Dr. Qiu is particularly interested in discovering the kind of new knowledge that brings physics to biology. He has started at the molecular level and worked from bottom up on biomolecules of increasing complexity. Developing faithful physical models and refining them with experiments have been the staples of Dr. Qiu's research. His research has spanned all families of biomolecules from nucleic acids to protein to lipids, and the primary techniques in the lab are x-ray and neutron scattering, force measurements, biophysical modeling, and deep learning.
