Sunday, Nov. 13 - Early Career Symposium


The Early Career Symposium (ECS) takes place before the 2022 ASM Conference on Biofilms starts. The symposium allows trainees to share their work and network with other early-career scientists in an informal setting separate from the main conference. Participants will have the opportunity to give research talks and hear from 2 invited faculty speakers, a senior PI with a history of successful trainees and an early-career PI who has recently transitioned to independence.

The ECS is for trainees and by trainees, with the entire organizing committee comprised of graduate students and post-docs. There is an additional fee of $25 to attend this program. Sign up during registration.

Sponsored by The Mark Shirtliff Foundation

Optional Workshop

Tuesday, Nov. 15—Biofilm Imaging Workshop—Sold Out


Are you interested in taking your biofilm analysis to the level of high resolution, quantifiable microscopy? ASM Biofilms has organized an optional workshop for image analysis of biofilm microscopy for the afternoon/early evening of Tuesday, Nov. 15.

Experts in biofilm image analysis will discuss the importance of image analysis and quantification to maximize the statistical rigor of your images. We will walk you through the analysis of example multichannel 3D (XYZ) and 4D (XYZT) confocal data sets using the freely available biofilm image analysis programs COMSTAT and BiofilmQ. We will provide instructions for downloading and installing them before the workshop. To participate in the workshop, attendees will need to bring their laptops capable of running the software (MATLAB-based), but we will provide test images and data. Attendees may also be able to utilize their own data sets. Seats are limited, so sign up early. There will be an additional fee to participate in this workshop.
