April 16: Destruction of computer science/engineering at University of Florida
From: Tim Davis <firstname.lastname@example.org>

Subject: Destruction of computer science/engineering at UF
Many of my colleagues have been asking about this concern, having seen it in the news or from other colleagues.
My department needs your help. Please see http://saveufcise.wordpress.com/ for more details.
The Dean of the College of Engineering has proposed the destruction of my department (the Computer and Information Science and Engineering department at the University of Florida).
About half the faculty would scatter to 3 other departments, along with its PhD program and one MS program. The BS and MS in Computer Science would remain in the burnt ashes of a CISE department, dedicated solely to teaching. Faculty not chosen by other departments would lose their research. Courses taught for the PhD program would become service courses taught by non-research faculty.
This is at the same time that the computing discipline is increasing in Florida and in Gainesville itself.
Please consider the facts posted at http://saveufcise.wordpress.com/ (including our Dean's proposal), and sign our petition. The Dean's drastic reduction is under the guise of a budget reduction (2% cut to the departments, all borne by our department), and a 'reduction of duplication'. The change would actually increase duplication, because the MS in Computer Engineering would move to another department, while the MS in CS would remain in CISE.
If these changes go through, and I remain at CISE, my NSF-supported research in sparse matrix algorithms, including x=sparse(A)\b in MATLAB, would disappear. Other NSF-supported research would also evaporate.
Please support our petition, and consider contacting our president to oppose our Dean's plan (email@example.com).
