My goal as an educator is to create an inclusive, dynamic, and equitable classroom that provides base knowledge, develops quantitative and communication skills, and inspires students to follow their inquisitive nature through open inquiry and critical thinking. I strive to achieve these goals everyday by utilizing evidence-based practices, a diversity of pedagogical tools, and encouraging students to participate in their learning through inquiry-based activities and conducting primary research.
Research Interests:
My research focuses on illuminating the processes and interactions that shape and record patterns of biodiversity. My team and I investigate modern ecology paleoecology, and paleoenvironmental questions using biogeochemical data, geospatial data, and the fossil record. Recent work used stable isotopes to investigate food resource partition by small mammals in response to environmental change today and over the last four million years in the Great Plains.
