At some colleges and universities, students are crammed into huge auditoriums for classes, where they’re taught largely by teaching assistants. Not at Cedar Crest College. Here, you will learn in a small-classroom setting from knowledgeable and experienced professors who will quickly get to know your name, and help you find success.

Jeanne Berk, Ph.D. is an assistant professor of chemistry at Cedar Crest. Her research as a graduate student was based on a new class of polymers called Dendrimers, which she synthesized and then studied their physical properties in solution. She moved to the Lehigh Valley after graduate school and worked as an adjunct instructor at local colleges and universities until finally settling into a position at Lehigh University. There, Berk acted as their first undergraduate laboratory manager, teaching and helping them redevelop their general chemistry laboratories into an inquiry based format. She left Lehigh and joined the Cedar Crest community in order to get back to teaching organic chemistry.
Berk is a member of the American Chemical Society, Alpha Chi Sigma (Professional Chemistry) and Sigma Xi.
“The environment. I first found Cedar Crest College as an adjunct teaching over the summer, but I found myself wanting to teach here more and more. So when the organic chemistry position finally opened I had to apply. Some of my closest friends graduated from Cedar Crest College, so I am honored to be here continuing their legacy and they are thrilled I could be part of their experience. The faculty and staff are inspiring and the students truly want to learn and be involved. What more could you ask for?”
“College is your chance to explore, so make the most of it. If you read a class description and it sounds fascinating, try taking it. Also check out the travel abroad opportunities. It can truly open your eyes. They will all be things you'll treasure from your college experience.”
“After getting my undergraduate degree I had planned on going out into the industrial market, but the job market was bad I decided to go on and get my Masters degree. I left Ohio and ended up in New Jersey, a whole new world. As a graduate student I worked as a teaching assistant (T. A.) in the organic labs and teaching recitations. Students kept telling me that I explained things clearly and their "Aha" moments were pure chemistry for me. I found that the idea of working in a lab became less and less appealing and that teaching was what I wanted. I never looked back, and continued on for my Ph. D. so I could teach.”

The Kieber-Emmons research lab works on frontier problems in metalloprotein mechanism related to bioenergetics and regulation of bioenergetic machinery. The long-term goal is to use what we learn about how these metalloproteins work to develop new molecules and methodologies as solutions to problems in health and energy.

Thomas H. Pritchett
B.S. in Chemistry and Computer Science, Murray State University
M.S. in Chemistry, Murray State University
Instrumental Analysis Laboratory
Before joining Cedar Crest in 2003, Thomas Pritchett worked both as an analytical chemist and as an environmental chemist for 21 years. His work included running the GC/MS support laboratory at Murray State University, working in the Superfund program for the U.S. EPA, and working as an environmental consultant. During that time, he taught numerous short courses on subjects ranging from the use of field analytical instrumentation in soil gas investigations, to the use of optical remote sensing equipment for the determination of emission rates, to fence line monitoring at hazardous waste excavations. As of summer 2011, Thomas Pritchett has presented 25 papers at national or regional meetings of professional societies and has been a co-author on 51 additional papers at such conferences. Current research interests involve the application of emerging analytical techniques to the field of forensic science and determination of the uniqueness of partial fingerprints, and the probability of errors in a match of a partial print to a known full print.

"You should never stop learning. A college education is less about learning new facts and more about building a foundation of knowledge and skills upon which one can continue their learning after graduation. After graduation life will periodically present you new challenges that will require you to teach yourself new knowledge and skills. Those who can meet those challenges will advance in their careers while those who cannot will stagnate. In the sciences, this is ultimately what will determine whether you will become a true scientist or just a mere technician."

Marianne Staretz, Ph.D., did her doctoral research on the mechanism of the colchicine-tubulin interaction in relation to cancer. A multi-disciplinary approach combining the techniques of organic synthesis, medicinal chemistry and biochemistry was used. She went on to do postdoctoral research at the American Health Foundation, a non-profit research institution dedicated to disease prevention. Her research focused on the effects of isothiocyanates, dietary inhibitors of carcinogenesis, on the metabolism of and formation of DNA adducts by carcinogenic tobacco-specific nitrosamines and benzo(a)pyrene. Staretz has continued some of the cancer prevention research at Cedar Crest College by examining the cancer prevention mechanism of organoselenium agents. She has also expanded some of the toxicology experience gained at the American Health Foundation into the area of forensic toxicology and has several ongoing research projects in this area.

"I don't think students realize as they are progressing through their years of college how valuable the experience actually is. The goal is not just to get that degree. You will actually use what you are learning here—so work hard to learn as much as you can. The greater the effort you put into it, the greater the rewards will be."
"I have always wanted to teach at a small liberal arts college where teaching is the focus of the college. Cedar Crest College certainly fits in that category. On my first visit to Cedar Crest, I became aware of a faculty dedicated to teaching and knew that I wanted to be a part of that faculty. I am surrounded by some very talented teachers and scholars and it is a privilege to be a part of that community. Being part of the family of women scientists, it is also a pleasure to be involved in the education of future women scientists and contribute to the growth of this family."
