    Research Summary

    Dr. Askin's research efforts are clinicopathologic studies of neoplasms and other disease processes seen by the surgical pathologist. Electron microscopy, immunocytochemistry, flow cytometry and molecular biologic techniques are often used in these studies, but light microscopy and the clinical history remain important. Radiologic-pathologic correlation is also a valuable area of study.

    His particular fields of interest are adult and pediatric lung disease and the study of pediatric neoplasms. He and his team also see material from a wide spectrum of non-neoplastic interstitial lung diseases. Lung carcinomas collected in their SPORE study are used in molecular oncologic and clinico-pathologic studies.
