Michael Wall, Ph.D., Curator of Entomology / Vice President of Science and Conservation

Michael Wall, Ph.D., conducts research on insect evolution and spearheads the biodiversity research and conservation efforts at The Nat. A key part of the leadership team, he joined the Museum as curator of entomology in January 2006 and was subsequently named director of the Biodiversity Research Center of the Californias (BRCC).

Dr. Wall is passionate about collections-based research and regional exploration. In 2008, Dr. Wall coordinated the Museum’s first-ever BioBlitz in which 1,035 species were discovered in Balboa Park over a 24-hour period. He is currently working to develop online resources that will increase public accessibility to the Museum’s rich biological collections.

Dr. Wall’s interest in natural history began with plants. While working on both a bachelor of science (B.S.) and master of science (M.S.) in botany at Auburn University, he became interested in the ecological relationships between plants and insects. After completing his doctorate of philosophy (Ph.D.) in entomology at University of Connecticut in 2004, Dr. Wall received a postdoctoral fellowship to join a global biodiversity inventory (organized by the American Museum of Natural History and the Australian Museum). He is an award-winning teacher and Fulbright Fellow. He can be reached at 619.255.0266 or

Pamela has more than 15 years of experience working in collections management and museum registration and has a keen interest in the best practices and management of pinned, slide, and fluid-preserved invertebrate collections. She earned her M.S. in entomology from McGill University studying the systematics of central American weevils (Coleoptera: Curculionidae). Her duties include general curation, coordination and management of museum-wide collection transactions and compliance, collection digitization and database management, supervision of department science volunteers and project staff, and whenever possible joins in to conduct fieldwork for the museum.

The Entomology Department has a large and active volunteer staff who are responsible for specimen preparation and sorting, as well as participating in the research activities of the department. There is work available at a range of levels, to suit those with little background in entomology as well as those with extensive training and experience.

If you are interested in volunteering in this or other opportunities, please complete an online application on the volunteer pages. The Director of Volunteers will contact you to schedule an interview or invite you to an orientation.
