Head of College’s Office

The Head of College is the head and ranking officer of Berkeley College, responsible for the college’s intellectual, social, athletic, and artistic life. The college is administered through the Head of College’s Office, which is staffed by an operations manager, senior administrative assistant, and student aides. The Head of College works closely with the Dean, Resident Fellows, the Dining Hall Manager, and other staff to build the best possible community for our students.

Head of College David A.D. Evans    


David A.D. Evans is a member of the faculty of the Department of Geology & Geophysics. Professor Evans focuses his research on plate tectonics, the past motions of continents across Earth’s surface. He is director of the Yale Paleomagnetism Laboratory, which traces this movement by measuring fossil magnetism preserved in ancient rocks from around the world. His undergraduate classes at Yale span from introductory geology to global tectonics, natural resources, and changes in Earth’s climate. In these courses and for his research, he has taken students on numerous geological field trips across the New England Appalachians, as well as to more far-flung destinations including Australia, Barbados, Canada, Italy, Namibia, New Zealand, Norway, and South Africa.

His work has elucidated the configurations of vanished supercontinents named Pangea, Rodinia, and Nuna (each separated by about 600 million years); characterized the geometry of Earth’s ancient magnetic field; and provided evidence for globally engulfing “Snowball Earth” ice ages that occurred deep in earth’s history, around the time when animals were first evolving. He has co-led two UNESCO-based international geological projects to examine ancient supercontinents and their relation to the broader Earth system.

Professor Evans grew up in the suburbs of Milwaukee, Wisconsin, and graduated from Yale College (where he was a resident of Berkeley) in 1992. His is a family of Berkeleyites: his father is BK’62 and his sister is BK’89. He earned his Ph.D. at the California Institute of Technology and conducted postdoctoral research at the University of Western Australia before joining the Yale faculty in 2002. That same year, he received a competitive research fellowship for early-career scientists from the David & Lucile Packard Foundation; in 2015, he was elected a fellow of the Geological Society of America, receiving the society’s George P. Woollard Award “for outstanding contributions to geology through the application of the principles and techniques of geophysics.”

Also joining the Berkeley community are Professor Evans’s wife, Lely Dai Evans, an accomplished violinist and teacher of Mandarin Chinese at the Foote School and the New Haven Chinese Language School; their daughter Corinne, age 13, and son Jamie, age 12; and the family’s dog, Brie. The Evanses share a passion for music: David and Lely met as students in the joint orchestra of Caltech and Occidental College, and she received a master of music degree from The University of Western Australia (in early violin performance practice), while he is a bassist and a member of the Berkeley College Orchestra. Lely also loves cooking and brings many aspects of food preparation, as well as music, into her classes.

The family members share a love of active international travel, playing games, and attending the New Haven Chinese Language School, which meets in WLH on Sunday mornings, just steps away from their new home! Corinne is an avid reader who enjoys creative writing, MathCounts, and progressive rock music; Jamie likes pencil drawing, playing piano, and “all sports except for baseball and softball,” and recently walked with his father across Connecticut to raise funds for the UN Refugee Agency. Both children practice capoeira, a Brazilian martial art that combines dance, acrobatics, and music. Brie, a cavachon (half cavalier spaniel, half bichon frise), already has an international fan base, which she looks forward to extending to Yale’s central campus.

College Aides


College Aides are sophomores, juniors, and seniors who have been chosen by the Head of College to assist Sarah and Naomi in the running of the college. They help organize the many events sponsored by the Head of College’s office, from the Freshman Picnic at the beginning of the year to the Berkeley Commencement in May. Each is responsible for specific areas of the College, including the Berkeley Bagel Bar, and the Library. They can often be found in the Head of College’s Office helping make life slightly less stressful for Berkeleyites.
