Ian is Research Professor at UTIG and a Professor of Geological Sciences at The University of Texas at Austin. He is a John J. and Katherine J. Jackson Research Fellow for 2009-2010. Ian has dedicated most of his career to understanding global tectonic processes and to mapping out the geography of ancient times on a dynamic Earth. His 35 years of field experience have been devoted to work in the British Caledonides, the Canadian Shield, the Andes, and Antarctica. NSF-sponsored fieldwork in Antarctica between 1995 and 1998 led Ian to propose that ancestral North America, known to geologists as Laurentia, was connected to South America, Africa, and Antarctica one billion years ago by a large promontory, which he named the "Texas Plateau" (see Powerpoint animations "Texas Through Time" and "From Texas To Antarctica" and "Making of Texas" poster). The results of this work were published in the January 1995 issue of Scientific American. Working with colleagues from the U.K. and Australia, Ian has turned his attention to unraveling the complicated tectonic history of Scotland, his homeland. Recently, Ian has been studying the possible link between the an Iapetus-Pacific oceanic connection and the Cambrian transgression and radiation.

Ian was president of the International Division of Geological Society of America from 1996 to 1997, has served as delegate to the Scientific Committee on Antarctic Research of International Union of Geological Sciences since 1987, and has served as the International Secretary of the American Geophysical Union since 1996.
