Biostatistics and Much More 

Our Center comprises two teams of experts who work seamlessly together to support the full research lifecycle.  

Our biostatisticians help researchers review the design and implementation to ensure that the research questions can be answered as intended, understand limitations, and study constraints, and better stand up to critical review.  

Our data informatics team provides data capture and management expertise that facilitates better organization and use of data capture tools, better accuracy of data capture with defined coding of variables, and a better interface to analysis requirements.
