William Thacker, Ph.D.

Professor; Department Chair


Education

Ph.D. in Physics, University of Colorado-Boulder
M.S. in Physics, University of Illinois, Urban

Research Interests

Thacker’s research interests include theoretical physics, theory and modeling of turbulence. Focus of current research includes:

  • Foundations of quantum mechanics and quantum information theory turbulence in time-dependent mean flows
  • The influence of compressibility on turbulent correlations involving pressure development of turbulence models that incorporate transition
  • Probability density functions for turbulence and for chaotic advection
  • Theory of chaos and dynamical systems
