Nick is the author of two R packages and has 12 published papers in the Statistics, Medical sciences, and Physics fields. In his free time, Nick enjoys a good coffee, comedy, and greeting dogs.

Nicholas is the author two R packages, spinifex and cheem. Spinifex implements user-control of the basis in animated linear projections. Cheem uses this visualization method to explore the interpretability of machine learning models. My thesis is titled Interactive and dynamic visualization of high-dimensional data
