The Faculty of Graduate & Postdoctoral Studies is responsible for the appointment of postdoctoral fellows at Wilfrid Laurier University. The Office provides information, administrative support, and advocacy, as well as helping to facilitate enrolment, placement and training opportunities for postdoctoral fellows. FGPS is dedicated to providing an equitable and sustaining environment for Postdoctoral Fellows, in which they can pursue academic, teaching, and research goals in individual and collaborative contexts, and continue to progress as scholars.

Postdoctoral Fellowships at Laurier are informed by the same core values evident in the university's stated values, vision, and guiding principles. The university's focus on integrated communities of learning and application, cultures of diversity and inclusivity, community and global engagement, the importance of purpose and citizenship, inform the Postdoctoral experience. It is expected that postdoctoral fellows will in turn contribute to Laurier's core principles and institutional domains, as laid out in the Academic Plan 2010-2015.

Regulations, events and opportunities are posted on this website, and current and prospective postdoctoral fellows are encouraged to visit frequently for updates.

Dr Siddhartha Dutta, Postdoctoral Fellow, Biology Chloroplast biogenesis is the fundamental to the productivity mechanism by plants, of which, protein targeting to chloroplast is a prerequisite. Toc159 and the other members of the Toc159 family (e.g. Toc132) serve as the primary receptors. The working model hypothesizes that Toc159 and Toc132 are functionally distinguishable in that they preferentially recognize photosynthetic and non-photosynthetic chloroplast preproteins, respectively. Nevertheless, relatively few chloroplast preproteins have been confirmed as substrates for particular members of the Toc159 family, which limits the proof for the preprotein specificity hypothesis. My current research focuses to expand the number of known preprotein substrates for the Toc159 family of receptor(s) through library screening based on Split-ubiquitin membrane-based yeast two-hybrid system. Initially by using Toc159 G-domain as the bait, and expanding it to include Toc132 and other domains of Toc159 family (i.e. the A-domain), I hope to shed more light on how preprotein substrate selectivity of Toc159/Toc132 is achieved.
