Bio

Dr. Garoma is a Professor in the Department of Civil, Construction and Environmental Engineering. He is the Blasker Chair in Environmental Engineering and the Director of the Environmental Engineering Program. Currently he serves as the Associate Dean for Graduate Studies and Research in the College of Engineering. He completed a Ph.D. degree in Engineering Mechanics (Environmental Engineering) from the Joint Doctoral Program between the University of California, San Diego and San Diego State University in 2004. He received a B.S. degree in Civil Engineering from Addis Ababa University, Ethiopia and an M.S. degree in Geotechnical Engineering from University of Hannover, Germany.

Education

PhD - Environmental Eng., University of California-San Diego and San Diego State University, 2004

MSc - Geotechnical Eng., University of Hannover, 2000

BSc - Civil Eng., Addis Ababa University, 1996

Areas of Specialization

The emphasis of Dr. Garoma’s research is on water and wastewater treatment, resource recovery, and renewable energy. His current research focus is on biofuels production from algal biomass, resource recovery from wastewater and integration of wastewater treatment with energy production. In the past, he served as the principal investigator on several research projects that focused on the application of advanced oxidation processes and the formation of disinfection byproducts during ozonation and chlorination of drinking water and wastewater effluents.
