Lesley died Aug. 30, 2017, in Davis, Calif., almost four years after her diagnosis with neuroendocrine (atypical carcinoid) lung cancer. She was a brilliant environmental law scholar as well as a devoted wife, mother, sister, daughter, and dear friend to many.

Lesley came to Princeton from Cincinnati and majored in civil engineering with a certificate in the Woodrow Wilson School. She was an Outdoor Action leader and loved walking in the woods of the Institute for Advanced Study. After college Lesley served in the Peace Corps in Costa Rica and earned her master’s and doctoral degrees from the University of California, Berkeley, and her law degree from Stanford.

Lesley’s professional work at the University of California, Davis, centered on the role of law and regulation in addressing climate change and other environmental problems. She enjoyed hiking, camping, cycling, and travel with her family.

She is survived by her husband, Andrew; her children, Nathan and Erin; her parents, Deanne and Barry Barnhorn of Cincinnati; and a sister and brother.

Lesley took great comfort in the Dharma and fiercely pursued resources for the care and support of children — hers and others. She asked that any gifts in her memory go to the Saranaloka Foundation, the Insight Retreat Center, or Camp Kesem. Lesley made the world a better place. We are grateful for her life and we miss her deeply.
