Jennifer Bisson, Ph.D.   Lecturer, Clemson University 

Dr. Bisson received her Ph.D in Developmental Psychology and a Quantitative Research Methods Certification from the University of Connecticut in 2013. She is currently a Lecturer in the Department of Psychology at Clemson University. For her teaching effort, she has been awarded the University of Connecticut's Outstanding Teaching Award and the Dean's Award for Student Engagement from Clemson University.

Research Focus: 
Her research focuses on the etiologies, symptoms, and perceptions of autism spectrum disorder using theory and methods from social psychology, psychophysiology, cognitive science and neuroscience. Dr. Bisson also has expertise in multivariate statistics and advanced statistical techniques used to track change over time. Currently, her lab is exploring cross cultural differences in perceptions of autism spectrum disorder, factors that predict person first language in academic writing, and differences in object use in individuals with autism.

 

Jessica Bradshaw, Ph.D.   Lecturer, University of South Carolina

Dr. Bradshaw received her PhD in Clinical, Counseling, and School Psychology from the University of California, Santa Barbara after which time she completed her postdoctoral work at the Marcus Autism Center, Emory University School of Medicine. She has been involved in autism research since her undergraduate work in Cognitive Science at the University of California, San Diego and her post-baccalaureate work at the Yale Child Study Center.

Research Focus: 
Dr. Bradshaw’s research focuses on early identification and intervention of autism spectrum disorder (ASD) in the first years of life. Specifically, she is interested in: 1) quantifying the emergence of, and interrelations between, social behavior, visual attention, and motor skills in neonates, infants, and toddlers, 2) identifying aberrant neurodevelopmental pathways that lead to the emergence of autism spectrum disorder (ASD), and 3) translating these basic findings to early detection and intervention strategies for ASD. She uses behavioral, eye tracking, and physiological methods to map early neurobehavioral development and identify pivotal transitions that occur between birth and 12 months of age, with a particular interest in birth through 5 months. In the context of longitudinal research designs with infants at risk for ASD, she aims to understand how disruption during these early developmental periods may have cascading consequences on the development of social communication.

Norma Frizell, Ph.D.   Assistant Professor, Dept. of Pharmacology, Physiology & Neuroscience, University of South Carolina School of Medicine

Dr. Frizell of the Pharmacology, Physiology & Neuroscience lab at USC School of Medicine received her postdoctoral training at the University of Ulsters, N. Ireland and the University of South Carolina.  She received her Ph.D. from The Queens University of Belfast, N. Ireland.

Dr. Poulain is originally from France and obtained her Ph.D. from the University Paris 6-Pierre et Marie Curie, studying the roles of microtubule-regulating protein stathmins in neuronal morphogenesis. She became convinced that observing axon growth directly in the embryo in vivo would provide invaluable insights on how axons integrate different signals from the environment to navigate properly. She joined the laboratories of Drs. Chi-Bin Chien and Joseph Yost at the University of Utah to study the roles of Heparan sulfate proteoglycans in axon guidance in vivo in zebrafish.  

Research Focus: 
Their research aims to understand the cellular and molecular mechanisms by which axon pathfinding and selective degeneration lead  to the formation of functional brain circuits. They are also developing new models to investigate the contribution of axon degeneration to neurodegenerative disorders such as Alzheimer's disease. They use zebrafish as a vertebrate model system and a unique combination of genetic, embryological and live imaging approaches to observe and manipulate axons  directly in the embryo in vivo.

Jill Turner, Ph.D.   Assistant Professor, South Carolina College of Pharmacy 

Dr. Turner received her Doctor in Philsophy, Neuroscience from Georgetown University in 2007.  

Research Focus: 
Her research aims to understand the biology underlying the low success rates of smoking quitters. She investigates the genomic alterations resulting from chronic nicotine administration and withdrawal.  In addition to learning about genomic mechanisms, she is also interested in how she could apply this knowledge to further personalize medicine.

Jeff Twiss, M.D., Ph.D.   SmartState Chair in Childhood Neurotherapeutics, Department of Biology, University of South Carolina 

Dr. Jeff Twiss received his M.D. from the Medical University of South Carolina (MUSC) in 1990 and his Ph.D. in Molecular and Cell Biology from MUSC in 1992.  He completed his Post-doctoral training in Neurobiology at Stanford University.

Research Focus:
Dr. Twiss' research focuses on neural repair mechanisms and how to utilize these mechanisms to improve recovery after injury. Long range communication is provided through the axonal processes. These processes in adults and large mammals can extend up to meters and if they are disrupted, either through injury or disease, often lead to permenant loss of function, unless neural connections can be restored. The neural processes the he studies are also impactful to neural function, synaptic plasticity, and development. The SmartStart Childhood Neurotherapeutics at the University of South Carolina focuses broadly on the molecular mechanisms of nervous system diseases with ultimate goals of finding novel strategies to treat disease and encourage neural repair.
