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 "Admission Information & Requirements" - "Prepare Application" - "Supervision" 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 pique 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.

Both acinar and ductal cells can give rise to PDAC in murine models. However, the gene expression profiles of these tumors, as well as their role in tumor heterogeneity remain unknown. The objective of this study was to understand whether the cellular origin of PDAC could cause functional or molecular heterogeneity. We created PDAC cell lines from mouse models (Sox9CreER;KrasLSL-G12D;Trp53f/f mice a.k.a. Duct:Kras-p53 mice and Ptf1aCreER;KrasLSL-G12D;Trp53f/f a.k.a. Acinar:Kras-p53 mice), which developed tumors originating from ductal or acinar cells, respectively. Duct:Kras-p53 mice formed high grade PanINs, developed PDAC much faster, and had a shorter lifespan compared to Acinar:Kras-p53 mice. In contrast, Acinar:Kras-p53 mice formed abundant of low grade PanINs with mucinous characteristics and PDAC initiation was delayed. I performed differential gene expression analysis between 12 acinar- and 13 ductal-cell-derived tumors using a specific R programming language package called DESeq2. I found 827 differentially expressed genes between tumors of different cellular origin (p-value
Pancreatic ductal adenocarcinoma (PDAC) is a deadly disease with a ductal morphology. Prior research has identified both pancreatic acinar and ductal cells as possible cells of origin for histologically similar PDAC. However, because different mutations were induced in acinar and ductal cells, apt comparisons could not be made to address whether the tumor cell of origin influences PDAC initiation, development, and other tumor differences. To address this open question, I induced oncogenic Ras expression (KrasG¹²D) with concomitant homozgyous Trp53 deletion at 4 weeks of age in a ductal cell specific (Sox9CreER; KrasLSL-G12D; Trp53flox/flox (“Duct:KPcKO”)) and an acinar cell specific (Ptf1aCreER; KrasLSL-G12D; Trp53flox/flox (“Acinar:KPcKO”)) mouse model. I found that Duct:KPcKO mice met their humane endpoints earlier (82 days post injection, p.i.) than the Acinar:KPcKO mice (128 days p.i.), for reasons associated with differences in the timing of PDAC onset. While tumors from both cells of origin were similarly proliferative and shared many physical characteristics, Duct:KPcKO mice developed tumors much earlier than Acinar:KPcKO mice and this was further associated with a difference in precursor lesion initiation. Specifically, ductal cells only formed high-grade lesions while acinar cells formed precursor lesions of all grades. These findings suggest that cell type intrinsic differences may allow ductal cells to rapidly form PDAC under genetically favorable conditions. In comparison, acinar cells likely require additional steps to alter cell identity and become duct-like – thus delaying PDAC initiation and extending survival. Taken together, I have demonstrated, by using cell type specific mouse models, that cell of origin can alter disease initiation, progression and impact PDAC phenotype.
