The Role:

Data Scientists at Grand Rounds work on problems that are core to the company’s mission. Major challenges include developing systems and models to identify the highest quality doctors in the country as well as methodologies to uncover the subtle differences between each physician’s clinical expertise.  Additionally, patient-level modeling allows us to understand the specific healthcare needs of every person.  With a high fidelity understanding of both patients and physicians we are able to route patients to both appropriate and high quality care.  

In addition to developing the company’s core technologies, data scientists provide decision support analysis for many teams across the organization including product development, sales, marketing, and strategy.  Data scale ranges from small data sets that fit on a single laptop to large multi-terabyte clinical information in distributed database systems.
