Dr. Andreazza is a Professor in the Departments of Pharmacology & Toxicology and Psychiatry and holds a holding Tier II Canada Research Chair in Molecular Pharmacology of Mood Disorders and the Thomas C. Zachos Chair in Mitochondrial Research. Dr. Andreazza received PhD in Biochemistry from the Federal University of Rio Grande do Sul, RS, Brazil. She has published over 150 research articles with an h-index factor of 45. She is the recipient of several prestigious research awards, including the 2018 Canada Top 40 Under 40 and has received funding from the Brain and Behavior Foundation (NARSAD), the Canadian Institutes for Health Research, the Ontario Mental Health Foundation and the Ontario Ministry of Research and Innovation. Her research focuses on the understanding of the role of redox modulations and mitochondrial dysfunction in mental illness, especially in mood disorders.
 
Dr. Andreazza's research focuses on the understanding of the role of mitochondrial function in mental illness, especially in mood disorders. As neurons depend on mitochondrial function, dysfunctional mitochondrial during neurodevelopment is expected to impact neurotransmission with potentially crucial implications for mood disorders. Currently, Dr. Andreazza is evaluating the impact of mitochondrial dysfunction on neurotransmission using 3D brain organoids generated from induced pluripotent stem cells from patients with bipolar disorder and/or mitochondrial disease. 
 
To accelerate the discovery of effective therapeutic approaches to treat mitochondrial dysfunction/disease, Dr. Andreazza founded the mitoNET.ca, which after successful fundraising and support from the University of Toronto became MITO2i.  The objective is to unite researchers from different medical fields with a common interest in unveiling the role of mitochondrial function and genetics in human diseases and transform mitochondrial health.
