STUDENT RESEARCH SYMPOSIUM 2012 6 March 9, 2012 Dear Colleagues and Guests: It is with great pleasure that I welcome you to the San Diego State University 2012 Student Research Symposium. The symposium is a university-wide event to recognize and celebrate the outstanding research and creative endeavors of our undergraduate and grad- uate students. The symposium also identifies our most talented students who will represent SDSU at the annual California State University Student Research Competition. More than 400 students, representing our many outstanding ac- ademic programs, are presenting their original scholarly work. Moreover, the symposium provides a venue for sharing our dis- coveries broadly, demonstrating our commitment to research that benefits our region, nation, and world. Together, these activities advance our vision of San Diego State University as a leading public research university. To plan and execute an event of this magnitude required the efforts of dedicated faculty and staff members. In addition, more than 250 judges have volunteered to share their time and expertise in evaluating oral and poster presentations. These collective efforts demonstrate our commitment to fostering student scholarship and professional development, and I am grateful to all who have worked so hard on behalf of our students and the university. Sincerely, WELCOME FROM THE FROM PRESIDENT WELCOME Elliot Hirshman, President San Diego State University STUDENT RESEARCH SYMPOSIUM 2012 7 Thursday Afternoon, March 8, 2012 Saturday Morning, March 5, 2011 S 1:00 pm – 4:00 pm Registration 7:00 am – 10:00 am Registration LA 1103 Tutoring Center LA 1103 Tutoring Center NT E Friday, March 9, 2012 E Session 7:00 am – 4:00 pm Registration 9:00 am – 10:30 am Oral Presentations LA 1103 Tutoring Center LL and LA Opening Remarks F Session 8:30 am – 9:00 am LL 108 10:45 am – 12:00 pm Oral Presentations Elliot Hirshman LL and LA President, SDSU A Sessions 12:00 pm – 1:15 pm 9:00 am – 10:45 am Oral Presentations Reception North side, Love Library LL and LA 9:00 am – 10:45 am Poster Presentations 1:30 pm – 2:30 pm Library Dome Awards Ceremony SCHEDULE OFSCHEDULE EV B Sessions LL 108 Keynote Speaker 11:00 am – 12:45 pm Oral Presentations Stephen Welter LL and LA Vice President, Research 11:00 am – 12:45 pm Poster Presentations SDSU Library Dome C Sessions 1:00 pm – 2:45 pm Oral Presentations LL and LA LL = Love Library, Main Building 1:00 pm – 2:45 pm Poster Presentations LA = Library Addition Library Dome D Sessions 3:00 pm – 4:45 pm Oral Presentations LL and LA 3:00 pm – 4:45 pm Poster Presentations Library Dome STUDENT RESEARCH SYMPOSIUM 2012 LL = Love Library, Main Building LA = Library Addition 8 Thursday, March 8 1:00 pm – 4:00 pm Registration LA 1103 Tutoring Center Friday, March 9 7:00 am – 4:00 pm Registration LA 1103 Tutoring Center Opening Remarks 8:30 am – 9:00 am Elliot Hirshman, President, SDSU LL 108 Session Session Time Session Title Presentation Location Number Type 9:00 A-1 Oral Evolutionary Biology LA 2203 A-2 Oral Analytical Chemistry LL 430 A-3 Oral Graduate Research in Biotechnology LL 431 A-4 Oral Undergraduate Research in Environmental Biology LL 410 A-5 Oral Behavioral issues in Organizations LL 260 A-6 Oral Earthquakes and Tsunamis LL 261 A-7 Oral Public and Environmental Health LA 76 A-8 Oral Culture, Ethnicity,and Discrimination LA 78 9:00 A-12 Poster Enviroscience Library Dome A-13 Poster Public Health Library Dome A-14 Poster Stem Cells Library Dome A-15 Poster Computational Genomics Library Dome A-16 Poster Status.
