COMP 3550: Introduction to Bioinformatics
This course can meet one of the elective requirements for the Smart Systems Stream.
This course is designed as an interdisciplinary introductory course in bioinformatics for both Computer Science and Biology students and as a bridge between both disciplines. The course is intended to be a course for a mixed audience of students with different backgrounds (e.g. computer science and biology). The course will focus on the fundamental concepts, ideas and related biological applications of existing bioinformatics tools. The purpose is to provide the students with hands-on experience on the major computational approaches applied to a wide variety of bioinformatics problems.
|Lab||In addition to classes, this course has one structured laboratory session per week.|
Prerequisites: Biology 1001; one of COMP 1001, COMP 1002 or COMP 1510; and 6 credit hours in Computer Science or Biology course at the 2000 level or above, excluding Biology 2040, 2041, 2120; or permission of the course instructor
Availability: This course is usually offered once per year, in Fall or Winter.
Bioinformatics deals with the development and application of computational methods to address biological problems. The course will focus on the fundamental concepts, ideas and related biological applications of existing bioinformatics tools. This course will provide hands-on experience in applying bioinformatics software tools and online databases to analyze experimental biological data, and it will also introduce scripting language tools typically used to automate some biological data analysis tasks.
Biology students will appreciate the impact of these approaches for addressing biological questions and will gain insight on the limitations and strengths of these approaches. Computer Science students will appreciate the practical use of the concepts they have been taught in other courses, but most importantly, the challenges posed by biological questions, and the need for the robust algorithms that deal with the very large, noisy datasets typically present in biology. Computer scientists and biologists will both recognize the large diversity of questions addressed by bioinformatics applications. Many industry and research jobs now require cross-disciplinary collaboration. With this course, students will start becoming aware of the interdisciplinary nature of bioinformatics and appreciate the contribution of people outside their field of study.
