I seek to study the filamentary structure of the cosmic web, from the largest scales down to the central hubs — massive galaxy clusters. My tool of choice is gravitational lensing, in particular weak lensing. I’m a member of the CLASH team and the Dark Energy Survey collaboration.
I’m also running the website PaperRater.org, which enables open review of papers as they appear on arXiv or in peer-reviewed journals. It’s primary idea is to leverage the collective knowledge of the research community to judge the quality and relevance of papers. Thereby we can augment the classical peer-review process and publicly acknowledge the service of good review. You can follow the progress of the project on its blog.
