Janine is an archaeologist studying past faunal and ecological communities and specializing in zooarchaeology. She is interested in investigating palaeoenvironments, biogeographic patterns, island evolution of terrestrial vertebrates, and systems of indigenous ecological knowledge. She is currently working on fossil vertebrate assemblages from archaeological sites in Luzon and Palawan Islands. Her work includes the description of the first fossil records of the tiger on Palawan Island and the publication of three previously unknown, extinct species of cloud rats from Luzon.
