Research

The increasingly pervasive impact of stress in our day-to-day lives has served as a catalyst for the growing prevalence of affective disorders in today’s society. Consequently, understanding the neurobiological underpinnings of stress and the mechanisms by which these factors influence the brain and behavior is of the utmost importance. My research to date has focused on elucidating the neuroanatomical framework that mediates stress coping, emotionality, and goal-directed behavior, and how exposure to environmental factors (i.e., chronic stress, drugs of abuse) can produce long-lasting neurobiological adaptations that contribute to disruptions in homeostasis and the emergence of negative affective states. This is the foundation of my research program as a tenure-track Assistant Professor in the Department of Integrative Physiology and Neuroscience at Washington State University (WSU).

Current Funding

Establishing behavioral and biological predictors of problematic cannabis use
Role: PI, 10% effort
Type: ADARP DMAC Pilot Grant (137452)                                                   Funding period: 10/2019-12/2020
Goals: The purpose of this grant is to conduct comprehensive behavioral phenotyping of male and female rats to gain insight into factors associated with high vs. low rates of cannabis vapor self-administration.
 
Chronic cannabis-induced alterations in stress reactivity
Role: PI, 10% effort                                                                                        
Type: ADARP Pilot Grant (136020)                                                               Funding period: 07/2019-12/2020
Goals: This project follows up our previous DMAC-funded research by exploring whether blunted stress reactivity is a cause or a consequence of chronic cannabis exposure.
 
Drug context-induced instrumental cocaine seeking: Influence of memory reconsolidation
Role: Co-I (PI, R. Fuchs), 5% effort                                                   
Type: NIDA 2 R01 DA025646-07                                                                   Funding period: 01/2010-06/2022
Goals: This project aims to identify relay brain regions that permit interaction between the basolateral amygdala and dorsal hippocampus in early-phase cocaine memory reconsolidation.

Effects of developmental cannabis exposure on prefrontocortical structure and function
Role: PI, 40% effort                                                                                        
Type: NIDA 1 R21 DA043722-01A1                                                              Funding period: 09/2017-08/2019 (Currently in No-Cost Extension)
Goals: This project examines the effects of adolescent- vs. adult-onset cannabis vapor self-administration on prefrontocortical structure (cell morphology and white matter development) and function (attentional set-shifting and effort-based decision making) in male and female rats.
