Evan Thomas is the Director of the Mortenson Center in Global Engineering and the Global Engineering Residential Academic Program, and the CU Boulder Climate Innovation Collaboratory, and holds the Mortenson Endowed Chair in Global Engineering at the University of Colorado at Boulder. He is a tenured full Professor jointly appointed in the Civil, Environmental and Architectural Engineering and the Aerospace Engineering Sciences Departments, and an affiliate faculty in Environmental and Occupational Health at the Colorado School of Public Health. Evan is currently a member of the NASA and USAID SERVIR Applied Sciences Team, a member of the board of the Millennium Water Alliance, and Co-Chair of the ASME Engineering for Global Development Research Committee. 

Evan has a PhD in Aerospace Engineering Sciences from the University of Colorado at Boulder, is a registered Professional Engineer, and has a Masters in Public Health from the Oregon Health and Science University. 

Evan’s technical background is in water and air testing and treatment applied in developing communities through to operational spacecraft. He founded SweetSense Inc. which is supported by USAID and the National Science Foundation to develop and apply satellite connected sensors monitoring drinking water services. Daily, the team is monitoring millions of people’s water supplies across east Africa.

Evan’s research has been funded by NASA, the National Science Foundation, the World Bank, USAID, the UN Foundation, the CDC, the United Kingdom Department for International Development, the Gates Foundation, and others.

As Chief Operating Officer of DelAgua Health from 2012-2016, Evan conceived, designed and directed a $25 million dollar public health intervention in Rwanda with the Government of Rwanda. The program reached 350,000 households with cookstoves and 102,000 households with water filters, in over 7,500 villages and 1.6 million people. 

Evan was previously an Associate Professor at Portland State University and Oregon Health & Science University from 2010-2018 (asst prof. 2010-2016) founder of the SweetLab, and founding director of GlobalPDX. 

Evan was a civil servant at the NASA-Johnson Space Center in Houston, Texas from 2004-2010. At NASA, Evan was a aerospace engineer working on microgravity fluid management technologies and water recovery systems for spacecraft hardware flying on the Space Shuttle and International Space Station.
