Fall 2025

Blending documentary storytelling with technical analysis, this seminar will examine the hidden afterlife of electric vehicles through the lens of the US–Mexico used vehicle trade, while shedding light on broader global dynamics of transnational mobility and material flows.

While the use of cement powder for stabilization of aggregate base materials has been historically limited to rural roads where cement dust can be more easily tolerated, the use of cement slurry is becoming popular for pavement construction in urban areas where cement dust cannot be tolerated. Because cement slurry can be prepared at a concrete batch plant and then delivered to a job site and applied to the grade using a ready-mixed concrete truck equipped with a Slurry Spreader, this approach is readily available in most urban areas and is scalable for use on both small and large proj

Effective leadership is a skill that can be learned, developed and sharpened over time and every great leader starts with one thing: self-awareness. In this seminar, we’ll explore how understanding ourselves—our habits, strengths, and challenges—can transform the way we lead and connect with others. Together, we’ll examine communication strategies, the impact of sleep hygiene, and practices that support mental wellness, equipping you with tools to thrive personally and professionally. 

We will look at the research evidence for increasing physical activity at the population level, examine 4 countries that have managed to apply this evidence reasonably well, and assess the challenges of turning research into policy and then into practice. We will also look at scaling up research to broad application, in particular for active transport.

Globally, over half the world’s population lives in urban areas, but that proportion is rising steadily due to rapid development in countries of the Global South, such as India. Most of this urbanization, however, occurs with little planning, resulting in relatively congested and irregular building and road morphology. In these environments, economic activities such as stores and restaurants tend to be very close to major roads. Moreover, a lack of pedestrian infrastructure often leads to pedestrians sharing the same roadside environment as these economic units.

Heavy-duty Road transportation is one of the hard-to-abate transportation sectors globally. Battery electric trucks (BETs), fuel cell electric trucks (FCETs), and low-carbon liquid fuels (biodiesel and e-diesel) have been suggested as approaches to decarbonize heavy-duty transportation. However, technical and economic barriers limit their broader implementation, and the diverse usage scenarios of heavy-duty transportation requires fleet-tailored solutions.

Todd will talk about the challenges to oversee the health and improvements of over 700 centerline miles of roadways and over 100 bridges in Yolo County, CA.
