New preprint out on probabilistic control of cell fate in DMD 🔬🎲
Using our insilico framework, we infer dynamic GRN and identify targets to steer differentiation decisions. A nice example of how sys.bio can turn stochasticity into actionable insight.

🚀 Our new Science paper is out (w/ B DeMeo, D Burkhardt, A Shalek, M Cortes): www.science.org/doi/10.1126/...
We show that active learning + transcriptomic perturbations can guide which exps to run next, boosting phenotypic hit rates >13x. AI not just predicting bio, but designing it. 🔁

Catalyzing computational biology research at an academic institute through an interest network Author summary Scientists have widely adopted computing in their research, and the relative importance of computational methods in biology continues to increase. However, a persistent gap exists betwe...

'At the Scripps Research Institute, (...) we created the Computational Biology and Bioinformatics (CBB) affinity group, a trainee-led community for the discussion of computational biology/bioinformatics with the goal of facilitating knowledge exchange.'

GraphVelo allows for accurate inference of multimodal velocities and molecular mechanisms for single cells - Nature Communications RNA velocity offers insight into cell dynamics but faces key limitations across modalities. Here, authors present GraphVelo, a machine learning framework that refines and extends RNA velocity to multi...

RNA velocities provide powerful insights into cell dynamics.
To address current limitations, Jianhua Xing and his lab created GraphVelo, a machine learning framework that extends RNA velocity to multimodal data.
