Research Interests

Joachim H. Ix, MD, MAS is a nephrologist and epidemiologist at UCSD. His research utilizes epidemiology and biostatistics to understanding mechanisms by which alterations in glucose and mineral metabolism contribute to cardiovascular disease risk among persons with kidney disease. His recent work has focused on the consequences of altered fetuin-A concentrations, a hepatic secretory protein that simultaneously inhibits vascular calcification and promotes insulin resistance. In addition, he works with cystatin-C, a novel endogenous measure of kidney function, determining whether this measure might provide novel insights towards cardiovascular disease mechanisms among persons with early kidney function decline.

Clinical Interests

Diagnosis and management of chronic kidney disease.

More about Dr. Ix

In 2007 Joachim H. Ix, MD, MAS joined the faculty of the Department of Medicine and Family and Preventive Medicine with appointments in the Division of Nephrology and Division of Preventive Medicine. He has a joint appointment with the Veterans Affairs San Diego Healthcare System, where is his currently the Director of the VA Dialysis Unit.

Along with his duties at the Veterans Affairs San Diego Healthcare System he has received three (3) Federally funded grants to research Fetuin-A, Diabetes, and other determinates of cardiovascular disease along with an American Heart Association, an American Diabetes Association Innovation Award in Geriatric Endocrinology and a Sandra B. Daugherty Foundation Award in Cardiovascular Epidemiology.

Dr. Ix began his academic career at the University of California, San Diego obtaining his bachelor’s degree in Biochemistry where he graduated Summa Cum Laude and Phi Beta Kappa. While attending UCSD as an undergraduate, he was also awarded Most Outstanding Senior in Biochemistry and Cell Biology Award. Continuing his education at the University of Chicago, Pritzger School of Medicine, Dr. Ix received his medical degree and was once again acknowledged for his academic excellence he was selected as a member of the Alpha Omega Alpha medical honors fraternity; he was awarded the Sandoz Award (outstanding extracurricular accomplishments during medical school),

Dr. Ix completed his internship and residency at the University of California, San Francisco Medical School in Medicine and later his rotation through Nephrology infl uenced his current career path into medical research. He was honored by receiving the Outstanding Intern award, as well as the TEACH Award for outstanding teaching, the Keith Johnson Award for outstanding second year resident.

While completing his internship and medical residency at the UCSF School of Medicine Dr. Ix obtained a Masters in Advanced Studies (MAS) degree in clinical research, biostatistics and epidemiology which prepared him for his career in medical research. During this time Dr, Ix was also the Chief Medical Resident for the UCSF School of Medicine, Department of Medicine and then a Fellow in Nephrology prior to his appointment as an Assistant Professor at UCSF in Nephrology. He began his teaching career as Chief Medical Resident and a Lecturer.

He now divides his times between the Veterans Affairs San Diego Healthcare System, where is his currently the Director, Dialysis Unit, and the UCSD School of Medicine, Department of Medicine, Division of Nephrology and the Division of Preventive Medicine where he focuses his research activities on Fetuin-A, Kidney Disease and Cardiovascular Disease.
