I am using zebrafish (Danio rerio) as a model organism in two projects. The first involves the CYP1 family of enzymes, examining their substrate specificities with high-throughput screening (McMaster HTS webpage). The second project is testing the potential for additive toxicity between priority contaminants and their underlying mechanisms of action.  Most recently, I am performing studies to examine the interaction between temperature and chemicals as independent stressors.

Not only do I enjoy my time in the lab, but getting to and from work on my bike is usually an adventure as well. “Get a bicycle. You will not regret it, if you live.” -Mark Twain

Shamaila Fraz, Post-doctoral researcher

Educational background:

  • BSc, MSc in Pharmacy, Punjab University, Pakistan
  • MSc in Ecotoxicology, University of Göteborg, Sweden
  • PhD in Biology, McMaster University, Canada

I am interested in studying the toxicity of chemicals and other environmental stressors like temperature. I love working zebrafish for their suitability to ask basic research questions.  At present, I have been optimizing conditions for culture of yellow perch embryos in lab, and alongside I have been studying the effects of non-optimal incubation temperature regimes during early development of yellow perch. I am conducting studies to examine the endpoints like normal morphological growth, development and yolk utilization rates and behaviors. 

In addition to love working in the lab, I love to spend time in nature!

Andrea Michelle Murillo Ramos, Ph.D. Candidate

Educational Background:

  • B.Sc. in Biology, University of Florida 
  • M.Sc.in Biology, University of Regina 

I am a marine biologist that is currently investigating the role of estradiol signaling in the polychaete, Capitella teleta. Outside of vertebrates, we know very little about the role of estrogen receptors in protosotomes. C. teleta has an estrogen receptor that is activated by estrogens at low concentrations. The goal of my thesis is to investigate different aspects of the estrogen signaling pathway in these amazing polychaetes. 

Besides doing science, I enjoy being really bad at trivia competitions.  

 

 

 

Shemar Williams, MSc Candidate

Educational Background:

  • BA in General Biology, Wilfrid Laurier University

Metformin is the most common first line oral therapeutic agent used in the treatment of type-2 diabetes. Due to its widespread use, metformin and its bacterial breakdown product, guanylurea, have been increasingly detected in freshwater systems. Metformin exposure in adult fish has shown impairments in behavior and reproductive activity however the literature concerning their effects in embryo and larval fish is scant. My thesis focuses on how these compounds impact certain developmental parameters (I.e., morphology, swim behaviour, and oxygen consumption) in embryo and larval zebrafish.

Research Leave is where?

Posted on by

Research leave has rolled around and again, it seems to follow family catastrophe.  I *thought* we would be in Bergen, Norway right now but new elder care duties seriously cancelled that plan. So now I am local.  Research Leave in Hamilton!!!  At the end, it looks like COVID might have cancelled things anyways because I am not sure relocating in the middle of the largest wave of the pandemic would have been so attractive.  Still, it was Norway and I am missing the sea.

My priority for research leave has always been to do something significant for my research program.  For my first, I spent 13 months in Sweden and this was where I fist started doing behavioural research with fish.  I also learned to experiment with primary hepatocytes, although this hasn’t been incorporated in my lab in the same way.  That is mostly because the results of the experiments were a bit blah and unexciting for the compounds we were testing in hepatocyte culture.  But the behavioural research is a different story.  Now we have added in a suite of behavioural assays in different life stages.  For juvenile and adults, we have used courtship, aggression, behavioural choice experiments with odorants and thermal preference tests. For larval fish, we now do a whole range of swimming (general swimming, light:dark response, thigmotaxis), startle responses and feeding behaviour.  My year away pushed us in a new direction that has been rewarding.

So what is on the table this year?  Planning is still an active process but one thing is for sure is that I have some training and planning to do. First, is training to work with human subjects as we have some projects that will cross into social sciences.  The other major training need is to brush up on transcriptomics analyses and R so that we are better equipped for some of the new data we will be generating in the next few years.  Second, is planning for both the lab and field for our perch embryo experiments. We learned so much from last year’s experiments and have to adjust. We will adjust the lab for better rearing protocols and really minimize some of the labour issues we encountered last year. We are adding  new lights to help with feed training the larval fish too. We are also adjusting our field sites and I need to get new permits in place. This is really exciting and I already have new Windermere traps under construction with the engineering lab.  I can’t wait for perch spawning.
