  • PhD, University of Michigan, Ann Arbor, 2008

Research Interests

Dr. Ruan’s research interests includes medical imaging,
tomography, parametric and nonparametric estimation, dynamic systems, and
general inverse problems in medical signal processing. Her current works focus
on physics system modeling and characterization, algorithm development and
performance analysis, as well as software-hardware system integration and
validation. She is particularly interested in understanding the mathematics and
physics in diagnostic radiology and radiation oncology.
