Curriculum Vitae

My research aims to advance knowledge about how the infant brain develops to support healthy child development. I am particularly interested in early environmental and neurobehavioral factors that shape this development, especially those occurring within the first two years of life. Outlining details about the neurodevelopmental patterns subserving healthy child development is not only critical for understanding processes of normative development, but is also necessary for elucidating deviant patterns of neurodevelopment foundational to the emergence of intellectual, behavioral, and psychiatric disorders. My work utilizes a multi-modal panel of neural, behavioral, and biospecimen markers to gain a holistic view of human brain development.

Melissa Jenkins, PhD

Curriculum Vitae

My program of research focuses on risk factors for violence and exploitation among individuals with intellectual and developmental disabilities (IDD), as well as the role of adverse childhood experiences in physical and behavioral health outcomes among individuals with IDD. My research approach is guided by the following beliefs: (a) research is impactful when the population(s) of interest perceive it as as both important and relevant; and (b) a crucial component of effective research is the active participation of community members. My goal is to develop comprehensive interpersonal violence prevention programming that balances safety and empowerment through consistent community engagement and partnership.

Libby Hladik, OTR/L

Curriculum Vitae

My research promotes child and family health and well-being through engagement in meaningful occupations with children with autism and sensory processing disorders, adolescents and young adults with intellectual disabilities, and infants as risk of developmental disorders.  I work from my foundation in Occupational Therapy and Occupational Science with a particular interest in community engagement and family-centered interventions. My research uses a stakeholder engaged approach and often includes components of community based participatory research (CBPR). My current projects include:

  • Research engagement on health research priorities for people with intellectual disability
  • Evaluation of accessibility for cultural institutions for families with children with autism
  • Qualitative investigation of mother’s experiences of parent-mediated feeding therapy for children with autism and feeding challenges
  • A program evaluation for alternative education for pregnant and parenting teens in high school

In addition to research, I have a strong interest in interdisciplinary clinician training with a focus on justice, equity, diversity and inclusion.

Emma Libersky

Curriculum Vitae

I study language acquisition in bilingual children born preterm. I am interested in the role of parent input in successful language outcomes, as well as the role of domain general cognitive processes in word learning. In another line of work, I investigate the impact of speech disfluencies on word learning across the lifespan, in populations born full term. I’m interested in how bilinguals and monolinguals are impacted by disfluencies produced in native and non-native accents, and how disfluencies pattern with other features of spontaneous speech, like codeswitches.

Helen Long, PhD, CCC-SLP

Curriculum Vitae

My programmatic line of research seeks to identify early predictors of speech impairment severity in cerebral palsy (CP) through the study of infant vocal behaviors. This work is informed by an infrastructural framework of vocal development which presumes that earlier developmental stages of vocal production are foundational to more advanced stages and eventual speech production. My research is richly grounded in my experience as a school-based speech-language pathologist where I primarily served children with CP and other neurodevelopmental disorders with severe communication impairments. My long-term goal is to facilitate earlier diagnosis and clinical treatment planning to improve outcomes in children with complex communication needs as young as infancy.

Olivia Pokoski, MPH

Curriculum Vitae

My research interests include the intersection of developmental disabilities, health disparities, and maternal and child health. Currently, under the Study to Explore Early Development (SEED), I am working to understand how the COVID-19 pandemic has influenced the adaptive behavior among preschool aged children with autism spectrum disorder (ASD). Understanding the mechanisms through which the pandemic may have influenced specific areas of development in children with ASD will allow us to better deliver services during unprecedented times in the future. Additionally, I am working on estimating the statewide prevalence of children with ASD in Wisconsin using Medicaid claims and educational data. Future work involves the inclusion of biomedical informatics to create an ASD registry for the state of Wisconsin to gain a better understanding of the epidemiology of ASD.

Emily Schworer, PhD

Curriculum Vitae

My research centers on cognitive and adaptive functioning development in individuals with Down syndrome throughout the lifespan. One goal of this work is to determine how biological and environmental factors alter development and explain heterogeneity in these skills across individuals with Down syndrome; this information is important for directing interventions and individualized treatment plans. Another important aspect of studying cognition in individuals with neurodevelopmental disabilities is measurement. My work is aimed at establishing feasible, reliable, and valid cognitive outcome measures for research studies and future clinical trials involving individuals with Down syndrome. This includes identifying cognitive measures that correlate with biomarkers of brain pathology in the unfolding of Alzheimer’s disease in Down syndrome. I am also interested in developing remote procedures for cognitive measurement to reduce participant burden and improve access to research in rural communities.
