The Université de Montréal’s Department of Biological Sciences will hold its XXIInd Symposium from April 3-5, 2012. This year’s theme is “A World in rEvolution”. The objective of this activity is to familiarize biology students from the host university and other Montreal academic institutions with research in progress in the Department’s laboratories. The Symposium also offers a venue for the Department’s researchers to spotlight their laboratory projects. Undergraduate and graduate students who have completed a project in the context of an introductory research course and/or in a work-study program, as well as faculty, are invited to present recent findings.
