Innovation and Technology


Danielle DuMerer, CIO & Commissioner

  • 312.742.1221

Danielle is CIO and Commissioner of the City of Chicago's Department of Innovation and Technology (DoIT), where the team is working to improve how residents interact with government by creating more responsive and accessible digital services. DoIT is responsible for the City’s core technology infrastructure, enterprise applications, data management & analytics, and information security; DoIT partners with other City departments to leverage data and technology to improve operations and service delivery.

Danielle brings more than ten years experience in government tech, having previously served as the City’s CTO and leading data, digital inclusion, and other strategic initiatives. She was named one of Government Technology's Top 25 Doers, Dreamers, and Drivers in 2019. In 2018, Bloomberg Cities named Commissioner DuMerer one of seven CityLab innovators to watch, and Statescoop named her one of the Top Women in Technology. In 2016, Danielle and her team were recognized by the Chicago chapters of SIM and AITP as the Most Effective IT Team in a large company. Prior to joining government, Danielle developed educational technology products at the McGraw-Hill Companies. She also worked in the Library and Archives field—serving educational and non-profit organizations to promote equitable access to and preservation of information resources. Danielle holds a Master of Library and Information Science degree from the University of Maryland, College Park and a Bachelor of Arts from the University of Illinois, Urbana-Champaign.

Under Commissioner DuMerer’s leadership, DoIT has been leading the charge to modernize the City’s 311 non-emergency management system. The 311 system is the heart of City operations and has been redesigned with Chicago residents and City staff to improve engagement and service delivery. The new system provides multiple ways to interact with the City—phone, web, text, social media, and the City’s first official mobile app—and an improved customer experience that tracks work transparently through streamlined processes.

DoIT has also launched the Chicago Design System—a guide to producing delightful services and technology applications for employees and residents—and, in partnership with the Mayor’s Office for People with Disabilities, led Chicago in becoming the first city in the world to pilot the Smart City Digital Inclusion Maturity Model. The Model aims to help city leaders and urban planners empower people with disabilities through technology.

In 2018, DoIT was selected as a partner with Infinity Math, Science and Technology High School, a CPS STEM school, in Little Village, providing mentorship and other support to its students. Chicago won a Smart 50 Award from Smart Cities Connect for its innovative Array of Things program, and was recognized with a Smart Community Award by the Intelligent Communities Forum. The Chicago Department of Public Health and DoIT also received the Milbank Memorial Fund and Academy Health State and Local Innovation Award for the City’s Lead Safe program—a program that predicts and helps hospitals intervene when toddlers may have elevated lead levels.
