Data Analytics for Assessing the Safety and Environmental Performance of Passenger Vehicles


As society advances to expect deeper understanding of human, natural and engineered systems, the methods needed to support public decisions also must advance. While systems engineering and analysis methods have flourished for years, emerging tools for managing, analyzing, and visualizing data are changing the way we understand and manage systems.

As public agencies are increasingly held to high standards of cost-effective program management, open data initiatives will lead to increased access to data.  As such, the bar must be raised in terms of how government decision makers understand the data life cycle in the social systems they manage.


At the same time, the era of connected and autonomous vehicles is emerging, which will cause dramatic changes on transportation infrastructure, but also will require government activities like vehicle inspection and maintenance programs to adapt quickly to the new challenges presented from these technological advances.


In this talk, I demonstrate several examples where changes in technology, practice, or data availability raise new questions about which policies should be put in place to maintain or improve safety and environmental performance. I will discuss assessing safety of current and emerging vehicles, and the reliance on on board diagnostic (OBD) technology in vehicles, and show various data analytic methods used to assess how we might continue to keep vehicles safe and clean.


Scott Matthews is a professor in the Department of Civil and Environmental Engineering and the Department of Engineering and Public Policy at Carnegie Mellon University. He is also a member of the Green Design Institute, an interdisciplinary research consortium at Carnegie Mellon focused on modeling energy and environmental problems as systems, building decision support tools, and supporting robust policy decisions under uncertainty.  

Matthews’s research and teaching focuses on valuing the socioeconomic implications of social systems, such as energy and transportation infrastructure. His work intends to facilitate economic and social decision-making under uncertainty via large datasets, computation, and visualization methods. 

Matthews has previously contributed to development of tools for environmental and energy life cycle assessment (LCA) of products and processes (such as the EIO-LCA model), estimating and tracking environmental effects across global supply chains (such as carbon footprinting), and the sustainability of infrastructure systems.

Matthews has served as chair of the Committee on Sustainable Systems and Technology with the Institute of Electrical and Electronic Engineers and on the Executive Committee for the American Center for Life Cycle Assessment. He participated in the National Research Council study on the Hidden Costs of Energy and is a member of the NRC Board on Environmental Studies and Toxicology.

At Carnegie Mellon, he has taught graduate and undergraduate courses in the Departments of Economics, Civil and Environmental Engineering, Engineering and Public Policy, and Computer Science.   

Electric Vehicles in the Smart Grid: Optimization & Control


The rapid electrification of the transportation fleet imposes unprecedented demands on the electric grid. If controlled, however, these electric vehicles (EVs) provide an immense opportunity for smart grid services that enable renewable penetration and increased reliability.

In this talk we discuss paradigms for aggregating and optimally controlling EV charging. Specifically, we discuss (i) distributed optimization of large-scale EV fleets, (ii) aggregate modeling via partial differential equations, (iii) and plug-and-play model predictive control.

The talk closes with future perspectives for EVs in the Smart Grid, and a short description of new project-based courses on Design of Cyber-Physical Systems taught at UC Berkeley.

He received the PhD degree from the University of Michigan in 2011, the MS degree from the University of Michigan in 2008, and the BS degree from the UC Berkeley, in 2006 - all in Mechanical Engineering. Moura was a postdoctoral scholar at UC San Diego in the Cymer Center for Control Systems and Dynamics, and a visiting researcher in the Centre Automatique et Systèmes at MINES ParisTech in Paris, France.

Moura is a recipient of the O. Hugo Shuck Best Paper Award, Carol D. Soc Distinguished Graduate Student Mentoring Award, Hellman Faculty Fellows Award, UC Presidential Postdoctoral Fellowship, National Science Foundation Graduate Research Fellowship, University of Michigan Distinguished ProQuest Dissertation Honorable Mention, University of Michigan Rackham Merit Fellowship, and Distinguished Leadership Award. He has received multiple conference best paper awards, as an advisor and student. His research interests include control & estimation theory for PDEs, optimization, machine learning, batteries, electric vehicles, and the smart grid.


Why did an environmental scientist and former regulator end up at one of the largest manufactures in the world? Sheryl Corrigan, Director of Environmental, health and Safety for Koch Industries, Inc., understands that successful industrial innovation requires efficiencies that create in-demand products and services that use less resources. Large manufacturers need employees that understand the balancing act of addressing environmental needs, business growth priorities, and consumer demand. Devoted to environmental work from the beginning, Sheryl’s career included roles at 3M and the Minnesota Pollution Control Agency where her passion for environmental science and safety grew and was matched by valuable leadership experience. She then brought that passion and experience to her role at Koch where she serves as the Director of Environmental, Health and Safety, driving environmental excellence initiatives across all Koch companies. By focusing on responsible operations and efficiency, Koch industries is not only making products and services we use every day, but meeting the challenge of producing more using less resources. As of 2012, there has been a 33% reduction in production related waste across Koch Companies while meeting market demands. Koch Industries has been recognized by the EPA for the third year in a row for being among the top two companies with the most pollution prevention initiatives.
During this seminar, Sheryl will discuss how a diversity of experience and approach can make you one of the most valuable people at the table and explore the interesting career paths at Koch Industries. With 120,000 employees worldwide and 70,000 strong in the U.S., Koch is integral to creating the essential products that benefit daily life most: food, shelter, clothing and transportation. By focusing on people and values, while having access to a multitude of industries and resources, employees have the opportunity to make a real impact in their careers.


Sheryl Corrigan is director of environmental, health and safety for Koch Industries, Inc., driving discovery of excellence and innovation opportunities, and providing oversight of Koch companies' environmental performance. Previously, Ms. Corrigan was senior vice president of environmental, health and safety for Flint Hills Resources, LLC; a subsidiary of Koch Industries.

Before joining Koch, Ms. Corrigan was commissioner of the Minnesota Pollution Control Agency, advising the governor and helping set the strategic direction for the state on environmental matters. She has also worked for 3M in a number of positions focusing on environmental, health and safety operational excellence.

Ms. Corrigan earned a bachelor's degree in geology from the University of Minnesota Institute of Technology.

Based in Wichita, Kansas, Koch Industries, Inc. is one of the largest private companies in America with annual revenues as high as $115 billion, according to Forbes.

Structural Testing at the Micro and Nano Scales: Breaking Invisible Specimens with Zero Force


In this talk, I will describe how a bunch of clever and hardworking students and research associates have pioneered the use of microelectromechanical systems (MEMS) platforms to measure the mechanical response of materials and structures at the micro and nano scales.

Selected examples include measurements of strength, toughness, high cycle and static fatigue of brittle MEMS materials, the strength, ultimate strain capacity and viscoelastic response of individual collagen fibrils, and the fracture energy of the carbon nanotube-epoxy matrix interface.

A brief description of several the theoretical and computational models that were inspired by the experimental observations will also be presented.
