Antoine de Saint Exupéry once wrote:

"Perfection is achieved, not when there is nothing more to add, but when there is nothing left to take away."

This is an idea I embrace in my research. I try to find minimum models that include the fewest possible parameters and physical processes while still reproducing observed phenomena. Minimum models allow us to draw a clear connection between phenomena and physical processes. This is especially important in complex systems where numerous processes compete and influence each other. My research concentrates on one such process: star formation, which is one of the key processes of cosmic evolution as it influences phenomena from the formation of galaxies to the formation of planets, and the development of life.

Some of the questions in star formation I am trying to answer:

  • What regulates SF?
  • What sets the characteristic mass of stars?
  • Why are stars clustered?
  • How is SF different in other galaxies?
Ph 2 abc. Waves, Quantum Mechanics, and Statistical Physics. 9 units (3-0-6); first, second, third terms. Prerequisites: Ph 1 abc, Ma 1 abc. An introduction to several areas of physics including applications in modern science and engineering. Topics include discrete and continuous oscillatory systems, wave mechanics, applications in telecommunications and other areas (first term); foundational quantum concepts, the quantum harmonic oscillator, the Hydrogen atom, applications in optical and semiconductor systems (second term); ensembles and statistical systems, thermodynamic laws, applications in energy technology and other areas (third term). Although best taken in sequence, the three terms can be taken independently. Instructors: Martin, Politzer, Cheung, Filippone.
