Simply making data publicly available isn’t enough. We need to make it easy — that requires community buy-in.

I helped create a standard to make it easy to upload, analyze and compare functional MRI data. An ecosystem of tools has since grown up around it, boosting reproducibility and speeding up research.

Chromatin remodeling tied to altered splicing in autism model

Exposing neurons to valproic acid, a well-known environmental risk factor for autism, disrupts their ability to generate different proteins from the same gene.
