Thesis Research as a Genetic Counseling Student

Kyle Mahoney, M'23, presents his thesis research at the Perelman School of Medicine's Master's Students Research Symposium.

 

As a requirement of graduation, every student in the program completes an individual research project.  Writing a master's thesis is a major accomplishment and a daunting task. That's why the program is structured to guide students through the process. Projects are selected by students based on their interests, and topics are finalized and clarified during the first semester.  Students refine their proposals as they complete literature reviews and develop their IRB submissions during a course in research design in the spring semester of the first year. 

 

Throughout the summer and second year, students collect and analyze data, and write their thesis manuscripts, all under the supervision of their primary mentors: one who is a member of the program leadership and one who is an expert in the field of study, typically a genetic counselor or UPenn faculty member.

Research projects range from professional surveys and chart reviews to qualitative studies of small populations of patients with rare diseases, again depending on student interest.  Small grants are available through the program to support the research.  Students are also encouraged to apply for funds available through NSGC SIGs and other organizations, and many have received research funding.

The majority of students successfully submit abstracts to local and national conferences and for publication toward the end or soon after their second year in the program. A number of 2025 graduates have manuscripts in review, with more in the final stages of submission to a journal, and two already published.

Having gained experience in all aspects of the research process, students graduate from the program with the capacity to develop a research idea, to conduct ethical research, to interact with an IRB, to convert raw data to a written and comprehensible document, and to work collaboratively on a professional project.
