Dr. Dayna Loyd Averitt, Ph.D.

DAveritt@twu.edu

Dr. Averitt is a neuroscientist interested in neural mechanisms of pain and analgesia. I use animal models of pain conditions, sensory neuron cultures, and human nerve endings to study molecular mechanisms in the peripheral nerves that may underlie why some pain disorders are more common in females than males. Dr. Averitt is also interested in studying brain circuitry involved in sex differences in pain and opioid analgesia and discovery of novel non-opioid pain therapeutics.

Key Words: neurosensory research, pain management, and sex differences in pain.

Dr. Patricia Bowyer

pbowyer@twu.edu

I am interested in examining the implications/outcomes of using a specific occupational therapy theoretical approach on the functional cognition of individuals receiving occupational therapy services. Humans are dynamic in that one aspect of living, being and doing cannot be viewed as a singular experience. Rather, the interaction between occupational therapists and the person, or population, receiving services has to account for the biological, psychological and emotional realm. The theory that I use to guide my research aims to aid in understanding the complexities of the interplay amongst these multiple aspects of being a human and implications once a disability or disease process has occurred. My research interests focus on assessment, intervention and program development using the theory as a guide to aid in practical application with individuals in a variety of contexts and with various diagnoses amongst which are individuals with cognitive impairments.

Key Words: functional cognition, theoretical implications linked to functional cognition, and patient outcomes and functional cognition.

Despite uncertainty surrounding the exact molecular cause of neurodegeneration, a common feature is the accumulation and aggregation of neuronal protein fragments resulting from an increase in their production, or a decrease in their removal. Previously we found that the N-end rule pathway of the ubi quitin-proteasome system is able to remove specific protein fragments associated Alzheimer’s disease, Parkinson’s disease, Amyotrophic lateral sclerosis and frontotemporal lobar degeneration. This exciting discovery suggests that defects in the N-end rule pathway may contribute to neurodegeneration. Our research uses genetically modified mice, yeast, and cultured cells to understand how aggregation-prone protein fragments cause toxicity to neurons and to identify cellular pathways that prevent neurodegeneration. 

Key Words: neurodegeneration, protein aggregation, and protein degradation.

Dr. Dowon Choi

dchoi2@twu.edu

My research agenda focuses on neurodevelopmental disorders, also known as neurodiversity depending on philosophical perspectives. I am particularly interested in ADHD, specific learning disorders such as dyslexia, and their interventions and assessments within dialectical frameworks. These frameworks, characterized by their pluralistic, comprehensive, and dynamic nature, offer a valuable alternative to traditional medical disease models. Dialectical models allow me to include other exceptional populations in my research, such as creative, gifted, and talented students.

Keywords: Neurocognitive funtioning (e.g., executive funtioning and metacognitive skills including mindfulness), creativity and ADHD, gifted or intellectually talented students.

My research interests surround Autism Spectrum Disorder (ASD) evidence-based screening and assessment strategies in primary care settings. I am a new faculty member with multiple publications related to ASD screening, detection and early intervention but I have not applied for external project funding yet. My doctoral mentor is Dr. Temple Grandin, one of the world’s most well-known individuals with ASD. I look forward to future interdisciplinary collaborations with Dr. Grandin and other TWU faculty whose research focus aligns with the Woodcock Institute’s mission.  

Key Words: Autism Spectrum Disorders. 

Dr. Wyona M. Freysteinson

wfreysteinson@twu.edu

My area of research is body image, and in particular mirror viewing after physical trauma (i.e. amputation). Qualitative studies with individuals who have had body disfigurement suffer from “mirror trauma. I theorize that viewing self in the mirror has a significant neurological component (frontal cortex). Briefly, there is a neurological "mirror memory". When the mirror image is altered, there is a disruption of the neural network. This disruption can be so severe that is leads to a sympathetic nervous system reaction and psychological trauma.

Key Words: neurocognitive, body image, and mirror viewing. 

Dr. Hui-Ting Goh

Key Words: post-stroke recovery, non-invasive brain stimulation, cognitive-motor interaction

Catherine Cooper Hay

chay1@twu.edu

I utilize a mixed methods approach to contribute to our understanding of motor and cognitive recovery following acquired brain injury. My research has included qualitative investigations, neurological interventions for upper extremity recovery, and observational studies with large datasets. I am especially interested in the outcomes of mild stroke and brain injury survivors and the development of effective, accessible, interventions to address cognitive impairment, depression and anxiety after stroke.

Key Words: utilizing large administrative datasets to assess stroke and brain injury outcomes, upper extremity motor recovery after neurological injury, and identifying and addressing cognitive impairment in mild stroke.

Dr. DiAnna Hynds

dhynds@twu.edu

The research in our laboratory is focused on molecular mechanisms of axon growth and guidance, fundamental processes for neurodevelopment or recovery after damage to the nervous system. This work interfaces with the mission of the Woodcock Institute as it addresses the mechanisms responsible for basic neuroplasticity, the basis behind cognition. In particular, we are interested in distribution of particular proteins (e.g. neurexin) that are involved in determining synapse identity. These proteins are dysregulated in developmental conditions, including autism spectrum disorders. Thus, we have a mechanistic connection to understanding neurocognition, its testing, and the neuroanatomical correlates of variation in cognition.

Key Words: neurodevelopment, neuroregeneration, autism spectrum disorders

Dr. Elif Isik

Self-management is a complex process, especially for children, that necessitates professional instruction and guidance. Pediatric and community health nurses can provide essential learning steps and continuity of care for children with chronic conditions such as asthma. I am planning a study for school-age children ages seven to 18 by developing and implementing web-based intervention sessions for asthma self-management. School-aged children are capable of learning how to manage their asthma through proper age-appropriate education and support.
