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"
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 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
- 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.
