This program is fortunate to include such strong departments of Neuroscience and Genetics/Genomics at Mount Sinai, a new Institute and facilities, and such strong connections between these Departments, Institutes and the Department of Psychiatry. Thus, there are many research faculty members who are well qualified as PhD preceptors for trainees in this program. In conjunction with the Advisory Committee, we have selected the following as our primary list of potential PhD preceptors; it includes both established full professors, and some younger faculty members with exciting current research. This presents to our trainees those whom we believe have a strong capability, and interest, in training psychiatrists to do translational research. They are listed alphabetically with their primary appointment.
Schahram Akbarian, MD, PhD (Psychiatry)
Dr. Akbarian employs an array of methods, including cell type-specific chromatin sortings in human, non-human primate and rodent brain, as well as conditional deletions of chromatin modifying proteins in genetically engineered mice. These methodological approaches are aimed at uncovering epigenetic regulations that are unique to the human brain, as well as testing the role of specific chromatin remodeling mechanisms in normal and diseased brain development. One particular focus is the regulation of histone methylation markings associated with transcription start sites and other regulatory sequences at the 5’-end of genes. This includes behavioral studies and transcriptome and epigenome mapping in mutant mice with demethylases that were recently implicated in the neurobiology and genetics of some cases on the autism, mood, and psychosis spectra. In parallel, the lab charts on a genome-wide scale the epigenetic architecture of cortical neurons, including occupancies of histone methylation markings, in postmortem brain of subjects diagnosed with schizophrenia, depression, or autism. Finally, the lab measures the ”epigenetic distance” between different cell types residing in the same tissue/same subject. Such comparative epigenome mapping is expected to provide novel, unprecedented insights into the role of regulatory, non-coding sequences important for cellular differentiation, as well as hominid brain evolution.
Mark Baxter, PhD (Neuroscience)
The Baxter lab focuses on the neural mechanisms of learning, memory, executive function, and decision-making, and the ways in which these mechanisms fail in aging and neuropsychiatric disorders. Baxter’s research interests include the functional neuroanatomy of frontal and temporal cortex, regulation of higher cognitive functions by neuromodulators, the biological basis of cognitive impairments in neurodegenerative disease and neuropsychiatric conditions, as well as the neurobiological and cognitive effects of general anesthesia.
Deanna Benson, PhD (Neuroscience)
The Benson lab has been investigating mechanisms promoting axon guidance and targeted synapse assembly in the rodent hippocampus and cerebral cortex, focusing on molecules mediating cell-cell recognition and adhesion. The function of adhesion molecules (e.g. L1, semaphorins, and cadherins) and the ERM (ezrin, radixin, and moesin) family of actin linker proteins in axonal guidance, and in the regulation of synapse specificity and laminar targeting, is being investigated.
Kristen Brennand, PhD (Psychiatry)
Dr. Brennand’s research focuses on using human induced pluripotent stem cells to model psychiatric disorders. By reprogramming skin samples from patients with schizophrenia (SZ) into stem cells and then differentiating these stem cells into neurons, she showed that SZ neurons had reduced neuronal connectivity and aberrant gene expression; some of these defects were improved by treatment with antipsychotic medications, as published in Nature in 2011. She is now expanding her studies to include better clinically characterized patients, including a cohort of childhood onset SZ patients and a second cohort of monozygotic (MZ) twins discordant for SZ. Her lab seeks to define the disrupted molecular pathways and cellular processes that contribute to schizophrenia.
Joseph Buxbaum, PhD (Psychiatry)
Laboratory of Molecular Neuropsychiatry
The lab studies human psychiatric and neurological diseases using the methods of cell biology, molecular biology, genetics, genomics, and animal models. Currently, Dr. Buxbaum’s lab is focusing on Alzheimer's disease, autism, and schizophrenia. The focus in Alzheimer's disease is on the accumulation of the pathological amyloid A beta protein, and how amyloid protein precursor (APP) cleavage may regulate transcription. In autism, the lab is using techniques of molecular genetics to identify, and then characterize, genes that contribute to autism susceptibility, carrying out whole exome sequencing to identify de novo mutations in autism. The lab has several rodent models where autism genes have been mutated. In the case of the Shank3 gene, Dr. Buxbaum’s studies have led to an ongoing clinical trial. In schizophrenia, the lab is following up on microarray studies that implicate oligodendrocyte abnormalities in schizophrenia. They have made relevant mouse models and are exploring methods of deriving neurons from patient samples together with collaborators, Drs. Sklar and Brennand.
Patrizia Casaccia, MD, PhD (Neuroscience)
Laboratory of Epigenetics of Neural Repair
Dr. Casaccia’s work adopts molecular and cellular techniques to find new therapies for multiple sclerosis. Her work includes translational research in regenerative and personalized medicine. The lab focuses on myelin repair with a special emphasis on the effect of aging and gender in patients with MS leading to novel screening for the discovery of new therapies to protect the neurons and replace damaged myelin. Recently, the Casaccia lab has investigated the effect of emotional stress on myelin, hence, addressing high comorbidity between MS and depression.
Elizabeth Cropper, PhD (Neuroscience)
The cellular and molecular mechanisms that endow neural circuits with the ability to respond to changes in the external environment, simultaneously maintaining coordinated patterns of activity, are being investigated in an experimentally advantageous preparation, the marine mollusk Aplysia Californica.

