Amy Mainzer

Principal Investigator, NEOWISE and NEO Surveyor, Professor

Ph.D., 2003, University of California, Los Angeles

Years with LPL: 2019 to present

Asteroid Surveys, Small Bodies, Remote Sensing, Instrumentation, Education and Public Outreach

Prof. Mainzer's research focuses on understanding the populations of small bodies in our solar system, including characterizing their basic physical and dynamical properties and the potential impact hazards they may pose to Earth. Prof. Mainzer uses orbital and ground-based facilities for this work. She serves as the Principal Investigator for NASA's Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE) mission, an Earth-orbiting satellite that uses infrared sensors to characterize asteroids and comets. She is also leading NASA's Near-Earth Object (NEO) Surveyor mission, currently in development, which will carry out a comprehensive survey for the most potentially hazardous NEOs.

Prof. Mainzer has also embarked on new research to study the distribution of invasive weeds driving wildfires and causing loss of biodiversity using hyperspectral imaging, LiDAR, and field work. The aim of the project is to assist agencies charged with management to mitigate emerging invasions and optimize restoration plans.

Prof. Mainzer is the Past Chair of the American Astronomical Society's Division for Planetary Sciences (DPS), the world's largest professional society of planetary scientists. She is also serving as the Chair of NASA's Planetary Advisory Committee (PAC). She is the science consultant, co-executive producer, and on-camera host of the PBS Kids television show Ready Jet Go!, which aims to teach basic physics, Earth science, and astronomy to children ages 3-8.
