Brennan Gardner Rivas and Joseph Stoltz, who both served as postdoctoral researchers, have accepted new positions that build on their work with CSGS.
Rivas, who was a senior postdoctoral researcher and associate director for CSGS, was named the new associate director of the Clements Center for Southwest Studies at Southern Methodist University in May 2026. She was the lead researcher for the team working on “Firearms use and regulation in the 18th and 19th centuries: Modeling the Application of Historical Methods for Law and Policy in the Bruen Era.”
Stoltz, who was a digital humanities postdoctoral researcher for CSGS, was named as the new senior director of education at Fort Ticonderoga in upstate New York. During his time with CSGS, he collaborated with Rivas and a designer to create an innovative website for the research project. The site will be released later in 2026.
