Dr. Mattigod earned his Ph.D. in Environmental Chemistry from Washington State University and his M.S.and B.S. degrees in Civil Engineering from the University of New Hampshire and University of Mysore, respectively. After serving on the faculty at the University of California, he joined Battelle–Pacific Northwest Division in 1986. Since then, he has led and participated in a number of projects related to the development of novel technologies for treating radioactive liquid and solid effluents, leachates, RCRA wastes, and contaminated soil and groundwater from CERCLA sites. During the past decade, he has focused on developing a novel adsorption material (self-assembled monolayers on mesoporous silica supports, or SAMMS) to remove heavy metals and oxyanions from waste streams and contaminated groundwater. His more than 170 publications include journal articles, book chapters, and technical reports.
