Asher is eccentric and inquisitive. He loves an audience, likes keeping busy, and howls to be let through doors. He is a six-year-old working Cocker Spaniel, who, with five other furry colleagues, has now been trained to sniff body odor samples from humans to detect COVID-19 infections.

Angela Rasmussen
Dr. Angela Rasmussen uses systems biology techniques to interrogate the host response to viral infection. She has studied a huge range of viral pathogens, from the “common cold” (rhinovirus) to Ebola virus to highly pathogenic avian influenza virus to SARS-CoV-2/COVID-19. By combining current classical approaches to modeling infection and pathogenesis with sequencing technology and machine learning, Dr. Rasmussen and her colleagues and collaborators have identified new host mechanisms by which viruses cause disease.
