Hello and welcome to my personal website!

I am currently working as a Machine Learning Engineer at Belgian scale-up, LynxCare, working on models for clinical natural language processing. Before, I was a research scientist at Nuance Automotive (now Cerence) and a postdoctoral researcher of IDLab's Text-to-Knowledge Group. My research focused on techniques to train and deploy neural network based natural language processing in low-resource settings. I have worked on projects and done research involving sequence-to-sequence models, clinical natural language processing, keyphrase extraction and knowledge base population.

Feel free to reach out via mail, or connect on social media, if you want to get in touch.

Cheers,
Lucas
