Somayeh Nassiri, Associate Professor of UC Davis and Principal Investigator at the University of California Pavement Research Center
Lab2Slab2Practice presents a comprehensive risk management framework for accelerating the adoption of low-carbon concrete into standard practice based on systematic evaluation. The framework draws upon social behavioral models, including Kotter’s 8-Step Change Model, Diffusion of Innovations (DOI), and the Unified Theory of Acceptance and Use of Technology (UTAUT) to help identify and manage risks. These methods help to guide the novel technology integration process by addressing early adopters, building performance expectancy, reducing perceived user effort, leveraging social influence, and facilitating conditions.
By reliable, fast throughput experimentation at laboratory and slab scales, engaging all stakeholders, the framework aims to manage risks related to performance, scalability, and environmental impact, and reduce the adoption timeline for low-carbon materials from over 10 years to fewer years. Ultimately, this approach aims to institutionalize low-carbon concrete into state departments of transportation's specifications and building codes, thereby contributing to significant reductions in greenhouse gas emissions in infrastructure projects.
Somayeh Nassiri is a faculty member at the UC Pavement Research Center (UCPRC). She is interested in pavement materials and structural design techniques to improve pavement sustainability. These strategies include using more sustainable materials and construction practices for long-lasting and durable pavements. Others are to improve pavement structural design for new and rehabilitation projects and to optimize repair jobs in terms of materials, timing, and construction to extend the life cycle of pavements, among others. Dr. Nassiri teaches courses on the materials, design, repair, rehabilitation, and management of asphalt and concrete pavements.

Seth Kane, Postdoctoral Scholar, UC Davis Materials Decarbonization and Sustainability Center
Global materials production, as of 2019, exceeded 42.8 Gt and was responsible for over 25% of global anthropogenic greenhouse gas emissions. Simultaneously, global forestry and agriculture resulted in 9 Gt of underutilized biomass residues. The utilization of these residues in materials production represents a key pathway to reducing the burdens of materials production, creating long-term storage of atmospheric carbon, and meeting society’s material demands. There is also a growing and competing demand for biomass residues for energy production.
This seminar will discuss viable pathways to utilize biomass residues in concrete, steel, plastics, and other materials in the context of global material production, biomass residue availability, biomass properties, and material performance changes. We will highlight the role that biomass residues can play in existing roadmaps for industrial decarbonization of key materials, by informing robust supply chains using local resources and identifying hotspots to prioritize industrial and policy solutions.
Dr. Seth Kane studies sustainable materials and carbon sequestration in the built environment, with goals of emissions reductions and mitigation of damage to heavily impacted communities. His work encompasses materials (including polymer, cementitious, biomass, carbon, and composite) and technologies (including pyrolysis, additive manufacturing, alternative recycling, and energy storage) and is inspired by his first-hand experience with how a warming climate impacts both the natural and built environments, having grown up in interior Alaska. Dr. Kane completed his PhD in Mechanical Engineering with a Materials Science focus at Montana State University and is currently a postdoctoral scholar at UC Davis, focusing on industrial ecology in Civil & Environmental Engineering.

Sabbie Miller, Faculty Director, UC Davis Materials Decarbonization and Sustainability Center
Materials like plastics generate high emissions during production due to energy-intensive processes, while others, such as cement and concrete, have high emissions largely due to their massive scale of consumption in construction. This seminar will provide a primer on key drivers for these and other materials, which contribute disproportionately to global emissions. We will explore the specific emission challenges associated with four key materials—cement/concrete, steel, plastics, and bricks—and discuss the unique obstacles and opportunities for decarbonization in each. Attendees will gain insight into technological, policy, and design innovations that can help reduce the carbon footprint of these essential materials.
