Mark Bush is a professor of Biology at the Florida Institute of Technology. He earned his BSc , PhD and PGCE (teaching diploma) at the University of Hull, UK. He was a post-doc at The Ohio State University and Smithsonian Tropical Research Institute. In 1992, he was appointed to the faculty of Duke University before meeting his wife who wanted to move to a warmer climate. He has been faculty at Florida Tech since 1996. His research sits at the nexus of biogeography, ecology, paleoclimatology and archaeology in the Andes and Amazonia. He uses the microfossils and chemistry of lake sediment cores to recreate past environments and determine how systems have changed through time. Some of his work is on relatively long time-scales, looking at the last 1,000,000 years, whereas the same techniques are also applied to looking at changes of the last few decades.
