Position: Undergraduate Thesis Student

Biography:

Eliana is currently working towards her Bachelor’s degree in Psychology at McGill University, and is completing her second undergraduate honours thesis under the supervision of Dr. Brett Thombs. Before joining the DEPRESSD team, she worked as a summer student at the Ottawa Hospital Research Institute where she helped conduct a systematic review of behaviour-change techniques, and at the Hebrew University of Jerusalem where she took part in the development of an app to test stroke patients on their linguistic impairments. Her first thesis compared depression prevalence estimates based on a commonly used screening tool (HADS) versus a validated diagnostic interview (SCID). Her second thesis examines methods of optimal cutoff selection in depression screening studies. She is also working on a replication of a study that demonstrated the efficacy of anti-inflammatory drugs in reducing depressive symptoms.
