Hans G. Kaper

 

Greetings and Welcome to My Home Page!

I am an applied mathematician interested in the mathematics of physical systems. My research focuses on the development of analytical and computational methods for differential equations describing these systems.

My current research interest is in the dynamics of Earth's climate system. The textbook "Mathematics and Climate," co-authored with my colleague Hans Engler (Georgetown University), was selected for the "2013 Choice Award" by the Atmospheric Science Librarians International (ASLI) for its "accessible explanations in key areas where climate and mathematics meet." Recently, I have become interested in the concept of resilience and the impact of climate change on human activities, in particular on food systems and food security.

I am Founding Chair of the SIAM Activity Group on "Mathematics of Planet Earth" and co-director of the "Mathematics and Climate Research Network," an NSF-funded network linking researchers across the U.S. to develop the mathematics needed to better understand Earth's climate.

My current academic affiliations are with the Department of Mathematics and Statistics at Georgetown University in Washington, DC, and the University of Illinois at Urbana-Champaign, where I am Adjunct Professor in the School of Music.

I am a Fellow of the Society for Industrial and Applied Mathematics (SIAM), class of 2009, and a member of the SIAM Committee on Science Policy. I currently serve as editor in chief of the monthly newsletter "SIAM News" and as editor in chief of the SIAM Book Series on "Mathematical Modeling and Computation."

I spent most of my scientific career in the Mathematics and Computer Science Division (and its predecessor, the Applied Mathematics Division) of Argonne National Laboratory. I retired from Argonne in December 2008 but retain my affiliation with the laboratory as Senior Mathematician Emeritus.

I have held visiting positions at several universities in the U.S. and abroad, and have served the mathematics community as Program Director in the Division of Mathematical Sciences of the National Science Foundation from 2001 until 2008, with an interruption in 2004-'05.

I reside in Washington, DC. (Note: The District of Columbia is not a state. We have a Representative in the U.S. Congress, who has limited voting privileges. This colonial status is based on the U.S. Constitution, Article 1, Section 8, Clause 17. "Taxation without Representation.")
