Karel Kletetschka

Graduate Researcher

Karel received a Bachelor of Science degree in Chemistry from Penn State University in 2015. He started his Master’s degree in Geosciences in the fall of 2016 at Virginia Tech, working with Dr. F. Marc Michel.

Topics of interest include iron (oxyhydr)oxide nanominerals and their nucleation, growth, and transformation in aqueous systems. Specific areas of interest include schwertmannite crystal growth, acid mine drainage, and the transport of environmental contaminants. Previous work has focused on the synthesis and transformation of colloidal nanoparticles and the development of an overarching synthesis framework for inorganic nanomaterials.
