Research Interests

Numerous developmental factors collectively contribute to a child’s development and their subsequent ability to successfully function and interact with their environment. Among others, developmental outcomes include cognitive functioning (which contributes to a child’s abilities for learning and success in school), capacity for social interaction, and capacity for physical interaction with their environment. The developmental factors contributing to a child’s development are numerous and span a vast variety of disciplines. Jeanette’s research interests lie centered around the effects and interactions of gender, genotype, stress, birth and early life trauma, premature birth, and social/familial interactions on the developmental outcomes of children.

Gender Differences in the Effect of COMT Genotype on Cognitive Functions that Depend on the Frontal Lobe

Jeanette is currently working a project examining how gender and genotype might interact with respect to an individual’s ability to perform a specific set of cognitive functions, called executive functions.

“Executive functions” refers to a cluster of cognitive skills dependent upon the prefrontal cortex. It includes

A) “ Working memory”: Holding information in mind and being able to mentally work with it, such as relating one idea to another or doing mental arithmetic.

B) “ Inhibition, effortful- or self-control”: Being able to resist a strong inclination to do one thing and instead do what is correct or required, such as not giving in to your first impulse when a more considered response is required.

C) “ Cognitive flexibility”: The ability to flexibly adjust to changed demands, changed priorities, or new challenges in order to complete some goal-directed action.

These cognitive control skills are thought to be the building blocks for many higher-order skills such as planning, problem solving, concept formation, and self-monitoring that are critical for cognitive and social development, and for success in school and in life.

Performance on executive function tasks is affected by prefrontal cortex dopamine levels. Clearance of dopamine in prefrontal cortex is critically dependent upon the deactivation of dopamine by the catechol-O-methyltransferase (COMT) enzyme.

Based on results found previously by Diamond and Colleagues (2004), the purpose of this study is to investigate further whether gender and menstrual cycle phase might interact with the effects of COMT genotype on the performance of executive function tasks.

Jeanette has always had a passion for investing in the lives of children. She is heavily involved with children who face a variety of challenges, such as volunteering with children who have Spina Bifida. She also has a particular passion for sports. Jeanette has enjoyed ski racing, as well as coaching alpine skiing, and played on competitive soccer teams for most of her life. Jeanette also enjoys other sports including surfing, skim boarding, windsurfing, and backpacking/hiking. She also has interests in food and wine, and is pursuing her level 2 sommelier certificate.
