Arturo A. Keller (PhD Stanford, 1996) is Professor of Biogeochemistry at the Bren School. He holds a joint appointment in Mechanical and Environmental Engineering at UCSB. His research and teaching interests focus on water quality management and the fate and transport of pollutants in the environment.

Dr. Keller seeks to understand the processes through which contaminants may accumulate or transform in soil, air or water, as well as in the biota, with an emphasis on developing better management strategies for dealing with pollutants in the environment. He is the Associate Director of the new NSF/USEPA funded UC Center for the Environmental Implications of Nanotechnology. Current research topics involve the treatment of water and soils which have been contaminated with nanoparticles or hazardous wastes, larger scale pollution management at the watershed scale, and the nexus between energy and water. In addition to analyzing the scientific issues involved, Dr. Keller is interested in the development of management strategies to suit the characteristics of each site, minimizing risk at least cost. Dr. Keller has had several years of experience developing management strategies in the private sector, which he brings to his Bren School courses and projects. He has been recognized three times with the Bren School Distinguished Teaching Award.

Dr. Keller is known for his involvement in the phasing out of the gasoline additive MTBE as part of a UC-wide project; his research found MTBE to seriously affect water resources while providing only modest air quality benefits relative to other alternatives.

Dr. Keller also was the facilitator for the award-winning (2003 David Nahai Water Quality Awards) Nitrogen TMDL process for the Santa Clara River. Previous TMDLs in the region had been very contentious, but through a combination of science-supported decision-making and a willingness to try out many ideas proposed by the stakeholders, the Santa Clara River TMDL Steering Committee was able to reach a consensus, which was fully supported by the RWQCB. The steering committee received the 2003 H. David Nahai Water Quality Award for their work.

Dr. Keller and his research team provided the scientific underpining to the Ohio River Water Quality Trading Program, which received the 2015 U.S. Water Prize, led by EPRI. Dr. Keller's group develop the models for the program, as well as the science for the attenuation factors.

Dr. Keller is also well-known for his expertise in the fate and transport of pollutants, including nanoparticles, organic liquids (NAPLs), and persistent organic pollutants associated with clay particles; he has over 110 peer-reviewed publications in top journals. His research team also works on technologies to solve important water-quality problems, and recently was covered in the New York Times for a major improvement in the technology to skim oil spills in marine environments, which can significantly reduce the risk of the oil spill reaching coastal resources. Recently a novel nanomaterial was developed to deal with the contamination of persistent organic pollutants, a major legacy issue. Several patents have resulted from these various projects.
