Four Georgia Institute of Technology faculty members have been elected as new members of the National Academy of Engineering (NAE). Marilyn Brown, Thomas Kurfess, Susan Margulies, and Alexander Shapiro join 83 other new NAE members for 2020 when they are formally inducted during a ceremony at the academy’s annual meeting on Oct. 4 in Washington, D.C.

Election of new NAE members, the culmination of a yearlong process, recognizes individuals who have made outstanding contributions to "engineering research, practice, or education, including, where appropriate, significant contributions to the engineering literature" and to "the pioneering of new and developing fields of technology, making major advancements in traditional fields of engineering, or developing/implementing innovative approaches to engineering education."  

“It’s the honor of a lifetime to be recognized by the National Academy of Engineering for the impact we’ve have on understanding lung injuries in the critical care unit and traumatic brain injuries in children,” said Margulies, chair of the Wallace H. Coulter Department of Biomedical Engineering at Georgia Tech and Emory University and, with Brown, one of just three women on the Georgia Tech faculty accorded NAE membership – one of the highest professional distinctions an engineer can receive.

“Our work is deeply collaborative, and I am grateful to the engineers, scientists, physicians, and patients who are partners in our journey,” Margulies added.

Margulies, a researcher in the Petit Institute for Bioengineering and Bioscience at Tech and a Georgia Research Alliance Eminent Scholar in Injury Biomechanics at Emory, was elected, “for elaborating the traumatic injury thresholds of brain and lung in terms of structure-function mechanisms,” according to the NAE announcement.

Using an integrated biomechanics approach, Margulies’ research program spans the micro-to-macro scales in two distinct areas, traumatic brain injury and ventilator-induced lung injury. Her work has generated new knowledge about the structural and functional responses of the brain and lungs to their mechanical environment. Margulies came to Georgia Tech in 2017 from the University of Pennsylvania, where she’d been a professor of bioengineering, and had earned her Master of Science in Engineering and Ph.D. in Bioengineering.

Brown, a Regents and Brook Byers Professor of Sustainable Systems in the School of Public Policy, was co-recipient of the Nobel Peace Prize in 2007 (for co-authorship of the Intergovernmental Panel on Climate Change Working Group III Assessment Report on Mitigation of Climate Change, Chapter 6). 

She joined Georgia Tech in 2006 after a career at the U.S. Department of Energy's Oak Ridge National Laboratory, where she led several national climate change mitigation studies and became a leader in the analysis and interpretation of energy futures in the United States. Her research at Tech focuses on the design and impact of policies aimed at accelerating the development and deployment of sustainable energy technologies, emphasizing the electric utility industry. She was elected to NAE “for bridging engineering, social and behavioral sciences, and policy studies to achieve cleaner electric energy.” 
 
Brown, who earned her Ph.D. at the Ohio State University, co-founded and chaired the Southeast Energy Efficiency Alliance, served two terms as a presidential appointee on the board of the Tennessee Valley Authority – the nation’s largest public power provider – and also served two terms on the U.S. Department of Energy’s Electricity Advisory Committee, where she led the Smart Grid Subcommittee. 

“The most rewarding feature of my career has been working toward solutions with colleagues across disciplines,” Brown said.

Shapiro is the Russell Chandler III Chair and professor in the H. Milton Stewart School of Industrial and Systems Engineering, where his research is focused on stochastic programming, risk analysis, simulation-based optimization, and multivariate statistical analysis.

In 2013, he was awarded the INFORMS Khachiyan Prize for lifetime achievements in optimization. He received the 2018 Dantzig Prize from the Mathematical Optimization Society and the Society for Industrial and Applied Mathematics.

Since earning his Ph.D. in applied mathematics-statistics from Israel’s Ben-Gurion University of the Negev in 1981, Shapiro has made substantial contributions to the fields of optimization and large-scale, stochastic programming, and he was elected to NAE “for contributions to the theory, computation, and application of stochastic programming.” 

Kurfess is professor and HUSCO/Ramirez Distinguished Chair in Fluid Power and Motion Control in the George W. Woodruff School of Mechanical Engineering, where he has helped guide the evolution of technology as a pioneer in the digital transformation of manufacturing. 

