UNIVERSITY OF WASHINGTON’S Fifth Annual Undergraduate Research Symposium A Celebration of Undergraduates in Research Fostering a Community of Student Scholars in the Arts, Sciences, Social Sciences, Technology, and Humanities UNI UNIVERSITY OF WASHINGTON’S Seventh Annual Undergraduate Research Symposium A Celebration of Undergraduates in Research 14 May 2004 MARY GATES HALL 12:00 – 5:00 PM PROCEEDINGS Sponsors: The UW Office of the President, Office of the Provost, Office of Research , Office of Undergraduate Education and the Undergraduate Research Program The Seventh Annual Undergraduate Research Symposium is organized by the Undergraduate Research Program (URP), which facilitates research experiences for undergraduates in all academic disciplines. URP staff assist students in planning for an undergraduate research experience, identifying faculty mentors, projects, and departmental resources, defining research goals, presenting and publishing research findings, obtaining academic credit, and seeking funding for their research. Students interested in becoming involved in research may contact the URP office in Mary Gates Hall Room 310 for an appointment or send email to [email protected]. URP maintains a listing of currently available research projects and other resources for students and faculty at: www.washington.edu/research/urp.

ANNOUNCING NEW OPPORTUNITIES FOR UNDERGRADUATE RESEARCH! Research Fellowships for Advanced Undergraduates Sponsored by the Washington Research Foundation and UW Undergraduate Research Program These new $5000 fellowships support undergraduates who have shown promise as dedicated and creative researchers to continue their work in a science or engineering field throughout the academic year 2004- 05. Students who plan to graduate no earlier than June, 2005 and who have completed at least three quarters of research are encouraged to apply. Applications are due June 4, 2004. For more information visit the Undergraduate Research Program website: www.washington.edu/research/urp/rfau.html. Travel Awards for Undergraduates to Present Research Sponsored by the UW Office of Research, Undergraduate Research Program and the Mary Gates Endowment for Students These new awards help make it possible for undergraduates to extend their research experience by contributing to important discussions of current research at professional conferences. Students who have had a paper or poster accepted to a conference may apply for funding for travel expenses and registration fees. Applications are accepted on a continuing basis. For more information visit the Undergraduate Research Program website: www.washington.edu/research/urp/urta.html. POSTER SESSIONS PLEASE NOTE Abstracts are listed alphabetically by the presenter’s last name, unless otherwise noted. STUDENTS HONOR THEIR MENTORS “This research project would not have been possible without the help of Professor Mark Holmes, who tirelessly worked to clarify the murky and illuminate the indecipherable. Also, Prof. Chuck Nittrouer has been very kind in lending both his expertise and equipment to this study.” - Maureen Davies, Senior, Earth and Space Sciences Mentor: Mark Holmes, Oceanography “Professor Batya Friedman saw potential in me that no one else, including me, saw. Before being invited by Prof. Friedman to do research in her lab, I was unsure of my specific interests in my major. Now, in my third quarter with her, she has encouraged and challenged my thoughts and ideas. I truly appreciate the opportunity she has given me to expand my knowledge in such a creative way.” - Robin Sodeman, Senior, Informatics Mentor: Batya Friedman, Information School “I would like to thank Professor Nikhil Singh for providing immense help with my research project by pushing me to go further than I first thought I could go.” - Doug Jensen, Senior, History Mentor: Nikhil Singh, History !
