TEACHING PHIOLOSOPHY

Coming to University is an exciting period in a student’s life. He/she is about to experience a number of things for the very first time, foremost of all is their chosen Major! I believe in  encouraging student not only to learn the subject matter but also to critically interpret and examine the underlying data: in other words to think about the subject. While knowledge is a fundamental requirement in all academic situations, later on it is the ability to think laterally and apply the knowledge gained during the student’s formative years that is ultimately important in the future career of the graduating student. I bring this to the fore both in the class setting and when I mentor students in one-to-one situations. My door is always open to students so that I may help them in any way I can.

General Research InterestS

Molecular basis of cancer.

Control of transcription mediated by nuclear hormone receptors, coregulators and chromatin structure.

Mechanisms of DNA damage induced by polyaromatic hydrocarbons

Muscle cell differentiation

Molecular evolution of protein-protein interactions

Current program: Characterization of the Transforming Acidic Coiled Coil (TACC) gene family.

In 1998, I discovered and published a new family of proteins that are important in the development of cancer. From 2000-2006, my research team (at Roswell Park Cancer Institute) explored the role of these Transforming Acidic Coiled Coil proteins in the interphase nucleus, and the role they play in cell cycle checkpoint activation that occurs during DNA damage. These goals are being furthered here to provide a coherent picture of how dysregulation, alteration of splicing patterns or mutations of the TACC genes adversely affects normal cellular metabolism and contributes to the development and progression of cancer.

UNDERGRADUATE RESEARCH STUDENTS SUPERVISED (Arkansas Tech).

Mentored research is important in the development of future graduate and medical students. So every Fall and Spring semester I encourage one or two junior or senior students to participate in my TACC-related projects. These projects have ranged from exploring the use of the Affymetrix Exon array to identify novel breast cancer biomarkers, to targeted knock-out of genes in muscle cells. More recently, we have opened up collaborations with Dr. Gavin Jones in the Department of Chemistry to test the anticancer activity of newly made organic compounds. Research projects of this nature underlie medicine and the pharmaceuticals industry and show the intimate relationship between chemistry and biology. These research projects have been funded by the generous support of the ATU undergraduate research program and the Arkansas Space Grant Consortium.
