          Professor John Nagle has taught many courses in the Physics Dept., including Introduction to Biophysics, which attracted students from Biological Science, Physics and Engineering, and Special Topics in Statistical Mechanics. Professor Nagle is now Emeritus from teaching in the classroom, but he still teaches a reading class as well as Introduction to Research for graduate students.  Prof. John Nagle also directs graduate students in Research 33-776.


            Research Professor Stephanie Tristram-Nagle teaches undergraduates how to conduct research in Biological Physics.  The course is 33-350 (sophomores and juniors), and 33-451 (seniors), Research for Undergraduates.  As many as 36 credits may be taken during the undergraduate career, but only 9 credits may be used as a Physics elective.  Emphasis is on data analysis of x-ray synchrotron data collected at the Cornell High Energy Synchrotron Source (some students have even participated in the data collection!), and experiments at CMU including sample preparation, density measurements, circular dichroism spectroscopy and X-ray experiments at CMU.  In addition, literature searching and reading of scientific papers are required.  Depending on the quantity and quality of the experimental results, research papers are written with the undergraduates included as authors and submitted to scientific journals.  In three past cases, undergrads have presented their research at the national meeting of the Biophysical Society.  Special permission for this course must be obtained in advance from Prof. Kunal Ghosh.  Prof. Tristram-Nagle is a former member of the Department of Biological Sciences and a current member of the Physics Department. Prof. Tristram-Nagle also teaches Introduction to Graduate Research in the spring semester and directs graduate student Research 33-776.
