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.
