Pieter Brugel the Elder, “The Tower of Babel”

Jacob Levernier, PhD

I make tools that help researchers find and work with data. I work across computer science, applied statistics, privacy and data ethics, and research design – five pillars around which I set a ten-year goal while early in my career to develop both depth and breadth of knowledge.

I most recently briefly helped lead the data and privacy initiatives for The Coleridge Initiative, a nonprofit startup that helps state and federal government agencies to safely use and protect sensitive public datasets at increasingly large scale, including roadmapping privacy and confidentiality work in statistical disclosure limitation for research exports.

Prior to that work, I was a senior software developer for the Applications Research Team in the Department of Biomedical and Health Informatics at the Children’s Hospital of Philadelphia, one of the top two pediatric research hospitals in the United States. My work focused on the Arcus Initiative, a platform that links clinical and research data to facilitate new and computationally-intensive research in pediatric medicine.

This Website

This website is titled Ad Unum Datum – In loose Latin, “Down to a single piece of data.”


I think that it is important to note that people’s reasoning, feeling, and opining change over time. Simultaneously, people’s vocabularies, their ability to describe and express their thoughts and feelings, develop over time. These facts are obvious, but are not always acknowledged in public discourse. Even personality, while largely stable, can change over time.

Thus, please keep in mind that almost everything that I express on this website is date-stamped; my words may not be the same, or even similar, to those that I would use to discuss a topic today.

On a similar note, AD·VNVM·DATVM is my personal website. I am not speaking for my employer or collaborators when I write here.

Short bits of code that do not have a license attached to them (e.g., snippets of CSS) are for you to use without feeling like you need to give credit (although it’s always nice): See the CC0 license. More substantive bits of code may have alternative (non-CC0) license notes attached to them, usually in their headers.

I’ve used this much text to describe license terms because I am a proponent of best practices for data and code management, and because I worry that leaving legally-relevant expectations ambiguous can lead to one or both parties in an interaction (here, the author and the user) feeling cheated. When someone authors or otherwise creates code, icons, or other types of content, and says it’s “free,” it’s often unclear what “free” means (Does “free” mean that I can use it, but need to provide a link back to the author’s website? Does it mean that I can use it as long as I’m not profiting off of its use?). It’s even more problematic when an author states that something is “free to use,” but has an “All Rights Reserved” notice at the bottom of the page (those two statements are potentially at odds with one another). Thus, in contrast to some who purposely leave their work unlicensed, I prefer to make all copyright and license terms as explicit as possible.
