These processes are fundamentally linked to magmatism and the formation of ductile shear zones, which play a critical role in crustal deformation. My research focuses on understanding these mechanisms by integrating petrology, structural geology, and geochronology—a methodology I describe as structural petrochronology.</span></p><p class="MsoNormal" style="margin: 0in; font-size: medium; font-family: "Times New Roman", serif;"><span style="font-family: "Calibri Light", sans-serif; text-indent: 0.5in;"><span class="Apple-tab-span" style="white-space: pre;"> </span>I investigate the timing and role of magmatism, metamorphism, deformation, and exhumation in crustal evolution, with a particular emphasis on high-temperature ductile shear zones and magmatic systems. Key contributions include characterizing melt storage and emplacement in silicic magma systems, developing titanite petrochronology to directly date deformation in shear zones, and studying water-assisted grain boundary migration in quartz to better understand ductile behavior. My work has provided insights into the spatial and temporal evolution of strain localization, the feedback between magmatism and deformation, and intra-arc transpression in the North American Cordillera.</span></p><p class="MsoNormal" style="margin: 0in; font-size: medium; font-family: "Times New Roman", serif;"><span style="font-family: "Calibri Light", sans-serif;"><span class="Apple-tab-span" style="white-space: pre;"> </span>Future research aims to expand these approaches to the southern North American (Peninsular Range batholith, Mexico) and South American Cordilleras (Miocene plutonic belt, Chile) to address fundamental questions about deformation processes, magma emplacement, and plate reconstructions. Through interdisciplinary collaborations and community engagement, I seek to advance our understanding of the dynamic processes shaping Earth's lithosphere.</span></p><p class="MsoNormal" style="margin: 0in; font-size: medium; font-family: "Times New Roman", serif;"></p></body></html>
