Hello there, welcome!

My name is Charles but everyone calls me Charlie. I am a postdoctoral researcher in the Computer Science department at Aalto University, working at the intersection of natural language processing and computing education. I am developping methods and frameworks for aligning language models with pedagogical objectives, with applications in automated programming feedback generation and evaluation, and simulated learners. I focus particularly on lightweight, open models that can be safely deployed in educational contexts.

My PhD dissertation laid the groundwork for this.
