Annual report dates come from the budget period on your award notice. That date is not public, so it is not shown here.

How we got this date

NSF lists this award's end date as 28 February 2031.
NSF rules say the final report is due no later than 120 days after that.
So the final report is due by 28 June 2031.

Abstract

Bacteria have the remarkable ability to swim upstream. This motion against fluid flows, called rheotaxis, enables bacteria to invade anatomical tracts and biomedical devices. Upstream swimming can lead to conditions including urinary tract infections and the contamination of catheters. This CAREER project will use experiments and modeling to reveal how bacteria can swim upstream against flows, how bacteria can…
