Research & Teaching Interests
       I love science. Astronomy and physics are my passion. (I admit to flings with earth science, computer science, biology, chemistry and off course literature, philosophy and poetry.) I want to do as much science as I possibly can through scholarship, outreach, and teaching. I also work as the academic director of a program called "The Summer Science Program" in Ojai, California. That is the oldest, and best, summer program for astronomy in the country. Check it out!

My research interests in:


  • Black Hole Candidates: I want to know what makes quasars and black hole `tick,' and what use we may find for the physics of matter near black hole candidates.  I am trying to apply that knowledge to the study of high temperature plasmas and  shock waves in plasmas.
  • Non-linear Dynamics in Astrophysics: The above systems are perfect labs for studying non-linear dynamical systems in astrophysics. Non-linear dynamics and time series analysis may be referred to as the quantitative study of how things tick.
  • Cosmology: I am working on a back - reaction model of post-recombination cosmology that will explain the recently observed apparent acceleration of the universe. Again, non-linear dynamics plays a role. For more on my research click here.

Physics and Physics Related:

  •  Physics of Shatter Cones: Recently I started to work with Prof. John Weber and his Earth & Space science students, on trying to understand shatter cones in ancient impact craters. This project combines knowledge of shocks and elasticity with John's expert knowledge of geology. Its a fun project!
  •  Physics Education: I also wants to know what makes science students `tick', so I do physics and astronomy education research. I developed new methods of teaching, and  alternative explanations to many "rules of thumb" in physics.
