Student Research

Â鶹´«Ă˝ Department of Computer Science faculty have integrated students into their research programs in a variety of ways. Some of undergraduate students have participated in REUs (research experience for undergraduates), capstone projects and independent research that has resulted in scholarly publications with their faculty mentors.  

Graduate students have been hired as research assistants to work with faculty on research grants and have collaborated with faculty mentors as part of research courses. Many students have had opportunities to travel to conference and present their work.  Our faculty are always looking for students to work with them.
