Harrison Pim

I'm a data scientist / machine learning engineer with a background in computational / quantum physics. I write loads of python and typescript, and a little bit of everything else.

I like working on hard R&D problems involving computer vision, natural language processing, graph theory, representation learning, recommendation systems, and information retrieval.
I love turning those research projects into services which help people in the real world.

Other Stuff

Teaching and mentoring

I try to share what I've learned through blog posts, reusable code, and/or talks at conferences and universities.
I've advised, mentored, and supervised first-time conference speakers, artists, researchers in industry and academia, grant funding applicants, and students all the way from GCSE to PhD.

Responsible machine learning

I care a lot about the ethical implications of my work. I'm a member of Mozilla's Building Trustworthy AI working group and the Museums + AI Network.

Software development

I've built a lot of open source tools, sites, and services outside of work to sharpen my own development skills and experiment with new technologies.

Cycling and outdoor swimming

I like swimming outdoors, especially through the winter. I've been cycling in London for eight years and I've only been hit by four cabs.
