Professor Hansen’s teaching experience at UW is extremely broad, having taught some 20 different courses spanning 4 departments and two colleges.  His primary area of expertise is the field of engineering mechanics with a particular emphasis on numerical and theoretical aspects of solid mechanics.

His research interests generally have focused on a host of fascinating challenges associated with modeling multiphase mixtures.  Specific studies have covered such diverse topics as snow mechanics related to avalanche initiation to failure of high performance composite materials.  The latter work led directly to the formation of a university spin-off company known as Firehole Composites—named after the famous river located in Yellowstone Park.

Professor Hansen has served UW in a variety of administrative roles including department head, associate dean, and Associate Director for Academics for the School of Energy Resources.  He also served a unique administrative appointment in the Office of the President as a Presidential Faculty Fellow from 2003-2005.  Responsibilities of this position spanned the full range of activities of the President’s Office including involvement with institutional planning and policy making, legislative and public relations, and facilities development and private fund raising.

A major effort of Dr. Hansen during his Presidential Fellowship was devoted to studying ways to increase the college participation rate of Wyoming high school graduates.  As a result of this experience, he was appointed by the Governor to serve on a state-wide legislative committee from 2005-2007, with the charge of developing legislation for the Hathaway Scholarship Program to be funded through a $400 million endowment.  The Wyoming Legislature passed the Hathaway legislation in the spring of 2006, providing a landmark achievement for access for Wyoming students to higher education.

Andy has also been active in the Laramie community.  From 1999-2001, he completed a two-year tenure as President and Vice President of Laramie Youth Baseball.  He also coached in Laramie Youth Baseball for a decade.  He thoroughly enjoys a variety of outdoor activities including skiing, hiking, and rock climbing.
