In the summer of 2009, I joined a research trip to Papua New Guinea. Our destination was the Yupno valley, a high nook in the Finisterre Range, one of countless similar nooks in the country's remote, rumpled interior. The trip was jointly led by Jürg Wassmann, an anthropologist at the University of Heidelberg, and Rafael Núñez, my advisor in the Department of Cognitive Science at UCSD, where I was getting my PhD. I bought my first digital SLR for the trip. Here are some of the portraits I took with it.
