About me

I am currently based in the Department of Global Health Systems and Development (formerly International Health & Development) at Tulane University in New Orleans. I also have appointments in the Payson Center for International Development and the Roger Thayer Stone Center for Latin American Studies at Tulane. I teach a range of courses on the intersection of population, environment, technology, and development (see Teaching pages).

My research has focused on the livelihoods of the poor, the implications of the African HIV/AIDS epidemic, and the social shaping of technologies, such as mobile phones and kitchen gardens. Find project manuscripts, articles, presentations and other materials under Research. I welcome collaboration in fieldwork, analyses and writing projects and sometimes have funding.

My formal education: undergraduate training (BS, 1983, Stanford, Mechanical Engineering and Values, Technology & Society) and a doctorate from UNC-Chapel Hill in City & Regional Planning (1998). Informal education: living and working around the world. Highlights of my formal employment record: Yosemite Airlines in Columbia, California (1975-79), the Indonesian Environmental Forum in Jakarta (1983-1986), the Canadian High Commision in Kenya (1988-1991), starting up the Population Environment Research Network (2000-2002). Informal employment: raising my son. I live and work in New Orleans and Nairobi.
