Current Research

I am an atmospheric chemistry graduate student in the Jimenez Group, developing new measurement techniques to study secondary organic aerosol formation pathways. Particularly, I focus on the use of chemical ionization mass spectrometry and ion mobility mass spectrometry. 

Currently, I am conducting experiments in our smog chambers to examine gas-particle partitioning theory. Gases that are emitted into the atmosphere or formed from other gases as a result of photochemical reactions can condense onto preexisting aerosol particles, growing them and changing their chemical properties. Exactly how important this process is in the atmosphere is still controversial, however.

One of the new CU environmental "smog" chambers used to simulate atmospheric chemistry reactions. I study the physical processes underlying these chambers and use them to explore new pathways of forming atmospheric particles.
