I try to stress to the students that they are responsible for their own education and self worth; that they must invest in themselves and assume responsibility for their personal growth. I emphasize to them that they are not going to learn everything they need to know for their future career in school. The students are here to get the solid educational foundation they can use as a spring board for a successful career. I approach this with the Cedar Crest mission in mind, to help them become leaders in whatever endeavor they choose in life.
Why Cedar Crest?
I realized a long time ago there was a real need to educate students in the sciences who aspired to enter the forensic science field. I taught as an adjunct for several years while still working at the forensic laboratory. I thoroughly enjoyed the experience and realized the impact that I could have on students by sharing my experience, and stressing the importance of a strong scientific education needed for personnel working in the field. Cedar Crest is the perfect setting for forensic science education because encouraging women to pursue science careers is an important part of a skilled, diverse workforce.

"Research in my lab focuses on the use of RNA to examine changes in gene expression in response to environmental stimuli. The tobacco hornworm, Manduca sexta, is the model organism for most of my research projects, but chicken embryos, tomato plants, and human tissues have also been used by my research students. In addition, projects that focus on RNA decay in deposited stains connect my RNA research to the field of forensic science."
K. Joy Karnas, Ph.D., continues her investigation of lipoprotein biosynthesis in the tobacco hornworm (Manduca sexta) through use of an S2 cell system and budding yeast (Saccharomyces cerevisiae) secretory mutants. She has several research projects currently being conducted with Cedar Crest College students.
"My students inspire me. They are the reason that I am who I am, and the motivation for me to do what I do. If I didn’t have such incredible students who truly appreciate the effort that I put into my teaching, I don’t think I would feel as passionate about my teaching and scholarship. Nothing inspires me more than learning that one of my students has achieved more than they thought possible, and words cannot express how much I value letters from alumnae that praise the genetic engineering program and the courses they took at Cedar Crest College."
On Becoming a Teacher
"In my first true teaching experience (beyond simply serving as a teaching assistant and running college biology labs), I discovered my talent for breaking complex concepts down into bite-sized bits that students could comprehend. I have a knack for developing analogies to help students visualize exactly what they are trying to learn. I describe biological concepts in simple, everyday terms, creating a parallel that is easier for novices to grasp. I love teaching the details of molecular genetics-introducing upper-level college students to the intricate world of gene expression-but also enjoy outreach activities that connect me with elementary school classrooms. I am passionate about student centered learning and incorporate classroom discussions, inquiry-based learning, and laboratory activities into my teaching as much as possible. Every time I step into a classroom, my connection with the students helps me rediscover why I love this job."

"Think about the future while you are in the present. While you are in the classroom is to study in order to learn the material and, most importantly, to understand the information. Do not just study to pass the next exam."
Why Cedar Crest?
"My experience as a student at Cedar Crest was exceptional. I loved the tradition, the passion for excellence and the personal relationships I developed with my professors. For me, there was no better place to continue my career. Teaching in one of the best forensic science programs in the country is an honor and a privilege."

"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."

Survey of Organic Chemistry
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."
Why Cedar Crest?
"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."
