Diabetes Phenotypes Quantified via a Physiofunctional Model Fitted to Raw CGM Time Series Data

I've been reflecting on a peer-reviewed abstract I co-authored and presented at the 2022 DTS (Diabetes Technology Society) conference, entitled Diabetes Phenotypes Quantified via a Physiofunctional Model Fitted to Raw CGM Time Series Data. Here linked is the final author's manuscript copy of the published abstract.

This was some of the first quantitative modeling I had done at such a large scale--- tens of thousands of individuals represented in a multi-million row dataset, comprising many years'-worth of diabetes-focused health monitoring efforts.

I collaborated daily with colleagues who diligently applied themselves to curating well-labeled samples, ensuring a well-defined hypothesis space was not only possible but was guaranteed via sound statistical reasoning.

This experience really opened my eyes to a few key truths, namely the degree to which Big Data can capture actionable insights with remarkable quantitative certainty.

The possibility of such profound real-world impact has further motivated me to be meticulous in my work.

As founder of PFun Digital Health, I'm developing an evidence-based inference method that enables automated generation of personalized health tips (click to try the live PFun Health Tips web demo).

Persistence has been the only way forward; I'm currently still working on this solo, without any formal organizational affiliation. There are days I question if my intent is to experience pure sysiphean punishment. After reflection though, I can state with confidence that my trudging progress is borne of a desire to continue the momentum of that first impulse, to finally reach out and touch someone.

My journey troubleshooting a cheap usb video capture card (Linux)

I recently purchased an unbranded (cheap) USB video capture card on Ebay.

I started with the intended goal of recording & streaming using OBS Studio via my gaming/dev-desktop (running Manjaro Linux).

 This is the tale of my troubleshooting journey, how it's looking now, and also my new Twitch stream.

Spotlight: Demos Gallery

Wanted to draw your attention to the Demos Gallery, which I'll continue updating with new interactive demos as they come. Hope you learn something useful! Please leave a comment to ask questions or spark discussion. ✌️

PFun Glucose Demo

Interactive simulation of circadian-ultradian glucose dynamics (over a 24-hour period)

A quick prelude...

(EDITED: 2025-08-19)

Before you launch into these results... I'll give you some extra special ~~~insider information~~~πŸ‘€πŸ‘€...πŸ€«πŸ‘€

I have another demo that's almost ready to show off...

Likely I'll have some time to write a sufficient blog post in the near future.

For now, I'll leave you with a tasty hint...

An interactive biophysical simulation of glucose dynamics, estimated over a single 24-hour period.  The curves shown represent: Meal-likelihood [0.0, 1.0], Glucose [0.0, 2.0], Insulin. This is a simplified version of the full model to avoid too much computational overhead (we're really maxing out Desmos here).
