About me

Hi everyone, I am Christina, currently based in Miami and this is my project collection website! Here, you’ll find a colourful mix of projects involving mechanistic interpretability, modular networks, layered directed acyclic graphs, and physics-informed neural networks, applied to both ophthalmology and climatology. P.S. if you like graphs, check out nodes-and-edges by Mateo and me!

Follow my research progress on bluesky or my semi-retired Twitter I also have Linkedin as well as an old-school pdf CV and I am happy to receive post via pigeon, but email may be faster .

Passion

Retinal disease understanding: To actually understand the data I have been working with in my deep learning projects over the past few years, I decided to pursue a master’s in Vision Science at the University of Miami. While growing my knowledge in ophthalmology, I continue working on DecentNet, a disentangled network approach that helps clarify how disease features interact in models.

Winter colony loss: The disentangled network approach will also be a key component of my upcoming PhD, where I’ll focus on bee health and the factors contributing to winter colony loss, using remote sensing data.

Cherry blossom: Another project using satellite data that I’m currently working on with the senv team involves applying physics-informed neural networks and incorporating climate data, such as La Niña and El Niño phenomena, to predict cherry blossom peak bloom days.

Space missions: My passion for space mission design is for the time being on hold, but everything I learned about planetary science and imaging devices at Conex Research and the ESA Alpbach summer school accompanies me in my remote sensing projects!

Projects

Semi-supervised vessel segmentation (Fetoscopy)

I was working on a semi-supervised vessel segmentation project at WEISS/University College London in the summer of 2021.

Survived day 5 of way too many smart people in my little hometown of Vienna ❤️ Learned a lot about graphs and mechanistic interpretability - it's fascinating what people around the world are working on!! #ICML2024 pic.twitter.com/wh1KU2tkoc
