Research Interests
My research explores the architecture of orogeny at multiple spatial and temporal scales. My aim is to integrate rheology, petrology, and paleotopographic reconstructions to explore the source and role of water in the strength of the mid crust, as well as what drives the transition from relief building to tectonic destabilization. I focus on three main themes throughout my work: 1) quantification of rheologic response to fault-fluid interaction across geologic history, 2) paleoaltimetry and direct proxies for paleotopography, 3) temporal reconstructions of deformation and magmatism in orogenic crust. My work aims to further our understanding of the timelines of deformation and magmatism, their direct links to orogen-wide and microscale heterogeneities in mountain belts, and to quantify the “fluid” bogeyman that is frequently evoked without direct evidence in mid-crustal processes.

Teaching Experience
Teaching at Colorado College
Geology 315: Rock Deformation and the Structure of Mountains
Intended Audience: Third and fourth-year Geology majors who have completed GY212, an introductory physics course, and introductory calculus.
Term(s) Taught: Spring 2024
Course Overview: This course is designed to build on fundamental geologic knowledge to build an understanding of the mechanics of rocks under stress. Students leave this course with a firm understanding of formation processes of faults, folds, fractures across spatial and temporal scales. In addition to understanding the theory, students learn several means of quantifying the strain response to stress, how varying tectonic settings appear in the structural record, and exit the course with the ability to apply quantitative and qualitative techniques to describe the deformational history of mountain belts from the hand sample to plate margin scale. The class focuses on didactic, mathematical, practical, and field-based practices to guide student development into well-rounded structural geologists.
Geology 212: Earth as a Physical System
Intended Audience: Second-year Geology majors who have completed GY140 or GY150.
Term(s) Taught: Spring 2024
Course Overview: Complementary to GY211 (Earth Materials), this class dives into the earth processes that cycle earth materials through physical processes. Namely, we focus on the formation of mountains through a surface and subsurface perspective that lays the groundwork for further investigation in GY315 Rock Deformation & the Structure of Mountains and GY320 Landscape Processes and Evolution. As such, this course is co-taught with Geomorphologist Sarah Schanz.
Critical to this class is the focus on how geologic knowledge is created. Students create their own geologic maps from start to finish, and use these as the basis to test complex hypotheses about the formation of the Colorado Front Range. Throughout the class, we also emphasize concept maps as a way to organize knowledge and to serve as visual components of the scientific process. Finally, knowledge creation depends on the questions that are asked; we end the course by practicing formulating new questions based on the concepts introduced throughout the course.
Geology 316: Field Analysis of Geological Structures
Intended Audience: Third and fourth-year Geology majors who have completed Geology 315 and associated prerequisites.
Term(s) Taught: Fall 2023
Course Overview: Building on fundamental concepts introduced in an upper-division structural geology course, this class is an immersive, field-based methods class designed to teach students advanced kinematic analysis of geologic structures, basic operation of near-surface geophysical instruments and data processing, cement field mapping techniques, and aid in developing a systematic approach to field-based research. The course involves daily field exercises and multiple overnight field trips. As a part of this course, students will develop a personalized field research plan based on their final project, a written report, and an oral presentation of field data.
Geology 203: Natural Hazards
Intended Audience: First or second-year Geology and Environmental Studies Majors who have taken Geology 140 or 150.
Term(s) Taught: Spring 2023, Fall 2023, Spring 2025 (planned)
Course Overview: Geologic processes have a profound impact on human society and experiences. This non-laboratory course aims to introduce students to a broad range of geological and environmental hazards (e.g., mass movements, earthquakes, tsunami, volcanos and associated features, mineral-associated health hazards, and wildfires), the fundamental processes driving them, how they produce a risk for local, regional, and global populations, and potential mitigation and response strategies. Teaching modalities involve a balance of lecture, student-led activities and discussions, field assessment of historic and active hazards, quantitative risk assessment, and hands-on exercises. The course typically involves a 4 day field trip to the Valles Caldera in north-central New Mexico.
Geology 101: Catastrophic Geology
Term(s) Taught: Spring 2023
Intended Audience: Non-geology majors and potential geology majors, variable backgrounds. No prerequisites.
Course Overview: Geologic processes directly or indirectly control major phenomena that cause damage or destruction to populations and/or leave lasting marks on Earth’s landscape or climate. This class aims to introduce a variety of significant processes and historical events demonstrating the destructive power of Earth systems through a variety of modalities including lectures, discussions, debates, in-class presentations, and field-based experiences.
Geology 150: Environmental Geology
Term(s) Taught: Fall 2022, Spring 2022
Intended Audience: Non-geology majors and potential geology majors, variable backgrounds. No prerequisites.
Course Overview: This course is designed to introduce students to core concepts of geology using Earth’s climate, as preserved in the geologic record and observable today, as a foundation. Key outcomes are the ability to interpret environmental clues in bedrock, an understanding of Earth’s natural climate variability, anthropogenic (human-caused) changes in Earth’s climate regimes, and linkages between the climate and deep Earth processes (e.g., plate tectonics). This information will be presented in a way that hopes to help first-year and non-major undergraduates find deeper connections between themselves and the environment they occupy.
Geology 140: Introduction to Earth Systems
Term(s) Taught: Fall 2022, Fall 2023, Fall 2024 (planned), Spring 2025 (planned)
Intended Audience: Non-geology majors and potential geology majors, variable backgrounds. No prerequisites.
Course Overview: This course is designed to introduce students to core concepts of geology using Earth’s climate, as preserved in the geologic record and observable today, as a foundation. Key outcomes are the ability to interpret the Earth as a holistic physical system that connects deep processes to surface and atmospheric phenomena. This course aims to provide a first-order understanding of major geologic phenomena, connections between the hydrosphere and lithosphere, and a basic ability to interpret key aspects of the geologic record based on field relationships and rock characteristics.
Geology 100—Hope and Hazards in the Green Energy Transition: Exploring the Geo-Societal Realities, Course Developer and Instructor
Term(s) Taught: Fall 2022
Intended Audience: Third and fourth-year non-geology majors, variable backgrounds. No Prerequisites.
Course Overview: Economically viable mineral resources are key to the capture, transport, and storage of solar, wind, and hydroelectric energy. As our society shifts from the limited resources provided by fossil fuels toward renewable resources, understanding the origin of rare earth elements and metal-bearing deposits, and the environmental and societal impact of their extraction is essential knowledge during the shift toward a more sustainable future. By focusing on the human and the environmental cost of mineral extraction, this course will provide a tour of the processes forming ore deposits, historical issues associated with mineral extraction, the impact of mining on communities in our backyard and across the globe, as well as modern practices to minimize the impact of resource extraction.
This course aims to provide a discussion-driven overview of the origin of ore minerals needed for green technology, the historical perspective of extraction of these resources, exploitation of indigenous populations to access them, the complexities of global extraction and migration of these often hard-to-find resources and future directions for ethical and less-impactful extraction practices. The central questions we return to throughout the class are:
How are major mineral resources formed, and how do formation processes control their global distribution?
What is the net environmental and societal impact of producing green technologies today?
How does this compare to traditional (e.g., fossil fuel) resource allocation and extraction?
How do we balance the need for renewable resources with the interests of all stakeholders (local populations, consumers, investors)?
Can we truly make “sustainable” resources sustainable and affordable without negative societal and environmental impacts?
