Hierarchical Data in Mathematica DataFrame-like construct for data science workflows For Mathematica 11, I contributed the the new Dataset construct in Mathematica, which acts as a flexible container for tabular data. It involved a lot of interesting challenges around automated layout and deduction of types from unstructured data. The underlying technology scales to quite complicated nested use of Mathematica’s two native data structures, being lists $\{v_1,v_2,...\}$ and associations $\left<\left| k_1 \to v_1,k_2 \to v_2,... \right|\right>$. Because Mathematica is a …

One of the my favorite projects was working with the artist Elizabeth Latta to visualize and computationally explore the famous Shakespeare play The Tempest. Among the many promising ideas we investigated, two in particular were interesting enough that I’d like to show them off. The beautiful drawings are Elizabeth’s work, and I planned and wrote the code. …
