I am committed to excellence in teaching. I am passionate about it, achieve immense satisfaction from it, and take great pride in my students' achievements. My main objective in teaching is to engage my students. I encourage student participation with group activities and classroom demonstrations with props and other manipulatives. I aim to provide experiences for my students that are enlightening, stimulating, and offer opportunities for student participation, at times including humor (and magic!) to further instill a comfortable learning atmosphere. I continually challenge and set high expectations for my students. To learn mathematics one must do mathematics, and to do it correctly and with serious effort and particular attention to detail. I emphasize to my students the importance of learning mathematics, particularly its usefulness and its many applications to life experiences.

My current research focus has mostly been in mathematics education, as part of a "community of practice" with colleagues in Mathematics and Statistics and Urban Education at UHD since 2010. Such participation, specifically in both the UHD Noyce Mathematics Teacher Scholarship Program and the UHD Teacher Quality Mathematics Leadership Project, have inspired and challenged me to become a better teacher (and for some courses, co-teacher) for my students, to think about teaching in new and exciting ways, and to apply these new teaching strategies and techniques in all of my courses, from freshman-level algebra to sophomore-level calculus to upper level operations research and decision mathematics courses, and also our teacher preparation courses for future elementary, middle, and high school teachers. As such, my teaching style has gradually progressed from initially a "teacher-centered" focus to more of a "learner-centered" focus

Academic Interest

My scholarly areas of expertise and research are mainly in graph theory and discrete mathematics, operations research, management science, mathematical programming, and mathematics education and curriculum development. My teaching interests, however, are quite varied and encompass a wide range of topics in both pure and applied mathematics in addition to those mentioned above, from introductory-level subjects such as algebra, precalculus, calculus, or finite mathematics, to more upper-level topics such as combinatorics, number theory, operations research, computational mathematics, or combinatorial optimization. I also enjoy teaching mathematics concepts courses for future elementary and middle school teachers.
