Open Software/Data

I am committed to making software I develop and data I collect freely available, in the spirit of open access, to minimize repeated effort among investigators, and to ensure that the results in my publications can be reproduced by others. I believe that openly sharing scientific workflows and datasets will speed up scientific progress and increase the contributions of underrepresented and historically excluded groups to scientific research.
