Bio:

Prior to taking my position as an Assistant Professor of Chemistry and Biochemistry at Siena, I held two postdoctoral research assistantships. The first was with Prof. Hase at Texas Tech University where I studied gas phase collisions between ions and surfaces. The second was with Prof. Kellman at the University of Oregon where I studied spectroscopic Hamiltonians fit to regions well above isomerization barriers.

My Favorite courses to teach are:

Chemistry 320: Quantum Mechanics and Spectroscopy
Chemistry 110/120: General Chemistry I and II

Professional Experience:

Assistant Professor Siena College 2012 - Now
Postdoctoral Research Assistant University of Oregon 2009 - 2012
Postdoctoral Research Assistant Texas Tech University 2008 - 2009

Why I chose Siena:

Siena has a solid mixture of teaching and undergraduate research. I strongly believe that undergraduate research greatly benefits education, and I try to incorporate at least brief glimpses of cutting-edge research into my courses. I thoroughly enjoy the close interactions that I have with students at Siena both in the classroom and in research.

My current research:

I am very interested in chemical dynamics. Specifically, I try to decipher the mechanism for high-energy reactions that take place between protonated peptide and organic self-assembled monolayer surfaces. My research group and I perform atomistic simulations that have highlighted the importance of proton mobility in both interfacial reactivity and statistical fragmentation events. For more information, visit my research webpage.

My teaching philosophy:

I encourage students to become active participants in the teaching process. I love when students ask questions in lecture and studio. Some of the most interesting and informative discussions start from simple questions.
