Short Bio:

Dr. Andreas B. Schmidt received his PhD in Physics from the University of Freiburg, Germany, where he developed a novel parahydrogen-based technique for liquid-state nuclear hyperpolarization without a polarizer. He holds a diploma in Physics from the same university and spent a year studying abroad at Universidad Complutense Madrid, Spain. He also holds a Master in Public Management from the University of Applied Sciences Kehl, Germany.

Dr. Schmidt is currently serving as the Head of the Hyperpolarization Group at the University Medical Center Freiburg, Germany, and as a Principal Investigator at the German Cancer Consortium partner site Freiburg. He has also held research fellowships at the University Hospital Schleswig-Holstein, Kiel, and at Wayne State University in Detroit. He is the overall coordinator of the HYPERBOLIC joint funding project within the German Cancer Consortium (DKTK), which links German research groups from Munich, Tübingen, Heidelberg, and Freiburg in their research activities on hyperpolarization. Since 2023, he is a Junior Fellow of the International Society for Magnetic Resonance in Medicine (ISMRM).

Dr. Schmidt's research focuses on parahydrogen-based polarization methods, singlet states, hyperpolarization phenomena like radio amplification by stimulated emission of radiation (RASER), and chemical shift imaging.
