KJ Reddy (Katta Jayaram Reddy)

George Duke Humphrey Distinguished Professor of Ecosystem Science and Management
Adjunct Professor of School of Energy Resource
Visiting Research Scholar, Physics Department, Harvard University

Area(s) of expertise:

  • Geochemistry of Water
  • Environmental Chemistry
  • Water Quality

Professor KJ Reddy studies natural resources issues that pose major challenges to maintain sustainable environment. His research goals are to 1) develop a viable solution to millions of people around the world suffering from arsenic contaminated drinking water, 2) develop effective point-source carbon dioxide (CO2) mineralization technology to become a part of the solution to the climate change problem, and 3) create beneficial uses for produced water generated from energy resource extraction and energy production processes.


K.J. Reddy distinguished scientist and professor was born in India. He received his Bachelor of Science and Master of Science degrees from India. He received his Ph.D. in Environmental Quality in 1986 from Colorado State University. He worked as post-doctoral fellow from 1986-1990 at Department of Geology and Geophysics, University of Wyoming (UW). He worked as a Research Scientist at UW Water Research Center from 1990-2000. In 2000 Dr. Reddy joined the Department of Ecosystem Science and Management as an assistant professor and was promoted to full professor in 2005. From 2000-2010 he served as a Director for UW campus-wide Water Resources Interdisciplinary Graduate Degree Program. He also served as a Deputy Director for UW School of Energy Resources from 2008-2010.

Professor Reddy is world-renowned scientist for his pioneering work on mineralization of anthropogenic flue gas CO2, filtration of toxic arsenic species from water, and geochemistry and beneficial uses of coalbed natural gas (CBNG) produced water. His high impact research programs have spread beyond the scientific community to be featured in a variety of high visibility news and print media from local to global levels. He has given several invited presentations at international conferences and workshops held in nineteen different countries. He holds 10 patents [4 US and 6 international: Australia (2), Japan (1), Mexico (1), New Zealand (1), and Philippines (1)]. Currently he is working on intrinsic properties of nanoparticles with engineers, economists, and medical scientists to develop sustainable solutions for emerging environmental issues such as climate change, global health crisis from arsenic contamination of groundwater, and optimum uses for produced water associated with different energy production processes.
