Ah right, this site also exists. I'll get back to sharing some stuff on here too. But please follow me on Mastodon (@GRvanderPloeg) or BlueSky (@grvanderploeg.bsky.social) instead.

Excited to share that my paper on Parallel Factor Analysis for longitudinal microbiome data has been published in mSystems! It details data rearrangement and processing to uncover microbial dynamics. Check it out: https://t.co/Tx4BEAGXbF

My latest preprint is now available, where we used N-way Partial Least Squares models to study maternal pre-pregnancy BMI and infant growth, revealing complex interactions between mother milk composition and the infant gut microbiome. https://t.co/ftXThiZeHM

I'm excited to share that my R package, parafac4microbiome, is updated to version 1.1.2 on CRAN: https://t.co/lmMi1kEAkm. This release features the full dataset from vanderPloeg2024 (https://t.co/CoMQxj9osp), an improved CORCONDIA, updated vignettes, and much more! #RStats

I presented my poster today at the Amsterdam Microbiome Expertise Center (AMEC) day at Artis zoo. I'm excited to share it here too. Feel free to message me with any questions! #AMEC2025 #Microbiome #DataAnalysis

(8/8) I hope that this was helpful. If you got this far, thank you very much for your interest. Feel free to DM me if you have any questions. Also check out my paper (https://t.co/8sIfbGcDAi) and the parafac4microbiome R package (https://t.co/YBWThsoB8P) for more details.

Here's a thread 🧵 on using the parafac4microbiome package to track microbial changes with tensors over time. Check out my paper (https://t.co/8sIfbGcDAi) and the parafac4microbiome R package (https://t.co/YBWThsoB8P) for more details. #RStats

(7/8) PARAFAC reveals distinct microbial growth patterns: Proteobacteria show exponential growth in case subjects, while Actinobacteria exhibit a sigmoid growth curve in controls. This method interprets time-resolved microbial differences between groups more effectively than PCA.

My second paper on applying Parallel Factor Analysis (PARAFAC) to microbiome datasets is submitted and available on @biorxivpreprint: https://t.co/dlQPI81Qq8. It features my R package, parafac4microbiome, downloadable from CRAN: https://t.co/ojrXVHAcQD.

Thrilled to share my 1st paper in @NaturePortfolio npj Biofilms & Microbiomes! We show how Parallel Factor Analysis reveals microbial subcommunities & pathways in gingivitis. Thanks to my coauthors!

I thoroughly enjoyed making an R package that create Parallel Factor Analysis (PARAFAC) models for longitudinal microbiome data analysis. Learn more about it on https://t.co/aCmPAVI97F or my preprint at https://t.co/tFgPMpSnKi #Microbiome #Bioinformatics #DataScience #RStats

Happy to share that my personal website https://t.co/DEGxbI0T8P is live. You can view my CV, publications and presentations on there if you're interested.

[Roel van der Ploeg @GRvanderPloeg]

As a data scientist, it feels great to have multiple servers & computers running my analyses at the same time! This might be the best way to multi-task! 😄
