[2] She studied applied mathematics at Harvey Mudd College, then moved to the University of California, Berkeley for her graduate degrees, where she specialized in civil and environmental engineering.

[citation needed] Her doctoral research considered the characterization of indoor air pollutants generated by people inside buildings.

[3] Miller moved to the University of Colorado Boulder, where she was made a Chancellor's Postdoctoral Fellow and she studied air quality in schools and in communities.

She has studied how filtration and germicidal irradiation impact indoor air quality, and how to optimize the design of such systems to maximize the benefits to human health.

She has developed characterization techniques to understand indoor environmental quality inside homes and how heating, ventilation, and air conditioning (HVAC) impacts the transmission of infectious diseases.
