Teaching Philosophy:

Throughout my undergraduate, doctorate, and postdoctoral training, I have been fortunate to have professors that were enthusiastic and dedicated to teaching. I have gained insight into successful techniques and practices that motivate students in organic chemistry and NMR spectroscopy. These include increased availability of the professors and contact with the students, being actively involved in thinking and reading about new chemistry and performing laboratory research with students, assigning homework problems that allow students to more easily learn chemistry through practice, encouraging board work by students when solving problems and having them describe their thought process as they think through the assignment, and being motivating and encouraging while teaching chemistry – making it easier to understand for all students. In particular, I am interested in implementing student-led workshops in organic chemistry classes where a weekly problem set is distributed and solved within small groups. This informal setting will lead to increased learning and open discussion among the students and is something that I aspire to in an effort to make organic chemistry a less daunting subject. I also would like to expose the students to the different types of chemistry that are currently being studied in universities and industry such as the synthesis of natural products and medicinal applications. This would involve assigning homework problems that address useful applications in organic chemistry, teaching students how to effectively search the current literature, directing students to appropriate websites, and bringing in seminar speakers who work in the pharmaceutical industry. I am also excited to emphasize analytical techniques used in assigning structure and stereochemistry along with my instruction in organic chemistry. The students would be exposed directly to the instruments in the laboratory sections including the set-up and data analysis. I believe that a more thorough understanding of organic chemistry and the subsequent analytical techniques used to study molecules both in and beyond the classroom setting will help students to better grasp what a career in chemistry would entail and help to increase the number of interested students in chemistry as a future profession.
