Proceedings of the 24th Annual Biochemical Engineering Symposium

The 24th Biochemical Engineering Symposium was held 9-10 September 1994 at the YMCA of the Rockies conference center in Estes Park, Colorado, under the sponsorship of the Department of Chemical Engineering at the University of Colorado. Previous symposia in this series have been hosted by Kansas State University (1st, 3rd, 5th, 9th, 12th, 16th, 20th), University of Nebraska-Lincoln (2nd, 4th), Iowa State University (6th, 7th, 10th, 13th, 17th, 22nd), University of Missouri-Columbia (8th, 14th, 19th), Colorado State University (11th, 15th, 21st), University of Colorado (18th), and the University of Oklahoma (23rd). The next symposium is scheduled to be held at the University of Missouri-Columbia. The symposia are devoted to talks by students about their ongoing research. Because final publication usually takes place elsewhere, the papers included in the proceedings are brief, and often cover work in progress.
