Tullis Onstott (January 12, 1955 – October 19, 2021) was a professor of geosciences at Princeton University who has done research into endolithic life deep under the Earth's surface. In 2011 he co-discovered Halicephalobus mephisto, a nematode worm living 0.9–3.6 km (0.56–2.24 mi) under the ground, [2] the deepest multicellular organism known to science. He won a LExEN Award for his work "A Window Into the Extreme Environment of Deep Subsurface Microbial Communities: Witwatersrand Deep Microbiology Project". [3] In 2007, Onstott was listed among Time Magazine's 100 most influential people in the world. [4]
Onstott attended the California Institute of Technology and was awarded a B.S. in Geophysics in 1976. He later moved to Princeton University to earn a M.A. in 1978 and later a Ph.D. in 1980, both in Geology, under the direction of Robert B. Hargraves. [5] After receiving his doctoral degree, Onstott, spent the next three years as a postdoctoral fellow in Derek York's laboratory at the University of Toronto performing research involving 40Ar/39Ar geochronology, before returning to Princeton as a professor. [6] Onstott died October 19, 2021, after a long illness. [7]
Research projects include: [8]
The first two research projects were done in collaboration with stable isotope biogeochemist and colleague Lisa Pratt of Indiana University. [10]
