Research and Professional Interests

The first area of research is identifying the role of neurokinin-B in the retrochiasmatic area of the hypothalamus in mediating estradiol negative feedback, and the interaction of neurokinin-B responsive neurons with A14/A15 dopaminergic cell groups in the same region. The second area of research is identifying the pathway and mechanisms through which estrogen-receptor-alpha-containing neurons in the arcuate nucleus of the hypothalamus are involved in seasonal inhibition of GnRH and LH secretion in ewes.

Courses Taught

I am currently fortunate to be able to pursue my long time passion for teaching and am currently teaching in human gross anatomy courses for medical, dental, dental hygiene and nursing students. Further, I am developing a new research program focused on improving educational approaches in the teaching of human anatomy. In particular, my interest is in introducing innovative curricula for the teaching of undergraduate anatomy courses by integrating clinical concepts into these courses. This research program is still in its infancy, so I hope to have more updates in the future.
