Please click here to download a slide you will use to introduce yourself to the group. Please stay within the space allotted for each question; you will only have one minute to present your slide to the group. For the image, you may add a microscope image you have acquired or another image that is reflective of your research. Please return your completed slide to firstname.lastname@example.org by Monday, Sept 12 with the subject line ILA 2022 Introduction Slide.
You should use this version even if you already have Fiji installed on your laptop.
Do not update Fiji after installation.
