The combination of our unique individual strengths and diverse backgrounds has cultivated a strong, supportive team that expands our research in the Ellison lab. We work very closely with the McCormick Lab and the Gurley Lab in the Division of Nephrology and Hypertension.

Special thanks to Jonathan Nelson, Ph.D. for sharing his art and time to take most of our photographs below.

David H. Ellison, M.D.

Principal investigator

David H. Ellison, MD Principal Investigator in the Ellison Lab

David has been a leader in defining how mutations in a novel kinase pathway cause Familial Hyperkalemic Hypertension by altering distal salt transport, and has defined how a high potassium diet reduces kidney salt transport.

Ryan Cornelius, Ph.D.

Instructor of Medicine

Ryan J. Cornelius, PhD Post-doctoral Fellow in the Ellison Lab, 2018

Ryan's research focuses on the cullin 3 mutant that causes Familial Hyperkalemic Hypertension and the role of the COP9 Signalosome.


Xiao-Tong Su, Ph.D.

Post doctoral fellow

Xiao-Tong Su, PhD Post-doctoral Fellow in the Ellison Lab, 2018

Xiao-Tong's current work focuses on the regulation of the sodium chloride cotransporter in the distal nephron, kidney remodeling, and optical tissue clearing.

Yujiro Maoka, MD/PhD

Post doctoral fellow

Yujiro Maeoka Post Doctoral Researcher Current
McCormick Lab

Yujiro Maeoka received his M.D. from Hiroshima University, Hiroshima, Japan in 2009. He was awarded a Ph.D. by Department of Nephrology, Hiroshima University in March 2019. His graduate work focused on the role of kidney specific ubiquitin ligase, which protects cells from hypertonic stress. His current work focuses on the role of mutations in CUL3, a key regulator of WNK-SPAK/OSR1 Kinase signaling pathway, in the pathogenesis of Familial Hyperkalemic hypertension (FHHt).

Jonathan W. Nelson, Ph.D.

Instructor of Medicine

Jonathan Nelson, PhD Senior Research Associate (Gurley Lab Collaborator) in the Ellison Lab, 2018
Gurley Lab

Jonathan is interested in understanding how cardiovascular disease is exacerbated by damage to endothelial cells and developing new therapeutic strategies aimed at improving endothelial cell function.  


Josh Robertson, B.S.

Senior research associate

Josh Robertson (Gurley Lab) Collaborator in the Ellison Lab
Gurley Lab

Josh has been at OHSU since 2007 and joined the Gurley lab in the spring of 2018. Josh manages the Gurley lab, maintains the animal colony, and leads animal studies and surgeries.
