Karl Mueller, a physical chemist, focuses on the development and utilization of solid-state nuclear magnetic resonance (NMR) techniques, and his most recent studies are driven by outstanding and unresolved questions in materials and environmental science that require advanced characterization tools and multi-disciplinary/multi-modal approaches.

Dr. Meuller’s current research interests include discovering molecular-level details of fundamental reactions in the environment (such as dissolution of minerals and glasses), as well as the coupling of soil/mineral weathering to the fate of radionuclides under harsh geochemical conditions at chemical waste sites. Dr. Mueller and his research team are also studying the transport of conducting species in new lithium battery materials as part of the Joint Center for Energy Storage Research (JCESR), where he is also the Lead Scientist for Cross Cutting Science.

He was a Postdoctoral Research Fellow at the University of British Columbia from 1991 to 1993. Dr. Meuller joined Penn State University in 1993 and served as: Assistant Professor until 1999; Associate Professor from 1999 to 2007; and Professor from 2007 to 2016 (now adjunct). He was a member of PNNL’s Environmental Molecular Sciences Laboratory’s  User Advisory Committee from 2007-2010. Dr. Meuller joined EMSL in August 2010 as a Laboratory Fellow.

He has authored or co-authored more than 110 publications. Dr. Meuller is a member of the American Association for the Advancement of Science, American Chemical Society, Materials Research Society, and the Electrochemical Society.

Dr. Meuller has been recognized as: Fellow of the American Association for the Advancement of Science, 2012; University of Ottawa Varian Lecturer, 2007; Alfred P. Sloan Research Fellowship, 1999; Camille Dreyfus Teacher Scholar Award, 1997; Research Corporation Cottrell Scholar, 1996; Arnold and Mabel Beckman Foundation Young Investigator Award, 1996; National Science Foundation Young Investigator Award, 1994; Camille and Henry Dreyfus New Faculty Award, 1992; and member of external review panels for National Science Foundation and U.S. Department of Energy.

Dr. Meuller received his B.S. in Chemistry (summa cum laude) from the University of Rochester in 1985, his Certificate of Post Graduate Studies from Cambridge University in 1986, and his Ph.D. in Chemistry, University of California, Berkeley in 1991.
