The CAIOs Leading Responsible AI Development Across Government

Federal agencies are appointing new chief artificial intelligence officers as part of the collective movement to meet directives set forth from the White House’s AI executive order that tasked agencies with a series of responsibilities connected to the emerging technology.

Although artificial intelligence development in the federal government is not new, this marks the first time federal agencies are all mandated to appoint a designated CAIO, whose responsibilities include “coordinating their agency’s use of AI, promoting AI innovation, [and] managing risks from the use of AI,” according to OMB guidance on AI governance.

Some agencies, like the departments of Defense, Health and Human Services and Veterans Affairs, have had AI chiefs in place already comprising various forms of the CAIO title.

Here are some of the most prominent leaders at the agency level in charge of AI.

Agriculture Department

USDA Chief Data and AI Officer Chris Alvares is responsible for “developing strategies that enable USDA to fully leverage its data as a strategic asset, improving organizational decision-making and outcomes for citizens.”

Alvares began his career working for private-sector biotech companies before becoming director of a data analytics team that provided genomic analytics services to other biotechnology and pharmaceutical clients.

Alvares joined USDA’s Food Safety and Inspection Service (FSIS) in 2008 as a data analyst, where he built the analytics office from five to more than 20 staff members. Alvares became deputy CDO in 2019 where he has been working to modernize data analytics within USDA.

Commerce Department

Ryan Higgins became the Commerce Department’s CAIO Jan. 1. Higgins also serves as the department’s acting CIO.

Previously, Higgins served as Commerce’s CISO and deputy CIO, helping to establish policies and processes, developing DOC compliance with the Federal Information Security Modernization Act (FISMA) of 2014 and coordinating cyber incident response.

Prior to joining Commerce, Higgins held a variety of roles within the U.S. Trustee Program, Justice Department and Department of Homeland Security.
