Charles (Chuck) Hansen is an IEEE Fellow and a professor of Computer Science in the School of Computing and an associate director of the Scientific Computing and Imaging Institute at the University of Utah.

Chuck received a BS in Computer Science from Memphis State University in 1981 and a PhD in Computer Science from the University of Utah in 1987. Since 1997, he has been on the faculty in Computer Science at the University of Utah. From 2004 to 2012, he has been a visiting professor at the University Joseph Fourier, a SimTech Fellow at the University of Stuttgart, and a visiting scientist at INRIA-Rhone in the GRAVIR group. From 1989 to 1997, he was a technical staff member in the Advanced Computing Laboratory located at Los Alamos National Laboratory, where he formed and directed the visualization efforts in the ACL. He was a Bourse de Chateaubriand PostDoc Fellow at INRIA, Rocquencourt, France, in 1987 and 1988.

Chuck has published over 160 peer-reviewed journal and conference papers and has been a co-author on three papers recognized with Best Paper awards at the IEEE Visualization Conference (1998, 2001, 2002). He was co-author on the Best Paper at IEEE Pacific Visualization 2010. He was awarded the IEEE Technical Committee on Visualization Graphics "Technical Achievement Award" in 2005 in recognition of seminal work on tools for understanding large-scale scientific data sets. In 2017, the same committee awarded him the "Career Award" In recognition for his contributions to large-scale data visualization, including advances in parallel and volume rendering, novel interaction techniques, and techniques for exploiting hardware; for his leadership in the community as an educator, program chair, and editor; and for providing vision for the development and support of the field.

Chuck served on the VGTC board from 1995 to 2002. He was on the IEEE Visualization Conference steering committee from 2001 to 2004 and initiated term limits during that time. He has co-chaired IEEE Visualization 2000, was program co-chair for Visualization '99, and served as a papers co-chair for IEEE SciVis (then called IEEE Visualization) in 2007-2008. He co-Chaired IEEE LDAV in 2014.

Chuck is currently an associate editor-in-chief (AEIC) of IEEE Transactions on Visualization and Computer Graphics (TVCG) and was previously an AEIC for TVCG as well as on the editorial board of Elsevier Computers and Graphics Journals. His research has made contributions to the fields of scientific visualization, computer graphics, parallel computation, and computer vision.
