Giovanni’s main interests lie in the elucidation of the neurobiological circuit underlying decision-making.

He graduated from Universidad Católica Andrés Bello (Caracas, Venezuela) with a B.S in Psychology in 1997 and then did two master’s degrees, one in Organizational Psychology and another in Behavior Analysis. He received his Ph.D. from Concordia University under the direction of Prof. Peter Shizgal; his graduate research focused on the role of dopamine in decision-making.  During his postdoctoral studies at the University of Maryland under the advice of Joseph Cheer, he studied how modulation of the dopaminergic system by the endocannabinoid system alters goal-directed behavior. At the Université de Montreal, under the advice of Pierre-Paul Rompré and Daniel Levesque, Giovanni identified an NMDA receptor (GluN2C) responsible for the relay of the reward signal in the ventral tegmental area.  He is now studying the development of dopamine neurons during adolescence and the effect of early-life exposure to cannabinoids. He has extensive experience using in-vivo techniques (Fast-scan cyclic voltammetry, electrophysiology, microdialysis, fiber photometry, optogenetics) to correlate behavioral outputs with brain circuitry.

I'm broadly interested in the molecular and neural circuitry basis of behaviors. Currently, I'm involved in projects that study the structural and functional changes of the dopamine system due to adolescent amphetamine exposure. After my gap year, I plan to further my scientific training by pursuing a PhD in neuroscience.

One of my research interests focuses on understanding whether and how exposure to different drugs during adolescence affect ongoing brain development. During the first years of my graduate studies, I investigated the effects of different doses of amphetamine during adolescence, and how this exposure impacts: (1) behaviors that depend on proper prefrontal cortex functioning, and (2) the expression of genes that coordinate adolescent neurodevelopment and synaptic plasticity. 

After I fast-tracked into the PhD program, we started a collaboration with Dr. Patricia Pelufo Silveira to translate our studies in rodent models to humans, trying to bring together perspectives from developmental neurobiology and systems genetics. I use a wide range of bioinformatics methods to study the relationship between variations in expression of gene networks and mesocorticolimbic dopamine development.

I am interested in studying how drugs of abuse affect adolescent brain development. I am currently exploring sex differences in the effects of amphetamine on prefrontal cortex maturation and the role that the Netrin-1/DCC guidance cue system plays in this regard. Currently I am investigating whether manipulating the expression of this guidance cue pathway in selective limbic brain regions could induce protection against drug-induced developmental disruption.  I hope that this research will highlight the importance to consider sex as a biological variable when studying adolescent exposure to drugs of abuse.

After birth, the brain is a much more dynamic and vulnerable organ than many make it seem. Long distance dopaminergic axonal migration to the prefrontal cortex is still occurring in the adolescent brain. I want to understand how experiences in adolescence, particularly stress or exposure to drugs of abuse, impact dopamine axonal growth and adult cognitive and reward processing. My research project is focused on the role of axonal guidance cues and their cognate receptors and involves the combination of behavioral testing and calcium imaging methods in male and female mice.

The focus of my current research is to expand on our current knowledge of cannabis-induced psychosis. Specifically, the aim of this research is to investigate the impact of THC exposure during adolescence and how that impacts neuroinflammatory processes in mice and

in interaction with genetic biomarkers. More precisely, investigating if and how THC affects brain development andcognitive function via microRNA regulation of gene expression. If I am not in thelab I’m cooking and eating, or on a mountain (also eating).
