Hello! | ¡Hola! | Hallo! | !مرحبا – Welcome to the cedar ledge! 👋

 zelko

My name is Jacob Scott Zelko! I am currently a Software Engineer at PlantingSpace and Research Affiliate at University of Saskatchewan's Computational Epidemiology and Public Health Informatics Lab (CEPHIL) Additionally, I am the leader of the open source and open science community, JuliaHealth.

My interests lie at the intersection of population health dynamics, applied category theory, knowledge representation, and open source. In particular, I am interested in how we can apply relational thinking approaches from pure mathematics to establish meaningful relationships between non-traditional health data sources to gain greater insights into population health. I have been actively involved within the OHDSI Community, Category Theory Zulip , and Julia Programming Language Slack.

In the past, I worked for a couple years at Georgia Tech Research Institute in the excellent HEAT Division as a Health Data Analytics and Informatics Researcher headed by Dr. Jon Duke and as a Research Engineer for the Centers for Disease Control. While in my undergrad, I also worked at Emory University's Department of Biomedical Informatics as a Data Information Specialist. I graduated from Northeastern University with an MS in Applied Mathematics, Georgia Institute of Technology with a BS in Biomedical Engineering [also completed coursework in biomedical informatics and medical anthropology], and an AS in Engineering Science at Corning Community College.

How to Navigate the cedar ledge? 💻

This website not only consists of blog posts, but is also my knowledge base. The main sections are broken up as follows:

How To Contact Me?

The best way to contact me is via my email which is jacobszelko@gmail.com. I welcome inquiry around my notes or blog posts, possible collaborations based on my projects or ideas, or consultancy requests.

Hobbies! 🎸

These days, I greatly enjoy working out regularly – weights, running, and free-body! I love reading and have been on a bit of a literature kick reading the works of Dostoyevsky, Faulkner, and other Southern Gothic literature – these certainly take some time to read! Finally, my more eclectic and smaller hobbies include blogging, electric and acoustic guitar, violin, traveling, and hanging out with friends over a cuppa tea.
