Research Interests
​My research interests have focused on gravitational physics, stellar astrophysics, nonlinear dynamics, and chaos.
​
More than a decade ago, I was watching a documentary regarding Einstein's Special and General Theories of Relativity. As the concept of time dilation was being explained, I felt for the first time in my life that there were things in the universe that completely go against our everyday conceptions of reality.
​
Since then, I have been drawn to problems that involve challenges to our intuitions. These have ranged from chaos theory conflicting with ideas we may have of determinism, the complicated formation routes of high mass stars, to alternative approaches to gravity such as Conformal Gravity.
​
As I continue my career as a researcher, I wish to tackle problems in gravitational physics. Specifically, I am drawn to problems relating to black holes, cosmology, and the foundations of our understanding of gravity.
​
I believe that physics is in a state of crisis with the need to adequately explain flat galactic rotation curves, the accelerating expansion of the universe, the cosmological constant problem, among others. Rather than this crisis being a reason to be discouraged, I believe, as the philsopher of science Thomas Kuhn would, that this is a prime time for creativity and unique approaches to these problems.
​
I am thus also interested in the philosophy of science and physics. I believe that it is our responsibility as scientists to constantly engage with a meta-analysis of how research is conducted and be critical of how we understand the theories we work with on a daily basis.
