Teaching Philosophy:

In my view, one of the greatest misconception students have about learning is that they are only responsible for studying, or they should only explore, the material given by the instructor on a given topic in the classroom. I strongly advocate students to explore beyond the textbook and have an appreciation for other resources. I do not believe that lecturing solely to a classroom can instill knowledge, or more importantly curiosity. Student participation is equally critical. Whenever possible, I encourage students to work in small groups, where they can not only develop leadership skills but also develop how to work effectively in a team and learn from each other. In addition, I believe in problem solving on the blackboard.  I know that survival in our society requires more than the knowledge we acquire from textbooks. Valuable skills such as team participation, leadership, critical thinking, problem solving and possessing an active curiosity of our world, are not only essential for personal survival and growth but also for the improvement of our society.

Research Interests:

1) I am interested in the fabrication of novel nanomaterials hybrids involving carbon nanotubes and the incorporation of these hybrids into practical applications. 

2) I am also interested in improving undergraduate students' understanding and appreciation for the fundamental principles of chemistry. I am specifically interested in student-centered classrooms, and active and cooperative learning to teach chemistry to community college students.
