Lecturer: Santa Clara University, BIO 023: Investigations in Evolution and Ecology. Instructor of record for an introductory course on the experimental and statistical approaches used in modern ecological and evolutionary studies, with an emphasis on experimental design, data analysis, interpretation and presentation.  Course includes lecture and laboratory sections, involving in-lab and field activities.  Spring 2010-2014.

Lecturer: Santa Clara University, BIO 022: Introduction to Evolution and Ecology. Instructor of record for an introductory course on the key concepts in evolution and ecology, including population genetics, natural selection and adaptation, phylogenetics and biodiversity, demography, and interactions among organisms and their environments.  Winter 2014.

Lecturer: Santa Clara University, BIO 156: General Ecology. Instructor of record for an upper-division course examining the factors that limit the distribution, abundance, and diversity of organisms, including the physical environment and interactions with other species.  Topics: population dynamics, interspecific relationships, community structure, and ecosystem processes. Fall 2009, Winter 2012-2013.

Lecturer: Santa Clara University, BIO 144: Natural History of Baja California. Instructor of record for an upper-division course on the natural history and ecology of the Baja Peninsula.  This course is taught in conjunction with a course on Natural History Writing led by Dr. John Farnsworth.  Lectures are presented weekly through the winter quarter, culminating in a 10-day trip exploring the Baja Peninsula and Isla Espiritu Santo in the Sea of Cortez through hiking and kayaking.  Winter 2011-2012.
