Eric Johnson, MS, completed the University of Washington’s biostatistics master’s program in 2008. His thesis explored common theoretical problems involved with missing data. He quantified them, highlighting conditions leading to suboptimal performance, and provided new guidelines for using various multiple imputation techniques.
During his time at KPWHRI, Mr. Johnson has been involved with multiple projects involving direct intervention with the care-delivery system, observational studies and microsimulation modeling on colorectal and ovarian cancer, massage therapy, and estimating radiation exposure from medical imaging. His current responsibilities lie in research on obesity, opioids, and mental health.
Before earning his master’s degree, Mr. Johnson worked for four years as a research assistant on the Multi-Ethnic Study of Atherosclerosis (MESA), performing statistical analyses, verifying incoming data, and developing a process for providing data sets to all MESA researchers. Later, he was a research statistician with the Department of Veteran Affairs (VA), serving as the primary analyst in an investigation of how well VA hospitals performed non-cardiac surgeries. Mr. Johnson assessed statistical models used by the National Surgical Quality Improvement Program—then devised, tested, and implemented improved models, reporting his findings to VA leadership.
