Dien got her major in atmospheric sciences and is interested in studying the sources and sinks of carbon- and AQ- related fluxes at the local scale via atmospheric transport models and remote sensing techniques. She enjoys hiking and playing racquetball in her spare time.

Graduate Students

Haroula Baliaka

Department of Environmental Science and Engineering
Dipl. Ing., Chemical Engineering, University of Patras, Greece 2020
:

Haroula is a first-year graduate student. She is currently working on two projects; one with Paul Wennberg and one with John Seinfeld. In her free time, Haroula jokes that she is living the American dream.

Reina Buenconsejo

Department of Chemistry
B.A., Chemistry, Pomona College, 2015
:
Co-advisor: John Seinfeld

Reina is an experimental atmospheric chemist who researches volatile chemical products (VCPs). Her research focuses on elucidating the oxidative chemical mechanism of SOA formation from VCPs as well as quantifying their SOA yields. Reina enjoys mentoring other students in the lab and serving on CCE’s DEI committee. In her free time, you can find Reina doing arts and crafts, running, and playing with her kitten, Athena.

Sara Murphy

Department of Environmental Science and Engineering
B.A., Chemistry, Pomona College, 2018
M.S., Environmental Science and Engineering, California Institute of Technology, 2021
:

Sara studies the kinetics of bimolecular peroxy radical reactions. She is especially interested in developing methods for measuring the rates of these reactions, determining their mechanisms, and understanding how these reactions affect the real atmosphere. She is also passionate about teaching, mentoring, and outreach. In her free time, she enjoys playing bluegrass fiddle, hiking, and taking her cat Remus on walks.

Harrison Parker

Department of Environmental Science and Engineering
B.S., Environmental Engineering, University of California, San Diego, 2014
M.S., Environmental Science and Engineering, California Institute of Technology, 2020
:

Harrison (he/him) is interested in the overlap between remote sensing, greenhouse gases, and atmospheric chemistry. He is specifically  interested in how these three topics interact in the South Coast Air Basin during the large emission changes since 2010. After taking E110: Principles of University Teaching and Learning in STEM, he became interested in pedagogy and served as the Caltech Project for Effective Teaching graduate co-director. Outside of work, he enjoys writing and playing tabletop role playing games.

Ariana Tribby

Department of Chemistry
B.A., Chemistry, Pomona College, 2017
:

Ariana’s research focuses on improving the diagnosis of methane emissions from energy production using alkane signatures. She uses a combination of atmospheric chemical transport models and statistical modeling to estimate anthropogenic emissions on a regional and global scale. Outside of research, Ariana served as a live-in Resident Associate for undergraduates at Caltech for four years. She also enjoys hiking, cooking plant-based recipes, thrifting, and playing with her dog, Benji.
