Madison Burns, Undergraduate Researcher

Madison is a 3rd year undergraduate student in the Landscape Architecture program at UC Davis. As a designer in this era of climate change, she aims to take part in reimagining unsustainable landscaping standards. Madison believes California native plants are a vital piece to this puzzle and has led efforts to incorporate native landscaping in the Davis area. She also has experience collecting data pertaining to drought and plant health through her internship with UC Davis’s Smart Landscape Program. She hopes to contribute these skills and her passion for climate resilient landscaping to the USDA-FS residential fire project. 


Priscilla Maldonado, Undergraduate Researcher 

As a 4th year undergraduate student at UC Davis, I am pursuing a landscape architect degree. Due to my passion for environmental design, I am interested in flood resilient planning and fire defense design. Initially, I was solely focused on flood resilient planning, because I did not believe landscape design could mitigate the destruction of wildfires. However, learning about fire defense design changed my perspective from vegetation fueling wildfires, to vegetation slowing wildfires and potentially saving lives. By surveying post-wildfire sites and finding suitable drought-preventative vegetation, I hope to sway public opinion that landscape design can save lives.


Kelly Graziadei, Undergraduate Researcher & 2022 McNair Scholar

Kelly is a Sustainable Agriculture and Food Systems Major student working on a FFAR-funded project on the climate resilience of urban tree crops across the US, and the taxonomic and nutritional diversity of urban forests.

 Alex Berk, MSc student (EPM)  

Danelia Robinson (PhD student co-supervised with D/Prof Leishman, Macquarie University, Sydney, Australia)

Dani Robinson is a First Nations Kamilaroi Aboriginal woman. She is undertaking research into greenspace governance, environmental law, urban greening and development. Her research project reviews the success of governance models and the legal frameworks used by government and developers to balance urban growth with the long-term aspirations for adequate greenspace and healthy urban precincts. Dani has a strong interest in green space as a means by which Indigenous cultural heritage can be conserved and understands the importance of preserving cultural heritage landscapes for future generations to learn and appreciate the unique attributes of Aboriginal or First Nations culture. She is also researching the governance processes by which Indigenous traditional knowledge regarding land and land use can inform future urban development. Dani has an extensive work history, having worked on developing large complex water-based infrastructure, land management and rehabilitation projects, planning and implementation of urban/residential masterplans, and government approvals.
