I work primarily on computational nuclear astrophysics. My research interests include compact objects, astrophysical sources of gravitational waves, and core-collape supernovae. Below I will talk about some of my past and future efforts in these different interests. A complete list of my scientific publications can be found here. For more information, please see my CV.

Massive Stars

3D volume rendering of a massive star moments before iron core-collapse.

In Fields & Couch (2020), we investigated the three-dimensional evolution of a 15 solar mass star for the final seven minutes up to and including iron core-collapse. In this work we found that 1D models of massive stars may estimate convective speeds by a factor of four less than our 3D models suggest. These results have crucial implications for models of core-collapse supernova explosions.

Spearman Coefficient for 8 stellar properties against 665 nuclear reactions.

In Fields et al. (2018), we investigated impact of nuclear reaction rate uncertainties on the evolution of core-collapse supernova progenitors. We found that reaction rates can have crucial and qualitative impact on the evolution of the stellar models leading to progenitors that vary up to 30-40% as they near iron core-collapse.

3D volume rendering of entropy during the explosion fo a 15 solar mass using a 3D progenitor model.

In Fields & Couch (2020), we investigated impact of using a three-dimensional supernova progenitor on the impact of the predicted multi-messenger signals.
