Nationally Known Earth Scientist to Deliver 2011 Sigma Xi Lecture

Dr. Marc Imhoff of the National Aeronautics and Space Administration (NASA) will visit Kirksville Jan. 20 for two free public lectures.

The first lecture, entitled “Human Appropriation of Net Primary Production—Can the Earth Keep Up?” will be presented at 12 p.m. in Mehegan Classroom, located on the ground floor of the Gutensohn Clinic at A.T. Still University. The second lecture, entitled “Planetary Secrets: The Secret Lives of Storms, Deserts and Fires,” will be presented at 8 p.m. in the Student Union Building Alumni Room.

Imhoff works in the Earth Sciences Division at NASA’s Goddard Space Flight Center as the project scientist for Terra, NASA’s Flagship Earth Observing System Mission. As Terra project scientist, Imhoff coordinates an international research team using Terra and other instruments to study Earth’s changing atmosphere, oceans and land surface. He has personally conducted research on a wide range of topics including the impact of urbanization on biodiversity and food security, urban heat islands and climate and carbon accounting using remote sensing for the Kyoto Protocol. He was a primary developer of the satellite imagery showing Earth’s cities at night and pioneered the use of radar sensors for terrain and vegetation mapping.

Imhoff holds a bachelor’s degree in physical geography and a master’s degree in agronomy from The Pennsylvania State University, as well as a Ph.D. in biological sciences from Stanford University. His visit is sponsored by Sigma Xi, the scientific research society and the Kirksville chapter of Sigma Xi. For more information, contact Michael Goggin at

Sigma Xi, the scientific research society, is a membership honor society of roughly 91,000 scientists and engineers. The goals of the society are to honor scientific accomplishments, to encourage and enhance worldwide appreciation and support for scientific research and to foster a creative and dynamic interaction among sciences, technology and society. Members participate at the local level through more than 500 chapters and clubs. The Kirksville chapter, chartered as a club in 1989 and as a chapter in 1995, is composed of approximately 60 members representing scientists in the Northeast Missouri region, including the faculty and students of both Truman State University and the Kirksville College of Osteopathic Medicine. Each spring the Kirksville chapter hosts a Sigma Xi National Lecturer, such as Imhoff, to give a public lecture.
