Hi, I’m Anna. I’m a graduate student in the Atmosphere and Ocean Dynamics and Transport Group of the Department of Earth and Planetary Sciences at Johns Hopkins University. I also run Baltimore Open Air, an urban monitoring network measuring air quality in Baltimore, Maryland.

I’m interested in climate dynamics and understanding the how and why of what goes on in our atmosphere. My thesis research looks at how the urban heat island effect–the tendency for cities to be hotter than rural areas––changes during heatwaves, using observations, low-cost sensors, and models from cities around the world. I’ve also been known to dabble in projects on regional hydrology, the climate impacts of aerosols, and North African precipitation.

I’m also an advocate for urbanism, sustainability, and open source software practices.
