We wish to extend a very warm welcome to all our current and prospective postdoctoral fellows. Postdoctoral trainees play an essential role in the research activities and life of an academic department. You bring with you important knowledge and skills acquired and honed in other institutions and as such represent a rich and diverse resource. Because postdoctoral fellows hail from a diversity of countries and backgrounds they are by nature important cultural ambassadors. We encourage you to immerse yourself in the life of the department and to avail yourself of opportunities to communicate your experience through mentorship, lectureship and social activity.
