Current Graduate Students

Paulina Bahamonde Cárdenas

(Co-supervised with Kelly Munkittrick)

MSc Candidate

The impact of wastewater discharges on ecosystem health.

Meghan Doyle

MSc Candidate

The effects of ethinylestradiol (EE2) on molecular signalling cascades in mummichog (Fundulus heteroclitus).

Jennifer Loughery PhD Candidate

Linking gene impacts to organ and individual level changes: PAHs as a case study.

Joshua Marr MSc Candidate Characterizing molecular responses in steroidogenesis of the fathead minnow (Pimephales promelas) testes to a potential anti-androgen, the phenyl-ureic herbicide linuron

Anna Ornostay

MSc Candidate

In vitro analysis to examine the effects of ureic-based herbicides on steroidogenic signalling cascades in fathead minnow (Pimephales promelas) ovary.

Potential Opportunities for Graduate Students

The laboratory of Dr. Martyniuk (UNB in Saint John) is seeking a highly motivated PhD student (or MSc) with an interest in aquatic ecotoxicogenomics to commence September 2012 or January 2013.  My research program uses molecular tools (genomics and proteomics) to characterize mechanisms of toxicity in order to better understand organism-environment interactions. Projects will be developed using the fathead minnow as a model to assess the effects of endocrine disrupting chemicals on fish reproduction. The graduate student will learn to apply molecular tools to study ecological issues.  The expected level of contribution is commensurate with the degree being sought.  Experience in molecular biology is an asset but is not a requirement. Please contact Dr. Chris Martyniuk at for additional information about projects and opportunities.
