Since becoming the Collections Manager in 2019, he has contributed to expeditions and surveys along the Baja California peninsula, deserts of southern California, and throughout much of San Diego County.

Volunteers

The normal day-to-day accomplishments of the department would not be feasible without our core group of volunteers. Volunteer projects include making fieldguide webpages, digital mapping, fieldwork, and collections renovation.

The department is currently not accepting new volunteers. 

Be sure to check out other volunteer opportunities on the  Current Needs page. We offer a wide range of activites for individuals interested in natural history.
