Hi! I'm Luke.

I focus on making an impact by using artificial intelligence in education.

I began my career by building supply chain systems at Amazon. I was entranced by this new website for sharing photos and news with friends - and soon joined the early effort to build out Facebook. I built early versions of Login With Facebook, and in particular helped people control their data with privacy controls. We worked on developing standard protocols for login, which resulted in OAuth 2.0.

After Facebook, I co-founded eSpark with David Vinca. The iPad had just come out, and we helped many students to learn with games and videos at their level.

While I was there, the machine learning research began making huge strides forward. In 2013, Word2Vec enabled efficient embeddings of tokens beyond naive strings; those advances led to the development of the Transformer architecture which later enabled Large Language Models. My team was excited about this. In 2017, we worked on developing an early writing assistant using machine learning. However, the technology too immature at the time to be really effective.

I knew that there was still huge promise in using machine learning for good. I looked for companies that were utilizing machine learning at scale - and I joined Tempus to help develop AI algorithms. While there, I led several ground breaking diagnostics across cancer, cardiology and neurology.

I took my kids out of school to home school and turn my attention to the next emerging area: Large Language Models. I’m a robotics coach with First Lego League, and I sit on the board at the Pediatric Epilepsy Surgery Alliance.
