    Laura Michele Hack

    Clinical Instructor, Psychiatry and Behavioral Sciences

    Bio Dr. Laura Hack is a Postdoctoral Fellow and Clinical Instructor under the mentorship of Drs. Leanne Williams, Alan Schatzberg, and Ruth O’Hara. She is a translational clinician with a research passion for integrating multiple types of biological and environmental data using advanced analytic techniques into a neuroscience-based taxonomy of mood, anxiety, and stressor-related disorders. Laura envisions herself as a ‘psychiatrist of the future,’ incorporating genetic information, brain imaging, blood-based markers, and data from wearable sensors into diagnostic and treatment decisions to help relieve the suffering that arises from our current trial-and-error approach.

    Current Research and Scholarly Interests My research interests are broadly in eating and mood disorders. My research program is comprised of two primary lines of research. First, I am interested in elucidating the mechanisms of eating and internalizing disorders, with an emphasis on understanding the neural mechanisms of these disorders. Second, I study novel methods of diagnosis and classification of eating disorders and eating behaviors, especially dietary restraint. A long-term goal of my research is to leverage findings to improve treatments for those with eating disorders.

  • Alesha Heath

    Alesha Heath

    Postdoctoral Research Fellow, Psychiatry

    Bio Dr. Alesha Heath is a Postdoctoral Scholar at Psychiatry and Behavioral Sciences at Stanford School of Medicine and the MIRECC the VA Palo Alto. She earned her PhD from the University of Western Australia and Sorbonne University.

    Dr. Heath's research has been primarily focused on the mechanisms and applications of brain stimulation therapies, in particular repetitive transcranial magnetic stimulation. Her research involves both basic and clinical components with the aim of improving the efficacy of these therapies for the treatment of disorders such as depression and Alzheimer's disease.

    Bio The overarching goal of my research is to identify neurobiological subgroups and develop objective treatment prediction markers for children with neurodevelopmental disorders in order to improve biologically-based diagnosis and advance individualized treatment. Biologically-based diagnosis and treatment is extremely limited for neurodevelopment disorders but also critically-needed to increase early identification and improve treatment outcomes, especially for pervasive disorders such as autism spectrum disorder (ASD) in which early intervention is often the most efficacious. My early career training has focused on developing expertise to study the neurobiology and treatment of ASD and my research has primarily focused on the application of non-invasive neuroimaging approaches to examine brain-behavior relationships and treatment outcomes.

    Thus far, my primary contributions to science fall within four primary categories: 1) identifying the neural correlates of cognitive/behavioral deficits, 2) investigating the neurobiological substrates of treatment response, 3) examining the etiological factors that contribute to alterations in brain development, and 4) contributing to ASD-related resources. My early research investigated the mechanisms associated with the cognitive deficits of alexithymia and dyslexia to further develop theories of the underlying neurobiology. My subsequent dissertation research, in which I began to focus on ASD, examined the neural correlates of treatment response to beta-blockers in adults with ASD and also assessed the contribution of cerebellar circuits to symptom presentation. I am also further developing my expertise for assessing young children with ASD in my current postdoctoral position at Stanford. My most recent research has primarily focused on examining the neural correlates of treatment response as well as the etiological factors that contribute to brain development in twins with ASD.

    Current Research and Scholarly Interests I am broadly interested in understanding how neuromodulatory systems (particularly those that use dopamine) govern long-term changes in neural signaling, anxiety behaviors, and reward-associated behaviors. I also have a strong interest in the biophysics and pharmacology of GABA type A receptors and how signaling at these receptors modulates brain circuitry. I primarily use optogenetics, electrophysiology, and rodent behavioral assays to address critical questions in these areas.
