Meredith is an adjunct senior research fellow with the RISE project in Architecture at MADA. She first joined Monash University in February 2010 as a research fellow within the Urban Water Governance (later known as Urban Water Transitions and Governance) program within the School of Geography and Environmental Science and Centre for Water Sensitive Cities (now Monash Water for Liveability Centre). She moved to the School of Social Sciences in January 2014, where she continued to conduct research into aspects of water sensitive urban design and landscape perception, until December 2015. From January 2016 to September 2017, she was an adjunct lecturer in Human Geography in that school.

Meredith has a diverse background, both academically and professionally. After completing an Honours Science degree at the University of Melbourne, majoring in Botany, in which she received an Exhibition, she joined CSIRO as journal editor for the Australian Journal of Marine and Freshwater Research. In addition, she edited the book Limnology in Australia, which received a commendation in the Whitley Awards in 1986. Meredith then completed a Master of Landscape Architecture, again at the University of Melbourne, receiving the Ellis Stones Award for her minor-thesis research on landscape aesthetics.

She worked as a landscape architect in private practice, on residential, commercial and civic projects, for some years before undertaking a PhD in landscape perception at the University of Melbourne. Her thesis was titled 'Public Perceptions of Victorian Freshwater Wetlands: Preference, Health and Cultural Sustainability'. This varied experience informed Meredith's research activities within the Urban Water Transitions and Governance program. As part of Project 6 (Society and Institutions) within the Cities as Water Supply Catchments program of the Centre for Water Sensitive Cities, she investigated the risk perceptions of Australian urban water practitioners towards decentralised water systems, in a research collaboration with CSIRO in its "Water for a Healthy Country" National Research Flagship. She completed a research project within the CRC for Water Sensitive Cities, exploring community receptivity towards the retrofit of green infrastructure in Australian cities. The project specifically looked at community perceptions of raingardens. Her research interests include the perception of watery issues, water sensitive urban design, landscape aesthetics and landscape-related topics at the intersection of nature and culture.
