Nish Pais - MSc (completed Dec 2010.


MSc. Sept. 2009 to Dec 2011


I completed a BSc. Honours degree in Life Science at McMaster University in 2009. I took courses (Water and the environment & Conservation Biology) that initially sparked my interest in aquatic toxicology and environmental protection. Under Dr. Chris Wood and Dr. Tania Ng's supervision, I completed an undergraduate honours thesis. My project centred on the bioaccumulation and toxicity effects of acute waterborne Cu on freshwater invertebrates. I worked with a variety of invertebrates which included, Lymnaea stagnalis (great pond snails), Lumbriculus variegatus (California blackworms) and Chironomus riparius (bloodworms).

After completing my undergraduate degree, I followed my interests to Wilfrid Laurier University, joining the Integrative Biology Masters program under the supervision of Dr. Jim McGeer. Currently, I am working to further the understanding of using bioaccumulation as a bio-indicator of toxic effects in aquatic environments. I am doing this by relating effects in a sensitive organism (Hyalella azteca), where bioaccumulation can be highly variable, to critical body burdens in resistant organisms (L. stagnalis).

I have served two years as an undergraduate VP finance and volunteer coordinator of McMaster Science for Peace, a chapter of the International Pugwash Society. I also was Biology Graduate Student Association (GSA) President from May to Sept 2010 and currently, I am the treasurer/ secretary for Biology GSA.
