ALC's Natural Science & Mathematics Goals

The Natural Science and Mathematics Division offers excellent programs of study. In these programs, faculty work with students in the classroom and individually in order to broaden the students’ view of the world. The Natural Science and Mathematics curriculum allows students to study the scientific approach to learning about the natural world using the problem solving and critical thinking techniques associated with the major areas of science and mathematics, including biology, chemistry, mathematics, physics, and statistics. Since the observable world can be viewed from either the macroscopic, microscopic, or atomic viewpoints, students are encouraged to develop their concrete and abstract thinking and reasoning skills. Many graduates of Alice Lloyd College who receive a degree in science further their education by entering programs in medicine, pharmacy, engineering, dentistry, teaching/education, nursing, physical therapy, and so on. It is the desire of the science and mathematics faculty that students develop an appreciation for learning and so become life-long learners.

Students wishing to seek advanced degrees in medicine, dentistry, pharmacy, engineering, etc. are encouraged to consider the opportunities available through the Caney Cottage Scholarship Program. This competitive scholarship is available to qualifying students who are accepted into graduate or professional schools.

Also, take a look at our Science and Math Brochure (pdf), which introduces you to some of our standout students and relates their experiences at ALC.

Pre-Professional Programs with Transfer Agreements in Engineering and Pre-Pharmacy

To assist students transferring from Alice Lloyd College to professional programs in pharmacy, direct transfer agreements have been established with the University of Kentucky and West Virginia University. Similar agreements to assist students transferring from Alice Lloyd College to professional programs in Engineering at the University of Kentucky, University of Louisville, and West Virginia University have also been established. Students may complete two years of study in Pre-Engineering or Pre-Pharmacy and transfer directly to the chosen university for completion of the appropriate degree in Pharmacy or Engineering. For further details, please contact the Pre-Engineering advisor, Pre-Pharmacy advisor or the Vice President for Academics/Dean of the College. Students interested in these pre-professional programs should establish their program with the designated advisor at the beginning of their studies at Alice Lloyd College

Dr. Paul Yeary

Dr. Yeary graduated from Alice Lloyd College in 1985 with a degree in Math/Physical Science. He went on to receive his Ph.D. in Physical Organic Chemistry from the University of Kentucky. After completing his studies at UK, Dr. Yeary worked for the Teknor Apex Corporation in Brownsville, TN, Remington Industries in Benton, TN, and for the Thomasville Furniture Company/Founders Furniture in Appomattox, VA as a Process Improvement Chemist. Subsequently, in 2000, he accepted a professorship at Alice Lloyd College where he is currently the chair of the Natural Sciences & Mathematics division. 

Along with his duties as Professor of Chemistry, Dr. Yeary serves as the Chair of the Academic Affairs Committee, as well as on the Caney Scholarship and Quality Enhancement Plan (QEP) committees. He is deeply involved in other campus programs and activities. Dr. Yeary is an active and longtime member of the American Chemical Society and has won a number of awards, including the Teaching Excellence & Campus Leadership Award and ALC’s 10-Year Service Award.

Dr. Yeary has co-authored and published two academic papers: “On the Importance of Carbocation Intermediates in Bimolecular Nucleophilic Substitution Reactions in Aqueous Solution” in the Journal of the American Chemical Society (1993) and “Multiwalled Carbon Nanotubes” in Nanomaterials: Inorganic and Bioinorganic (2008). He has also participated in various research activities at the University of Kentucky and has given recent scientific presentations at the Carbon Society Workshop and the International Conference on Carbon (both in Seattle, WA) and at the Appalachian College Association (ACA) Summit. From 2004-2012 he served as a summer research associate with the Center for Applied Energy Research at the University of Kentucky where he worked on a variety of projects in material science.

Dr. Janelle Pryor

Dr. Janelle Pryor serves as Professor of Biology at Alice Lloyd College. She received her bachelor’s degree in biology, graduating cum laude, from Muskingum College (New Concord, Ohio) in 1984.  She also received minors in Chemistry and Computer Science. An excellent student, Dr. Pryor was a member of the Beta Beta Beta Biology Honor Society. Two years later, she went on to garner a master’s degree in Botany from Ohio University, as well as earning a Ph.D. in Environmental and Plant Biology.

Dr. Pryor completed additional graduate coursework at Mississippi College and earned a second Ph.D. in Physiology and Biophysics from the University of Mississippi Medical Center.  She is a proud member of the Phi Kappa Phi Interdisciplinary Honor Society.

She is active in campus activities in which she is a faculty sponsor of the Allied Health Club and the IMPACT Club.

Dr. Robert Hamilton

Dr. Hamilton serves as Professor of Biology in the Department of Natural Sciences and Mathematics at Alice Lloyd College. He received his bachelor’s degree in Ecology from the University of Guelph in 1986. Dr. Hamilton received his Ph.D. in Botany from The Ohio University in 1991. He served as an assistant professor, associate professor and professor of biology in the Department of Biology at Mississippi College from 1991 through 2009. Dr. Hamilton has served as Professor of Biology at Alice Lloyd College since 2010.

Dr. Hamilton has published 19 papers in peer reviewed journals and symposia. He has conducted 10 workshops for high school teachers in the area of Molecular Biology and Ecology. He has mentored dozens of undergraduate and graduate student researchers. Dr. Hamilton has authored 3 successful grant applications to the National Science Foundation and participated in a successful grant application to the Howard Hughes Medical Institute. He has made dozens of presentations of his scientific work to academic societies and symposia. Dr. Hamilton has also served on the education committee of the Ecological Society of America, served as a Biology Councilor for the Council on Undergraduate Research, and served as chairperson and vice chairperson of various sections at the Mississippi Academy of Sciences on numerous occasions.

Dr. Sigrid Greene

Dr. Sigrid Greene is an Assistant Professor of Physics at Alice Lloyd College. A German national, she was born and raised in Germany, finishing high school in her hometown of Guetersloh (in Northrhine-Westfalia) before going to college at the University Osnabrueck (in Lower-Saxony). She received her undergraduate degree in physics (Diplom) from that institution in 1996. To be awarded this degree, a one-year research work was required. The research was performed while a guest at the University of Hawaii at Manoa.

Dr. Greene returned to Hawaii as a graduate student and was awarded a Ph.D. in Physics in 2003. Her research was in the area of computational physics, studying the growth of Boron-nitride clusters from first principles.

Dr. Greene has previously taught introductory physics courses at the University of Texas in San Antonio. She is now teaching Conceptual Physics as a general education class (PHYS 101), algebra-based physics for biology majors (PHYS 211/212), and calculus-based physics for pre-engineering majors (PHYS 231/232), as well as the associated labs. She has also taught the Introduction to Astronomy general education class (AST 101) and lab in previous semesters.

Last year, Dr. Greene became a member of the American Association of Physics Teachers, with an interest in the results of physics education research into how to aid students in internalizing the beautiful concepts and ideas of physics, as well as the paper-and-pencil strategies of actual problem-solving.
