Robert Rohde

Robert Andrew Rohde is a 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."[1] He has recently attracted media attention because of his role in the Berkeley Earth project (also known as "BEST") as the lead scientist,[2] and was responsible for writing software that searched databases for global temperature records, compiled the records, and merged them into a global temperature record, a task that Muller compared to "Hercules's enormous task of cleaning the Augean stables."[3] With regard to Rohde's role in BEST, Muller also said that Rohde was responsible for extending the temperature record determined by the project back to 1753.[4]

Pre-BEST career

While a grad student, Rohde and Muller published a letter to Nature on the topic of mass extinctions throughout Earth's history. Rohde et al. found that such extinctions occur surprisingly regularly, about every 62 million years.[5][6] During this time, he also published two papers regarding microbial metabolism in ice crystals.[7][8] This research, which showed that microbes can survive in such conditions for up to 100,000 years, was reported on by New Scientist at the time of its publication.[9]
