About peg
PEG office of landscape + architecture is an award-winning design and research office based in Philadelphia, PA, led by Karen M’Closkey and Keith VanDerSys. Their work is recognized for the creative exploration of emerging media, focusing specifically on how new modeling software and the increased accessibility of geospatial technologies provide opportunities to access new kinds of patterns and, therefore, new ways of designing and understanding landscapes and our place within them.
Interpretations of nature, environments, and landscapes involve various technologies and practices that connect the material world with representations. These interpretations encompass symbolic representations, such as geometry and form; behavioral models of processes, including numeric models and simulations; and Earth surface representations like maps and classifications. PEG’s work in these areas has been recognized through publication in 60 design books and magazines and numerous competitions and awards, including the prestigious Architectural League Prize for Young Architects and Designers and a PEW Fellowship in the Arts. Their work has been showcased in 20 exhibitions and, most recently, received a World Landscape Architecture Award (2021) and three National American Society of Landscape Architects Awards (2019, 2020, 2025), the latter for their work as EMLab.
M’Closkey and VanDerSys are guest editors of LA+ GEO (2020) and LA+ SIMULATION (2016), and authors of Dynamic Patterns: Visualizing Landscapes in a Digital Age (2017). They are curators of two symposia—Instruments of Change” (2022) and “Simulating Natures” (2015). Their latest book, Media Matters in Landscape Architecture, includes 14 chapters written by contributors from various fields discussing the material and technical aspects of environmental media and their interrelationships.
