Associate Professor of Clinical Pathology and Cell Biology at CUMC
Research Summary

My research interests focus on Laboratory Hematology and Clinical Laboratory Management. Our recent work in Laboratory Hematology includes descriptions of how to optimize flagging criteria of automated cell counters and a protocol for faster reporting of the absolute neutrophil count (ANC) from certain blood samples. In Laboratory Management, we have shown that the “accessioning-to-result” time does not always accurately reflect laboratory performance. We have also described the clinical and analytical performance of a new blood analysis system.
