23rd Undergraduate Research, Scholarship & Creative Activities Conference WELCOME 2012 Welcome to the 23rd Annual UC Davis Undergraduate Research, Scholarship & Creative Activities Conference, co-sponsored by the Office of the Provost and the Office of the Vice Chancellor for Student Affairs. This year we are proud to showcase the research endeavors of 431 undergraduate students from all academic fields. The conference is designed to acquaint undergraduates with the process and rigors of presenting research in a scholarly manner in an academic setting. This opportunity allows for stimulating interaction between students and an audience of faculty, administrators, peers and family. An added goal is to encourage undergraduates to pursue advanced degrees that will lead to opportunities in research and teaching. At UC Davis, many students have been participating in research that is part of a larger grant where faculty sponsors have given them substantial levels of responsibility to carry out specific components, either individually or collaboratively. Other students have initiated their own projects and have been conducting their research independently under faculty guidance. While many students are reporting on completed projects, some are presenting the latest data on research still in progress. Students present their work at the conference orally, in poster format, or, for the first time this year, as part of an art exhibit. In the oral sessions, students are divided into groups; each student gives a 15-minute presentation that includes a question-and-answer period. A faculty member, who may also serve as a faculty sponsor for one or more of the student-presenters, moderates the session. In the poster sessions, students present a visual representation of their research and discuss the content with circulating conference attendees. The art exhibit highlights creative activity and affords an opportunity to interact with the student scholars who will discuss their creative work with those attending this session. Each student presenter is recognized for his/her contribution to University research by being awarded a certificate as an Undergraduate Research Scholar. We congratulate these students for their accomplishments and hope that this experience helps to launch productive and satisfying academic and professional careers.
