Description of Research Expertise

- Molecular neuropharmacology of sleep and sleep-related respiratory disorders (obstructive sleep apnea).
- Neurobehavioral effects of early developmental alcohol exposure.
- Central control of breathing and its postnatal development.
- Molecular and cellular mechanisms of hypoxia.
- Molecular mechanisms of metabolic disorders (diabetes).

- In vivo rodent studies with administration of experimental compounds and molecular, physiologic, and behavioral endpoints.
- Quantitative analysis of mRNA and protein markers in tissue microsamples (quantitative RT-PCR and Western blot).
- Molecular profiling at the single-cell level (single-cell RT-PCR, immunocytochemistry, immunohistochemistry).
- Rodent behavioral tests, polysomnographic monitoring and scoring of sleep-wake behavior.
