    Biography

    Dr. Fernandez is a child psychiatrist and psychiatric geneticist who has an active clinical practice and research laboratory. Tom is a graduate of Princeton University and Yale School of Medicine, with additional research training at the National Institute of Mental Health in Bethesda, Maryland. He completed residency training in child, adolescent, and adult psychiatry in the Solnit Integrated Residency Program at Yale. As a faculty member in Yale Child Study Center and the Department of Psychiatry, Tom's research efforts include the following investigations into developmental neuropsychiatric disorders: (1) discovering genetic mutations in Tourette syndrome, motor stereotypies, obsessive-compulsive disorder, ADHD, and anxiety disorders using next generation DNA sequencing (whole genome and exome), and using these discoveries to identify treatment targets; (2) discovering epigenetic marker variation in these disorders; and (3) clinical trials of new behavioral and medication treatments. Tom has received research funding from the NIMH (K08, R01), Brain & Behavior Research Foundation (NARSAD), Simons Foundation, and Allison Family Foundation. Additionally, Tom works clinically as an attending in the Tourette/OCD/ADHD Clinic at Yale Child Study Center.

    Research

    Overview

    Dr. Fernandez's current focus is to discover which combinations of genes are underlying risk for these disorders in individuals and extended families. There are multiple pathways to this type of discovery, including identification of discrete genetic sequence changes in those with disease (using whole-exome and whole-genome DNA sequencing), detecting deletions and duplications that encompass larger regions of human chromosomes (using DNA sequencing and microarray technologies), and finding markers on DNA that regulate gene expression but do not alter the genetic sequence or structure (i.e. epigenetic markers that are dynamic throughout development). The end goal of this research is to identify networks of genes that increase risk for illness and teach us larger lessons about underlying disease biology that can be leveraged for improving diagnosis and treatment.
