Shannon Hoffman, PT, DPT

Shannon HoffmanShannon Hoffman, PT, DPT, joined the Attention, Impulsivity, and Regulation Lab as a project manager for the MINT (Mapping Impulsivity's Neurodevelopmental Trajectory) and VRAM (Virtual Reality Attention Management) studies, as well as the DelTA (Delay Tolerance Application) study. Shannon is a licensed physical therapist with over 10 years of experience working in both the clinical and research settings. She has worked with patients of all ages with a wide variety of neurologic and orthopedic diagnoses, and has taught several graduate courses in physical therapy. Shannon's interest in studying cognition, behavior, and emotion stems from her work as a physical therapist and a physical therapy instructor, where quality and/or quantity of movement frequently interacted with these psychological constructs. Shannon graduated from the University of Notre Dame with a Bachelor of Arts in Anthropology and Pre-professional studies. She earned her Doctor of Physical Therapy degree from Washington University School of Medicine in St. Louis.

Agnieszka Mlodnicka, Ph.D.

Agnieszka MlodnickaAgnieszka Mlodnicka, Ph.D., received Bachelor’s degrees in Psychology and Biology and minor in Chemistry from Texas A&M University. She received research training as a research assistant in Molecular and Human Genetics at Baylor College of Medicine. Agnieszka received her Ph.D. in Clinical Psychology with an emphasis in Neuropsychology from City University of New York-Graduate Center. Her clinical neuropsychological training included externships at Mount Sinai Center for Cognitive Health, New York University Child Study Center, and Memorial Sloan Kettering Cancer Center. She completed a yearlong internship at Wake Forest School of Medicine with training in pediatric neuropsychology, pediatric psychology, and child and adolescent behavioral inpatient therapy. Her dissertation research explored the impact of neurodevelopmental genes and environmental risk factors on the trajectory of hyperactive and inattentive symptoms from early preschool age to early adolescence. She is currently a Post-Doctoral Fellow at UC Davis MIND Institute, where she is responsible for assessments and research associated with the Mapping Impulsivity's Neurodevelopmental Trajectory (MINT) study in the Attention, Impulsivity, and Regulation (AIR) Laboratory, and Revisit Childhood Autism Risks from Genetics and Environment (ReCHARGE)/ Environmental Influences of Children’s Health Outcomes (ECHO) study.

Prerona Mukherjee, Ph.D.

Prerona Mukherjee, Ph.D.Prerona Mukherjee, Ph.D., completed her Masters in Cognitive Science from the School of Informatics at the University of Edinburgh, UK. She also obtained a Ph.D from the School of Medicine at the same University, focusing on models of emotion and information processing networks in Schizophrenia. She has a Bachelor of Engineering in Computer Science from the University of Pune, India and has also worked extensively in the software industry.

Her research is focused on interactions between emotion & cognition and their relationship to self-control and attentional control in individuals with different diagnosis (such as ADHD, Schizophrenia, etc). She is particularly interested in functional outcomes (such as academic achievement) and resilience, as well as helping to optimize these using novel interventions such as smart-phone and virtual reality based applications. She has previously studied emotion-cognition interactions in individuals with diagnoses such as schizophrenia and bipolar disorder and is currently focused on extending this research to individuals with ADHD.

Apart from research, she also likes to be involved in outreach and volunteer activities related to mental health.
