Research Highlights

Welcome to the Research Highlights page!

Here any attendee or presenter at the workshop series can share up to 5 research articles on the topic of time-varying media in order to bring them to the attention of the community. For reasons of space we can only consider submissions from faculty group leaders, tenure-track fellows, and postdoctoral fellows where the work consistitutes an independent research direction. While we welcome research highlight submissions from junior researchers, in the interest of making this page a useful resource for the community we kindly invite all submissions to comply with these guidelines.

If you would like to submit research highlights on behalf of your group, please fill out the form on the research highlight submission page. Submissions will be uploaded approximately weekly, starting on March 17th. Contributions are listed in order of submission.
