A member of the Hamilton faculty since 1985, Domack earned his Ph.D. in geology at Rice University. Specializing in the sediments, paleoenvironments, and glacial geology of the Southern Hemisphere, Domack has been the chief scientist aboard many research vessels to Antarctica. Over the last 15 years Domack has led more than 100 undergraduates to Antarctica as part of his NSF sponsored research program. He has published many articles for journals such as Nature, Antarctic Science, Marine Geology, and Geological Society of America Bulletin, and has also edited the book, The Earth's Glacial Record. Domack has been awarded many grants for Antarctic study by the National Science Foundation, who also presented him with the Antarctic Service Award in 1981. In January 2007 he was appointed to the newly endowed J. W. Johnson Family Professorship of Environmental Studies, and reappointed in 2012.
