Ebenezer Fanijo

Ebenezer Fanijo's profile picture
ebenezer.fanijo@design.gatech.edu

Fanijo’s research centres around sustainable and smart-resilient buildings/civil infrastructure with a particular interest in decarbonizing infrastructure using novel low-carbon construction materials and alternative energy sources. Buildings contribute to more than one-third (39%) of the global energy-related CO2 emissions and 35% of global energy consumption, mainly from manufacturing, building materials and transportation. As such, advanced research on developing innovative construction materials is urgently required to address the carbon emissions from materials and construction processes of buildings' life cycle. His research approach includes examining the fresh properties and rheology, early-age cracking, microstructure evaluation, mechanical and durability performance, and life cycle assessment of building systems (particularly cementitious composites) made with these sustainable construction materials. 

He has also conducted research across different disciplines, including cementitious and concrete composites; corrosion monitoring and mitigation; concrete durability; green concrete technology using recycled and by-product materials; 3D printing of cementitious materials; highway pavement; geopolymers; fibre-reinforced concrete; advanced sensing technologies and automation; and non-destructive structural monitoring and evaluation. 

Fanijo received his B.S. in Building Construction with first-class honours from the Obafemi Awolowo University, Nigeria. In 2019, He earned an M.S. in Civil Engineering from the University of Idaho. Subsequently, he got his PhD in Civil Engineering (with a simultaneous Master’s degree – MEng in Material Science and Engineering) from Virginia Tech in 2022. He has worked on numerous funded research projects and published in various peer-reviewed journals and proceedings. Fanijo has also received numerous national and international awards for his excellence in research, with his recent NSBE Golden Torch Award recognized as the graduate student of the year 2022. 

At Georgia Tech, he is passionate about teaching construction materials and methods and their critical role in the design and construction of buildings. Fanijo developed and currently teaching the Construction Materials and Methods Course so that Building Construction students can have in-depth knowledge of building materials and systems, their properties, and their intrinsic relationship to structural systems and environmental performance. He also develops and teaches courses on Green Construction Technology, Concrete Durability and Sustainable Construction Materials and Techniques. 

Fanijo is a Professional Engineer (P.E.) and LEED Green Associate with more than five years of working experience in the construction sector.

Micah Ziegler

Micah Ziegler 's profile picture
micah.ziegler@gatech.edu

Dr. Micah S. Ziegler is an assistant professor in the School of Chemical and Biomolecular Engineering and the School of Public Policy.

Dr. Ziegler evaluates sustainable energy and chemical technologies, their impact, and their potential. His research helps to shape robust strategies to accelerate the improvement and deployment of technologies that can enable a global transition to sustainable and equitable energy systems. His approach relies on collecting and curating large empirical datasets from multiple sources and building data-informed models. His work informs research and development, public policy, and financial investment.

Dr. Ziegler conducted postdoctoral research at the Institute for Data, Systems, and Society at the Massachusetts Institute of Technology. At MIT, he evaluated established and emerging energy technologies, particularly energy storage. To determine how to accelerate the improvement of energy storage technologies, he examined how rapidly and why they have changed over time. He also studied how energy storage could be used to integrate solar and wind resources into a reliable energy system.

Dr. Ziegler earned a Ph.D. in Chemistry from the University of California, Berkeley and a B.S. in Chemistry, summa cum laude, from Yale University. In graduate school, he primarily investigated dicopper complexes in order to facilitate the use of earth-abundant, first-row transition metals in small molecule transformations and catalysis. Before graduate school, he worked in the Climate and Energy Program at the World Resources Institute (WRI). At WRI, he explored how to improve mutual trust and confidence among parties developing international climate change policy and researched carbon dioxide capture and storage, electricity transmission, and international energy technology policy. Dr. Ziegler was also a Luce Scholar assigned to the Business Environment Council in Hong Kong, where he helped advise businesses on measuring and managing their environmental sustainability.

Dr. Ziegler is a member of AIChE and ACS, and serves on the steering committee of Macro-Energy Systems. His research findings have been highlighted in media, including The New York Times, Nature, The Economist, National Geographic, BBC Newshour, NPR’s Marketplace, and ABC News.

yiyi.he@design.gatech.edu

Yiyi He is an assistant professor in the School of City and Regional Planning (SCaRP) at the College of Design at Georgia Tech. Her research centers on the interdisciplinary fields of urban planning, GIScience, climate science, and artificial intelligence. She is interested in building a better understanding of the uncertainty and asymmetric impacts of climate-change-induced extreme weather events (e.g., flooding, wildfires, extreme heat) on critical components of the built environment (e.g., lifeline infrastructure networks, vulnerable neighborhoods). She leverages data-driven approaches, such as GIS, network science, hyperspectral remote sensing, machine learning, and spatial statistics to tackle complex challenges in climate change and resilience research and to inform more intelligent planning and policy directives.

Her previous work involves using 3D hydrodynamic flood models to simulate flooding under different climate change scenarios and analyze the impact of both coastal and inland flooding on critical infrastructure networks. She received her bachelor’s degree from Nanjing University and her master’s and Ph.D. degree from UC Berkeley.
