Past Masters Students

Lucy

Lucy Cheadle

Lucy Cheadle completed her master's in environmental engineering in the air quality track. She received her BS from Washington University in St. Louis in chemical engineering and is originally from Seattle, Washington. Her research focused on the small scale spatial variability of ozone in Boulder and in addition she was involved with coordinating the AQIQ program. When she’s not in the lab, Lucy loves running around in circles as fast...
Katya

Katya Hafich

Katya is a recovering biogeochemist, who worked at CU in two capacities as the Education and Outreach Coordinator for the AirWaterGas Sustainability Research Network, and as the program coordinator of the Learn More About Climate initiative at the Office for Outreach and Engagement. She focused on developing and sharing resources to translate science research into meaningful tools for public engagement and on building mutually beneficial partnerships between Colorado communities and...
Elise

Elise Mesenbring

Elise Mesenbring was a graduate student in the Mechanical Engineering department at CU Boulder. She grew up near Minneapolis, Minnesota and decided to continue braving those arctic winters while obtaining her BA in Physics and Mathematics at Gustavus Adolphus College in Saint Peter, MN. When Elise started at CU, she worked on the group’s previous cookstove project, REACCTING, and then transitioned to the P3 project. In her spare time, Elise...
Kira

Kira Sadighi

Kira Sadighi completed her masters in the Environment and Energy track. She joined the lab in 2014 and worked on the LA Ozone project, South Boulder Creek project, and some community-based projects. When she’s not studying air quality, Kira enjoys hiking, backpacking, and sewing.

Past PhD Students

Joanna

Joanna Casey

Joanna Casey is generally curious and enjoys learning about our planet’s atmosphere and its interfaces with human exploits. She is interested in air on scales ranging from the small volumes of molecules enclosed by the walls of our homes, to community and regional scale airsheds, on up to the global scale atmosphere and how its constituents interact with the earth system. As a PhD student, she utilized emerging low-cost sensor...
Ashley

Ashley Collier-Oxandale

Ashley Collier-Oxandale completed her PhD in Environmental Engineering at CU in 2018. She had been working with this lab since 2011. Her work focused on air quality sensor quantification and research applications. For example, one of her projects involved using a low-cost sensor network to examine the spatial variability of methane and non-methane hydrocarbons at the neighborhood scale in order to better understand potential exposures for the residents of that...
Kyle

Kyle Karber

Kyle Karber was a Mechanical Engineering PhD student at the University of Colorado Boulder. He is interested in renewable energy in developing communities – specifically the drivers and barriers to adoption of small scale solar lighting products as replacements for smoky kerosene lamps. Why aren’t more off-grid households using solar products which are cleaner, brighter, money-saving, and locally available? Kyle spent 8 months in The Arusha and Kilimanjaro regions of...
Ricardo

Ricardo Piedrahita

Ricardo Piedrahita completed his PhD in Mechanical Engineering at the University of Colorado Boulder. His research focused on low-cost air quality monitoring, cookstove adoption, and exposure assessment. This included REACCTING, a project in Northern Ghana performing personal, microenvironmental, and regional air quality measurements as part of a cookstove intervention study. In addition to cookstove research, he is interested in quantification and uncertainty estimation for low cost air quality sensors, as...

Past Undergraduate Students

Rachel

Rachel Moore

Rachel has a Bachelor's of Science in Applied Mathematics from CU Boulder. She worked on several projects during her time in the Hannigan Lab but contributed mostly to the REACCTING project. She executed data analysis on GPS and particulate matter data collected from homes in Ghana. In addition to her work on the REACCTING project, she was the TA for the Hannigan Lab's outreach program, AQ-IQ. Rachel left the lab...
