Alexander Douglas

Alexander J. Douglas

MSc Student

I joined the lab in Sept 2018 as an Undergraduate Honours Thesis Student and my research focuses on the skin microbiome of the North American wood frog.

I enjoy hiking, swimming, and skiing in my free time. While indoors I spend my time reading science fiction, or growing and caring for various plants, animals and fungi.

Undergraduate Honours Thesis Student

My Undergraduate Honours Thesis research aims to characterize pattern recognition receptor (PRR) expressions and functionality in two Xenopus laevis skin epithelial cell lines.  I plan to investigate the functionality of the PRRs upon stimulation with synthetic pathogen associated molecular patterns (PAMPs) such as Poly(I:C) in order to evaluate and compare frog skin cell susceptibility and resist


Simi (Jasmin) Zhang

Undergraduate Honours Thesis Student

My undergraduate research will focus on the antiviral properties of brevinin-1SY, an antimicrobial peptide isolated from wood frogs (Rana sylvatica), against frog virus 3 (FV3).

Undergraduate Honours Thesis Student

My Undergraduate Honours Thesis will focus on elucidating the mechanism of cell death of Xenopus laevis epithelial cells in response to pathogen challenge. I plan to determine the mechanism of cell death in response to Frog Virus 3 (FV3) challenge, and supernatants from Batrachochytrium dendrobatidis (Bd) and Batrachochytrium salamandrivorans (Bsal).
