Joseph L. Kirschvink (born 1953) is an American geologist and geophysicist. He is the Nico and Marilyn Van Wingen Professor of Geobiology at Caltech,[1] known for contributions to paleomagnetism[2] and biomagnetism[3] (discovery of the first magnetofossils) and the Snowball Earth hypothesis.[4] He is also Principal Investigator (PI) of Earth–Life Science Institute.

In 2021, Caltech settled with the Department of the Interior to pay $25,465 for damages to petroglyph sites in Volcanic Tablelands after they were damaged by Dr. Kirschvink on Earth Day 2017.[5] [6]
