# Publications

Group member authors and alumni are bold-faced in the following list. While the convention in astrophysics is for author lists to be prioritized, many papers in both the high-performance computing and fluid mechanics literature have author lists which are either completely or partially-alphabetical. These papers are evident in context.

You may also Google MyCitations, which tracks most, but not all citations to these papers, as well as check out my ORCID iD page. Both arXiv and Pub Med Central (PMC) are public access.
