Ph.D. position in acid-base regulation and osmoregulation  

Job Description

 

Job Title: Ph.D. position in acid-base regulation and osmoregulation
Accountable to:

Weihrauch Lab (Crab Lab)

Responsible for University of Manitoba
Appointment: January or May 2022
Salary $21,000 (CAD)/year for 4 years

Location Winnipeg, Canada

  
Overview of the project(s):

The general topic of our lab is: Acid-Base Regulation and Osmoregulation in Aquatic Invertebrates. 
The Weihrauch lab (The Crab Lab) is seeking a highly motivated Ph.D. student to investigate mechanisms involved in osmoregulation, nitrogen excretion and acid-base regulation in aquatic invertebrate species. According to the student’s interest, this can also be investigated with the background of inevitable rising atmospheric PCO2 levels (Global Change).   

Several projects are possible. Potential study projects include:  

  • Exploring the role of aquaporins in osmoregulation, ammonia, and CO2 transport  
  • Physiological effects of heatwaves and nitrogen stress 
  • Characterization of novel acid-base related transporters and their role in invertebrates and fish 

Potential study organisms include but are not limited to Horseshoe crabs (living fossils); Northern crayfish, Dungeness crabs, and Lobsters (commercially relevant and tasty); Green shore crabs (highly invasive species); Daphnia magna (water quality indicator).  


Overview of the lab:

In my laboratory, we follow an integrative research approach, combining experiments on the living animal (e.g. metabolic rates, hemolymph parameters), transport physiological methods (perfused gills, Ussing chamber experiments, electrophysiology), molecular techniques (qPCR & functional expression of transporters in oocytes), and imaging techniques.  

Research stays in labs of collaborator (nationally and internationally) and/or marine filed stations (e.g. Bamfield Marine Science Centre) are encouraged.  Students will usually present their work on national (CSZ) and international (e.g. SEB, SICB) meetings. The candidate will join my socially active lab, currently composed of 3 Ph.D. and 3 MSc students (plus undergraduates). 

Requirements:

To be considered, an M.Sc. degree with a background in animal physiology is required. Knowledge of molecular and/or imaging methodology is an asset.  

Ideally, the candidate has a minimum score of 75 out of 100% (or equivalent) in order to apply successfully for additional internal and external funding. For international students a valid TOEFL-test (or equivalent) is required in addition to excellent communication and writing skills (English).

Requirements
Although landlocked, our Department entertains circulatory seawater systems for marine studies, as well as freshwater facilities. We are also equipped with temperature, light, and humidity adjustable environmental rooms, and a microscope suite 

Application Process 

If you are interested, please provide your updated CV, an unofficial transcript, a copy of MSc and BSc thesis, and contact information of at least 2 references.
