I’m Kayla Sox. I work in biotech. I write code. I wear gloves sometimes. I keep a lab notebook and a lot of sticky notes. This is my honest review of data science in biotech, as someone who uses it every day. It’s not one thing. It’s a toolbox. For a rigorous academic perspective on just how wide that toolbox can be, you can skim this detailed review of data science in biotechnology. And yeah, it can save time and money. It can also make a mess if you’re not careful.
What I actually use, like for real
Here’s my daily stack. Nothing fancy. Just things that work:
- Python (pandas, scikit-learn, matplotlib)
- R with Seurat and tidyverse
- Jupyter and VS Code
- Nextflow for pipelines (and a few Snakemake bits)
- Docker to keep runs the same
- AWS S3 and EC2 (Spot when I can)
- Cell Ranger for single-cell data
- STAR, Salmon, and MultiQC for bulk RNA-seq
- Benchling for notes and tracking
- RDKit and DeepChem for chemistry work
- AutoDock Vina and Rosetta for docking
- CRISPOR and GuideScan for CRISPR guides
- CellProfiler for image data
If you’re hunting for extra tips on squeezing performance out of pipelines that juggle petabytes like pipettes, the concise write-ups at vhfdx.net are surprisingly on point. For an even deeper dive into how those ideas play out at the bench, you can skim this equally candid hands-on field review that digs into tool choice and lab realities.
You know what? This stack is like a good lab bench. If it’s clean, you move fast. If not, you trip on cables.
Real Project 1: Single-Cell RNA-Seq That Changed a Target List
We had 12 lung tumor samples. Two runs on an Illumina NextSeq. I used Cell Ranger for the raw reads. Then Seurat in R to cluster cells. The batches did not play nice at first. I used Harmony to fix it (batch effects, ugh). After that, the clusters were crisp.
We found a clear macrophage group that was high in SPP1 (osteopontin). We saw SIGLEC10 and CD163 up, too. That pointed us to a “don’t eat me” axis. The team got excited. I built a simple MAST model for differential expression. We cut our target list from 51 to 7. Two targets made it through to wet lab tests. In a basic phagocytosis assay, both showed a solid increase in uptake. Not huge, but real. It felt good.
Time win: with a Nextflow pipeline and AWS, the full run went from 3 days to about 8 hours. Cost per run went from around $180 to $42. Small lab, big cheer.
Real Project 2: CRISPR Guides That Did Not Wreck the Genome
We needed to edit TYK2 in primary cells. I used CRISPOR and GuideScan to score guides. I filtered for GC around 45–55%. I kept off-target hits low. One guide looked hot but had a scary off-target near a tumor suppressor. We tossed it, even though the score was shiny.
We did rhAmpSeq to check edits. On-target indels were about 78% on average. Off-target events stayed under 0.1% in our top 3 guides. That saved us weeks of cleanup. Honestly, the hardest part was naming files right. Yes, I used DVC to track versions. Yes, I learned that lesson the hard way once.
Real Project 3: Antibody Binder Picks with a Small Model That Punched Up
We had binding data from ELISA and BLI for a panel of variants. I pulled features from sequences with simple stats and some RDKit bits for the small molecule part of the screen. I trained XGBoost. Nothing wild. I used 5-fold CV and a strict time split to avoid leakage.
Baseline AUC was 0.62. With better features and class weights, I got it to 0.81. Docking with AutoDock Vina helped rank ties. ColabFold gave us rough structure hints, which made our chemist smile, though we all know it’s a guide, not gospel.
Hit rate in the next wet lab round jumped from 3% to 11%. That moved the team forward two sprints. We still had false positives. That’s life. But we wasted less bench time, and that matters.
Real Project 4: Bulk RNA-Seq, Now With Fewer Tears
I built a Nextflow pipeline for bulk RNA-seq. It ran FastQC, Trim Galore, STAR, Salmon, and then MultiQC at the end. I wrapped it all in Docker. Everyone got the same results, every time. I used AWS Spot to cut costs. When nodes died, the pipeline resumed fine. If you want a practical diary of what it’s like to live with a production workflow for twelve straight months, this no-fluff year-long pipeline reality check might resonate. For a broader discussion of why such workflows are becoming standard across the sciences, check out this Harvard Data Science Review essay.
Before the pipeline, a run took 2–3 days. After, it took about 6–9 hours, even with large batches. We caught weird runs fast by looking at mapping rates and Q30 scores in MultiQC. Low Q30? We paused the lab plan and saved reagents. No one loves to stop a run. But it’s better than chasing ghosts for a week.
A small image story: when cells tell you the truth
We screened a 384-well plate with a new compound set. I used CellProfiler to get features from the images. Then a random forest to flag wells that looked “weird” in a good way. It pointed to 14 wells we would’ve missed. Four of those turned into real hits after follow-up. I didn’t expect that. But the cells were basically waving at us.
What feels great
- Speed: Good pipelines turn days into hours.
- Clarity: Single-cell tools like Seurat make cell types pop.
- Repro: Docker and DVC keep runs sane.
- Money: Spot instances and simple models save real dollars.
- Team flow: Benchling plus clean reports keeps science moving.
What makes me groan
- Messy data: Bad metadata breaks hearts.
- Overfitting: A pretty curve can still lie.
- Batch effects: They sneak in like glitter. Hard to shake.
- File names: One wrong underscore, and I’m lost.
- Tool sprawl: Too many packages; not all play nice.
A quick workflow I trust
- Plan: Write the question in one line. Tape it to the monitor.
- QC first: FastQC/MultiQC, always.
- Simple model first: Baseline, then add.
- Split right: No leakage. Time or donor-based splits help.
- Version it: Code, data, and params.
- Report: One page, clear charts, plain words.
- Validate in the lab: Stats don’t pipette.
Who should use this toolbox?
- Small biotechs: Yes. Start with Python, R, Docker, and a modest cloud setup.
- Academic labs: Yes. Jupyter, Seurat, and Cell Ranger go far.
- Big pharma: You’re already doing it, but please, keep metadata clean.

If you’re brand new, start with one project. Maybe a small RNA-seq set or a simple image screen. Keep a strict folder plan. Write down every version number. It feels slow at first. Then it feels fast, because you stop redoing the same work.
Science teams are made of people, and people chat. Whether it’s Slack threads about aligner flags or more personal DMs after hours, the conversation eventually shifts platforms. If you ever fire up Kik for something a bit more flirty, the no-nonsense rundown in this Kik sexting guide explains how to keep those exchanges safe, consensual, and screenshot-proof so you can unwind without tech-induced anxiety.

My verdict
Data science in biotech is not magic. It’s a sharp tool. In my hands, it has picked better targets, cut waste, and saved days. It also bites if you rush.
Rating: 4.5 out of 5. It would be 5
