Current Research and Scholarly InterestsAutism spectrum disorders (ASD) are among the most pervasive neurodevelopmental disorders and are characterized by significant deficits in social communication. A common observation in children with ASD is that affected individuals often “tune out” from social interactions, which likely impacts the development of social, communication, and language skills. My primary research goals are to understand why children with ASD often tune out from the social world and how this impacts social skill and brain development, and to identify remediation strategies that motivate children with ASD to engage in social interactions. The theoretical framework that guides my work is that social impairments in ASD stem from a primary deficit in identifying social stimuli, such as human voices and faces, as rewarding and salient stimuli, thereby precluding children with ASD from engaging with these stimuli.
My program of research has provided important information regarding the brain circuits underlying social deficits in ASD. Importantly, these findings have consistently implicated key structures of the brain’s reward and salience processing systems, and support the hypothesis that impaired reward attribution to social stimuli is a critical aspect of social difficulties in ASD. The first study produced by this program of research was published in the Proceedings of the National Academy of Sciences and showed that children with ASD have weak brain connectivity between voice processing regions of cortex and the distributed reward circuit and amygdala. Moreover, the strength of these speech-reward brain connections predicted social communication abilities in these children. A second study, which was recently published in eLife, examined neural processing of mother’s voice, a biologically salient and implicitly rewarding sound which is associated with cognitive and social development, in children with ASD. Results from this study identified a relationship between social communication abilities in children with ASD and brain activation in reward and salience processing regions during mother’s voice processing. A third study, published in Proceedings of the National Academy of Sciences, showed that mother’s voice activates an extended voice processing network, including reward and salience processing regions, in typically developing children. Moreover, the strength of brain connectivity between voice-selective and reward and salience processing regions predicted social communication abilities in these neurotypical children. Together, results provide novel support for the hypothesis that deficits in representing the reward value of social stimuli, including the human voice, impede children with ASD from actively engaging with these stimuli and consequently impair social skill development.
My future research will leverage these findings by examining several important questions related to social information processing in children with ASD. First, we aim to study longitudinal development of social brain circuitry in minimally verbal children with ASD, a severely affected subpopulation that has been vastly underrepresented in the ASD literature. Second, we aim to examine the efficacy of naturalistic developmental behavioral interventions, such as Pivotal Response Treatment, for children with ASD and their relation to changes in social brain and reward circuitry. Third, we aim to examine distinct neural profiles in female children with ASD who, on average, have better social communication abilities compared to their male counterparts.
Assistant Professor of Chemical Engineering and of Genetics
Current Research and Scholarly InterestsWe study the role of the lysosome in metabolic adaptation using subcellular omics approaches, functional genomics and innovative biochemical tools. We apply this knowledge to understand how lysosomal dysfunction leads to human diseases including neurodegeneration, cancer and metabolic syndrome.

Assistant Professor of Radiology (Neuroimaging and Neurointervention) and, by courtesy, of Psychiatry and Behavioral Sciences and of Materials Science and Engineering
Current Research and Scholarly InterestsOur goal is to develop and clinically implement new technologies for high-precision and noninvasive intervention upon the nervous system. Every few millimeters of the brain is functionally distinct, and different parts of the brain may have counteracting responses to therapy. To better match our therapies to neuroscience, we develop techniques that allow intervention upon only the right part of the nervous system at the right time, using technologies like focused ultrasound and nanotechnology.

BioNeal D. Amin, MD, PhD is a practicing Stanford psychiatrist and neurobiologist who studies human cellular neurodevelopment - the process by which genetic and molecular pathways give rise to immense cellular diversity in the human brain during embryonic development. A more complete understanding of human cellular neurodevelopment will lead to the next generation of targeted therapeutics for wide ranging neuropsychiatric conditions.
Dr. Amin completed his graduate work with Professor Samuel Pfaff (Salk Institute) where he investigated the regulatory dynamics of a miRNA associated with neurodegeneration using mouse genetic models, single cell RNA sequencing, in vivo CRISPR/Cas9, and linear and non-linear models of the impact of gene dose variation on neurodevelopment and mammalian survival (see: Amin, N.D., et al., Science, 2015; Amin, N.D.*, et al., Neuron 2021, Amin, N.D.*, et al. STAR Protocols; *co-corresponding author). At Stanford, Dr. Amin worked with Stanford Professor Sergiu Pasca, MD to use stem-cell derived human brain organoids as model of neurodevelopment and pathophysiology of psychiatric disorders such as 22q11 deletion syndrome and motor neuron diseases. Human brain organoids are three dimensional cellular models of the human nervous system that recapitulate complex macrostructural and cellular features of the human brain. He published a highly cited review on the utility of human brain organoid technology for studying psychiatric disorders (Amin, N.D., and Pasca, S.P. Neuron, 2018). Dr. Amin is principal investigator on awards from the NIH/NINDS (K08 Career Development Award) and the Brain and Behavior Research Foundation (NARSAD Young Investigator Award). He has particular interest in leveraging cutting-edge biological technologies and bioinformatics to advance the investigation of neurological and psychiatric disorders.
Dr. Amin completed the Stanford Psychiatry Research Track Residency Program and completed the Palo Alto Psychoanalytic Psychotherapy Training Program Fellowship Year. He was recognized with the Outstanding Resident Award from the NIMH/NIH for his academic contributions. He recognizes the critical importance of advancing human neuroscience for the countless patients and families suffering from neuropsychiatric disorders that lack effective treatments. He is a practicing therapist and psychiatrist in Stanford's Evaluation Clinic.
Kanwaljeet S. Anand
Professor of Pediatrics (Pediatric Critical Care) and of Anesthesiology, Perioperative and Pain Medicine
Current Research and Scholarly InterestsDr. Anand is a translational clinical researcher who pioneered research on the endocrine-metabolic stress responses of infants undergoing surgery and developed the first-ever scientific rationale for pain perception in early life. This provided a framework for newer methods of pain assessment, numerous clinical trials of analgesia/anesthesia in newborns, infants and older children. His research focus over the past 30+ years has contributed fundamental knowledge about pediatric pain/stress, long-term effects of pain in early life, management of pain, mechanisms for opioid tolerance and withdrawal. Current projects in his laboratory are focused on developing biomarkers for repetitive pain/stress in critically ill children and the mechanisms underlying sedative/anesthetic neurotoxicity in the immature brain. He designed and directed many randomized clinical trials (RCT), including the largest-ever pediatric analgesia trial studying morphine therapy in ventilated preterm neonates. He has extensive experience in clinical and translational research from participating in collaborative networks funded by NIMH, NINDS, or NICHD, a track-record of excellent collaboration across multiple disciplines, while achieving success with large research teams like the Collaborative Pediatric Critical Care Research Network (CPCCRN). He played a leadership roles in CANDLE (Condition Affecting Neuro-Development & Learning in Early infancy) and other activities of the Urban Child Institute and UT Neuroscience Institute. More recently, he led the NeoOpioid Consortium funded by the European Commission, which collected data from 243 NICUs in 18 European countries.
