Significant Variability in Terpene Content and Secondary Organic Aerosol Formation Potential from Ozonolysis of Consumer Product Categories Used Indoors Measuring the secondary organic aerosol (SOA) formation potential of common consumer chemical products is important for understanding the impacts of product use on ambient air quality. We performed co...

Still catching my breath after a wonderful #AAAR2025 meeting last week in Buffalo, NY. It is always to nice to reconnect with such a kind and welcoming community. I was proud to have 3 presentations from my group, including PhD students Sofie Schwink and Rileigh Robertson.

Investigating transport of particulate matter from cooking emissions in a multi-story house using low-cost sensor measurements and different modeling approaches This work investigates the transport of fine particulate matter (PM2.5) in a multi-story test house using cooking emissions as a point source. The tes…

So proud to share this new paper from my research group in collaboration with NIST scientists during the CASA Field Study! We look at particle transport in a house and compare 3 models: a box model, an empirical model, and CONTAM.

Thanks, Dustin! It's a fun campaign and it's bringing back lots of fond memories of CASA and HOMEChem.

Today, I received a termination for my National Science Foundation CAREER Grant, which employed a post-doc and many undergraduate research assistants.

🧪 Reports from inside NSF - staff were informed another huge set of grants were terminated today, that NSF will have at least a 50% total RIF, & no Acting Director has been appointed.

So, who is leading NSF?
#SciSky @science.org @scinews.bsky.social @aaas.org @aeraedresearch.bsky.social

Preliminary number of NSF grants to be terminated today is ~600, per sources. Including last week's cluster, this would put the total around 1,000.

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 have now heard from several reliable sources outside and inside NSF that the fears about research.gov are not well-founded.

I apologize for contributing to excessive concern.

But, better safe than sorry these days...

URGENT ACTION FOR NSF GRANTEES.

For current & recent (since 2020) awards, archive your award history this afternoon/tonight. Screenshot/download/print your work in research.gov & alert your partners.

Stand Up for NOAA Research – The Time to Act is Now The AMS is a global community committed to advancing weather, water, and climate science and service.

This administration plans to eliminate NOAA Research, which costs every American citizen less than a cup of coffee a year. Do you like knowing the weather forecast? Being warned of hurricanes, wildfires, tsunamis? It will all go away if the public does not act.

Particle Transport and Building Ventilation Limit Indoor Air Cleaner Performance during Wildfire Smoke Events Portable air cleaners (PACs) are often recommended to mitigate indoor particulate matter levels during wildfire smoke events. These devices can remove smoke particles by using mechanical filters or m...

A reminder that if the government can send migrants to a prison camp without any due process, it can send U.S. citizens there, too. I know because this happened to me and my family in 1942.

March is Women's History Month. Tough to be a woman right now and a scientist on top of it. But we carry on and we support one another!

NOAA firings hit the birthplace of weather and climate forecasting Dismissed researchers were improving severe weather predictions

The American Meteorological Society warned the firings will “cause irreparable harm and have far-reaching consequences for public safety, economic well-being, and the United States’s global leadership.”
