Hello everyone! Let's connect!

I use genome editing to study sex differences in liver lipid #metabolism, intestinal lipid handling, and cardiometabolic disease.

In the nonscience world, you can find me reading, baking treats, and drinking coffee.

I do not recommend two back to back grant deadlines and endpoint for an entire atherosclerosis study all in the same month. Fingers crossed on all levels!

There’s a lot of tough things happening right now, but can we just take a second to highlight the pure joy that comes with cool data or a good science discussion?

Taking that small win home with me today.

I was hopping on here to make my own thread to this degree, but the first post on my feed was this excellent one! Have a read. It’s excellent!
Why is the NIH investing $$ to study "transgender" mice🐭? 🤔 Let me explain 👇 🧵

TL;DR This has everything to do with your health and nothing to do with making people #transgender.

We set aside 20min in class for a Q&A on funding a lab, federal funding, IDCs, and ongoing policy shifts. Was definitely not enough time. Such great and insightful questions

Probably could have taken the whole class

Anyway. 10/10 would recommend

Some good news: @hannahhrncir.bsky.social ‘s primary PhD paper is finally online! This study lays the groundwork for a lot of technical and conceptual things the lab is currently working on, including light sheet microscopy for imaging entire biliary trees in mouse liver: rdcu.be/d90Br 1/4
Sox9 inhibits Activin A to promote biliary maturation and branching morphogenesis
Nature Communications - The bile ducts of the liver form a network of large ducts and small ductules, though how they are patterned remains unclear. Hrncir et al. show that Sox9 is required for the...

Hi friends - we’re still safe at home from the fires here in Los Angeles as of Thursday morning. I hope the rest of you are safe as well!

The non-science thing I learned this year was espresso. This is now my favorite way to make coffee, but came with a huge learning curve. Latte art is difficult but makes me look forward to my latte. Espresso tonics with some citrus juice are also lovely.

Update - funded 😍
I’ve written a few small grants, but tonight is the first time I’ve finished one independently. I can actually look at it and think, “Yeah, I did that!”

Even if I’m not 100% happy with it, it is progress!

I think because of science, I tend to enjoy hobbies that are very protocol-driven. I also really love espresso and espresso drinks. Here’s my first shaken espresso on my new setup - I find iced drinks more forgiving if I don’t have the grind quite right!

Hi friends! It's time to start building my network here!

I'm a postdoctoral scholar at UCLA. I study lipids and atherosclerosis using AAV and genome editing in the liver.

I love chatting science and sometimes share what I'm up to - I'd love to connect!
