Transfusion strategies in bleeding patients
In-vivo red cell labeling
Patient health numeracy
Statistical methods and study design in clinical research
Our research is focused on understanding changes in red cell mass and improving the storage and post-transfusion survival of blood components. Through a collaboration with the Trace Elements group at the Wisconsin State Lab, we are currently investigating novel methods for in-vivo red cell and platelet labeling using non-radioactive chromium isotopes detected with ultra-sensitive sector-field, induction-coupled, plasma mass spectroscopy (SF-ICPMS). I am also interested in how patients’ understanding of numbers – “health numeracy” – is associated with their ability to understand health information and make congruent decisions about their health care. We are currently following a cohort of patients to determine how health numeracy is associated with surgical outcomes, end-of-life planning, and health care utilization.
I also have a personal interest in statistical methods and study design in clinical research.
