This is pretty incredible work by @cncastillo.bsky.social!

Really exciting to see #medical #imaging continue to grow within #julialang -- especially the GPU acceleration via KomaMRI.jl (link: github.com/JuliaHealth/...)

Plus, the @makie.org plots look fantastic!

I am on the job market and wanted to advertise myself here! 🤠

Looking for full-time or contracting roles!

Historically, my work spans population dynamics, healthcare informatics, robust adaptive controls, software engineering, and community engagement. 🧪

Markian & I worked with Katy Sadowski to create small OMOP CDM patient databases.

We discussed a #workflow to generate 1 million patient DB that went from ~220GB to ~20GB -- ~90% data reduction!

Goal was to provide researchers more realistic & performant @duckdb.org DBs for health informatics. 📊🩺

My first time presenting on compositional public health outside a maths venue! Working on general slogans but we describe it as:

"Compositional public health empowers researchers to reclaim agency through abstraction in public health."

Time to run studies using AlgebraicJulia!

Great time @ohdsi.bsky.social Symposium!

Shared applied category theory ideas for #publichealth, won an award on data engineering using @duckdb.org, discussed multimodal health informatics & volleyball spiked folks with inflatable globes ( ✨OHDSI✨ things).

Proud of GSoC mentee, Indu, for finishing her fellowship with JuliaHealth on:

- Interface for multimodal & public health informatics
- Easing PLP with OMOP CDM DBs

Excited! Leads to robust prediction pipelines & stronger collaborations in #julialang!

BlueSky friends!

If you work with paradata ("data about processes"), where would you try submitting a paper about paradata & public health?

Have some notes that can be a paper; wondering what a good journal or conference would be.

TY!
