Leadership Team

Daniela Saderi, Ph.D. – Co-Founder, Director

Daniela has a Ph.D. in Neuroscience during which she studied mechanisms of auditory processing in mammals. As the project Director at PREreview she is responsible for overall project oversight, product development and management, fundraising, and internal and external communication. During her time as a student, she became increasingly interested in how open practices can be used to empower early-career researchers in taking ownership over their work, and to facilitate collaborations within and across teams. This passion, combined with active community engagement, led her to co-found PREreview in 2017 and become a Mozilla Fellow for Science in 2018/2019.


Samantha Hindle, Ph.D. – Co-Founder, PREreview Open Reviewers Program Lead

Sam has a Ph.D. in Neuroscience where she characterized neurodegenerative disorders in Drosophila. During her postdoctoral position studying the Drosophila blood-brain barrier, she became increasingly passionate about open science and the potential for preprints to rewrite the way scientists disseminate their research.  Following her passion for preprints, Sam became the Content Lead at bioRxiv and now manages the preprint content teams at CSHL. Her advocacy for the use of preprints began with her early engagement with the ASAPbio Ambassadors and Mozilla communities, paths that led her to co-found PREreview in 2017. Sam leads the PREreview Open Reviewers Program, providing ECRs with access to important training and networks to excel in their peer reviewing opportunities.
