2008 Janet Andersen Lecture Award Winners

Congratulations to Professors Jeff Wilkerson and David Hall who were selected as the 2008 Janet Andersen Lecture Award winners. Jeff Wilkerson is a physicist at Luther College and David Hall is a biochemist at Lawrence University.  As part of the award, each of them will present a keynote address at this fall's Undergraduate Research Symposia.

Jeff Wilkerson, PhD
Associate Professor of Physics
Luther College, Decorah, IA

  Jeff Wilkerson is the winner of the 2008 Janet Andersen Lecture Award and will present a keynote address at this fall's Physical Sciences andMathematics Undergraduate Research Symposium at the Washington University on Oct 31 - Nov 2.

Professor Wilkerson joined the Luther College physics department in the Fall of 1997. He received his B.S. in Physics from Indiana University, and has his Ph.D. in physics from the University of California, Berkeley

Jeff currently has two primary areas of research interest. 

  • (1) Study of the use of gaseous xenon as a detector medium for hard x-rays. Hard x-ray detectors are used to study black holes, neutron stars and active galactic nuclei. In xenon gas the energy of an incident x-ray gets converted to scintillation light, the strength of which is proportional to the energy of the x-ray absorbed. In the laboratory we have been studying this process.
  • (2) Development of rapid photometric techniques for the study of stellar signal variations. We acquire hundreds or thousands of images of a rich star field in a given night. We then perform a statistical analysis of the signal (= "apparent brightness") of each star in the field over the course of the night. While this work should prove useful for the study of everything from meteors to near-earth asteroids to variable stars, we are primarily interested in searching for foreground objects that pass between us and a distant star, leading to a sudden and brief decrease or increase in the flux measured from the background star.

Concerning his approach to engaging undergraduates in research, Jeff wrote, "I don't create separate research problems for students. They join me in the lab working on the projects I am tackling at the time.  It's a difficult task for the students but I think the rewards are great as well. In an ideal situation I will work with a student during the summer after the sophomore year and continue to work with the same student until graduation. This approach allows us to start with simple data acquisition or analysis, instrument construction or calibration, or software development. Over the course of time we can introduce the different aspects of the project, allowing the student to slowly grow until the project is his or hers."

His nominee wrote, "I brought Jeff into my classroom last January to make a presentation on the origin of the universe for my ‘Great Ideas in Natural Science' course for non-majors. It was the best class of the term. A very bright senior came to me afterwards and said that Jeff's talk was the most engaging intellectual experience of his four years at Luther College. Last fall Jeff made a presentation of some of his research as a visiting speaker at the University of Minnesota, Mankato. I called the organizer of the visit and asked how it went. The organizer said that it was a terrific lecture that successfully engaged the entire audience, including undergraduates, graduate students and faculty. He said, ‘it would have been impossible to go to sleep during the presentation, and no one did.' "


Biological Sciences and Psychology
2008 Janet Andersen Lecture Award Winner

David J. Hall, PhD
Associate Professor of Chemistry
Lawrence University, Appleton, WI

David Hall is the winner of the 2008 Janet Andersen Lecture Award and will present a keynote address at this fall's Biological Sciences and Psychology Undergraduate Research Symposium at the University of Chicago on Oct 31 - Nov 2.

Prof. Hall joined the chemistry department at Lawrence in the fall of 2002. After completing his Ph.D. in the Department of Biochemistry at The University of Wisconsin, Dave spent three years as a visiting professor at his alma mater, Butler University. He then returned to Madison for post-doctoral research in the department of Biomolecular Chemistry in the UW Medical School. Dave's primary teaching responsibilities include Biochemistry and Advanced Biochemistry along with contributions to the teaching of introductory and organic chemistry courses.

Dave's current research interests focus on signal transduction pathways activated by viral infection.  Dave's research, as he describes it, represents an effort to understand the mechanisms by which rhinovirus activation of macrophages leads to the exacerbation of asthma. His research is based on the conviction that, because virus-induced asthma has been resistant to therapy, it is important to expand our knowledge concerning the critical cellular and physiological processes involved in its development, so that new forms of intervention might be found.

According to the nomination letter, "Dave seems to me to embody all the requisites of the award. He is active in research, he is a remarkable mentor and advisor to his research students, he is a vocal proponent of both the chemistry and biochemistry areas of our department, and while his primary research area is in biochemistry, he has been willing and able to lead a variety of efforts in interdisciplinary areas, most notably our nanoscience initiatives. He is also a creative and popular teacher, an excellent and enthusiastic speaker who would represent well the undergraduate institutions of the consortium on the program of one of the research symposia."
