Question: Who is the American physicist who studied under the founder of "Berkeley Earth"?

Context paragraphs:
Walter M. Elsasser: Walter Maurice Elsasser (March 20, 1904 – October 14, 1991) was a German-born American physicist considered a "father" of the presently accepted dynamo theory as an explanation of the Earth's magnetism.  He proposed that this magnetic field resulted from electric currents induced in the fluid outer core of the Earth.  He revealed the history of the Earth's magnetic field through pioneering the study of the magnetic orientation of minerals in rocks.

Garniss Curtis: Garniss H. Curtis, (born May 27, 1919 – died December 19, 2012) was a professor emeritus of geology at the University of California, Berkeley, geochronologist, volcanologist, geophysicist, and founder of the Berkeley Geochronology Center.  In 1960, Curtis and fellow UC Berkeley geophysicist Jack Evernden used potassium-argon dating methods developed by UC Berkeley physicist John Reynolds on minerals found in tephra deposits collected by Evernden to date Mary Leakey's 1959 Olduvai Gorge Bed I hominin "Zinjanthropus" ("Paranthropus boisei") to 1.89 to 1.57 Mya.  The great age of the fossil hominid and associated stone tools in the bed pushed back the then accepted age of the Pleistocene another million years, causing a stir in the geology community.  The dating of these fossil finds is considered a starting point for the collaboration of paleoanthropology and geochronology.

Roger Falcone: Roger W. Falcone is an American physicist, currently at University of California, Berkeley and is an Elected Fellow at American Academy of Arts and Sciences, The Optical Society, American Physical Society.

Benson Mates: Benson Mates (May 19, 1919, Portland, Oregon – May 14, 2009, Berkeley, California) was an American philosopher, noted for his work in logic, the history of philosophy, and skepticism.  Mates studied philosophy and mathematics at the University of Oregon, Cornell University, and the University of California at Berkeley.  Some of his teachers included J. Barkley Rosser, Harold Cherniss, and Alfred Tarski.  From 1948 until his retirement in 1989, he was a professor of philosophy at Berkeley.  He remained Professor Emeritus of philosophy at University of California at Berkeley until his death.

Forbush decrease: A Forbush decrease is a rapid decrease in the observed galactic cosmic ray intensity following a coronal mass ejection (CME).  It occurs due to the magnetic field of the plasma solar wind sweeping some of the galactic cosmic rays away from Earth.  The term "Forbush decrease" was named after the American physicist Scott E. Forbush, who studied cosmic rays in the 1930s and 1940s.

Andrew Sessler: Andrew Marienhoff Sessler (December 11, 1928 – April 17, 2014) was an American physicist, academic (University of California, Berkeley), former director of the Lawrence Berkeley National Laboratory (1973–1980), humanitarian and former president (1998) of the American Physical Society.

Mary K. Gaillard: Mary Katharine Gaillard (born April 1, 1939) is an American theoretical physicist with a focus on particle physics.  She is a professor of the Graduate School at the University of California, Berkeley and Visiting Scientist at the Lawrence Berkeley National Laboratory.  She was Berkeley's first tenured female physicist.

Berkeley Earth: Berkeley Earth is a Berkeley, California based independent 501(c)(3) non-profit focused on land temperature data analysis for climate science.  Berkeley Earth was founded in early 2010 (originally called the Berkeley Earth Surface Temperature project) with the goal of addressing the major concerns from outside the scientific community regarding global warming and the instrumental temperature record.  The project's stated aim was a "transparent approach, based on data analysis."  In February 2013, Berkeley Earth became an independent non-profit.  In August 2013, Berkeley Earth was granted 501(c)(3) tax-exempt status by the US government.  The primary product is air temperatures over land, but they also produce a global dataset resulting from a merge of their land data with HadSST.

Robert Rohde: Robert Andrew Rohde is an American physicist and former graduate student at the University of California, Berkeley, where he studied under Richard A. Muller.  He received his PhD in 2010 with a thesis entitled "The Development and Use of the Berkeley Fluorescence Spectrometer to Characterize Microbial Content and Detect Volcanic Ash in Glacial Ice."  He is also the founder of the website Global Warming Art and a Wikipedia editor under the username "Dragons Flight".

Richard A. Muller: Richard A. Muller (born January 6, 1944) is an American physicist and professor of physics at the University of California, Berkeley.  He is also a faculty senior scientist at the Lawrence Berkeley National Laboratory.  Most recently, in early 2010, Muller and his daughter Elizabeth founded the group "Berkeley Earth", an independent 501(c)(3) non-profit aimed at addressing some of the major concerns of the climate change skeptics, in particular the global surface temperature record.