George Huntley, PhD (Neuroscience)
Dr. Huntley's principal research focus is on mechanisms of synaptic plasticity through which synaptic structure and function are modified developmentally, by learning and memory, and following injury. Current research projects include: 1) determining the role of adhesion and related molecules in synaptic function; 2) characterizing roles of several autism-linked genes in establishment and plasticity of cortical sensory maps; 3) molecular mechanisms of hippocampal synaptic remodeling.
Yasmin Hurd, PhD (Psychiatry)
The Hurd lab investigates the relationship between psychiatric and drug abuse disorders with a growing emphasis on identifying factors that increase the risk for these disorders. Work is focused on systematic study of the human brains of drug abusers and subjects with psychiatric disorders in relation to opioid neuropeptide, cannabinoid and dopamine neural systems, mapping specific genes in the mesocorticolimbic system that regulate emotional function.
Hirofumi Morishita, MD, PhD (Psychiatry)
Developmental Brain Plasticity & Cognition
Following PhD and psychiatry residency in Japan, his research focuses on understanding the mechanisms of experience-dependent brain plasticity during developmental critical periods. By combining molecular, circuit, and systems level methodologies in mouse visual cortex, he identified novel molecular “brakes” on adult plasticity, the removal of which led to successfully restored juvenile brain plasticity in adulthood. His current research aims to translate the critical period principle beyond vision and toward an understanding of neurodevelopmental disorders such as schizophrenia.
John Morrison, PhD (Neuroscience)
Dr. Morrison’s lab studies the molecular and structural nature of age-related alterations in synaptic plasticity that lead to decreased cognitive function and/or degeneration, and links between age-related decreases in estrogen levels (i.e., menopause), NMDA receptors, and cortical circuits. Cellular neuropathologic analyses of human brain, experimental and neuropathologic analyses of non-human primate cortex, and detailed neuropathologic analyses of genetically manipulated mice, are involved.
Eric Nestler, MD, PhD (Neuroscience)
Dr. Nestler's research focuses on the role of the brain's reward pathways in the regulation of mood and motivation under normal conditions and its contribution to depression and antidepressant action in animal models. Regulation of reward pathway function by transcriptional mechanisms, in particular stress-induced transcription factors such as CREB and DeltaFosB and their physiological target genes, and epigenetic mechanisms that provide insight into stress and antidepressant action, are studied.
Dalila Pinto, PhD (Psychiatry)
Her research focuses on understanding how the human genome varies in sequence, structure and copy number, and how this genetic variation contributes to phenotype differences and disease risk in families and populations. Over the past five years she has played a leading role in mapping and characterizing the functional impact of structural variants (e.g., deletions, duplications, inversions and complex rearrangements) in autism and other disorders. By using a combination of high-throughput technologies together with bioinformatics and statistical genetics, her current research aims to integrate various forms of genetic variation with gene expression, epigenetics and clinical data, to identify genes and biological pathways involved in autism and related neurodevelopmental disorders.
Shaun Purcell, PhD (Psychiatry)
Center for Statistical Genetics
Dr. Purcell’s methodological work focuses on the design of genetic studies, the detection of gene variants influencing complex human traits and the dissection of these effects in the larger context of other genetic and environmental factors. His group develops widely used genetic tools, including the software package PLINK, a toolset for the analysis of whole-genome association studies cited over 3000 times in the last 5 years. Current foci include leading the analysis of a large-scale whole-exome sequencing study of schizophrenia and bipolar disorder and developing computational tools for the analysis of next-generation sequencing data.
Scott Russo, PhD (Neuroscience)
The Russo lab investigates how the brain adapts to stress and drugs, leading to altered synaptic connectivity and behavioral changes relevant to depression and addiction. Behavioral models are analyzed by molecular, biochemical, and neuroanatomical techniques. Recent work, for example, has demonstrated a role for synaptic plasticity within the brain’s reward circuitry in mediating the deleterious effects of stress as well as the importance of peripheral immune cytokines in mediating some of this stress-induced cellular and behavioral pathology.
Stephen Salton, MD, PhD (Neuroscience)
Dr. Salton studies the function of neurotrophic growth factors such as BDNF and NGF by identifying the target genes that they regulate, signaling pathways involved in gene induction, and the role that these downstream gene products play in CNS and PNS development and function, and in the regulation of complex behavior, including depression and memory.
Eric Schadt, PhD (Genetics/Genomics)
Institute of Genomics and Multiscale Biology
One of the world’s foremost experts in computational biology, he has focused on the generation and integration of large-scale sequence variation, molecular profiling and clinical data in disease populations to construct predictive network models of disease, providing for direct links between molecular biology and the pathophysiology of disease. He has contributed to a number of discoveries relating to the genetic basis of common human diseases such as diabetes and obesity.
Daniela Schiller, PhD (Psychiatry)
Laboratory of Affective Neuroscience
Dr. Schiller's research focuses on the neural mechanisms underlying emotional control. In that the environment we live in is constantly changing, our learned emotional responses need to be continuously updated to appropriately reflect current circumstances. Understanding the neural mechanisms that make such emotional flexibility may shed light on the impairments leading to anxiety disorders.
