Kai Loon Chen is an Assistant Professor in the Department of Geography and Environmental Engineering at Johns Hopkins University in Baltimore, Maryland. He completed his B.Eng. and M.Eng. degrees in civil engineering at the National University of Singapore in 2001 and 2003 respectively. He joined the Environmental Engineering Program at Yale University in 2003 and received his Ph.D. in 2008. His current research focusses on understanding the fate and transport of engineered nanoparticles in natural and engineered aquatic systems. He is also interested in utilising nanotechnology for water purification and environmental remediation.

Billy A. Smith is a graduate research assistant pursuing his doctorate in Chemistry in the research group of Professor Howard Fairbrother, Johns Hopkins University (JHU), Baltimore, Maryland. He earned his B.S. in chemistry from Stevenson University (previously known as Villa Julie College) in 2005, and currently holds a masters degree in Chemistry from JHU. In the Fairbrother group, he has used surface analytical techniques in conjunction with time-resolved dynamic light scattering to study the role that oxygen containing functional groups play in determining the colloidal stability and transport properties of oxidised carbon nanotubes.

William P. Ball (P.E., Ph.D., BCEE) is a Professor of environmental engineering in the Department of Geography and Environmental Engineering at Johns Hopkins University. He received his B.S. from the University of Virginia in 1976 and his M.S. and Ph.D. in environmental engineering from Stanford University in 1977 and 1989. Between his M.S. and Ph.D., Professor Ball worked for six years for James M. Montgomery Consulting Engineers. He was previously on the faculty at Duke University and in 1992 joined the faculty at Johns Hopkins University. Professor Ball’s research program is focussed on physical and chemical processes affecting pollutant fate and treatment in natural environments and engineered systems, with focus on complex aquatic systems.

D. Howard Fairbrother is a Professor of Chemistry at Johns Hopkins University in Baltimore, Maryland. He received his B.S. degree from Oxford University, England, in 1989, and his Ph.D. in chemistry from Northwestern University in 1994. After completing a postdoctoral position with Professor Gabor Somorjai at the University of California, Berkeley, he joined the faculty in the Chemistry Department at Johns Hopkins University (JHU) in 1997. His research program at JHU is focussed on surface chemistry, with particular emphasis on characterising the functional groups on environmentally relevant materials and understanding the role of surface chemistry on the behaviour of engineered nanomaterials in aquatic environments.
