He has contributed to several multicenter studies investigating biomarkers of AKI, including the TRIBE-AKI study, the Furosemide Stress Test study and several industry sponsored investigations. More recently he has begun developing and implementing an electronic health record derived AKI risk score, with the goal of improving the care of patients at high risk for the development of severe hospital acquired AKI. He has published over 90 peer-reviewed articles and book chapters on AKI and the care of patients with kidney injury in the ICU.
