Bynthia Anose

Started at Bethel in 2004

Education: B.S., Bethel University; Ph.D., University of Minnesota

Research interests: Anose's research interests include the study of potential biomarkers for human reproductive cancers. Her primary area of investigation is prostate cancer (PCa). The goal of her current work is to investigate the effects of flutamide (a clinical anti-androgen) and dihydrotestosterone (an androgen) on the expression of ZEB-1 (zinc finger E-box binding homeobox-1). Ongoing studies aim to confirm the feasibility of using ZEB-1 as a PCa metastatic biomarker, utilizing the cutting-edge biochemical technique known as real-time polymerase chain reaction.

Rollin King

Started at Bethel in 2001

Education: B.S., Huntington College; Ph.D., University of Georgia

Research interests: King's research in the area of computational quantum chemistry involves a mixture of mathematics, physics, chemistry, and computer science. His current research topics include elucidating radical co-polymerization reactions and solvent effects on the optical rotation of chiral molecules. Collaborating with colleagues around the country, he is a primary developer of the PSI quantum chemistry software program.

Ashley Mahoney

Associate Department Chair

Started at Bethel in 2001

Education: B.S., Angelo State University; Ph.D., University of Kentucky

Trey Maddox

Started at Bethel in 2008

Education: B.S., University of West Florida; Ph.D., Emory University

Research interests: Maddox's research focuses on two classical areas of organic chemistry, synthesis and natural product isolation. His main project focuses on the synthesis of modified DNA and RNA nucleosides. These modified nucleosides can be used to study template directed polymerization, the core mechanism in DNA replication, transcription, and translation. His newest project is developing protocols for the isolation and identification of biologically active compounds in different herbal remedies that have been used by different cultures for centuries. This research aims to identify previously unknown compounds that demonstrate important biological activity.

Matthew Neibergall

Started at Bethel in 2007

Education: B.S., Bethel University; Ph.D., University of Minnesota

Research interests: Neibergall studies the mechanisms by which oxygenase enzymes activate O2 for insertion into organic compounds during cellular metabolism. The formation of DNA nucleotides from their RNA nucleotide precursors, the conversion of the amino acid phenylalanine to tyrosine and then to the neurotransmitter dopamine, and the production of prostaglandins are biological pathways that require oxygenase enzymes. Currently, his research group is studying nitrobenzene-1,2-dioxygenase, a Rieske non-heme iron oxygenase isolated from a soil bacterium that degrades the priority pollutant nitrobenzene. They apply a broad array of techniques in order to obtain mechanistic information, such as recombinant DNA technology, protein expression and purification, enzyme kinetics, chromatography, as well as several spectroscopic techniques.

Wade Neiwert

Department Co-Chair

Started at Bethel in 2004

Education: B.S., George Fox University; Ph.D., Emory University

Research interests: Neiwert's research focuses on the study of a unique class of inorganic cluster-like compounds known as polyoxometalates (POMs for short). His recent efforts have focused on using POMs as nanoscale building blocks, where they are connected by organic ligands, resulting in inorganic-organic hybrid materials. Multiple spectroscopic techniques are used to characterize POMs and their resulting polymeric materials, including multi-nuclear NMR (1H, 13C, 31P, 29Si, etc), FT-IR, UV-Vis, and single crystal X-ray diffraction.

Ken Rohly

Started at Bethel in 1987

Education: B.S., Spring Arbor University; Ph.D., University of Pittsburgh

Research interests: Rohly's research has focused on materials chemistry issues as they relate to industry. One of his interests has been the modification of the surface chemistry of metallic biomaterials used for devices implanted in the body. He's also researched the catalytic breakdown of poly(ether urethanes) and the composition and thermal stability of silicone oils. He's contracted with Medtronic, Deluxe Corp., and 3M.

Jack Waas

Started at Bethel in 1987

Education: B.A., Swarthmore College; M.S., University of Michigan; Ph.D., University of Michigan

Research interests: Waas's research interests lie in organic reaction mechanisms and methodology. While it's important to prepare useful and interesting new compounds, Waas is exploring what we can learn about the mechanisms of the reactions that form such compounds. Investigations into such questions can gain us deeper understanding into new syntheses or new synthetic methods. Using both experimental and computational methods, he attempts to gain insight into the kinetics and thermodynamics of reactions for which the mechanism is unclear or unexamined. An ongoing collaboration with Dr. Daniel Singleton at Texas A&M University has provided ongoing projects involving cyclizations with multiple reaction pathways.

Brandon Winters

Started at Bethel in 2011

Education: B.A., University of Minnesota, Morris; Ph.D., University of Minnesota

Research interests: Winters' research focuses on understanding the internal chemistry of soot particles and developing better understandings of their various interactions in the atmosphere. Aerosol particles are solid or liquid particles suspended in the gas phase. They can be naturally occurring or man-made and they are involved in myriad chemical reactions in the environment, not the least of which is the interaction of soot particles with water vapor in the atmosphere. Being very complex in chemical structure, soot particles and their atmospheric interactions are not well understood. They contribute in complex ways to things like atmospheric temperature, global and regional precipitation trends, and acid rain. Winters' primary methods of investigation include FTIR and Raman spectroscopy, electron microscopy, and tandem differential mobility analysis (t-DMA).
