Current Officers

 
Welcome to the Section on Medical Devices and Diagnostics
American Statistical Association 

The objective of the Section on Medical Devices and Diagnostics (MDD) is to serve Association members with special interests in the application and appropriate use of statistics to the design, development, evaluation, quality control and use of medical devices and diagnostic tests in humans and animals, where a simple definition of a medical device is any medical product that does not work solely by chemical or biological means.

Any members of the American Statistical Association who are interested in medical devices and diagnostics can join this section. MDD is also on Twitter!




Selected officers organize events, initiatives, communications, and focus the energies of MDD's members toward advancing our common causes. Meet the MDD officers below.
