Relevant Degree Programs
Complete these steps before you reach out to a faculty member!
- Familiarize yourself with program requirements. You want to learn as much as possible from the information available to you before you reach out to a faculty member. Be sure to visit the graduate degree program listing and program-specific websites.
- Check whether the program requires you to seek commitment from a supervisor prior to submitting an application. For some programs this is an essential step while others match successful applicants with faculty members within the first year of study. This is either indicated in the program profile under "Requirements" or on the program website.
- Identify specific faculty members who are conducting research in your specific area of interest.
- Establish that your research interests align with the faculty member’s research interests.
- Read up on the faculty members in the program and the research being conducted in the department.
- Familiarize yourself with their work, read their recent publications and past theses/dissertations that they supervised. Be certain that their research is indeed what you are hoping to study.
- Compose an error-free and grammatically correct email addressed to your specifically targeted faculty member, and remember to use their correct titles.
- Do not send non-specific, mass emails to everyone in the department hoping for a match.
- Address the faculty members by name. Your contact should be genuine rather than generic.
- Include a brief outline of your academic background, why you are interested in working with the faculty member, and what experience you could bring to the department. The supervision enquiry form guides you with targeted questions. Ensure to craft compelling answers to these questions.
- Highlight your achievements and why you are a top student. Faculty members receive dozens of requests from prospective students and you may have less than 30 seconds to peek someone’s interest.
- Demonstrate that you are familiar with their research:
- Convey the specific ways you are a good fit for the program.
- Convey the specific ways the program/lab/faculty member is a good fit for the research you are interested in/already conducting.
- Be enthusiastic, but don’t overdo it.
G+PS regularly provides virtual sessions that focus on admission requirements and procedures and tips how to improve your application.
Epigenetics refers to the molecular events controlling gene expression that are independent of changes in the underlying DNA sequence. These events include DNA methylation, covalent histone modifications, and non-coding RNA-related mechanisms. Epigenetic modifications of DNA, namely DNA methylation, have been shown to contribute to the etiology of chronic diseases with cancer at the forefront. DNA methylation is dynamic and serves as an adaptive mechanism to a wide variety of environmental factors including diet.
My laboratory is focused on addressing the following scientific questions:
1) Do dietary bioactive compounds act through epigenetic mechanisms to prevent cancer and exert beneficial effects in adjuvant therapy?
Our hypothesis is that dietary polyphenols (e.g., resveratrol, pterostilbene, piceatannol, and coffee polyphenols) impact DNA methylation patterns and thereby gene transcription via modulation of expression and activity of epigenetic enzymes such as TETs and DNMTs. Changes in these enzymes, alter the occupancy of specific protein complexes in gene regulatory regions which determines chromatin structure and as a result gene transcription. Through this mode of action, polyphenols reverse cancer-specific patterns of DNA methylation; they lead to the activation of methylation-silenced tumour suppressor genes and concomitant suppression of demethylation-activated oncogenes and prometastatic genes. We are also exploring if epigenetic mechanisms regulated by polyphenols can sensitize cancer cells to traditional anti-cancer therapeutics.
2) Do dietary bioactive compounds reverse epigenetic aberrations underlying initiation of inflammation and inflammation-driven cancer?
Existing evidence suggests that at sites of inflammation the release of reactive oxygen species causes DNA damage that induces re-localization of epigenetic proteins and results in DNA methylation changes of associated genes during tumorigenesis. We hypothesize that bioactive compounds can prevent cancer development by targeting those changes in the DNA methylation patterns.
3) Do changes in epigenetic marks reflect dietary exposure to bioactive compounds?
We hypothesize that exposure to dietary polyphenols may leave stable marks in human body by inducing changes in DNA methylation patterns. Such molecular markers in easily accessible specimens are needed and should reflect long-term exposures. This will deliver quantitative tools for measuring the intake of bioactive food components in clinical and epidemiological studies.
1) Epigenetic regulation of the NOTCH oncogenic pathway in response to polyphenols from blueberries and grapes (stilbenoids: pterostilbene, piceatannol, resveratrol).
2) Epigenetic mechanisms of polyphenols in prevention of inflammation in a mouse model of colitis and colon cancer.
3) Epigenetic biomarkers of exposure to dietary bioactive compounds.
