Faculty News
Research:
Dr. David Broniatowski (EMSE) is a co-principal investigator on the grant “Improving Antibiotic Stewardship: The Role of Communication in Patient Expectations and Attitudes.” This is a one-year, $40,000 GW Cross-Disciplinary Research Fund grant, and it will support an EMSE student to conduct research on how Yelp reviews affect antibiotic prescribing. The principal investigator is Dr. Monique Turner (School of Public Health). Separately, Dr. Broniatowski received a three-month, $15,000 award—the first in what is intended to be a series of funding installments—to work on DARPA's D3M (data-driven discovery of models) program. He is a subcontract on the grant to Parenthetic, LLC.

 

Dr. Erica Gralla (EMSE) is co-principal investigator with Dr. Carlos Santos-Burgoa (School of Public Health, principal investigator), Dr. Mona Atia (Elliott School of International Affairs), and Dr. Amira Roess (School of Public Health) on the grant “Are the poor most likely to die? Spatial patterns of excess mortality and poverty following natural disasters.” The $40,000, one-year grant is funded by GW’s Cross-Disciplinary Research Fund program.

 

Dr. Ekundayo Shittu (EMSE) is the principal investigator on a four-year, $499,991, National Science Foundation grant titled “INFEWS: Quantifying complex adaptive FEW systems with a coupled agent-based modeling framework.” Dr. Shittu will work with his collaborators at University of Houston and Lehigh University to develop a new mathematical modeling framework to decipher the complex, adaptive food-energy-water system of systems (FEWSoS). The proposed modeling framework will center on an agent-based representation of the linkages among food, energy, and water sub-systems and between human and physical systems across multiple temporal and spatial scales. Under this funding mechanism, collaborators from Tsinghua University in China will also receive equivalent funding. The teams will test the utility of the developed FEWSoS modeling framework over two international river basins in the U.S. (Columbia River) and China (Mekong River) to elucidate similarities and differences in these FEWSoS and to generate new understanding that is transferable to other river basins. GW’s share of the grant is $139,500 over two years focusing on the energy sub-system.

 

Dr. Ekundayo Shittu (EMSE) also has been awarded a one-year, $30,084 Duke Energy Renewables grant for his project “Evaluating the Ecosystem of Microgrids in the Arctic and Developing Countries.” The project will contribute to “Lighting Africa,” a joint initiative of the World Bank and the International Finance Corporation, by exploring a variety of adaptive technology choices that are specific to the arctic and developing countries in tandem with the local absorptive institutional capacities. Approximately 1.2 billion people worldwide lack access to electricity; and more than half of the world’s total un-electrified population live in Sub-Saharan Africa. Separately, Dr. Shittu, Dr. Saniya LeBlanc (MAE), and Dr. Amira Roess (School of Public Health) have been awarded a follow-on one-year, $37,571 GW Cross Disciplinary Research Fund grant for their project “Improving Healthcare Intervention with Local Access to Electricity in Least Developed Countries.” Mobile devices can facilitate reporting within the health care system when disease outbreaks occur in the developing world. Unfortunately, inability to power these mobile devices is an enormous challenge faced by healthcare workers. The interdisciplinary team is working to characterize healthcare workers’ use of mobile devices, developing a prototype solution to provide locally-sourced electricity and conducting field testing to iterate on prototype design.
