Christian Wallen

Christian Wallen is an Assistant Professor in the Department of Chemistry and Fermentation Sciences at Appalachian State University, where he joined the faculty in 2020. He teaches Introductory and Inorganic Chemistry and mentors undergraduate researchers in his laboratory.

Education:

• Ph.D. in Chemistry, Emory University (2017)
• B.S. in Chemistry, Union University (2012)

Research Interests: Dr. Wallen investigates the coordination chemistry of hydrogen sulfide ($$\text{H}_2\text{S}$$) and hydrogen peroxide ($$\text{H}_2\text{O}_2$$) with transition metals. His work spans environmental applications (e.g., natural gas treatment) and biological modeling (e.g., hydrogen sulfide signaling). Students in his lab develop skills in air-sensitive synthesis and spectroscopic characterization.

Publications Trend: His recent publications (2015-2021) demonstrate expertise in small molecule activation by transition metals, with emphasis on second-sphere hydrogen bonding effects and catalytic applications in energy and environmental contexts.

Advising: Dr. Wallen actively mentors undergraduate students in research, emphasizing hands-on training in inorganic synthesis and analysis.

Research Laboratory: He maintains an active research group studying transition metal complexes for small molecule activation at Appalachian State University.
