Conferences and Meetings



Check out a slideshow of some photos of our time at conferences over the years…presenting our work, networking with established investigators and other students, enjoying the local scene, and celebrating our various awards.


The lab attends a variety of meetings and conferences sponsored by professional societies, special interest groups, and universities. These gatherings provide an opportunity to present the lab’s most recent work to other experts in the field and stay abreast with others’ most current findings. Additionally, social opportunities abound and time is spent reconnecting with former colleagues and lab alumni. See below for conferences we’ve attended, the title and format of the work that was presented there, any awards we may have won.
