 Biostatistics is a branch of statistics that apply to human health data. So we use the statistical tools to identify how disease develop and how treatment works. I came to Kaiser Permanente Research Evaluation because the data from Kaiser Permanente electronic medical record collected for many years, you know, for many disease and then you need a long history to know what's going on. And it's almost impossible to start collecting information from beginning and follow the cohort for a long time to study that. But here we have the resource for us to do that because our members are stable for a long time. The moms are here, the children are here and naturally they will follow us. So we can use that to see in a long term how disease develop. And the data is important because the results we generate will help patients prevent the disease and learn what the best treatment option for their health. Also we partner with our physicians and our statisticians helping analyze data address the question came from physicians so those results we generate can directly apply to translate to the care of our members and also to everyone else in the world.
