It is common to indicate equal contributions with an asterisk (*). In contrast, the principal investigator (PI) under whose guidance the research was conducted is listed as the last author. In interdisciplinary papers, it is common to have more than one PI who substantially guided the research; in this case, equal contributions are indicated as co-corresponding authors (^). In particular, the Human Frontiers in Sciences Program expects all Co-PIs to publish papers together. *=co-first authors ^ = corresponding author(s) Zhu, M., Chen, W., Mirabet, V., Hong, L., Bovio, S., Strauss, S., Schwarz, E.M., Tsugawa, S., Wang, Z.,

2018 Co-organizer of “Polyploidy in organ development, repair, and disease” meeting at the MDI Biological Laboratory, in Bar Harbor, ME with Dr. Don Fox and Dr. Vicki Losick October 13-14, 2018

This meeting brought together researchers working on polyploidy across model systems: fruit fly, worm, plant, fungi, zebrafish, and mammalian models. The meeting topics included the role of polyploidy in organ development, tissue repair and regeneration, cell cycle and chromosome segregation fidelity, size control, and infection and disease. The talks and posters revealed remarkable commonalities across these systems. https://mdibl.org/conference/polyploidy/

High school students Haoxiang Hou Summer 2018 Scientific Outreach: Developed and ran a Computational Image Processing outreach workshop for 7th grade girls entitled “What size is a cell?” through the Explore Your Opportunities program at Mount St. Vincent College in the Bronx, New York (https://westchester-ny.aauw.net/activities/explore-your-opportunities/). The girls play a web-based segmentation program game to guide and correct the computer’s guess for the outline of the cell (http://cose.cacr.caltech.edu/). The program compiles cell size measurements. This follows many years of leading hands-on outreach workshops for middle school girls. 2019 Explore Your Opportunities conference at College of Mount Saint Vincent in the Bronx,
