- Pedagogical : Currently I am dedicated to develop active learning environments in classroom and teaching labs to enhance critical thinking and independent performance in science students.
- Advising and Curriculum evaluation: I actively participate in curriculum development, content examination and student advising at Department, College and University levels
- Research: Biophysical characterization of membrane transport mechanisms: Functional analysis of membrane ion channels constituted by connexins and pannexins proteins
