Hello there!
Jędrzej Wydra
As a “double master” — not a Jedi Master (though that would be pretty awesome), but someone who holds two master’s degrees — I’ve combined my expertise in law and mathematics to delve into the world of forensic science. My research primarily focuses on evaluating evidence related to time of death estimation, developing tools that could greatly assist judges and forensic experts in their critical decision-making processes. In my professional life as a data scientist, I tackle a variety of projects, with a current emphasis on integrating AI into legal practice.
Why did I choose this path? Once I heard a lawyer say, ‘If I could do math, I would be too powerful’, and that was the moment when I decided to gain that power. When I’m not dissecting legal texts or crunching data, you can find me sipping fine Matcha, diving into psychology studies, or working on my calisthenics routine.

Who Should Regulate AI: Lawyers or AI Engineers
September 2025
Artificial intelligence is advancing at breakneck speed, but who should be responsible for regulating it? Lawyers? AI Engineers? Both? In this provocative and timely piece, I reflect on the legal, ethical, and historical dimensions of this ongoing debate, exploring what we risk when the wrong hands hold the pen.

Sun, Earth, and a Matter of Perspective
September 2025
Does the Sun really need to be at the center of the Solar System? In my latest Medium article, I dive into geometry, astronomy, and a bit of philosophical fun to show how the answer depends entirely on your point of view — literally.
It's a lighthearted yet insightful piece about how shifting the coordinate system can reshape the cosmos, without altering its actual dynamics.

New Publication in Journal of Forensic and Legal Medicine!
August 2025
Exciting update! My latest article, titled “Reliability of fingerprint experts in extracting and evaluating minutiae in individualization tests of fingerprint traces”, has just been published in Journal of Forensic and Legal Medicine. This study tackles a crucial issue in forensic science — how consistent fingerprint experts really are when identifying minutiae.
We analyzed many test results from Polish fingerprint experts and uncovered notable variability in the way evidence is interpreted. It's a contribution I’m genuinely proud of, as it adds to the growing body of research calling for stronger standards and quality control in forensic practice.
The full article is now available on the publisher’s website — feel free to take a look!
When Exams Fail (and It’s Not the Students)
July 2025
Some exams reveal more about their authors than about the students who take them. In this article, I used a bit of math — and the Central Limit Theorem — to explore what grade distributions really tell us. The story started with one particularly strange exam where two-thirds of the students failed. Was it really their fault? Or did the exam fail them?

Great News: Positive Review of the AI Act Commentary!
June 2025
Thrilled to share that the commentary on the AI Act, which I had the privilege to co-edit, has received an excellent review! It’s incredibly rewarding to see the effort of countless hours of research, writing, and editing recognized so positively.
The official release of the book is planned for October 2025. More information at publisher site.
Fresh Preprint Released!
June 2025
Excited to share my latest preprint: "Interval Estimation of Thermal Summation Parameters in Forensically Important Insects" is now available on Research Square! This is an important milestone, as it marks the final piece of a larger project on estimating time of death — a challenging yet deeply rewarding research journey.

Encryption, Algebra, and a Guest Lecture
May 2025
What started as a spontaneous “sure, I’ll help” turned into a full article exploring how encryption actually works — from ancient ciphers to elliptic curves. The piece was born from a guest lecture on data protection and turned into a crash course in cryptography, complete with modular arithmetic, shared secrets, and the kind of algebra you never thought you’d use again.
Major Milestone: Publication in Signal Processing!
March 2025
Thrilled to announce that my latest research on the independence of functional data has been officially published in Signal Processing! This was, without a doubt, one of the most challenging projects I’ve worked on — combining deep mathematical concepts with rigorous analysis.
Mathematics has always been close to my heart, and having this work featured in the best journal I’ve published in so far makes this achievement even more special. If you're interested in the details, you can check out the full article in Signal Processing!
Big News: Publication in Science & Justice!
December 2024
Exciting update! My work on reconstructing temperature conditions at crime scenes has now been officially published in Science & Justice! This was a challenging yet deeply rewarding project, and seeing it featured in such a respected journal is a huge milestone for me.
If you're curious about forensic temperature reconstruction and how it aids criminal investigations, you can check out the full article in Science & Justice!
New Preprint is Out!
November 2024
Excited to announce my latest preprint: "Distance of Mean Embedding for Testing Independence of Functional Data" is now available on SSRN! This project marks a step into a new field for me, making it a particularly rewarding accomplishment.
Dive into the preprint on SSRN!
Justice Meets Algorithms
October 2024
I’ve just published a new article on Medium: "Can an Algorithm Speak on Behalf of Justice?" It’s a thought-provoking dive into the intersection of AI and the legal system. While a departure from coding and data crunching, this piece explores how algorithms might shape the future of justice — or perhaps just spark a lot of questions.
New Preprint is Live!
September 2024
I’ve just shared something I’m really proud of — a preprint titled “Forensically useful mid-term and short-term temperature reconstruction for quasi-indoor death scenes” on ArXiv. This one was a tough project, but it’s a big success for me.
Check it out on ArXiv if you’re curious!
Red alert! No, wait... MEDIUM ALTER!
August 2024
I’ve just ventured into something a bit different — a light-hearted article about tea, now up on Medium. It’s a small departure from my usual academic work, but sometimes it’s refreshing to explore new brews. Feel free to take a sip of it here!
Second Website Ever Built!
