My neighborhood is getting absolutely wrecked by smoke tonight.. all the air purifiers in my house running on full blast

Life update: I made another really good baby. Enjoying maternity leave with this little peanut.

Join Hannah Horowitz and me in Chicago for ACS Fall 2026 (August 23 - 27) for a discussion of “Atmospheric Chemistry from Molecular to Global Scales!” Abstract submission is available here through March 30: callforabstracts.acs.org/acsfall2026/...

A fun fact about me is that I am measles non-immune. I have been vaccinated 3x (twice as a child on the regular schedule, and once after my first pregnancy when my titers came back negative for measles). They tested my titers again at the beginning of this pregnancy and still no measles immunity.

Cannot believe this little goober turns 3 in just a few short weeks! Loving my big kid but missing having a baby.. good thing we're getting another one this spring!

UPS keeps attempting to deliver us a package and, without knocking, simply leaving a slip and walking away. They want to charge us 8 dollars to hold it at the UPS location. I need to lie down for 12 years

Tell me you have a toddler without telling me you have a toddler

Another terrifying article about Stardust, with (what I think is) some new info: - they claim they'll finally release info on their secret particles starting in early 2026 - they plan a first atmospheric test in 2027 - they've been funding academic research (with one PI named)

Every word of this www.thecrimson.com/article/2025...

It is raining so much in LA and now I have to decide if I want to spend a Saturday cooped up at home with my toddler or if we both want to get a hideous virus at an indoor playground

Add this to my list of stuff to worry about: LA is about to get atmospheric river-ed. Just as a reminder, this is what happened last time we got a big storm. Please cross your fingers and toes for a flood free weekend in the barber lab!

the transition from programs/files/folders as the default mode of interacting with an OS to an app-based model where most things are stored on the cloud has already made things hard- students often have no idea that files are organized in directories, and that you can navigate that structure

Today my @nytimes.com colleagues and I are launching a new series called Lost Science. We interview US scientists who can no longer discover something new about our world, thanks to this year‘s cuts. Here is my first interview with a scientist who studied bees and fires. Gift link: nyti.ms/3IWXbiE

I am able to sponsor postdoctoral fellows through this program! www.chemistry.ucla.edu/bhaumik-priz...

Imagine thinking that having a baby that only needs 4 hours of sleep is a desirable trait lmao we live in hell

I have a student with a full draft, who now is ineligible. What a waste. Especially challenging for students in chemistry who don't settle into labs until at least half way through their first year.

A good read on an important chapter of Earth science history, and what is at risk of being lost under Trump.

Joseph S. Francisco named 2025 Pauling Medal Award winner The award will be presented Oct. 18 at Seattle University as part of a poster session and symposium. cen.acs.org/people/award... #chemsky

We took my 2 yo to his first baseball game today and my favorite part was when we told him it was over and the Dodgers won, and he thought for a second, then put up his hand and waved goodbye while yelling "bye bye Dodgers! Bye bye baseball guys!"

Hey, uh, what the FUCK

The vibes at UCLA today are not good.

God what a demoralizing time to be an early career scientist in the US

Breaking: NSF is suspending roughly 300 grants with UCLA, following a DOJ finding on Tuesday that the university violated Title VI by "creating a hostile educational environment for Jewish and Israeli students."

Nadia’s paper exploring technologies that can be used to minimize harmful byproducts of 222 nm germicidal light is now published! pubs.acs.org/doi/10.1021/...

Surreal to be back in Cambridge today!

An underrated part of being a lab scientist is how much confidence it gives you for small fixes around the house.

Here’s Spencer Ackerman with by far the best take I’ve read on the racist moral panic targeting Zohran Mamdami. zeteo.com/p/my-fellow-...

Amid all of the truly terrible federal funding news, I am extremely pleased to report my group has received our first multi-year NSF support!

"Women are PIs on 58% of the canceled grants, although they are PIs on only 34% of all active NSF grants. Similarly, Blacks are PIs on 17% of the terminated grants, although they make only 4% of the total pool. Hispanic PIs and those with disabilities were twice as likely to lose a grant."

Please support my students kickstarter to finish an educational wastewater video game we started building! I taught an interdisciplinary capstone class video game where programmers, artists, sound designers, and education students could work together! www.kickstarter.com/projects/que...

