My Harvard Horizons video is now on YouTube! I worked hard on this with some talented animators, really excited to share it with ya'll :)
This is a short, public talk of my research: exploring connections between galaxies and cosmology with @desisurvey. https://www.youtube.com/watch?v=BIB0F_oNxdM

Today the DESI Survey announces measurements of the expanding universe - the most precise of their kind! I had to make a cake.

I'm so excited to finally share our first main science results :)

@AnnaAnthro no video, but here's a pic of making the big dish. I baked it on a wok

Yay, I can share this now!!
After seeing my paper doodles, an editor reached out to me about creating something for Physics Today. Presenting: a cartoon summary of one of the most impactful papers in modern cosmology!

Today I have a new paper up on the arXiv and I've doodled another summary! Here are the first three pages. I take great joy in reducing complex, majestic galaxies into ovals.

The cosmic web leaves a mark on visible matter through subtle correlations involving galaxy shapes. How do we quantify these "Intrinsic Alignments"?
For the long answer, see “The IA Guide”, now on arXiv! For the short answer, keep reading.

Individual galaxies are beautifully unique and complex objects. But as an observational cosmologist, I see them as many flat ovals on the sky. Each galaxy can be described by a number, ellipticity, which contains information about how round the galaxy is and its orientation.

We explore how these shapes correlate with other properties by measuring them relative to some direction, such as another galaxy or dense regions of the cosmic web. My cat kindly agreed to demonstrate various ellipticities relative to the most important direction, her food.

The best type of Black Forest cake is a Black Lyman-alpha Forest cake

Here's some pre-sketches I've made when planning out bakes! Never felt comfortable enough to post these on the other place.

A sketch and corresponding bake or a pie that looks like a pie chart of the contents of the universe (matter, dark matter, dark energy)
Sketch and corresponding bake of a round cookie with a galaxy-like frosting base. Piped in in white icing is the outline of the Chandra Observatory
A sketch and bake of a black cake. Painted on it is the milky way with streams coming off which turn into fall leaves and circle the cake.

Our universe is rippling with waves caused by massive events, such as merging black holes. Up until yesterday, we didn’t have any evidence of long-wavelength, ‘background’ . But now @nanograv has announced a detection! A network of pulsars measured very carefully has revealed a faint hum in spacetime itself. Though luckily you don’t need pulsars to detect these cookies, a mouth works just fine 😉

My gingerbread creations from the past two years. Any ideas for what I should try this year?

Hey there. I am a PhD student exploring how galaxies are connected with the large-scale structure of the universe and what that reveals about dark energy. I enjoy figuring out how to condense information- whether it be for galaxy statics, outreach, or decorating science bakes
