Curriculum Vitae 

Teaching Philosophy

Quality education is essential to maintaining and advancing the quality of life in the world and this is the reason one of my primary goals in life is to be a an effective educator. In my short time at Pacific, I have enjoyed teaching chemistry related topics to diverse audiences. Whether you are a toddler, high schooler, undergraduate, or graduate student, I find it a rewarding challenge to help students learn chemical principles. I view my role in the education process as a facilitator - I cannot make the student learn anything - I can only inspire, demonstrate, simplify, facilitate collaboration, offer alternative explanations, and provide real world examples. I am a strong proponent of experiential learning, so I do my best to provide research opportunities for both graduate and undergraduate students. I am here to expose students to tools they need to think critically and implement solutions to chemical problems.

Research Interests

My research is focused on determining the chemical and physical properties of aerosol particles. Understanding the detailed characteristics of these particles is essential to enable advances in our understanding of atmospheric pollution and climate change. Furthermore, aerosols have unique properties that have led to their use in diverse fields from medicine to engineering. Most aerosols that are common in nature are exceedingly small (less than 1/1000th the diameter of a human hair!!), and thus require advanced analytical techniques to probe their chemical composition and morphology.

We use single particle techniques to determine the chemical and physical properties of individual aerosol particles. We use single particle mass spectrometry - which is a real-time technique we use to obtain the size and chemical composition of particles as small as 100 nm. We also utilize state-of-the-art X-ray and electron microscopy at the Lawrence Berkeley National Laboratory and Pacific Northwest National Laboratory's Environmental Molecular Sciences Laboratory to gain coupled information on particle morphology and chemical composition.

Molecular information about organic aerosols is obtained using advanced mass spectrometric techniques available at the University of the Pacific's Mass Spectrometry Facility. Typically particles are collected onto a filter, extracted and analyzed. We are interested direct sampling techniques that avoid the complications that arise during extraction.
