Dr. Bottini discusses externalizing behavior among children with neurodevelopmental disabilities and a behavioral framework for how this behavior develops and persists over time. She describes how both the physical environment and others in the environment can play a role in these unmet needs. Finally, Dr. Bottini will provide an overview of effective behavioral strategies that address these needs and set up the environment for long term success.

About the speaker:

Summer Bottini, PhD, BCBA-D, received her doctorate in clinical psychology from Binghamton University and completed post-doctoral residencies at the Marcus Autism Center and May Institute. Dr. Bottini is an Assistant Professor in the Emory University School of Medicine Department of Pediatrics and a Psychologist in the Complex Behavior Support Program at Marcus Autism Center. Dr. Bottini specializes in the assessment and treatment of externalizing behavior among individuals with developmental disabilities. Additionally, her work is focused on the effective supervision of clinicians to provide optimal care for autistic and neurodivergent individuals. This includes embedding a neurodiversity framework within clinical practices, addressing staff burnout, effective/efficient training methods, and treatment fidelity.

Tune in to learn about ARI Research Grant recipient, Dr. DiCicco-Bloom’s ongoing research.

Approximately 17% of children are diagnosed with NDDs, including ASD, ADHD, and ID, which are highly heterogenous, frequently co-occur, and manifest in early life in sex-dependent fashion. We speculate that some of this heterogeneity is due to interactions between genetic risk factors and environmental exposures (G x E). During neurodevelopment, both the generation of new neurons, termed neurogenesis, and the gut microbiome are exquisitely sensitive to environmental factors, with recent evidence raising concern about childhood antibiotics. To examine this issue, we designed a new G x E model selecting 16p11.2 microdeletion mouse because this human variant increases ASD risk 38-fold, and exposure to the cephalosporin antibiotic, cefdinir. We assess effects on the gut microbiome, hippocampal neurogenesis and structure, gene expression, serum metabolome, and adult behaviors. Our preliminary results suggest that cefdinir exposure alters all these parameters, supporting a possible role of antibiotic-induced changes of the microbiome in ASD pathogenesis.

About the speaker:

Emanuel DiCicco-Bloom, MD, is a professor at the Department of Neuroscience and Cell Biology at Rutgers University, Robert Wood Johnson Medical School. His research interests include gene and growth factor regulation of neurogenesis during mammalian brain development, focusing on models of human neurodevelopmental disorders, including autism, schizophrenia, and environmental teratogens.

Research Interests: My main area of research is nervous system development and how abnormalities contribute to brain disease. As a physician-scientist, I am motivated to share knowledge of brain development and scientific discovery with the public, advising advocacy organizations and government agencies on how basic research can help address neurodevelopmental disorders. Building on our pioneering studies of neurogenesis, we defined how extracellular signals, receptors, and genes regulate signaling pathways that control proliferation to produce neurons in diverse brain regions including the cerebellum, cerebral cortex, and hippocampus. Importantly, mechanisms that stimulate or inhibit neurogenesis in culture models reliably translate into living animals. Learn more about Dr. DiCicco-Bloom
