Shannon Hoffman, PT, DPT
Shannon 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.
Beatrice Menor, B.S.
Beatrice Menor, B.S., received her Bachelor's degree in Neurobiology, Physiology, and Behavior and minored in Psychology from UC Davis in June 2016. She is currently a Junior Specialist for the Attention, Impulsivity, and Regulation (AIR) Laboratory where she is responsible for running assessments, fMRI scans, and other day-to-day procedures involved with the Mapping Impulsivity's Neurodevelopmental Trajectory (MINT) study. Beatrice is an active coordinator for other studies within the lab involved in researching ADHD through behavioral interventions via virtual reality and other digital applications.

Agnieszka Mlodnicka, Ph.D.
Agnieszka 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., 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.
Jazmin Sheppard, M.A.
Jazmin Sheppard, M.A., received her Bachelor's degree in English and minored in Psychology from UC Davis in June 2013.

Jazmin is currently continuing her education at Alliant International University as a doctoral student where she expects to complete her Psy.D. in Clinical Psychology by June 2019. Jazmin has worked at the UC Davis MIND Institute for the past five years researching Autism, Down Syndrome, Fragile X, and ADHD in infants, children, adolescents, and adults. Currently, she works within the Attention, Impulsivity, and Regulation (AIR) Laboratory she is responsible for administering assessments and questionnaires to participants and families across multiple studies, writing reports, and offering support to supervisors and staff.
Ryan Shickman, B.S.
Ryan Shickman received his B.S. in psychobiology from UCLA in 2014 and he began work at the MIND Institute that same year. He is a doctoral student in the Clinical Psychology Psy.D. program at Alliant International University, Sacramento, and expects to graduate in 2021. During the past three years as a study coordinator, Mr. Shickman conducted assessments with research participants who have fragile X syndrome, Down syndrome, idiopathic intellectual disability, and autism. Shickman was also a volunteer co-leader for three years with the MIND Institute’s autism Social Skills program. Currently as a member of the Attention, Impulsivity, and Regulation (AIR) Lab he assists with organizing and running appointments for studies which either map the developmental trajectory of impulsivity or offer computerized behavioral interventions to improve symptoms.
