While my degree is in geological oceanography, I have wide-ranging interests in physical and geochemical processes associated with volcanism in both the marine and terrestrial environments. As a faculty member at the University of Southern Indiana, my teaching efforts are focused on physical geology, igneous and metamorphic petrology, volcanology, and oceanography.
My research interests are generally related to better understanding volcanic activity. I recently completed a project with the late Jim Luhr in which we worked to characterize the pre-eruptive volatile conditions associated with Quaternary lamprophyres from western Mexico through analysis of melt inclusions trapped within olivine crystals. Our work supports a vein-wallrock melting relationship between the lamprophyres and the predominant calcalkaline andesites in this area, contributing to our understanding of the volcanism and the role of volatile-rich primary melts at subduction zones. Another interest of mine is quantitative shape analysis of volcanic particles as a means of insight to volcanic processes such as magma fragmentation and volcaniclastic transport and deposition. My efforts have focused on image-analysis based on fractal geometry, and I am convinced that sucl analysis of volcanic particles can become a valuable tool for hazard assessments of volcanic areas.
