Student Information


Who Teaches QSci Courses?

Courses offered through the Center for Quantitative Science are largely taught by faculty from the School of Environmental and Forest Sciences and the School of Aquatic and Fishery Sciences. One characteristic that the professors and teaching assistants in CQS all have in common is that their research involves the application of quantitative methods to biological problems.  Therefore, in addition to being biologically knowledgeable they also have degrees in biostatistics, biophysics, mathematics, the management of resources, or other professionally related areas.  One consequence of their experience and training is that they bring a realistic sense of the methods that are important for students to know and they have the ability to extract from their years of experience relevant problems that are meaningful to large numbers of students in the class.

For information on individual instructors, see CQS Faculty.

Is This Really Math/Statistics?

Biological science and resource management have a long history, extending beyond the classical Greek and Roman civilizations. The Egyptians manipulated their crops and fertilized their land through the annual flooding of the Nile River, and the Greeks developed the methods for plotting out geometrical shapes for farm boundaries and for city planning. The Romans developed these further and built roads and laid out land and farm patterns that still exist. Throughout this entire period of time, the management of resources was recognized to rest both on biological science (how did crops and forests grow) as well as upon the need to quantify rates and amounts of growth and the land that was devoted to growth. These same very fundamental ideas are seen today, but in far more sophisticated forms. Many of the problems of today in the management of resources and the study of biological science still concern the rates of growth and the need to test hypotheses about how growth occurs and whether to use pesticides, how much fertilizer to use, age of sexual maturity, etc. In the modern world it is virtually impossible to practice biological science at either the molecular or ecological level or to practice resource management without a knowledge of statistics or without a knowledge of rates of growth, which falls into the area of calculus. The two most basic forms of statistics, as we teach them in the Center for Quantitative Science, are testing of hypotheses for whether one treatment or another works, and regression in order to be able to make predictions as to whether something will work or not. The Center for Quantitative Science teaches such basic courses two times a year, and in addition it also teaches classes concerned with how to design experiments and how to sample, in order to collect data. The point to get from this short history is that it is not really practical to separate out biological science and resource management from mathematics and statistics. They were linked centuries ago and continue to be so. The proof is in the history, but furthermore, the proof is in the future. Those people who are students today will be practicing professionals for the next two to three decades, and it is for those people that we design our classes.

Computing

Computer Access in the School of Aquatic and Fishery Sciences

The computer classroom in room 207 Fishery Sciences Building (FSH) is available for student access, except on rare occasions when a class is being taught in the room. This PC lab is equipped for general computational needs including email, word processing, database manipulation and compilation, and course work software.

Computer policies are posted on the SAFS website (http://fish.washington.edu). The site also includes hours when the computer room is scheduled for classroom instruction and unavailable to students. Software in room 207 is listed.

Computer Access in the School of Environmental and Forest Sciences

The School of Environmental and Forest Sciences has a student computer lab in Bloedel 156. The room is open and available for student use Monday through Friday from 8:00 a.m. to 5:00 p.m.  The Dell machines are loaded with most of the software students would need. A CFR Net Id is needed to use the computers in this room. To obtain a CFR Net Id please contact Shane Krause (skrause@u.washington.edu), 206.616.5414, Bloedel 156.
