Christina Birkel

Assistant Professor
Faculty, TEMPE Campus, Mailcode 1604

Christina Birkel joined the faculty of the School of Molecular Sciences in 2019. Prior to her appointment as an assistant professor at ASU, she held an Athene Young Investigator (junior research group leader) position at the Technische Universität (TU) Darmstadt, Germany (2013-2018). During that time, she also completed her Habilitation in the Department of Chemistry at TU Darmstadt. Before her independent career, she was a postdoctoral researcher in the groups of Prof. Galen Stucky and Prof. Ram Seshadri at the University of California, Santa Barbara (UCSB, 2011-2013). At UCSB, she focused on the development of non-conventional solid-state synthesis methods to prepare (mostly intermetallic and oxide) energy (e.g. thermoelectric and phosphor) materials. She received her doctorate (Dr. rer. nat., summa cum laude) in late 2010 with a double-degree from the University of Mainz, Germany and Seoul National University, South Korea working with Prof. Wolfgang Tremel and Prof. Kookheon Char. Her graduate work involved the wet-chemical synthesis of chalcogenide nanoparticles for thermoelectric applications.

Research Activity: 

Our group focuses on a broad range of synthesis methods that we use to prepare functional inorganic materials. Our main expertise lies in wet chemical as well as classical and non-conventional (e.g. microwave heating) solid-state techniques. By means of structural (X-ray diffraction) and microstructural (e.g. electron microscopy) analyses, we investigate formation mechanisms and the influence of the synthesis conditions on the final product. We are particularly interested in the magnetic, electronic and catalytic properties of the inorganic solids.
