    Dr. Johansen is Professor of Medicine in Residence and is Director of Dialysis at the San Francisco VA Medical Center.

    Dr. Johansen's research focus is patient-oriented research among patients with chronic kidney disease (CKD) and end-stage renal disease (ESRD). In particular, she studies the pathogenesis of debility and evaluates therapeutic strategies to improve functional status in patients on dialysis, addressing these issues through several lines of investigation, including primary data collection through cohort and interventional studies and through use of national data available through the United States Renal Data System (USRDS). Mentoring is also an important focus for Dr. Johansen, and she holds a K24 to support her mentoring efforts.

    Dr. Johansen currently serves as Deputy Editor for the Clinical Journal of the American Society of Nephrology.
