Sharing our research activities with colleagues at CAVEPM.

Earlier in the spring, the Canadian Veterinary Epidemiology community gathered in Saint-Hyacinthe, QC for the annual conference of the Canadian Association for Veterinary Epidemiology and Preventive Medicine (CAVEPM). This year our group contributed five oral presentations (Wendy Xie, Elissa Giang, Roksolona Hovdey, Salah Uddin Kahn, Dylan Melmer). We also learned about navigating our way through information overload in the era of big data.

PhD student  - Equine Network Epidemiology and Biosecurity (ENEBT)  Team 

The Mathematical Epidemiology Laboratory, University of Guelph

Application Deadline: June 30, 2019

 Applications are invited for a PhD position in veterinary epidemiology and mathematical modeling in the Mathematical Epidemiology Laboratory ( at the Ontario Veterinary College, University of Guelph. The successful applicant will be involved in a research program that will apply quantitative methods to the area of equine infection control and biosecurity. The project will be co-supervised by Dr. Amy Greer and Dr. Terri O’Sullivan who co-lead the ENEB team at the Ontario Veterinary College. 


Applicants should have significant experience in veterinary medicine, epidemiology, and/or population health. The successful candidate will have excellent English language communication skills (both verbal and written), strong analytical skills, and experience conducting research in a highly interdisciplinary environment. Prior experience with R and working with horses and/or horse owners would be considered an asset. Preference will be given to applicants who also hold a DVM degree and who have experience working with veterinary professionals in a research environment. 

The starting date is September 2019 (contingent on funding), or as soon as possible thereafter.All qualified candidates are encouraged to apply; however, Canadians and permanent residents will be given priority. Review of applications will begin immediately and continue until the position is filled. Incomplete applications will not be considered and only selected applicants will be contacted for an interview.

 How to apply:

Applicants should first review the Graduate Studies website to ensure that they meet the requirements for admission to our graduate program (  Applicants must submit a cover letter that specifically addresses the applicants interest in equine epidemiology and biosecurity, a recent curriculum vitae, and a copy of their academic transcript (unofficial is fine). Applicants should also submit contact information for at least two individuals who can provide letters of recommendation to Dr. Amy Greer.


Nous sommes au Québec cette semaine!

Here we are in lovely Sainte-Hyacinthe, QC for the 2019 Conference of the Canadian Association of Veterinary Epidemiology and Preventive Medicine (CAVEPM).  We are learning about navigating science information overload in the era of big data. We are also presenting some of the work being done by our very own mathepilab members!

Elissa is going to Switzerland!

Congratulations to mathepilab member Elissa Giang for winning a Food from Thought Travel Award! Elissa will use the award to attend the 17th International Conference on Production Diseases in Farm Animals in Bern, Switzerland, where she will give an oral presentation of her research findings and promote knowledge mobilization for the Food from Thought research program. Elissa’s MSc work focuses on production-limiting diseases in swine (Streptococcus suis disease) and the use of mathematical models to simulate management-driven control strategies for reducing disease burden in the nursery. In light of recent changes made by Health Canada regarding the provision of medically important antibiotics in animals, the model will help to enable producers to consider management-driven interventions as alternative forms of disease control while also minimizing the use of antimicrobials. Well done Elissa!


Fall is the most wonderful time of year!

With fall comes the start (continuation?) of the academic travel season. Are you wondering where you might find members of the math.epi.lab this fall? We will be presenting our most recent research findings in Canada, the US, and Thailand so we will be "in transit" quite a bit this fall. Be sure to catch up with us if you are planning to attend any of the following conferences and events.

1) 2018 Calgary International Equine Symposium (Sept 2018)

2) Pandemic Influenza Outbreak Research Modelling (Pan-Inform) meeting (Oct 2018)

3) 15th International Symposium of Veterinary Epidemiology and Economics: ISVEE15 (Nov 2018)

4) Conference for Research Workers in Animal Diseases (Dec 2018)

New paper out from Luz Kisiel on dog population control

Congratulations to Luz and team on the publication of her second MSc thesis research paper. This is a great example of how models can be used to model dog population dynamics and then use the model to look at different surgical and non-surgical population control interventions. Spoiler alert: if you are running a surgical dog population control program and have limited resources the model suggests that changing your focus to young, female dogs exclusively is more effective in the long run than focusing on mixed groups of dogs.

2017 AAAS Golden Goose Award for Dr. Joyce Longcore

This morning I arrived at the office to an email from my doctoral supervisor Dr. Jim Collins at Arizona State University (ASU). The email had been sent to a long list of current and past collaborators of the lab all of whom have worked on or are currently working on research questions related to amphibian decline. The email was to inform us that last night in Washington, Dr. Joyce Longcore, Elaine Lamirande, Dr. Don Nichols and Dr. Allan Pessier, were awarded the 2017 AAAS Golden Goose Award. The award celebrates scientific success stories and Dr. Longcore and the other awardees are the perfect example of a great team doing some wonderful investigative work. 

Jim's email was also a reminder to me of how fortunate I was to complete my graduate training at ASU being mentored by Jim. As a member of his team, I also had the ability to interact with a large network of scientists, and graduate students from across the country that were all a part of a large, NSF funded Integrated Research Challenges in Environmental Biology (IRCEB) project focused on amphibian decline (Dr. Longcore was one of those scientists). It serves as an important reminder to me how experiences, conversations, and being treated as a colleague even when you are a graduate student can really shape the experience of graduate students. I have very fond memories of my time at ASU and the wonderful training environment in which I was "raised". Jim Collins, Elizabeth Davidson and the rest of the IRCEB team were all a huge part of that and seeing Dr. Longcore receive such a prestigious award in recognition of her work in the area of amphibian decline was a really wonderful surprise for a Thursday morning.
