Life Cycle Assessment (LCA) seeks to quantify the environmental impacts of product systems and services from “cradle-to-grave”, or from raw material extraction through the end-of-life. The ideal outcome of this exercise is the identification of actions that can be taken by firms and policymakers to reduce global environmental damage. LCA is quite young relative to the classical academic disciplines, and faces significant challenges in establishing its relevance for decision-making. Mainstream LCA practice seeks to account for environmental damage in a way that is fair and consistent to stakeholders using a class of models termed Attributional LCA (ALCA). In this process, many steps are taken to allocate inputs, outputs and emissions over product systems that interact with each other. Allocation schemes simplify these interactions in such a way that the environmental consequences of decisions are not always identified by ALCA results. My thesis seeks to develop and demonstrate new methodologies pertaining to Consequential LCA (CLCA), which has not been standardized and fully adopted in mainstream practice. In my approach to CLCA, I seek to assess the net environmental outcomes of decisions, rather than attribute environmental impacts in a fair and consistent way across product systems. This leads to an inevitable focus on the uncertainties driven by social dynamics and the pursuit of causal inference, which are scarcely addressed in the LCA field.

Jason Maier

BS, University of California, Santa Barbara, Biochemistry
ME, University of California, Berkeley, Civil and Environmental Systems

The understanding of individual and household consumption patterns is a vital component in designing a sustainable future. While historically sustainability science has focused on eco-efficiency, it is becoming ever more clear that a decrease in consumption of highly impactful goods must accompany efficiency gains in order for significant environmental benefit to be realized. Jason uses life-cycle assessment, microeconomic theory and behavioral economics as a lens to better understand current consumption patterns, the impacts of potential shifts in consumption, and the behavioral motivations for shifts in preference.

Jessica Couture

MESM, University of California, Santa Barbara, Environmental Science & Management
BS, University of California, Santa Cruz, Marine Biology

Jessica is interested in sustainable food systems with a focus on fisheries and marine aquaculture. She earned a bachelors degree from UC Santa Cruz in marine biology and gained extensive experience in field ecology and marine science, early in her career. Specializing in Coastal Marine Resource Management, she studied fishing alternatives and community-scale aquaculture in coastal communities of Mexico for her master’s theses, earning a master’s of environmental science and management degree from the Bren School of Environmental Science & Management. After graduating, Jessica worked as a data manager working on synthesis science projects and facilitating open science in research. 

As a PhD student she calls upon her background in field ecology, data science and modeling to assess the ecological and environmental impacts of marine aquaculture. Specifically, she uses life cycle assessment methods to estimate the environmental impacts of fish feeds and how novel ingredients might help make aquaculture more sustainable overall. Jessica continues to be an advocate for open science and open data practices, promoting the benefits and techniques of these approaches locally and among the broader scientific community.

Timnit Kefela

MS, Rutgers University, Camden, Biology
BS, Rutgers University, Camden, Biology

Timnit’s doctoral research focuses on understanding the ubiquity and effects of synthetic microfibers and nanomaterials in freshwater, marine and terrestrial environments. Her previous research experiences include understanding the growth and pathogen control effects of leguminous associating rhizobacteria on non-leguminous plants and the role of rhizobacteria in drought stress tolerance of plants. Timnit is committed to connecting people to science, the diversification of STEM and environmental spaces. She previously interned for The Philadelphia Science Festival where she helped develop programming, served as an educator as a LEAP Academy Chemistry Teaching Fellow, Rutgers Civic Engagement Graduate Fellow and Rutgers Camden Faculty of Arts and Sciences Part-Time Lecturer and led experiential learning food justice initiatives as the LEAP STEAM Fabrication Lab Graduate Fellow in Camden, NJ.


Adriana Dominguez (post doc)

PhD, University of Zaragoza, Spain, Renewable Energy and Energy Efficiency
Master, University of Zaragoza, Spain, Renewable Energy and Energy Efficiency
MBA, La Salle Bajio University, Mexico, Management
MS, University of Guanajuato, Mexico, Mechanical Engineering
BS, University of Guanajuato, Mexico, Mechanical Engineering

Adriana Dominguez is a postdoctoral researcher at Bren School of Environmental Science and Management at the University of California at Santa Barbara. She is a forward-thinking scientist with a multidisciplinary background (Mechanical Engineering, Administration, Environmental Science, Renewable Energy and Energy Efficiency) and 10+ years of research experience in developing sustainability indices and assessment tools for energy efficiency and natural resource conservation. Prior to joining UCSB, she was a researcher at CIRCE, Spain. She is an excellent team player and a strong builder of prolific collaborations validated by 10 international projects in America and Europe, resulting in 25 peer-review publications, 17 international conference presentations and 2 years of teaching experience. She loves sports of all kinds, such as riding horses, running, soccer, snowboarding and surfing. She is currently working on the integration of Techno-Economic Analysis and Life Cycle Assessment to evaluate the end-of-life of photovoltaic solar panels.

Huseyin Sarialtin

PhD, Ege University, Solar Energy Institute
, UC Riverside, Mechanical Engineering

Huseyin Sarialtin completed his bachelor of science with high honor in 2006. Then, he moved to UC Riverside where he studied the role of graphene as an electrode support material in Direct Formic Acid Fuel Cells (DFAFC) and earned his M.S. degree in 2010. Following his degree, Huseyin pursued in depth research experience, working as a researcher in Izmir Institute of Technology and assessing photovoltaic technologies on a European Union project in Augsburg, Germany. In 2014, he started PhD on sustainable energy analysis of next-generation photovoltaics. Between 2017 and 2018, he worked with Roland and his lab at the Bren School at UC Santa Barbara as a visiting researcher applying LCA to his research on photovoltaics. Huseyin earned his PhD degree titled Life Cycle Assessment of Perovskite Solar Cells in 2019.
