Songi Han

Songi Han is an American chemist who is a professor in the department of chemistry and biochemistry at Northwestern University. Her research considers electron and nuclear spins as sensors and detectors. She was elected a Fellow of the International Society of Magnetic Resonance in 2019 and president of the International EPR Society in 2020.

Early life and education
Han attended the University of Cologne as an undergraduate, where she majored in chemistry. She moved to the RWTH Aachen University, where she investigated magnetic resonance. She was awarded the Ampere Society Raymond Andrew Prize in 2002.

Research and career
Han has pioneered the use of spin based approaches (including electron paramagnetic resonance, Nuclear magnetic resonance and relaxometry, to understand the structure-property relationships of biomolecules. Her work on dynamic nuclear polarization has enabled new probes for monitoring biological processes. This allows for the mapping of surface water differences around globular proteins.
