I am a veterinary anatomic pathologist, in the Veterinary Diagnostic Laboratory, involved with many different species and pathologic disorders. This includes neoplasia in camelids and in horses, and non-neoplastic nodular skin disease in horses. I have a special interest in equine disease and in neuromuscular disease. I am currently involved in the diagnosis of equine polysaccharide storage myopathy by examination of muscle biopsy samples, and in studies involving the pathogenesis of abnormal polysaccharide storage in skeletal muscle..

Equine polysaccharide storage myopathy has been shown to be the major cause of a common muscle disorder of horses, known as exertional rhabdomyolysis or "tying up." Many other clinical manifestations, all related to abnormal muscle function, can also occur. The exact pathogenesis of equine polysaccharide storage myopathy is still not known, although pathologic findings of abnormal polysaccharide storage and response to diet change suggest abnormal metabolism of starch and sugar.
