wouter bulten

I am Wouter Bulten. Currently, I am the Chief Operating & Product officer of Aiosyn, an AI startup focused on computational pathology. At Aiosyn, my goal is to bring innovation and AI research to clinical practice.

I hold a PhD on computational pathology with a focus on using artificial intelligence for clinical diagnostics. I performed my PhD research at the Computational pathology group of the Department of Pathology and the Diagnostic Image Analysis Group of the Radboud University Medical Center. As part of my PhD, I organized the international PANDA Challenge, in collaboration with Google Health and the Karolinska Institute.

Summer 2015, I graduated Cum laude in Artificial Intelligence at the Radboud University and received my Master of Science (MSc.) degree. Between 2011 and 2017 I worked as a Software Developer and Data Scientist at 123test. Next to this, I have been working as a freelance software developer for small to large sized companies since 2009.

This website is a portfolio of things I work on, both professionally and as a hobby (e.g., home automation). Not all content is 100% tech-focussed; I like to cook a wide range of dishes, some of which you can read more about on my food blog.
