Research

My main research interests broadly encompass parent-child interactions: how to systematically observe joint engagement, identifying caregiver contributions, and the application of systematic observation measures across diverse cultures.  I am also interested in parental support systems for parents with children facing developmental difficulties, particularly in the context of and time surrounding early developmental disorder diagnosis.

Areas of Expertise

I am currently the master rater for the Joint Engagement Rating Inventory (JERI), a protocol for the systematic observation of dyadic interaction between a primary caregiver and a young child.  Through this role I have worked with projects around the world to apply applicable JERI items to measure joint engagement and other communicative behaviors.  I have also developed, along with the researchers on the projects, new items that fit within the JERI framework but measure project specific behaviors.  The the JERI has been used with typically developing infants aged 12 months to children with developmental and cognitive delays aged 10 years and older.  

Current Research

I have a number of current research lines:

1. Using maternal education as a measurement of support resources in an everchanging landscape of economic disparity. Specifically, I am interested in understanding unique contributions of maternal education to educational achievement and hope to investigate how mothers with some college or post-highschool schooling compare to those with less and more educational experience.

2. Neighborhood impact on African American and Latino youth. Specifically, understanding how neighborhood cultural alignment might support academic achievement.

3. Joint engagement as a predictor for later child language pragmatics and theory of mind understanding. This investigation is an extension of previous work with a longitudinal sample (12 months to 36 months) with cognitive process outcomes (at 48 months).

4. Application of JERI rating items to diverse populations. There are three veins within this current research. 1. Adapting JERI items to capture potential differences in how mothers and father interact with their toddlers. 2. Create new culturally relevant rating items to measure constructs unique to African American parenting interactions. 3. Continue working with the WHO to apply a corpus of rating items internationally to create global measures of joint engagement as outcomes for a caregiver intervention study.

Job Description

As Center Research Coordinator, I provide leadership and administrative support for multidisciplinary research initiatives at the Georgia Center for Developmental Science. This position coordinates research operations, facilitates collaboration among faculty, staff, students, and external partners, and ensures the successful implementation of center activities in support of developmental science research, education, and community engagement. My goal is to make sure that research operations run smoothly from conception to implementation to project closure by providing support at every stage of the research process and providing realtime training to individual project staff to further develop their own expertise in research production.
