PROFESSIONAL INTERESTS

Dr. McNulty’s geological research was funded by five National Science Foundation (NSF) grants. The NSF-funded projects primarily centered on the evolution of continental magmatic arcs, the mechanics of pluton emplacement, the pressure-temperature-time development of ductile shear zones, and the formation of pseudotachylyte. The research was conducted in North America (Sierra Nevada, California), South America (Cordillera Blanca, Peruvian Andes), and Asia (Qinling Mountains, Shaanxi Province, China), and featured in top geology journals (cover photos below from Geology and GSA Bulletin). The work in Peru led to the CSUDH Award for Outstanding Research in 2006.

McNulty subsequently focused on environmental issues, including a collaborative project with Dr. Weixing Tong (Los Angeles Water Board). Their work centered on training undergraduate and graduate students in hydrogeology, with a specific focus on the contamination of groundwater by gasoline oxygenates (notably MTBE: methyl tertiary-butyl ether). This project - funded by the NSF’s Opportunities for Enhancing Diversity in the Geosciences (OEDG) program - provided students hands-on experience with a "real world" environmental problem, financial support while attending college, and training that led to jobs. 

McNulty also collaborated on several externally funded projects focused on K-12 science teacher education (NSF-Urban Systemic Initiative; NASA-ALERT; Los Angeles Annenberg Math–Science Literacy Project). His latest work centers on developing field trip guides for non-geologists.
