Dr. Thomas Theis is Associate Professor of Chemistry and Physics, and Goodnight Distinguished Scholar in Molecular Characterization at North Carolina State University. His research is focused on hyperpolarization technology and unconventional NMR and MRI detection schemes. Dr. Theis was born in Heidelberg, Germany, raised in Tenerife, Spain, and completed his undergraduate and masters at the Georg-August University of Goettingen (Germany). Theis received his PhD in 2012 from UC Berkeley (USA) working with Prof. Alexander Pines on "zero-field NMR" and “parahydrogen hyperpolarization schemes for portable NMR". Dr. Theis conducted postdoctoral research at Duke University (USA) with Prof. Warren Warren focused on "singlet states for hyperpolarization storage", and worked on "low-field NMR" as visiting fellow at RWTH Aachen University with Prof. Stephan Appelt (Germany). In 2015, he was promoted to Research Assistant Professor at Duke University developing “cost-efficient hyperpolarization techniques for molecular imaging”. Since 2018, Dr. Theis leads the NC State Hyperpolarization Laboratory at NC State University where he was promoted to Associate Professor in 2023 and received the Goodnight Distinguished Scholarship. He has received numerous awards in recognition of his research including the Friedrich-Wilhelm-Bessel Award from the Humboldt Foundation and the Ampere Prize for Rising Stars in Magnetic Resonance.
