Research Experience

Graduate Student Research Assistant, University of Michigan, Ann Arbor, MI, 2008/11-2013/4

• Developed an efficient and novel methodology to detect damages in turbomachinery rotors using reduced order modeling and vibration data

• Analyzed aerodynamic effects of turbomachinery rotors using efficient reduced order modeling

• Conducted comprehensive identification of mistuned bladed disks (e.g., mistuning and damping)

• Developed bilinear amplitude approximation method for nonlinear (piecewise-linear) oscillators

• Developed nonlinear reduced order models to capture effects of Coulomb friction in combustor systems

Individual Researcher, Larson group, University of Michigan, Ann Arbor, MI, 2008/2-2008/10
