Summary of Research
Data from current collider experiments agree extremely well with our existing models of fundamental interactions. This means that up to scales of about 1000 times smaller than the nucleus, we have a successful theoretical description of matter and radiation. Nevertheless, there is also significant evidence that our understanding is incomplete, and is not correct for phenomena at higher energies. Unfortunately, current technology limits the energy scales we can create, forcing us to seek other sources of guidance for building and testing theories.
Cosmology and astrophysics are sensitive to physics at many energy scales, providing an alternative method for understanding fundamental physics throughout the energy spectrum. By understanding how different theories affect the evolution of our universe and the structure within it, we can use observations as further evidence and constraints for different models.
The study of black holes is another avenue to investigating phenomena relevant at high energies. While there is reason to believe that we could apply our theoretical framework of fundamental interactions to black holes, so long as we stay in regions where gravity is weak, doing so leads to certain inconsistencies. Black holes are thus one of our primary ways of understanding how the fundamental interactions emerge from physics at very high energies.
Currently, I am investigating how the axion, an important particle in the strong interaction sector, affects the evolution of our universe, in light of recent evidence from the CMB. Another focus of my research is examining black hole evaporation to formulate a description that is free of inconsistencies, and where our current successful theories emerge as an effective description of the world. This is motivated by the recent development in black hole physics, which sharpened the information paradox first proposed by Stephen Hawking.
