European Commission auction off emission allowances in the second phase of the ETS. The work has received 700 Google citations. His work on the equivalence of emission trading programs with different point-of-regulation also partly helped the California Air Resources Board finalize their decisions in implementing first-sellers approach to control greenhouse gas emissions associated with imported power. His other work includes life-cycle analysis of biofuel production and the air pollution impact of the public transit system, evaluation of ecosystem services, etc. Professor Chen is also an associate editor of IEEE Transactions on Power Systems (2013 –2019) and ASCE Journal of Energy Engineering (2013 — present) as well as on the international advisory board of Energy Policy (2017–present). He has co-edited a few special issues in Journal of Energy Engineering (2010), IEEE Transactions on Power System. He served as the newsletter editor of INFORMS ENRE during 2010-2013.
