Welcome!

My name is Alex Hadjinicolaou and this is my corner of the internet.

As a neuroscientist, my current job is to work out how the brain encodes communicative intentions – the will to speak, for example. Since human thought is fluid and intentions can change at any time, my approach is to model intent as a hidden process whose dynamics can be inferred from spoken words. If we can capture intentions, then we can build more responsive brain-computer interfaces and improve the lives of those who depend on these devices.

When my fingers are not speaking MATLAB, I think about information security. We live in a world where massive data breaches happen all the time, but businesses have only recently begun to take our data privacy seriously. As a developer, I’m interested in learning more about secure software design, how to code defensively, and how to manage trust in applications.
