Today's guest, Anusha Shankar studies hummingbirds as a Rose Postdoctoral Fellow at the Cornell Lab of Ornithology. She has lived and worked on four continents and loves being an Indian woman in science. She is fascinated by hummingbirds' ability to use a hibernation-like state called torpor to save energy at night. She is investigating how they can get cold (10°C / 50°F) and rewarm safely every night, without damaging organs like their hearts and brains. During her PhD, Anusha captured hummingbird nightlife with infrared video, and before that tracked king cobras and studied giant birds—hornbills—in India. Anusha is also a National Geographic Explorer and Young Leader and loves mentoring students, dancing salsa, bachata, and swing, and reading fiction.
