Research

I currently perform signal quality assessment for collaborators who are exploring physiological correlates of intervention effects observed in children and adolescents with autism. In the Computational Behavioral Science Lab, I lead the following projects.

HeartView: An extensible, open-source, and web-based signal quality assessment pipeline for ambulatory cardiovascular data

Wearable sensor systems allow electrocardiograph (ECG) data to be collected less obtrusively, especially from populations who may present with behavioral or attentional difficulties. However, given the ambulatory and high sampling frequencies of these systems, raw ECG data is often noisy and requires pre-processing that is typically time-consuming and non-standardized due to non-transparent reporting of closed-source pipelines. In this project, I am developing an open-source pipeline with an accompanying web-based dashboard that can perform signal quality assessment on ambulatory physiological data from ECG, photoplethysmograph (PPG), and electrodermal activity (EDA) devices.

A multimodal and multimethod assessment of dyadic biobehavioral synchrony in children with autism spectrum disorder

Dyadic synchrony is the temporal coordination of behavioral and physiological processes between two individuals. This coordination has important consequences for social and relational processes, which appear atypical in individuals with autism. Moreover, research on autism has seen a growing trend towards finding potential genetic, neurological, and physiological markers, with the rationale that biomarkers could better identify clinical subgroups and guide more personalized treatment planning.
I am interested in exploring how sociobehavioral and cardiac signals interact synchronously (or asynchronously) during dyadic interactions between children with autism and their caregivers.
