Dr. Sybil Sharvelle, Center Director
Dr. Sharvelle has nine years of experience working on graywater projects. Her graduate studies were funded by NASA to optimize biological waste processing systems that would treat graywater with the end goal of potable reuse. The waste treatment concept employed entailed separate source collection and treatment of graywater, urine, and fecal material. Dr. Sharvelle’s experience in closed loop recycling of resources is very valuable for implementation of sustainable development concepts for urban water management. Dr. Sharvelle is currently working on sustainable urban water management including graywater reuse, reclaimed water reuse, development of models to estimate water savings associated with urban water conservation practices. Dr. Sharvelle also has several years of experience working on waste conversion to methane through anaerobic digestion.
Dr. Larry Roesner
Dr. Roesner joined CSU as the endowed Harold S. Short Chair of Civil Engineering Infrastructure Systems in 1999. His research at CSU is focused on improving urban water management, particularly through studying residential graywater reuse and improved urban drainage techniques to protect receiving water quality. Prior to joining CSU, Dr. Roesner assumed roles as Vice President and Technical Director of Water Resources while working for the consulting firm Camp, Dresser and McKee for nearly 25 years.

Dr. Neil Grigg
Dr. Grigg has experience in urban water and utility management as a researcher, consulting engineer, state official, and member of local boards. His recent emphasis has been on management and on distribution systems infrastructure. His published book titles include Water and Sewer Infrastructure Management (second edition) and Urban Water Infrastructure, along with other books on water and infrastructure engineering and management. His recent research has focused on water main failures, risk analysis, and water efficiency in cities.

Dr. Mazdak Arabi
Dr. Arabi is an associate professor of Civil and Environmental Engineering at Colorado State University. His research is primarily focused on development of decision support systems for management of water resources at the watershed scale. To make informed decisions, policy makers should have the tools necessary to identify areas that are most vulnerable to erosion and contaminant transport, and subsequently assess tradeoffs between environmental and economic impacts of management actions. Dr. Arabi has developed and demonstrated optimization-based approaches to facilitate development of watershed management plans that achieve water quality goals at significantly lower costs. He has published analytical and computational methods to support both deterministic and probabilistic evaluation of watershed-scale benefits of best management practices.

Chris Olson, P.E.
Chris is the Program Manager for the Colorado Stormwater Center at Colorado State University where he develops and conducts urban stormwater-related education and training for a variety of audiences. Chris is also a doctoral canditate in Civil and Environmental Engineering at CSU where he conducts research on design, monitoring, performance evaluation and modeling of stormwater best management practices. Chris has an M.S. in Civil Engineering from CSU and a B.S. in Environmental Engineering from the University of Wisconsin-Platteville. Prior to returning to graduate school at CSU, Chris worked as a water resources engineering consultant in California.
