News
2/13/21 - During my postdoc I've had the wonderful opportunity to collaborate with researchers at the National Center for Atmospheric Research in Boulder, CO, combining global modeling with field data to understand the budgets of organic molecules in the remote atmosphere. It's been a long time coming, but our investigation of background atmospheric methanol concentrations is finally published!
2/5/21 - Ozone pollution is typically worst in the summer, but in recent work led by Ke Li and just published in PNAS, we find that wintertime ozone pollution is increasing in Beijing, China, fueled by high radical production from formaldehyde photolysis and decreased radical titration as nitrogen oxide emissions have decreased.
12/10/20 - The isoprene saga continues! Today, we published a paper led by Krystal Vasquez in PNAS describing the rapid hydrolysis of isoprene-derived nitrates in cloud and aerosol droplets, and the importance of this chemistry for atmospheric reactive nitrogen budgets.
11/18/20 - Today I'm (virtually) presenting at the Atmospheric Chemical Mechanisms conference about our recent work at Harvard comparing and optimizing a simplified oxidation mechanism for benzene, toluene, and xylenes in the gas phase. Next step: getting it published and putting it in GEOS-Chem!
10/1/20 - I've gone back to my roots as an experimental chemist and starting working in Prof. Tran Nguyen's Lab at UC Davis as a Visiting Research Associate! Excited to run some environmental chamber studies and investigate more details of the atmospheric chemistry of pinene and isoprene.
9/12/20 - I'm very excited about our new publication in Nature, led by Kelley Wells at the University of Minnesota, showing the first global atmospheric isoprene measurements made from space! You can find the paper here or read a summary here.
8/7/20 - This week I make my first foray into the virtual presentation format -- just uploaded my invited talk for the American Chemical Society's Fall Meeting on the roles of organic hydroperoxides and formaldehyde in atmospheric sulfur chemistry!
7/23/20 - Check out our new paper led by Siyuan Wang on the global budget of atmospheric acetone, the importance of air-sea acetone exchange, and the contribution of acetone to atmospheric radical budgets, all constrained with a wealth of observational data from the ATom Campaign.
6/3/20 - Results from our Monterey-based 2018 field campaign, the Marine Aerosol Cloud and Wildfire Study, are now published!
3/30/20 - Gas-phase mixing ratios of formic and acetic acids are routinely underestimated in global models. New work based on observations from our 2014 laboratory studies at Caltech shows that isoprene could be the culprit.
1/6/20 - Happy new year! Catch me at the American Meteorological Society's annual meeting in Boston, MA next week, where I'll be presenting my first invited conference talk (!) on model budgets of tropospheric ozone.
10/11/19 - I'm traveling to Portland, OR to present my work on the implementation of a new isoprene oxidation mechanism and its effects on organic, sulfate, and nitrate aerosol at the American Association for Aerosol Research annual conference.
9/19/19 - It's been a busy month, with two new papers published! The first is on the global effects of isoprene oxidation, and the second is about how we construct "budgets" of tropospheric ozone.
8/24/19 - Heading to Gothenburg, Sweden to present my work on simulating isoprene-derived secondary organic aerosol in GEOS-Chem at my first European Aerosol Conference!
7/15/19 - Kicking off an exciting week of science talks and career discussions with my fellow NOAA Climate & Global Change postdocs in beautiful Steamboat Springs, CO.
6/3/19 - Some results from chamber experiments I helped with at Caltech have just been published in Atmospheric Chemistry and Physics! This study, led by Becky Schwantes (now at NCAR), investigates the chemical pathways of aerosol formation from isoprene under high-NO conditions.
5/21/19 - I'm off to MIT today to give a talk on the influence of isoprene oxidation on sulfate, nitrate, and organic aerosol chemistry, and to visit the labs of Profs. Jesse Kroll and Colette Heald and chat about how we can benefit from added complexity in atmospheric chemical mechanisms.
5/6/19 - We're ready to kick off the ninth biennial International GEOS-Chem Conference! It'll be my third time at the conference, but my first as a member of the host group here at Harvard. I'll be giving a quick talk in one of the first sessions about my work on defining tropospheric ozone budgets in chemical transport models.
3/18/19 - About to give a talk here at NCAR on some recent work investigating tropospheric ozone budgets in global models. Hopefully the fact that I spent my weekend hiking instead of reviewing slides won't come back to bite me...
3/11/19 - I'm visiting the National Center for Atmospheric Research in Boulder, CO, to work with colleagues here on constraining the budgets of small oxidized organic compounds in the remote troposphere. Should be a fascinating two-week stay!
1/15/19 - One of my fellow NOAA C&GC postdocs was quoted today in the New York Times describing the effects of the government shutdown on our research funding and salaries. While I count myself lucky to be a part of this fellowship, it leaves us at the mercy of the government, which until recently I'd always considered a source of stability.
1/10/19 - Another paper published - this one with colleagues at the University of Copenhagen detailing the importance of unimolecular hydrogen shift reactions in the atmosphere! I think the coolest result from this work is that these reactions can be stereoselective, resulting in chiral enhancement in the atmosphere.
1/4/19 - Just arrived in sunny Phoenix, Arizona, where I'll be presenting some work on tropospheric ozone budgets at the American Meteorological Society's annual conference.

9/19/18 - I'm in the Tokyo Narita airport right now, en route to the International Global Atmospheric Chemistry Project's Science Conference in Takamatsu, Japan! I'll also be attending their early career short course to meet fellow atmospheric chemists from around the world.
9/1/18 - Off to St. Louis to see old friends and new research at the International Aerosol Conference! I'll be presenting my work on simulating SOA formation from isoprene in both box models & global models.
