Theoretical nuclear and particle astrophysics group
Research Field
I received my PhD degree from the University of Minnesota, USA in 2012. I was a postdoctoral fellow in the Technische Universität Darmstadt, Germany from 2013 to 2016 and in the Niels Bohr Institute, Denmark during 2016-2017. I joined the Institute of Physics, Academia Sinica as a faculty member in 2017, and is a joint fellow in the Institute of Astronomy and Astrophysics, Academia Sinica as well as a Center Scientist in the Physics Division of the National Center for Theoretical Sciences.
My research interests span a wide range in the fields of nuclear astrophysics and particle astrophysics, with particular focus on the nucleosynthesis of heavy elements, neutrino flavor conversions in dense media, production of hign-energy neutrinos in stellar explosions, and probing physics beyond the Standard Model with astrophysics.
Physics laws and principles dictate how the Universe evolves -- from the sub-atomic scale to the cosmological scale. Physicists working at different subjects are devoted to the goal of finding the most fundamental properties of matter, including what they are and how they interact. In our group, we seek to find answers to questions related to physics at the extreme -- conditions that we cannot replicate inside the laboratories. To this aim, we look at some of the most violent astrophysical phenomena over the sky, to understand how physics work therein and how they happen.
Questions that we are focusing to find answers now include:
- How are where are the known elements made in the Universe?
- How do neutrinos, particles that interact weakly with matter, behave (interact and oscillate) at dense environments where they are trapped?
- Can we find signature of physics beyond-the-Standard-Model with astrophysical messengers?
- What are the astrophysical sources of making the most energetic particles in the Universe?
Through theoretical and computational studies, we aim to compare what we find with observations to help answer these questions.
Specific research topics include:
- Modeling neutrino flavor oscillations in stellar explosions and study their implications.
- Investigating the production of heavy elements in stellar explosions.
- Modeling production of high-energy neutrinos in stellar explosions.
- Formulating novel methods to probe physics beyond the Standard Model with astrophysical observations.
