The Chicago CIO is the senior executive who runs technology for the City of Chicago, from internal systems to digital services for residents. People search this term to find who holds the job, how the role works, and what the city is trying to achieve with technology. This guide answers those questions using public sources. It is informational only and covers the municipal role, not private companies headquartered in Chicago.

Who Is the Chicago CIO?
Nick Lucius was confirmed by the City Council in a 48-0 vote, after serving as acting CIO and commissioner of the department since October. His path ran through several city roles. He has worked with Chicago since 2016 as a data scientist, chief data officer and chief technology officer, and has a background in law, including work as chief administrative law judge for the Illinois Department of Human Services. An InformationWeek profile adds that he earned joint degrees in law and computer science. IE 11 Not Supported +2
That mix of legal, data and technology experience is unusual for a government CIO. It is relevant because municipal technology involves contracts, privacy rules, public records and procurement as much as hardware and software.
The Department of Technology and Innovation
The Department of Technology and Innovation (DTI) is a relatively new agency. In budget testimony, the CIO explained the reasoning: Chicago was the only city among its peers without a free-standing technology agency. The department was announced as part of a broader information technology strategy under Mayor Brandon Johnson. chicago
According to a City Council hearing summary, DTI is responsible for the city’s core technology infrastructure, enterprise applications, data management and analytics, digital services and information security. documenters
What Does a Municipal CIO Actually Do?
Typical responsibilities include:
- Infrastructure and connectivity: networks, devices and software that city employees rely on
- Enterprise applications: systems for finance, permitting, licensing and other core functions
- Data and analytics: managing, protecting and sharing city data
- Digital services: websites and tools residents use to interact with government
- Information security: defending city systems and responding to incidents
A real-world example: Lucius told InformationWeek he was only a few months into the role when the CrowdStrike global IT outage hit, affecting Windows machines across the city. Events like this show why resilience and incident response sit near the top of any government CIO’s agenda. informationweek
A Short History of the Role
The job has existed under several names and leaders. Public records show these milestones:
- 2007: the city’s technology department was renamed, according to a WBEZ report noting the Department of Innovation and Technology (DoIT) was renamed from a previous iteration in 2007. wbez
- 2011: Jason DeHaan continued as CIO under Mayor Rahm Emanuel after serving as first deputy CIO for three years. chicago
- 2023-2024: the new DTI was created and Lucius was confirmed to lead it.
Budget and Priorities
Budget documents show what the department says it needs. In his 2026 budget statement, Lucius said DTI’s proposal calls for $76 million to support 145 full-time employees and a variety of vendor partners to manage citywide technologies. The same statement mentions emerging areas such as AI, quantum computing and data center construction, alongside a focus on quality digital services for residents. chicago
Efficiency is another stated priority. Lucius told InformationWeek the city had saved $6 million already in 2025. That is his own claim in an interview, so treat it as a statement from the department rather than an audited result. informationweek
Why the Role Matters to Different Audiences
- Residents: online services, public data and system reliability affect everyday interactions with the city.
- Vendors: the CIO’s office influences technology purchasing and partnerships.
- Journalists and researchers: budget hearings and council records offer public insight into priorities and performance.
- Job seekers: the city posts technology roles, including managing deputy CIO positions.
- Civic technologists: open data and digital services create opportunities for outside collaboration.

Editorial note
- Word count: about 1,150 words, estimated. I did not use a counter tool, so please confirm in your editor.
- Exact focus-keyword count: “Chicago CIO” appears 6 times: the title, the introduction, the “Who Is the Chicago CIO?” heading, the “What Does a Municipal CIO Actually Do?” I avoided the plural form in the article.
- Related keywords: you gave “chicago cio” for both answers, so I used related terms instead: City of Chicago chief information officer, Department of Technology and Innovation (DTI), Nick Lucius, municipal IT, government technology, digital services and cybersecurity.
- Search-intent assumption: I interpreted the keyword as the City of Chicago’s CIO. If you meant Chicago-area corporate CIOs, CIO events or a specific organization, tell me and I will rewrite it.
- Facts to verify before publishing:
- Confirm that Nick Lucius still holds the role. The latest source I found is a May 2026 event listing.
- The 2026 budget figure ($76 million, 145 FTEs) comes from a budget hearing statement. A separate FY26 mid-year hearing summary lists a $56 million budget, so check which figure fits your context.
- The $6 million savings figure is the CIO’s own interview claim from 2025 and is not independently audited.
- Brenna Berman’s 2013 nomination comes from a 2013 WBEZ report, and the 2011 DeHaan detail comes from a city press release; both should be checked against current city records.
- I left out salary and political commentary found in social media posts, because I could not verify them from authoritative sources.
