Professor
Director, Ka Moamoa – Ubiquitous and Mobile Computing Lab
BBISS Lead: Computational Sustainability

Josiah Hester works broadly in computer engineering, with a special focus on wearable devices, edge computing, and cyber-physical systems. His Ph.D. work focused on energy harvesting and battery-free devices that failed intermittentently. He now focuses on sustainable approaches to computing, via designing health wearables, interactive devices, and large-scale sensing for conservation. 
   
His work in health is focused on increasing accessibility and lowering the burden of getting preventive and acute healthcare. In both situations, he designs low-burden, high-fidelity wearable devices that monitor aspects of physiology and behavior, and use machine learning techniques to suggest or deliver adaptive and in-situ interventions ranging from pharmacological to behavioral. 
   
His work is supported by multiple grants from the NSF, NIH, and DARPA. He was named a Sloan Fellow in Computer Science and won his NSF CAREER in 2022. He was named one of Popular Science's Brilliant Ten, won the American Indian Science and Engineering Society Most Promising Scientist/Engineer Award, and the 3M Non-tenured Faculty Award in 2021. His work has been featured in the Wall Street Journal, Scientific American, BBC, Popular Science, Communications of the ACM, and the Guinness Book of World Records, among many others.

    Principal Research Scientist
    Manager, Energy and Sustainability Research Program

    Mr. Caravati is a Principal and Founder of Applied Plasma Arc Technologies, LLC and a Senior Research Scientist and Professional Geologist at the Georgia Tech Research Institute (GTRI), the applied research arm of the Georgia Institute of Technology. He received his Bachelor’s degree in Geology from the University of Dayton, Ohio, and a Master of Science in Geology-Hydrogeology track from the University of South Florida in Tampa, Florida. He earned a Master’s degree in Business Administration (International Business) from the Stetson School of Business and Economics at Mercer University in Atlanta. He began work with GTRI in 2002.

    Mr. Caravati served as a Hydrogeologist, Project Manager, and Project Director for a wide range of water resources and water quality projects in the United States, Mexico and England. He has led numerous water resource investigations that included delineating watersheds using aerial imagery and GIS tools, well installation and testing programs, monitoring and field data collection programs, and developing ground water flow and contaminant transport models for predictive studies. Since 2008, he served as Director of the Environmental Safety and Occupational Health Programs at GTRI, and as Program Manager for environmental engineering research for a global services provider. Mr. Caravati also served as a research lead in Georgia Tech’s Plasma Arc Research Facility. 

    Mr. Caravati’s areas of research include the design and prototyping of dry sanitation systems; testing of chemical and biological sensor systems for environmental applications; modeling of renewable energy systems for rural areas; water supply and wastewater studies for sustainability and energy efficiency; and water resource investigations for rural watersheds in developing countries. He serves as a Research Advisor to Georgia Tech’s Engineering Students Without Borders chapter, and in 2007 he led or participated in projects in Angola, Bolivia, and Yellowstone National Park, and served in an advisory capacity for projects in Kenya, Japan, Korea, Guam, and Ireland.

    As Director of Activities for three of Tech's Interdisciplinary Research Institutes: the Strategic Energy Institute, the Renewable Bioproducts Institute, and the Brook Byers Institute for Sustainable Systems, I'll help bring together researchers from different disciplines to address topics of strategic importance. Each interdisciplinary research group mobilizes faculty to address the needs of external stakeholders (federal, state, and local entities, corporations, foundations, and communities) by fostering an Institute-wide innovation ecosystem around a specific focus.
