Six years as a PhD student in the City University of New York's graduate school of environmental psychology gave Bih a different perspective on society. Bih's classmates at CUNY were drawn from all segments of society, and included people from poor backgrounds, minorities, women, and homosexuals.
而六年的紐約市立大學環境心理學博士班生活，更讓畢恆達學習不同的社會觀察角度，學校同學由各種社會邊緣人構成，有窮人家孩子、少數族裔、同性戀者、女性等。
