I present clearly, connect broadly, spark imagination and encourage enthusiasm for inquiry. I create visuals with analytical clarity and artistic dimensions.
In 1999 I built the Genome Sciences Centre's first computing systems, and later invented port knocking, and optimized keyboard layouts that spawned a Brazilian fashion line. I have an affinity for parody and tragedy. I love rabbit holes.
I created Circos (a community standard) and hive plots (a farewell to hairballs). I am triggered by slipshod visualizations of science and pie charts.
My information graphics have appeared in the New York Times, Wired, and on covers of books and scientific journals such as Science, Nature and PNAS.
I am a co-author of the Nature Methods Points of Significance and Points of View columns. I contribute to Scientific American's Graphic Science and teach how to design scientific figures and scientific posters. My method is critique by redesign.
I’ve made maps of nothings in the Universe, shot fashion photography, found poems in spam. Every year I make Pi Day art, which can be graphics, words or music. I made a music video about infinity, I love typography and run Hitchmas.
I am a former owner of Alex, the world’s most popular rat.

Circos is software that generates circularly composited views of genomic data and annotations.
Figures created by Circos are engaging, pretty and informative.
Circos is particularly suited for visualizing alignments, conservation and intra and inter-chromosomal relationships. (presentations on Circos; drawn heavily from Tufte's Visual Display of Quantitative Information)
Hive plots are a type of layout algorithm that is designed to make sense out of very large networks. The method is quantitative — placement of nodes depends only on network properties.
Hive plots are an answer to the challenge of uninformative network hairball visualization.
I had the opportunity to design the cover of the Genome Informatics Conference program book. The cover shows sequences of some of the genes and viruses that appear in this conference's abstracts and uses the genome path algorithm previously used in the Deadly Genomes poster.
The Deadly Genomes is a visualization of the size and structure of genomes of viruses and bacteria that are agents of prevalent human diseases. Their genomes are visualized as a path, and each organism is spaced on the poster according to the incidence and mortality of the disease.
This image reached the finalist stage at the 2009 National Science Foundation Visualization Challenge.
December 2009 saw the 10th Anniversary of the Genome Sciences Center. Some commemorative swag was handed out, among which was a stainless steel water bottle with the following image.
The image contains a barcode called QR Code (learn more) which encodes the names of all current employees at the Center.
Lexical analysis of 2008 US Presidential and Vice-Presidential Debates indicates that the speech patterns between candidates (especially those paired in a debate) are extremely similar and that the complexity of vice-presidential candidates is lower than presidential candidates (uniqueness is lower, repetition is higher).
Palin has the longest sentences, Biden repeats himself the most and has the smallest vocabulary, while patterns for Obama and McCain are eerily similar.
Use Atom feeds of candidates' word lists to create Wordles.
carpalx is a keyboard optimizer which rearranges letter positions on a keyboard to minimize typing effort. Discover the magical XBUL keyboard layouts which minimizes typing of English text. Or, if you dare, venture into the land of the disfigured TNWCLR keyboard layout which makes typing English text excruciatingly painful.
High Dynamic Time Range images (HDTR) are single-frame composites of a set of time-lapse photos.
The bioinformatics Perl workshop offers courses to help you learn Perl and apply it to your work. We have courses on introductory Perl, intermediate Perl, and others. Learn how to use map, grep and sort more efficiently or how to perform data analysis at the command line. The workshop is open to the public (given at the GSC 570 W 7th location) and all slides from each lecture are available online.

Image color summarizer produces statistics about an image's mean/median hue, saturation and intensity values. It's fun to play with and can be (eventually) used to auto-tag images based on color content.

In the first of a series of columns about neural networks, we introduce them with an intuitive approach that draws from our discussion about logistic regression.
Simple neural networks are just a chain of linear regressions. And, although neural network models can get very complicated, their essence can be understood in terms of relatively basic principles.
We show how neural network components (neurons) can be arranged in the network and discuss the ideas of hidden layers. Using a simple data set we show how even a 3-neuron neural network can already model relatively complicated data patterns.

My cover design on the 6 January 2023 Science Advances issue depicts DNA sequencing read translation in high-dimensional space. The image showss 672 bases of sequencing barcodes generated by three different single-cell RNA sequencing platforms were encoded as oriented triangles on the faces of three 7-dimensional cubes.

In a follow-up to our Survival analysis — time-to-event data and censoring article, we look at how regression can be used to account for additional risk factors in survival analysis.
We explore accelerated failure time regression (AFTR) and the Cox Proportional Hazards model (Cox PH).

My 5-dimensional animation sets the visual stage for Max Cooper's Ascent from the album Unspoken Words. I have previously collaborated with Max on telling a story about infinity for his Yearning for the Infinite album.
I provide a walkthrough the video, describe the animation system I created to generate the frames, and show you all the keyframes