Improving manufacturing technology is a pursuit that has roots in his childhood. “I grew up in my father’s machine shop,” said Kurfess, who has a special fondness for mom-and-pop operations. He was elected by the NAE “for development and implementation of innovative digital manufacturing technologies and system architectures.”

“I’m proud that the work we do has a positive impact on small and medium-sized enterprises, which are about 99% of the manufacturing operations, as well as large operations,” said Kurfess, who earned all of his degrees at MIT. “Our work targets people who are implementing the digital thread in manufacturing, and what the digital thread will do is make sure those smaller enterprises, those mom and pops, can have access to the latest and greatest technologies.”

Even if you do your best to eat local, chances are most of the fruits and vegetables you consume come from far away -- especially if you live in a big city. Water and land for growing crops are hard to come by in urban areas. Finding more sustainable methods for growing produce in urban areas would have enormous benefits. A pilot project by Georgia Tech’s Yongsheng Chen, a professor in the School of Civil and Environmental Engineering, aims to use wastewater from the campus to do just that. 

“The overarching goal is trying to figure out a way to use wastewater nutrients to grow produce in urban areas so we can decentralize vegetable production,” Chen said. A grant provides $5 million over five years from the U.S. Department of Agriculture’s National Institute of Food and Agriculture (NIFA) to create and operate a hydroponic growing system using domestic wastewater extracted from the Georgia Tech campus sewer system. It is the largest USDA award Georgia Tech has received. 

“Currently we treat wastewater by taking all the nutrients from it,” said Chen. “Then we have to use an energy-intensive process to synthesize and add fertilizer to the food production process.” 

The proposed anaerobic membrane biological treatment process will transfer organic contaminants into biogas and remove pathogens such as E. coli to ensure food safety, but the nutrients (nitrogen, phosphorus and potassium, for example) will remain. By using a smart membrane or nanomaterials to extract trace contaminants like endocrine disruptors, heavy metals and pharmaceuticals, the nutrients that are left can be pumped through a vertical hydroponic system to grow produce without adding fertilizer. The project will monitor water and produce quality and measure contamination from chemicals and microbes continuously.

The overall goal, said Chen, is to show that using the nutrients and water resources from domestic wastewater (DWW) in an urban controlled environment agriculture system (CEAs) is socially, environmentally and financially sustainable and can easily be replicated in other cities. The project will closely track nutrient requirements, energy needed to produce, handle and transport the fruits and vegetables, and water needs to determine what resources are needed to support this kind of CEA system (DWW-CEAs).

Ecological network analysis for DWW-CEA coupling will track material and energy flows across components that produce, consume and recycle food. Using a geodesign approach, Chen’s team will then compare data from traditional agriculture and DWW-CEAs to see how the system performs and how it could be designed to perform better in terms of water, energy and nutrient needs.

“Our model will have options to calculate energy consumption for the system, water consumption, water balance and nutrient balance,” said Chen. “We’ll conduct a life-cycle analysis and techno-economic analysis to evaluate whether this type of system will be commercially feasible or profitable in different locations, not just Atlanta.”

Chen will use machine learning in the controlled growing environment to seek a “recipe” for each plant type: the ideal amount of nutrients, growing temperature and humidity needed for lettuce, for example, so that each head of greens will taste the same. The project also provides an opportunity to test a number of other technologies, such as using solar power for cooling or biogas extracted from the wastewater and discarded food to power a micro chiller. 

Of course, showing that such a DWW-CEA system is feasible and profitable is one hurdle – another is getting consumers on board with the way the produce is produced. “If we are going to decentralize this system, what are the implications for policy related issues?” Chen asked. “Will people buy products produced by wastewater?” The project will involve working with a number of collaborators at Georgia Tech and in Atlanta, including Kaye Husbands Fealing, professor and chair of the School of Public Policy at Georgia Tech, and the Mayor’s Office of Sustainability.

“We want to change the current wastewater treatment practice, step back a little bit and think outside the box,” Chen said. “This could have a big impact locally, regionally or even nationally and internationally.”

This research is supported by the U.S. Department of Agriculture’s (USDA) National Institute of Food and Agriculture (NIFA), Agriculture and Food Research Initiative (AFRI) Water for Food Production Systems (Grant 2018-68011-28371).
