Research Interests


Jacqueline Blundell

My research interests lie in understanding the behavioral and neuroplastic changes that are involved in affective and cognitive disorders. Overall, my goal is to make a significant contribution in understanding and advancing the treatment of neuropsychiatric illness.

Using a multi-disciplined approach that combines both behavioral and molecular techniques, my research plan involves two specific aims. First, I will characterize the phenotypic and molecular changes in adult cognitive-, social-, anxiety-, and depression-related behaviors that result from traumatic stress. Second, I will characterize the phenotypic and neuroplastic changes that result from environmental insult during the early stages of development. Also, I will identify specific biological risk factors that are altered by early environmental insult which in turn, increase the likelihood of developing neuropsychiatric illness after exposure to a traumatic stressor. In all, I hope that my research will lead to an increased understanding of the causes of neuropsychiatric disorders that will ultimately result in the development of novel treatments.


I received my Ph.D. in Behavioral Neuroscience from the Memorial University under the supervision of Robert Adamec. Upon completion of my Ph.D. I completed a Post-doctoral Fellowship at the University of Texas Southwestern Medical Center.

Student Mentoring

Undergraduate: I look forward to the opportunity to supervise Honours projects. Students who are interested in animal models of anxiety and depression, should contact me to set up an appointment. Students will receive hands-on experience in all aspects of study design, data collection, data analysis and presentation of research results.

In addition to honours students I am interested in mentoring other psychology undergraduate students who would like to gain some research experience by volunteering in a psychology laboratory. I have found that undergraduates that volunteer in psychology labs find it to be a very rewarding experience.

Graduate: I am currently recruiting graduate students who are interested in conducting research into the temporal behavioral and molecular changes that occur following traumatic stress. If your academic research interests are in line with those discussed above, you are encouraged to contact me to discuss the possibility of graduate work in my lab.
