The Moorhead Lab

Studying cell signalling events controlled by protein phosphorylation in the model plant Arabidopsis thaliana.

Principal Investigator: Dr. Greg Moorhead

I concluded my Bachelor of Science at Queen's University in Kingston, Ontario before completing a PhD with Dr. Bill Plaxton (Queen's) in Plant Biochemistry. After graduation, I began my post-doctoral studies under the guidance of Sir Philip Cohen at the University of Dundee (Dundee, Scotland) where I studied mammalian protein phosphatases. I then began working with Dr. Carol MacKintosh (University of Dundee) on plant nitrate reductases and 14-3-3 proteins. 

I joined the department of Biological Sciences biochemistry group at the University of Calgary in 1998. My current research looks into signalling pathways regulated by protein kinases and protein phosphatases in the model plant Arabidopsis thaliana.

Jayde Johnson - PhD Candidate

I completed my undergraduate degree here at the University of Calgary earning a BSc (Honours) in Biochemistry. My research career began with an undergraduate 530 project supervised by Dr. Moorhead where I focused on purifying the protein phosphatase Shewanella-like protein phosphatase 1 (SLP1). My graduate project now focuses on how SLP1 is regulated in the chloroplast of Arabidopsis thaliana. When I am not in the lab you can probably find me playing baseball or volleyball. I also enjoy outdoor activities like hiking, camping, and snowshoeing.

In 2020, I completed my undergraduate degree in Biochemistry at the University of Calgary during which I did an independent research project under the guidance of Dr. Greg Moorhead. The experience I garnered at that time ultimately lead to me to staying in the Moorhead lab to begin my Master’s in the Fall of 2020. My research is focused on the plant protein phosphatase Shewanella-like phosphatase 2 (SLP2) in Arabidopsis thaliana and its role in cellular signalling.

Chris White-Gloria - PhD Candidate

In 2018, I graduated from the University of Calgary with a Bachelor of Science (Biochemistry). However, I had been working as an undergraduate summer researcher in Dr. Moorhead's lab for the two years prior. It was initially the Shewanella-like protein phosphatase-1 and -2 (SLP1/SLP2) projects that piqued my interest during my senior thesis and summer internships. I am now continuing my work on SLP1 by doing a Masters with Dr. Moorhead's group. My project is focused on cell signalling events controlled by SLP1 in the chloroplast.

I graduated from the University of Calgary with an Honors Biochemistry degree in 2020 and I'm currently doing my Masters in Dr. Moorhead's group. My research involves studying the interaction between the protein phosphatases, RLPH2 and PP1, with the D group MPKs from Arabidopsis thaliana. Other than a love for protein work, I have a passion for travelling and was very fortunate to be able to go to Greece in 2018. I am hoping to travel to other places soon!

I started working in Dr. Moorhead's lab in the summer of 2020 as an undergraduate researcher. I am now a fourth year Biochemistry student working on my undergraduate 530 project. The focus of my thesis is on purifying recombinant Shewanella-like protein phosphatase 1 (SLP1) constructs for structural analysis by X-ray crystallography. I also enjoy golf and am a member of the Dinos golf team.
