Evan Pacey (Ph. D. candidate)

I received my BSc from the University of Western Ontario in 2010 and my MSc from McMaster University in 2013. Towards the end of my Masters I started analyzing genome size databases for physiological trends. One trend that became apparent was that polyploid organisms often inhabit more resource-limited environments than their diploid progenitors or relatives. I hypothesize that this trend exists because polyploids can store more per unit volume than diploids. I am testing this hypothesis with numerous accessions and cytotypes of Arabidopsis thaliana.
