Courses at MCLA:
Introduction To Biology
- Introductory course for majors, and part of the core curriculum.

Cell Biology - One of two senior level required biology courses, average class size: 10 students.

Microbiology - A requirement for Health Science concentrations, class focuses on prokaryotes (bacteria). Average class size: 6 students. 

Parasitology - An upper level elective, focusing on parasites. Average class size: 6 students.

Human Biology - A lower level component of the core curriculum. Average class size: 20 students.

Coordinator of the Pre-Professional Studies, Allied Health, Pre-Occupational Therapy, and Medical Technology programs.

College Community
I am an honorary member and Faculty Representative of the First Year Honor Society, Alpha Lambda Delta and serve as a committee member on the Institutional Review Board, All-College Committee, and Student Research/Creative Project Committee. I also serve as the Advisor for the Biology Club.

Research
I have two ongoing research projects. The first is Enology. Our lab employs a variety of methods in the identification of yeast speciation including morphological characteristics, fermentation studies, and molecular techniques (Polymerase Chain Reaction and Restriction Fragment Length Polymorphisms). The goals are to identify yeast naturally occurring at regional wineries, to determine if they vary from region to region, and to give the wineries information that can be utilized to enhance flavor and production.

The second involves the protozoan parasites Trichomonas vaginalis and Tritrichomonas foetus. These parasites cause trichomoniasis in human and cattle, respectively. Human trichomoniasis is the most prevalent nonviral sexually transmitted disease in the world. Our lab employs biochemical and molecular techniques to study the metabolic pathways of these organisms to gave knowledge which may be applied to chemotherapy.

Student researchers have presented their work at the MCLA Undergraduate Research Conference and at regional American Society of Microbiology conferences.
