I have a conference coming up in two weeks, the American Society of Human Genetics (ASHG), where I will be presenting a technical poster in the bioinformatics section. The code behind the graphs will be on my github here. For this post I'd like to focus on my ggplot code rather than the science, so... Continue Reading →
Accessing GTEx V7/V8 raw RNA-Seq data in the cloud
Hi all, since I posted an answer on Biostars about how to access the raw RNA-Seq GTEx data (The Genotype-Tissue Expression Consortium), I have fielded questions from researchers at many institutions asking for more information. Disclaimer, I am not part of the Sequence Read Archive staff or the National Library of Medicine. But I seem... Continue Reading →

Forget-me-not
A messy photomanipulation for fun, with two base images as usual: a student walking between ruined buildings, and a macro of forget-me-not flowers. Spilled color / burnt film texture and a moiré underpainting (last image in series). Embracing both inherent blur and rough bucket-fill edges. Looking forward to spring. Listening to: Accensor
Annapurna Circuit
Another piece with nature + technology elements, this time with a Motorola MC68012 processor from the 80s and a sweeping view of the Annapurna mountains. I have made many pieces like this before, almost identically, but haven't tired of it yet. It is an easy escape: The moiré waves overflow off the edges of a landscape... Continue Reading →
Motherboard + chicory
Statement: An old ASUS motherboard photo plus a chicory inflorescence. First full image is flush with vitality and movement, while the next is a deconstruction to evoke torn up flowers and fabric. Maybe this is a botanical pressing saved to file, then excavated and found to be corrupt later. A realistic cyberpunk future would be... Continue Reading →
Now at NCATS NIH!
Just a quick update for those who have not heard yet, I am now working at the National Center for Advancing Translational Sciences (NCATS) at the National Institutes of Health (NIH), employed through Kelly Services as a contractor. I am in Dr. Ilyas Singeç's stem cell technology lab as a bioinformatics support and data science... Continue Reading →
Weather system approach
New art made in an afternoon. I found a CC0 photo site (public domain Creative Commons) so naturally I found a good landscape + clouds photo for making good old fashioned digital art. https://pxhere.com Aesthetic: fruit salad - watermelon, blood oranges, blackberries highly pigmented watercolors with color bleeds partially destroyed photos strong winds sudden drop...

If you can for-each, you can doParallel! Parallelization in R
One of the common complaints I hear about R as a data analysis language is its relatively slow speed, compared to the C at its foundation or other, lower-level programming languages (C family, java, fortran). For-loops can be incredibly slow! They do get the job done eventually, serially (one task at a time), instead of... Continue Reading →
2018 programming goals: SAS, R, python
Featured image: "Midnight," digital art I made in 2014. Moiré exclusion patterns are created from layering multiple photographs of a LCD screen. Bands of solid color are from certain non-proportionally stretched layers in the vertical direction. Hi all! It's been a hot minute since I updated here. A lot of big events have happened, ranging...
