Matthew D. Eisaman ’00

Matt died Feb. 28, 2025, of cancer in Port Jefferson, N.Y. He was 46.

Matt’s academic and career accomplishments after his A.B. in physics included a Ph.D. in physics at Harvard, stints at Brookhaven National Laboratory, Stony Brook, Google X, and founding the carbon capture startup Ebb Carbon.

At the time of his passing, Matt held an endowed chair in the Department of Earth and Planetary Sciences at Yale University. At our 25th reunion, Matt’s friends, his widow, Heather Lynch ’00, and daughter Avery gathered at Jadwin Hall, where Matt spent many hard-working days and nights. They celebrated how Matt’s brilliance was matched by his goodness. Friends spoke of his work ethic, focus on the welfare of others (including his students), love of the outdoors, belief in his work to mitigate climate change, lifelong partnership with Heather, and the joy he brought to being a father. A reading from Matt’s hand-marked and well-read copy of Tao Te Ching shared a lesson from his life: “Therefore, the contentment of knowing contentment is constant contentment.”

The class, so proud to claim Matt, stands with all his survivors at their time of loss and in the years ahead.
