In addition to reasonably intensive field work on Yagua, Panare, and Maasai, I have worked more cursorily on the following languages and language families, sometimes in conjunction with other investigators:

Quechua, Arabela (Zaparoan), Huitotoan, Tucanoan, Arawakan, Tupí-Guaraní,  various western Amazonian languages, Blaan and other Philippine (Austronesian) languages,  Bantu, Biblical Hebrew, Indonesian, Sabaot
