Zack became interested in Buddhist meditation as a teenager. He attended Stanford University, where he completed a BA in Religious Studies focusing on Buddhism, with a minor in creative writing. He then spent eleven years based in the Tibetan community of Boudhanath, Nepal. There, he first studied and earned an MA at Rangjung Yeshe Institute before eventually working at RYI for four years as a teacher and interpreter.
Under the umbrella of Dharmachakra Translation Committee, he has published a number of translations, including works on development-stage practice by Shechen Gyaltsab (in Deity, Mantra, and Wisdom and A Practice of Padmasambhava, both published by Snow Lion) and several sūtras for 84000. In 2014, he began his PhD studies at the University of California at Berkeley, where he is currently completing a dissertation on the topic of secrecy in early Tibetan Buddhism.
Zack lives in New York State and spends his free time baking bread and watching birds.
