CISL Director's Office

The Director's Office of the Computational and Information Systems Laboratory (CISL) at the National Center for Atmospheric Research (NCAR) works to ensure that geoscientists have a balanced mix of computational resources to study the complex processes that make up the Earth system, from the ocean floor and atmosphere to the Sun's core.

These computational resources include high-performance computers, high-speed networks, a world-class data archiving and storage facility, research data sets, state-of-the-art knowledge environments and visualization technologies, advanced mathematical tools, and a staff of professionals dedicated to advancing Earth systems science across broad fronts.

CISL is composed of two divisions and one NCAR-wide institute:

  • Operations and Services Division (OSD) includes most of the computing-center functions familiar to external users.
  • Technology Development Division (TDD) incorporates scientific visualization, computer science, and the Earth System Modeling Infrastructure.
  • Institute for Mathematics Applied to the Geosciences (IMAGe) facilitates connections between the mathematical and geophysical communities across all NCAR labs and divisions as well as the external university community. IMAGe also conducts research and supports tools and algorithms that use mathematics to strengthen geosciences research.

Anke was named CISL Director in June 2017 after serving as Interim Director since November 2016. She joined CISL in July 2009 as director of its Operations and Services Division. Prior to coming to NCAR she worked for 22 years at the San Diego Supercomputer Center at the University of California, San Diego in a variety of leadership positions. She has over 29 years experience in supporting, operating, deploying and managing world-class supercomputing resources. Prior to her experience in supercomputing, Anke worked as a rocket scientist at the Aerospace Corporation in El Segundo, California. She holds a M.S. in Mechanical Engineering from U.C. Berkeley

Institute for Mathematics Applied to Geosciences (IMAGE)
Doug Nychka, IMAGE Director
303-497-1711 or
Doug has served as the Director of the Institute for Mathematics Applied to Geosciences (IMAGe) and as a Senior Scientist in the Geophysical Statistics Project (GSP) since November of 2014. His main task is to enrich the scientific and educational activity at NCAR through mathematical methods and models. Also, he uses the large scientific projects at NCAR to engage the mathematical science communities in new applications and to motivate new mathematicsand statistics. Before directing IMAGe he served as the GSP project leader between August,1997 and June, 2006.

Operations & Services Division (OSD)
Aaron Andersen, OSD Director
303-497-1837 or
Aaron Andersen is the Deputy Director of Operations and Services housed in the Computing and Information Systems Lab (CISL) of the National Center for Atmospheric Research. Aaron has over 20 years of experience and expertise in both facilities and information technology. Aaron oversees the computing facilities at NCAR and was the project engineer for the NCAR-Wyoming Supercomputing Center (NWSC) design and construction effort. Aaron has a Bachelor of Science in Mechanical Engineering and a Masters of Computer Science from the University of Colorado Boulder.

Technology Development Division (TDD)
Rich Loft, Director of TDD
303-497-1262 or
Rich has been involved with massively parallel computing since joining Thinking Machines Corporation as an Application Engineer in 1989. Throughout his career he has contributed to the understanding and effective use of parallelism as applied to grand challenge simulations. Rich is the head of the Technology Development Division in the Computational and Information System Laboratory and the NCAR Service Provider Principal Investigator in the Extreme Science Engineering and Discovery Environment (XSEDE). He expanded his work in education and outreach when he established the Summer Internships in Parallel Computational Science (SIParCS) program at NCAR in 2007.
