Hi! I’m David. Ask me what I do, and you’ll get a different answer depending on the day.

So to my fellow Davids: keep one foot in the terminal and one foot in the literature. Validate your outliers. And for the love of all that is holy—. P.S. If you see me staring blankly at a scatter plot at 4 PM, I’m not stuck. I’m just visualizing principal components and questioning my career choices. 😉

Sometimes, I’m a plumber (unclogging data pipelines). Sometimes, a detective (finding a single SNP in 3 billion base pairs). And once a month, I’m a philosopher (arguing whether a p-value of 0.051 is really non-significant).

I’ve learned the hard way that a single misplaced flag in cutadapt can turn your precious RNA-seq reads into biological confetti. My morning ritual? Coffee. htop to see if my server is crying. And grep to make sure my adapter indices didn’t cross-contaminate.

Why ‘rm -rf’ is scarier than a pipette tip, and other truths of digital biology. Introduction: Hello, World (of Omics)

My day doesn’t start with a microscope. It starts with a terminal. Usually, I’m staring at a 50GB FASTQ file that decided to corrupt itself at 2:00 AM.

The first rule of : Always check your checksums.
