Heather was such a lovely, positive, warm and thoughtful friend. I will never forget meeting and starting to know her on our 2008 trip to the UNFCCC climate conference in Poland. She was instantly so welcoming, so open. And we had so much fun there, arriving together on the plane and taking funny photos....and she was an inspiration to me with her UN work. I then followed in her footsteps, living in her apartment in New Haven after she had left Yale. She was a generous soul, always reaching out and helping her friends. Heather, you are missed and loved.
