New faculty member Sam Coogan connects civil and electrical engineering to run the transportation systems of tomorrow

Sam Coogan joins the Georgia Tech faculty this fall as an assistant professor in both the School of Civil and Environmental Engineering and the School of Electrical and Computer Engineering.

A new faculty member with one foot in electrical engineering and another in civil engineering is working to make sure the transportation systems of the future can accommodate all the different demands they will face, from self-driving cars to technologies we haven’t even imagined yet. Sam Coogan joins the Georgia Tech faculty this fall as an assistant professor in both the School of Civil and Environmental Engineering and the School of Electrical and Computer Engineering.

Smart Cities: Innovative approaches combining engineering, technology and the social sciences are boosting the urban IQ

Smart Cities graphic with a rendering of the city of Atlanta.

Georgia Tech has been intensifying its smart cities initiative, including membership in the national MetroLab Network and the launch of a new faculty council with members from more than a dozen university units. Tech has long been working in the, but the now the Institute is organizing all the research that’s happening to have a bigger impact.

For a researcher who studies the ways society’s infrastructure systems are interconnected and interdependent, the Interstate 85 collapse this spring in Atlanta had a silver lining. School of Civil and Environmental Engineering Assistant Professor Iris Tien told Atlanta public radio station WABE that shutting down one of the city’s main thoroughfares presented a rare opportunity — despite the disruption to businesses and the extra travel time for residents.

Dealing with uncertainty: New NSF project will create more accurate, faster interval-based approach to assessing structures for damage

Yang Wang and students in his research group install sensors on a bridge in Bartow County, Georgia, in July 2016. Wang, Francesco Fedele and Rafi Muhanna in the School of Civil and Environmental Engineering will use data from instruments like these to feed a new interval-based optimization approach to assess structural systems and detect damage. (Photo Courtesy: Yang Wang)

The National Science Foundation has funded a new collaboration between three School of Civil and Environmental Engineering researchers that could make finding damage in bridges or buildings easier and help reduce life-threatening failures. If successful, the team will be able to produce more reliable predictions about how structures behave, and their algorithm will be able to do the predictions much more quickly than current practice for structural damage and deterioration assessments.

Tien: Pipeline blast reminds us of our dependence on a few key infrastructure systems

Sierra Magazine story about the explosion at a gas pipeline in Alabama.

The shutdown of the Colonial Pipeline in Alabama after an explosion Oct. 31 underscores how little redundancy exists in many of our key infrastructure systems, according to the School of Civil and Environmental Engineering’s Iris Tien.

Chloe Johansen, a School of Civil and Environmental Engineering Ph.D. student, is working on an idea with Assistant Professor Iris Tien they think will make a difference in improving America's crumbling infrastructure. It's work with so much potential that Johansen is working with other Georgia Tech and Emory University graduate students to commercialize her research.

Tien: What we build builds communities

A neighborhood on the Westside of Atlanta, an example of the premise that has been stuck in Iris Tien's mind recently: how the infrastructure civil and environmental engineers build — or the lack thereof in areas like this — influences the surrounding community. (Photo: Iris Tien)

In a blog post for the Georgia Tech Center for Serve-Learn-Sustain, Iris Tien lays out the importance of civil infrastructure in building communities.
