I wrote a short piece on what funding and hiring committees often overlook when assessing merit. @academic-chatter.bsky.social

✨New post ✨ Here I describe how I make maps in #ggplot2 from the GeoJSON, Shapefile, GeoPackage, and geodatabase formats 🗺️. I'll go a bit into projections and data wrangling of geospatial data. Hope it is of some use to some! 😊 danielroelfs.com/posts/advanc...

✨New blog post✨ I break down the beautiful data visualizations from a New America report (cowritten by @oscarp.bsky.social) and try to recreate them in R using ggplot2. danielroelfs.com/posts/new-am...

My students and average people are often surprised to learn that academics pay a fee to publish a open-access paper in a journal, and _always_ surprised to learn that those fees can be as high as $12000 USD. #acadsky danielroelfs.com/posts/the-mo... @danielroelfs.com

I absolutely adore reveal.js. I've used it as my main slideshow tool for the past years. If you know a bit of HTML/CSS it's super easy to create beautiful and dynamic slides (+ Quarto integration <3). I wrote a short post about my enthusiasm here: danielroelfs.com/posts/ode-to...

✨New blog post✨ Remote sensing of vineyard health 🍇 I felt inspired by a data visualization exhibition I visited a while ago and decided to try my hand at remote sensing and analyzed some satellite images in Python. danielroelfs.com/posts/remote...

This week on What's New in R: ✅ A new R package by Joey Marshall for accessing elevation data ✅ Overview of what’s new in R 4.5, compiled by Russ Hyde of Jumping Rivers ✅ A guide to replicating Financial Times-style data visualizations, by Daniel Roelfs Read the issue: buff.ly/Y4HwU4g #rstats

I admire John Burn-Murdoch's ability to create really effective data visualizations. So much that I took the liberty of breaking down one of his recent figures that made the rounds and see if I could recreate it in R using only ggplot. Here's the breakdown: danielroelfs.com/blog/financi...

Anyone that uses Strava has access to a large, self-generated (!), dataset 🧡. And at the end of the year it's quite fun to try to parse something interesting and relevant from that dataset: danielroelfs.com/blog/strava-...

🚨 This will become a curated list of awesome tools for complex trait genetics, **add yours**! it may become a review in which case those who contribute are invited as co-authors.

Last Tuesday I defended my PhD in computational neuroscience and psychiatric genetics 🥳 PhD theses are rarely read outside of the supervisors and committee, so I tried to write it in an accessible way and published a digital version here: thesis.danielroelfs.app - Daniel Roelfs, PhD

Mendelian randomization users, what should I call a polygenic score created for and used with MR? I find PGS/PGI confusing to newcomers as not all ways of creating a PGS will do. Would it be clearer to call this score an allelic score instead? Or something else?

It's hard to explain why scientific publishers like Elsevier and Springer-Nature make the kind of money they do. So hard that I did the data analysis and wrote it down so I could easily share it and perhaps help others understand how broken the system is: danielroelfs.com/blog/the-mon...

Our latest paper is now published in Nature Mental Health ✨ We applied a multivariate GWAS implemented through the Bayesian framework in MOSTest on UK Biobank fMRI data and found widespread overlap with psychiatric disorders www.nature.com/articles/s44...

Are people (and neuroscientists in particular) aware that that the SfN chair has a total compensation of about $960.000? That's about 4% of total revenue. I've left academia a while ago and Twitter is terrible since the takeover so maybe I missed some discourse, but it feels that's a lot? Source:
