I design high-stakes charts, diagrams, and maps—and publish books and prints celebrating the craft and history of data graphics.
My obsession with data graphics began at the MIT Media Lab. I next learned the power of data work in academic medicine before branching out to serve a broad range of clients. In early 2020, I returned to public health by serving daily graphic reports to The White House. My latest book is Info We Trust, Remastered—a "love letter to data storytelling."
My passion is studying the history of information design. It exposes me to new ways to solve information problems. It also grounds my work in a tradition of people all over the world and all over society who worked hard to better discern reality and create shared understanding.

I host tours of the Andrews Collection of Information Graphics in San Francisco—a working library of rare charts, maps, atlases, and diagrams. Some objects are beautiful examples of craft; others are historically important because they changed how people measured and explained the world.
The collection features many famous designers, including William Playfair, Florence Nightingale, and Charles Joseph Minard. It also contains many important milestones, including the first shaded table, supply-and-demand curves, and Venn diagrams. I have growing sets of statistical atlases and Isotype Institute publications.

My collection is my design library. I study these artifacts to learn composition, emphasis, visual metaphor, and narrative annotation. This practice feeds directly into my professional work: helping teams communicate complex situations clearly, honestly, and with enough nuance to support real decisions.
These rare charts bring me great joy and I am delighted to share my enthusiasm for these graphic wonders through teaching and by hosting visitors to my studio library.
