I currently lead the Engineering, Data and IT orgs as CTO at MJH Life Sciences. MJH is the largest privately held health care media business in North America, reaching roughly 7 million health care professionals every month. My teams work on personalization, identity, predictive models and recommender systems at scale. It's great! Come work with us!

Prior to MJH, I led Machine Learning Engineering (MLE) teams at Audible in the city of Newark, where we launched LLM search, scaled our recommendation infrastructure with extremely-low latency operations over embeddings, and built the future of book listening (on public domain titles only, for now).

I've also had the pleasure of leading Platform engineering at Renaissance, solving interoperability and identity problems, and scaling LLMs for back-office use cases. Prior to that I built the data function at Alloy from the ground up, leading machine learning, data warehousing and data analysis teams, serving models in production that identified fraud and money laundering in the financial system.

I'm deeply passionate about public education, and dream of a future with a more effective and more equitable systems of schools. In Newark, I had a front-row seat for a particularly bold and contentious period in school reform - you might have read about it! I started my career as a public school teacher in the Bronx through Teach for America, helped found a college prep high school in Newark, and led data, research and technology for the Newark Public Schools.

I'm a product of the University of Chicago. I live in Montgomery, NJ with my amazing, talented wife Kerry and our five children.

I'm the author and maintainer of several open source educational tools, particularly njschooldata, which wraps the hodgepodge of NJ educational data into a consistent, tidy interface you can work with in R.

Ten years on, I'm still carrying a torch for google reader🪦. In the absence of the magic "share with friends" button, I'm the proprieter of weird charts, a love letter to strange and/or captivating charts that I've encountered on the web. I'm also running a podcast curation and sharing project, safe to eat.
