May 19, 2015 — Niall Brennan is the chief data officer for the Centers for Medicare and Medicaid Services(CMS).

Brennan has an outstanding background in the private and public sectors, including work on Capitol Hill.

In his work at CMS, he has been heavily involved in the two main information federal initiatives — big data and healthcare IT.

For the past five years he has been face first in the battle to release information for public consumption.

The dilemma is obvious.

His agency is tasked with releasing open data sets to the public, yet much of the data is medical and has personal information attached.

During the interview, Brennan talks about the strategy for open data release that has been successful at the CMS.

The discussion included diverse topics that ranged from data curation, visualization, sharing and storage.

If you are charged with taking large data sets with sensitive information and releasing them for public consumption, then this is a great place to start.

Brennan is involved with the Healthcare Datapalooza, which takes place from May 31 to June 3 at the Marriott Wardman Park Hotel, close to public transportation.

This event is open to the public and has many booths displaying innovative apps.
