Computer Science Department (CS)
You don’t have to be an expert with computers to be a computer science major! However, if you are a logical thinker and like to solve problems this may be the major for you. The curriculum for a computer science major at UW-La Crosse is both exciting and demanding. What will you do with the knowledge you’ve learned? You will become a world class problem solver. After learning the fundamental material in computer software, hardware and the theory of computing, you will be finding ways to make life better for people. Software is an integral part of our society in both visible and invisible ways. Take a look at some of the modern conveniences of our life; iPods, cell phones, video games, medical imaging systems, and engines. As you can see, the way we interact with information through software leaves very little that computer science does not touch.
With that said, we think there is no better place to pursue your degree than UW-La Crosse. Small class sizes and accessible professors give students a level of attention not available on larger campuses. We have outstanding faculty who have many different interests, but who all share a love for teaching. A history of talented students, great facilities and undergraduate research opportunities, make for an ideal learning environment. The Department of Computer Science at UW-La Crosse is the second oldest in Wisconsin, only behind Madison, and has a fine reputation within the computing industry during the past 40 years.
The job market for computer scientists has always had plenty of opportunities and the demand continues. The National Bureau of Labor Statistics, in its rolling ten-year horizon Occupational Outlook Handbook, consistently projects the software industry to be among the fastest growing sectors of the economy.