NSF grants partially supported me as a graduate student and completely supported me as a postdoc. NSF made the first external grant to my lab at UCLA (a small grant to support measurmenta of the impacts on ambient and indoor air quality from the Los Angeles wildfires). I am an NSF-made scientist.

My 2 year old made me a beautiful bracelet at school for mothers day, but upon giving it to me immediately decided that he wanted to wear it himself and became enraged whenever I asked to wear it. Really comports with my experience of parenting a toddler. Love that little goober.

Report from @science.org: • NSF staff told that its 37 divisions are being abolished. Programs within to be drastically reduced. • Layoffs expected, details via memo Friday 5/9. • Another round of grant terminations expected. (Already 1400 cancelled ~$1bn) www.science.org/content/arti...

On Friday I put a couch in my office and hung some art and now my productivity is through the roof and also I want to hang more stuff so give me your recommendations for cool places to buy lightly science themed art

Got an exclusive preview of the Auburn University Geo Explorer Lab, a 37 foot RV mobile learning lab under construction that will introduce students, teachers, and community partners to the breadth of geoscience approaches to science and social studies learning.

I just got the email, my funding request to #NSF was approved a while back, but NSF will not provide the funds. I feel awful for my students. I feel awful for my program manager. I feel awful for #science & #America

I just heard the disappointing news that a @nationalacademies.org study on far UV to reduce transmission of respiratory infections was canceled. www.nationalacademies.org/our-work/cli... /1

NSF director to resign amid grant terminations, job cuts, and controversy www.science.org/content/arti...

Time to throw up a bat signal for a specific skillset for @skypeascientist.bsky.social We have a classroom that is looking for a scientist who can do a session with them in ASL. Do we know any scientists who would be willing to do a Q&A with a deaf classroom in ASL?

Hi! #journorequest here: For HCN, I'm looking to speak with #federal scientists from the West who are preparing for #fieldwork this upcoming season. How has the federal chaos affect your planning? I'd be happy to offer anonymity. You can reach me at [email protected] or via Signal @shienkim.1721.

NSF GRFP Awards by the Year: 2021 - 2074 2022 - 2193 2023 - 2555 2024 - 2036 2025 - 1000 Again, these funding cuts will have drastic longterm effects on the scientific future of the US....... @jeremymberg.bsky.social @altnih4science.bsky.social

The Barber group is at ACS! catch me tomorrow afternoon at 2:45 in our "Showcasing Emerging Science in Atmospheric Chemistry" session giving a *surprise* talk on our work on RO2 chemistry. Then, catch up with us again for 3 group posters in the corresponding poster session Wednesday afternoon!

#ACSSpring2025 Very excited for our first set of talks tomorrow morning! We have invited talks by Franz Geiger, @atmosyz.bsky.social, Haofei Zhang, Kevin Wilson, Anthony Carrasquillo, and Marcelo Guzman. Come here about Atmospheric Multiphase Chemistry in the Marriott Grand Ballroom: Section 2!!

We have an excellent set of presentations lined up at ACS in San Diego next week. If you are at ACS and want to hear the newest research in atmospheric chemistry come join us in the Marriott Grand Ballroom!! @pubs.acs.org @vbarber.bsky.social

Listed: "Reconsideration of Particulate Matter National Ambient Air Quality Standards" Americans live an avg 1.5yrs longer because of these standards. In some regions, up to 5. From 1990-2020, AQ regs delivered $2T in savings, >30x enforcement costs. These are a DEAL. www.epa.gov/newsreleases...

Bringing my toddler to stand up for science was the best decision I have made this year. He got to sit on my shoulders and yell and hold a sign and we loved every minute of it.

Bringing my 2 year old to his first protest on Fri because that kid is going to love shouting and holding a sign and you gotta start em young

So should I be trying to get my 2 year old an early second dose of the MMR vaccine or?

NASEM, you have the opportunity to show leadership during these times and speak up for science and for Americans. I understand the political pressures but you're the creme de la creme of American excellence. What are we doing here.

Would you believe on top of everything else my labs flooded tonight? (We are fine, instruments are fine)
