EDUCATION

  • B.S., Psychology, University of New Mexico, Albuquerque, NM (1979)
  • M.S., Psychobiology, University of New Mexico, Albuquerque, NM (1982)
  • Ph.D., Psychology, University of New Mexico, Albuquerque, NM (1985)

RESEARCH AREA

In 1989, Dr. Hovda was recruited by the Department of Neurosurgery to direct its scientific efforts to understand the cellular pathophysiology of brain injury. This work resulted in providing the backbone for UCLA being recognized as a "Center of Excellence" by the National Institutes of Health.He has devoted most of his career to understanding the mechanisms of recovery of function. Dr. Hovda is the Director of the UCLA Brain Injury Research Center. He is a former President and current President - Elect of the National Neurotrauma Society and study section committee chair for the National Institute for Neurological Disease and Stroke (NINDS). He is the current chair for the Brain Injury and Neurovascular Pathologies study section for the NINDS and has been elected President of the International Neurotrauma Society (2009-2012). Dr. Hovda has received a number of awards for his research on brain injury and recovery of function, including the 1991 National Head Injury Foundation Award, the Giannini Foundation Award, the Benjamin Franklin Haught Memorial Award and named the Lind Lawrence Eminent Scholar for his work on the topic of Traumatic Brain Injury. In addition Dr. Hovda received the 2006 Women in Neurotrauma award for his teaching and support for women in neuroscience. Dr. Hovda is most well known internationally for his translational work on the pathobiology of traumatic brain injury.

GRANTS

  • R01 (NS045804) Gómez-Pinilla (PI) 12/01/04 – 11/30/09 Role: Co-Investigator
    NINDS/NIH Division of Stroke and Trauma
    “Activity-Induced Recovery Following Brain Trauma”
    To determine if reduced cognitive capacity following TBI is the result of dysfunction in the molecular mechanisms that support synaptic plasticity.
  • R01 (NS050465-01) Gómez-Pinilla (PI) 7/01/05 – 6/30/10
    NINDS/NIH Division of Stroke and Trauma
    “Restoration of Homeostasis After Brain Trauma”
    The major goals of this project are to determine mechanisms involved in oxidative stress and energy crisis in traumatic brain injury, and the possibility to modulate free radical formation by restoring brain homeostasis.
  • R21 (NS048535-01A1) Griesbach (PI) 4/01/05 – 3/31/07 Role: Co-Investigator
    NINDS/NIH Division of Stroke and Trauma
    “Voluntary Exercise Therapy After Traumatic Brain Injury”
    To determine whether voluntary exercise up-regulates BDNF following traumatic brain injury.
  • R01 (NS052406-01) Prins (PI) /01/05 – 6/30/08 Role: Co-Investigator
    NINDS/NIH Division of Stroke and Trauma
    “Age-Dependent Ketone Metabolism After Brain Injury”
    To determine the use of ketone bodies as an alternate metabolic substrate following traumatic brain injury in the developing brain.
  • R01 (NS049471) Vespa (PI) 1/01/06 – 12/31/10 Role: Co-Investigator
    NINDS/NIH Division of Stroke and Trauma
    “MRS Detects Metabolic Dysfunction after Brain Injury”
    This application focuses on the consequences of traumatic brain injury on the human brain to utilize oxygen. Traditional measurements of the cerebral metabolic rates for oxygen will be compared to magnetic resonance spectroscopy to determine the degree of mitochondrial dysfunction as it relates to posttraumatic atrophy.
  • R01 (NS 027544-10) Hovda (PI) 1/19/06 – 12/31/09 Role: Principal Investigator
    NINDS/NIH Division of Stroke and Trauma
    “Loss of Developmental Plasticity Following Head Injury”
    The primary goal of this project is to characterize the morphological, behavioral and molecular response to traumatic injury in the immature brain as it relates to enriched environment-induced experience-dependent plasticity.
