Research Group

Postdoctoral Researcher

Dr. Janet Arras (since 01/2019)
Janet graduated from Eberhard Karls University of Tübingen in 2009 (Diplom, equivalent to M.S.) and earned her doctoral degree in the field of inorganic synthesis and coordination chemistry with Prof. Lars Wesemann in 2013. She subsequently joined the group of Prof. Christian Ochsenfeld at Ludwig Maximilians University of Munich as a postdoctoral researcher in computational chemistry. After an interim appointment in industrial research and development, Dr. Arras accepted a combined research position in 2017 as a project leader in Prof. Stefan Bräse’s group (photoluminescent materials) and as a postdoc with Prof. Hansgeorg Schnöckel (base metal cluster chemistry), both at Karlsruhe Institute of Technology (KIT). In January 2019, Janet moved to the U.S. to join the Stollenz Group as KSU's first full-time postdoctoral research scientist in inorganic/synthetic chemistry. She is interested and trained in various fields of organic and inorganic synthesis, coordination chemistry, crystallography, photoluminescent materials, and computational chemistry.

Graduate Researcher (M.S.)

Keri Dowling, B. S. (master thesis since 08/2021)


Keri is originally from Charlotte, NC, but relocated to Marietta, GA with her husband and daughter in the summer of 2020. She earned her Bachelor’s in Chemistry from UNC Charlotte, where she worked in both physical and inorganic chemistry labs, with focuses on spectroscopic analyses of hybrid gold nanoparticles and gold nanorods, and the coordination chemistry of expanded ring N-heterocyclic chalcogenones. Keri enjoys mentoring new students and helping them cultivate their skills as researchers. She hopes to one day teach inorganic chemistry at the university level. Outside of a lab space, she enjoys competitive fast chess and hobbyist mycology.
