R.K.M. Jayanty

Distinguished Fellow, Environmental Analytical Chemistry

R.K.M. Jayanty, PhD, is a leading expert in environmental analytical chemistry and the senior program director of environmental and industrial sciences at RTI. He has more than 40 years of experience in environmental analytical chemistry, including significant program management and technical experience with complex multimedia sampling and analysis, chemical speciation, and method development/evaluation of programs for air toxics and fine particles. Dr. Jayanty’s technical experience includes methods development, evaluation, and field validation studies related to the measurement of toxic organics and fine particulates in ambient and source atmospheres. He is currently program manager of the chemical speciation of PM2.5 filter samples collected through nationwide network operations, and is an adjunct professor in the Department of Biological and Agricultural Engineering, College of Agriculture and Life Sciences, North Carolina State University. Dr. Jayanty is an internationally recognized scientist and the author of more than 150 technical papers, reports, and presentations.
