I consider education to be the most important aspect of life because if we never learn then we may never grow. While research projects are important for intellectual growth one must first have a foundation constructed from a sturdy formal education which comes in the form of lecture and laboratory exercises. For this reason it is important that the coursework to educate students also expands in terms of content, along with the minds that use it.
I find that my pedagogy is not completely focused on the memorization of material but rather to produce students who are independent learners. My mother was an elementary school teacher who taught many students basic reading and math skills to prepare them for a life of learning. I often look at my teaching-style in a similar manner, I teach to foster life-time learning and real world problem solving skills while still focusing on the material, just as my mother has done for her students.
I do my best to promote long term goal planning of students, primarily career goals. I provide my input for career-oriented topics such as proof-reading resumes/cover letters, encouraging/providing students with information on summer internships, and providing my own insight of graduate school.
The subject matter of chemistry is often perceived as difficult which can be intimidating to most students. I feel it is the job of the instructor to alleviate some of this occlusion by guiding students through advanced chemical concepts while still providing enough freedom to encourage problem solving skills.
I use density functional theory (DFT) to study the interaction between discrete molecules with metal surfaces. Often the molecule is referred to as an adsorbate while the surface is sometimes called the substrate. These calculations required a supercomputer to run and take a large amount of time to complete but divulge important information about chemistry!
My research focuses on the following three areas.
- Fundamental studies of how adsorbates interact with substrates. It is surprising to note how little we know about the interaction of gas phase molecules with metal surfaces.
- The formation of extended networks of adsorbate molecules that adhered to metal surfaces to form ferroelectrics. The end goal of these studies is to find inexpensive ferroelectrics, which have great potential to revolutionize current electronics.
- The involvement of surface-adsorbate interactions in heterogeneous catalysis. This is has applications for fossil fuel consumption, organic synthesis, and pharmaceutical drugs.
I currently work with several collaborators that are located all around the world! They are:
Dr. Eva Zurek, SUNY, University at Buffalo, Buffalo, NY
- Dr. Axel Enders, Universität Bayreuth, Bavaria, Germany
- Dr. Charles Sykes, Tufts University, Medford, MA
- Dr. Jason Bennett, Penn State Erie, the Behrend College, Erie, PA
- Dr. Dianna Aga, SUNY, University at Buffalo, Buffalo, NY
If you are interested in becoming a collaborator and need some theoretical calculations do not hesitate to email me.
I am always happy and excited to get students involved with science! I try to engage students at the elementary and high school level via classroom visits. I often do chemistry demonstration shows or S.T.E.A.M. activities on my visits. Please contact me if you have interest in me coming to your classroom.
