Dr. Allison McDonald

I've been at Laurier since July 2010.

Prior to joining Laurier, I was a postdoctoral fellow in the Department of Biology at Western University (2008-2010).

I received my PhD in Cell and Systems Biology from the University of Toronto Scarborough in 2007 and my MSc in Biology from Queen’s University in 2000.

My lab focuses on the electron transport systems of photosynthesis and respiration. Our particular interest is alternative proteins involved in putting electrons into or taking electrons out of these systems. Current research projects focus on the alternative oxidase, plastoquinol terminal oxidase, and alternative NAD(P)H dehydrogenases of bacteria, fungi, protists, plants and animals. We use various techniques to study the molecular, regulatory, and functional properties of these enzymes. I also have a strong interest in scholarship about women in science, science communication, and the professional development of graduate students and post-doctoral fellows.

• Natural Sciences and Engineering Research Council Post-doctoral Fellowship (2008-2010).

Potential Undergraduate Thesis Projects Available:

Undergraduate students interested in conducting an undergraduate research thesis (Biology, Chemistry and Biochemistry, or Health Sciences) should contact me by email at amcdonald@wlu.ca. I will be recruiting thesis students for September 2024 in February of 2024.

Recruiting M.Sc. and Ph.D. students for 2024:

The McDonald lab is currently recruiting Canadian MSc and PhD students for January 2024 or beyond.

Our lab focuses on the respiratory electron transport system and our particular interest is the alternative oxidase protein. Research projects focus on the alternative oxidases of bacteria, fungi, plants, and animals. We strive to do excellent science and have fun while doing it! I take a strong interest in my students’ professional development and encourage them to maintain a positive work-life balance.

 Position Requirements

Previous experience in a laboratory setting working on your own research project (e.g. Directed Studies, Honours Thesis, grad degree) is required. I am looking for students who are kind, proactive, self-motivated, curious, and persistent. Excellent oral and written communication skills are required. The ability to work independently and as a member of a diverse research team is necessary. Strong attention to detail, the ability to follow instructions, the ability to creatively solve problems, and the ability to work safely are required.

Position Funding

Funding is guaranteed for 6 terms of study in our Master’s program in Integrative Biology. Funding is guaranteed for 12 terms of study in our Ph.D. in Biological and Chemical Sciences. Our stipends are funded through teaching assistantships, university scholarships, and research assistantships paid by the supervisor. Due to funding constraints only Canadian students will be considered.

Position Location

Wilfrid Laurier University is a growing institution in Waterloo, Ontario. The city of Waterloo is a thriving community and technology hub centrally situated in southwestern Ontario with access to other large metropolitan areas including Guelph, London, Hamilton, and Toronto. The Biology department is a tight-knit community and offers many opportunities for collaborations and research support. Graduate student research at Laurier is question driven and uses a variety of techniques and approaches to answer hypotheses through investigation at multiple levels of biology (e.g. molecular, cellular, physiological, ecological, evolutionary). Our students leave our programs with a solid biological background, the ability to use critical thinking to address important challenges and issues, and are prepared to succeed in a variety of career paths.

How to Apply

If this sounds like the environment for you, please provide a record of your undergraduate/graduate transcripts, a CV or resume, a 500 word statement about why you want to pursue a graduate degree in the McDonald lab, and the names of two academic references to amcdonald@wlu.ca.
