I am super excited to announce that I will be starting my lab at the Department of Pharmacology of the University of Zurich in Switzerland next year!

chatomics! Bioinformatics is NOT Just Statistics! 🚨 The p-value is small in this example, but is it biologically meaningful?

New deep-learning cell detection pipeline for light-sheet mouse brain image stacks, with an interesting cell-coordinate clustering statistics approach: A deep learning pipeline for three-dimensional brain-wide mapping of local neuronal ensembles in teravoxel […] [Original post on mstdn.science]

Fig. 1 a–c, Intact whole brains immunolabeled, cleared and imaged with LSFM were used as input to the ACE pipeline. a, Whole-brain LSFM data are passed to ACE’s segmentation module, consisting of ViT- and CNN-based DL models, to generate binary segmentation maps in addition to a voxel-wise uncertainty map for estimation of model confidence. b, The autofluorescence channel of data is passed to the registration module, consisting of MIRACL registration algorithms, to register to a template brain such as the Allen Mouse Brain Reference Atlas (ARA). High-resolution segmentation maps are then voxelized using a convolution filter and warped to the ARA (10 µm) using deformations obtained from registration. c, Voxelized and warped segmentation maps are passed to ACE’s statistics module. Group-wise heatmaps of neuronal density are obtained by subtracting the average of warped and voxelized segmentation maps in each group to identify neural activity hotspots. To identify significant localized group-wise differences in neuronal activity in an atlas-agnostic manner, a cluster-wise, threshold-free cluster enhancement permutation analysis (using group-wise ANOVA) is conducted. The resulting P value map represents clusters showing significant differences between groups. Correspondingly, ACE outputs a table summarizing these clusters, including their volumes and the portion of each brain region included in each cluster.

Just got back from the 2nd Pertomics Retreat with my colleagues @shawangela.bsky.social and @thorohde.bsky.social — Great to reconnect with the Pertomics community, share work across different scales. Special thanks to @manuelkaulich.bsky.social ’s fantastic team for organizing this great event.

@thorohde.bsky.social · last yr.

I am excited to announce the publication of our paper in @molsystbiol.org! I am incredibly grateful for this wonderful collaboration with the team of @manuelkaulich.bsky.social. A big thank you to @yasirde.bsky.social, @shawangela.bsky.social and to @maxbillmann.bsky.social! doi.org/10.1038/s443...

Just back from the CRISPR and Beyond — Loved being back in Cambridge with the CRISPR community. It was great to see familiar faces from last year and catch up on the latest developments.(especially members of @manuelkaulich.bsky.social, @leopoldparts.bsky.social 's group). #WellcomeGenomeCampus
