Major research interests:

- Analgesic nephropathy
- Mild chronic renal insufficiency: risk factors
- Hypertension: risk factors and prevention
- Gout: epidemiology
- Rheumatoid arthritis and cardiovascular disease
My research has examined the epidemiology of a variety of chronic diseases including nephrolithiasis, analgesic nephropathy, interstitial cystitis, hypertension, and hypertensive disorders of pregnancy. I have recently begun studying new areas, including gout and rheumatoid arthritis.
