Associate Professor

Teaching Interests

My teaching philosophy for the anatomical sciences is a hands-on approach. I believe short lectures followed by extensive laboratory dissection to be the best approach for education in anatomy. There is no replacement for the cadaver when it comes to medical education. It is not only that the cadaver provides the student with their “first patient,” it is also an unparalleled experience for hands-on learning and grants the ability to appreciate morphological variability. In addition, to didactic and laboratory experiences I also believe an approach that includes clinical vignettes to be very important to the early exposure of students to practicing medicine. I also include wherever possible clinical correlations for broad topics of study (e.g. “Spread of Infection to the Mediastinum” when covering mediastinum). My topics of focus include embryology, histology and gross anatomy of hard tissues and craniofacial development and anatomy.

Research Interests

My primary focus of study is in the area of craniofacial biology with a focus on birth defects and interventions for bone wound healing.
