Research Interests

  • Brain response to traumatic, ischemic or inflammatory insults
  • Sex differences and gonadal hormone modulation of brain function in health and disease
  • Development and validation of radiopharmaceuticals for non invasive imaging of neurotransmitter and hormone markers in the brain

Preclinical/postmortem studies:

1. Markers of neuroinflammation and neuroplasticity in hippocampus and basal ganglia of subjects who died with Alzheimer’s disease and matched, non-demented controls: Autoradiographic and immunohistochemical studies

2. Effects of maternal immune activation (an animal model of schizophrenia and autism) on neuroinflammation and neuroreceptor markers in brains of male and female offspring: Autoradiographic and immunohistochemical studies

3. Effects of mild traumatic brain injury on neurological status, working memory, neuroinflamation and neuroreceptor markers in mice subjected to single or repeated cuncussion.

PET imaging studies:

1. Brain Aromatase Availability in Steroid Users: a PET Study Using [C-11]Vorozole

The major goal of this project is to use positron emission tomography and the radiotracer [11C]vorozole for the evaluation of the effect of steroid abuse on regional brain aromatase (supported by NIDA)

2. Assessing the role of [11C]vorozole in the detection of aromatase in breast cancer

Specific aims: Evaluate the sensitivity and specificity of the C11 labeled aromatase inhibitor vorozole in the detection of aromatase in breast cancer patients.(Supported by NCI)

3. Neuroinflammation, NMDA receptors and cognitive function in chemobrain

The goal of this project is to evaluate the effect of chemotherapy on cognitive function measured by neuropsychological tests and on neuroinflammation and NMDA receptors using PET with the radiotracers [11C]PK11195 and [11C]CNS5161 (supported by NCI)

Other  projects performed with outside collaborators:

1. Sex differences in hippocampal volume, metabolism and amylind deposition in healthy individuals, those  with amnestic mild cognitive impairment and those diagnosed with Alzheimer’s disease.

2. Quantitative MRI of the developing fetal brain in utero: effects of genetic and environmental insults on fetal brain morphology, regional volumes and water diffusivity

3. Profiling the placebo responder: Neuropsychological, genetic and imaging studies comparing placebo responders to non-responders in an experimental pain paradigm.
