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 Earth & Planetary Sciences. 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 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 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. He especially enjoys sharing his knowledge of the world’s geology, climate, and natural resources with undergraduate students in his introductory-level courses at Yale.
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 was BK’62 and his sister was BK’89. Aside from cheering on, often fruitlessly, his favorite professional sports teams (the Green Bay Packers and Milwaukee Bucks), Head Evans’s main extracurricular passion is music, regularly playing contrabass in the Berkeley College Orchestra and occasionally slapping a bass guitar or reciting old-school hip-hop lyrics.
The Associate Head of Berkeley College, Lely Dai Evans, is a language educator and educational consultant. Raised in Taiwan, Lely received her B.A. at Occidental College and a master’s of music in performance practice from The University of Western Australia. Most recently, Lely has co-founded New Haven Chinese Cultural Cooperative (NHCCC), in which she performs the guzheng (a 21-string acient zither). Lely also loves cooking and brings many aspects of food preparation, as well as music, into her teaching repertoire.
Sarah Layedra, Assistant Director of Operations, Berkeley College
Sarah Layedra joined Berkeley College in June 2017 and is the Assistant Director of Operations, Berkeley College. With direction from Head of College David Evans, Sarah is responsible for managing the financial and administrative operations of Berkeley. This includes overseeing the college’s finances, events, and facilities. She is also the coordinator of the Paul Mellon Fellowship. In addition, Sarah oversees special projects, and serves as liaison between the college and the Yale College Business Office. This deceptive description fails to explain how truly vital Sarah is in maintaining the collegiate environment. She manages every facet of college life including the oversight of College funds, fellowships and events. Because of Sarah’s involvement in many aspects of Berkeley College life, she will often be a student’s first recourse for questions about fellowships and college life. At most every event, you will find her working behind the scenes with Adriana Rivera and the College Aides to ensure its success.
Sarah’s favorite free time activity is spending time with her husband José and sons, Andrés and Mateo.
Sarah is in F20 and can be reached by e-mail at sarah.layedra@yale.edu or at (203) 436-2899 on weekdays.

Adriana holds a B.S. in Business Administration with a concentration in Industrial-Organizational Psychology from Southern New Hampshire University. She takes pride in contributing her skills and experience to support Yale’s students and community.
A lifelong Connecticut resident, Adriana enjoys the state’s four seasons—especially spring. She describes herself as kind and supportive, and in her free time, she enjoys traveling, staying active, and cooking. As a former restaurant owner, she still loves preparing Puerto Rican fusion cuisine for her family and friends. One of her long-term goals is to plan and participate in a mission trip abroad.
Jolanta Skonieczna, Residential College Service Assistant II, Berkeley College
Jolanta Skonieczna joined Berkeley College in February 1996 as the Swensen House Service Assistant II. She is always ready to serve students and faculty. Jolanta came to the USA from Poland.
