About

I am a Member of Technical Staff at Google DeepMind and work on optimizing the developer experience for our open Gemma models and the flagship Gemini models. As a psychologist turned AI professional I’m especially keen on making sure that models are being made in a way that puts the users first. I like to frequently switch between technical work, creating content, and being a psychologist whenever I can ;)

As a psychologist turned AI professional, I enjoy making AI accessible. I write illustrated explanations in Exploring Language Models and write books, including Hands-On Large Language Models and An Illustrated Guide to AI Agents.

I also build open-source software. BERTopic, KeyBERT, and PolyFuzz grew out of my work with text, from discovering topics in documents to extracting keywords and matching strings, and have collectively been downloaded over 30 million times. It is one of the biggest learning opportunities I’ve ever encountered. You can find the research behind this work on Google Scholar.

Teaching has taken me to courses and talks, including courses with DeepLearning.AI on Transformers and Analytics Vidhya on Mamba and state space models.

I’m also part of the RAG Pack, alongside people I consider my heroes: Jay Alammar, Chris McCormick, Josh Starmer, and Luis Serrano. Together, we create practical AI courses, free masterclasses, and training for engineers and technical teams, bringing our different approaches to explaining AI into one shared classroom.

Away from AI, my family is everything to me (and my daughter loves flamingos so I tend to throw a bunch of them in my content).
