Biography
My research addresses clinical questions by studying human subjects or patients. I collaborate with other faculty in the department on my research and provide expertise in the following areas: data analysis and statistics; mathematical modeling; data acquisition programming; human studies; respiratory physiology.
My research involvement has included multiple different projects:
• Accuracy of pulse oximetry, including determination of methemoglobin, carboxyhemoglobin, and the accuracy of cerebral oximetry.
• Organ transplantation and efforts to improve the quality of cadaveric organs.
• Acute normovolemic hemodilution to study the tolerance of acute anemia, as a way to examine red cell transfusion thresholds. Additionally, we have used this model to study other issues in transfusion, including TRALI.
• The utility of somatosensory and motor evoked potential, which are used in major spine surgery to assess the integrity of spinal cord function.
• The physiology of breathholding and drug-induced apnea.
• High altitude physiology
• Clinical effects of neuromuscular blockade
