Ethan Freedman studied biology and environmental studies at Tufts University and the School for Field Studies. This took him to field work in the grasslands of Tanzania, rainforests of Costa Rica, swamps of Massachusetts and islands of California, mainly studying birds. But it also reminded him how much he likes telling stories, so that’s what he does now. Other than that, he likes cross-country skiing, live music and cooking with friends.
