Dr Lye Tuck-Po is an environmental and visual anthropologist at Universiti Sains Malaysia and long-term (28 years) student of the Batek (Orang Asli) of Pahang. Currently she is working with them on ethnoprimatology and acoustic knowledge, primarily of gibbons. Her most recent publication was "Tracking with Batek Hunter-Gatherers of Malaysia" (2021). She is the author of the monograph Changing pathways: Forest degradation and the Batek of Pahang, Malaysia (2004). Her interests in memory stem from the conviction that alternative (vernacular) ways of knowing are often discounted or denied. Her photography work can be found at: https://www.instagram.com/tplye/
