Important Notice

This web site will be shut down permanently on July 1, 2026, when I retire from Colorado State University. For those of you who have been using the Chemkin calculation tools, they cannot be transferred to a different server maintained by another individual. I was permitted to host these calculators because I was one of the (minor) authors of Chemkin II, and Sandia allowed me to offer them subject to some restrictions. Since January 2010 the calculators have been used successfully more than 730,000 times, with the equilibrium calculator being the runaway favorite, and the homogeneous chemical kinetics calculator the least used (zero times, in fact).

Welcome!

This is the site of the Dandy research group at Colorado State University. Our research activities focus on the design, development, and implementation of micro-total analytical systems (μTAS). Application areas include (1) environmental monitoring of water quality, (2) self-contained field portable devices for multiplexed pathogen detection and identification, (3) airborne sampling of virus and fungi, (4) biomarker sampling from organotypic tissue slices, and (5) improved trauma patient care between field and hospital.

In addition to the Department of Chemical and Biological Engineering, our group is closely aligned with research in the School of Biomedical Engineering, and we offer graduate degrees in chemical engineering and bioengineering.
