scarabaeoid beetles, especially scarabs of southern California,
USA, and Baja California, Mexico. His current research projects
a study of the biology and taxonomy of San Diego County, California
scarabaeoid beetles, a study of the systematics and natural
history of Scarabaeoid beetles in Baja California, Mexico, natural
history and description of Trox gemmulatus Horn larvae,
a survey of the Scarabaeoid beetles inhabiting Juniper Dunes
