Career Narrative
I’ve long been intrigued by purposeful approaches to places and landscape networks that are attuned to their local contexts while being inclusive, convivial, resiliently adaptive and biodiverse.
I started out in professional practice: 3 years with the multi-disciplinary AE firm of Totten Sims Hubicki Associates, and +5 years with the well-known Toronto-based environmental design firm of Hough Stansbury Woodland. Particularly formative was my work with HSW principals/mentors Michael Hough and Jim Stansbury. Daily practice was guided by first principles, critical contextual research, interdisciplinarity, and inclusive and reflective design through time.
HSW was the go-to Canadian firm for ground-breaking, novel and trans-disciplinary assignments. For instance, Michael Hough and I led two major urban regeneration projects (Don River Restoration, Toronto Brickworks) that were named "Most significant and influential landscape architectural projects, decade 1988-1998” (Ontario Association of Landscape Architects, Ground, vol. 43)—two of only 4 projects that were so honored. Jim Stansbury and I led on the Massasauga Provincial Park management plan for a 130 sq. km. Precambrian Shield archipelago set in the sublime Georgian Bay—since designated a Category II Protected Area by the International Union for Conservation of Nature. And I was primary author/designer on the inaugural plan for what would become Toronto's Rouge National Urban Park. With 79 sq. km. of committed land, this unique park is the largest of its emerging type in North America.
My appointment at Penn State in 1993 provided an opportunity to focus on several linked themes that seemed underdeveloped in the academy: the interplay between environmental design and the synthetic ecologies (landscape ecology, restoration ecology, conservation biology) and socially inclusive green urban/community design that welcomes the empowered and mingled imaginations of all stakeholders—generating the landscape insights that precede good design.
My interest in regenerative urban ecosystems was reinforced while collaborating with Carnegie Mellon University colleagues on Pittsburgh's Nine Mile Run (1996-2000), a seminal implemented stream restoration and valleyland brownfield reclamation project.
Much of my work has involved exploring idea spaces between fields—John Elder calls them “dangerous ecotones”—with scholars and practitioners in the natural and social sciences, humanities, education and the arts. I've collaborated with Monica Schlee (2000-2012) on environmental quality in Rio's favellas; PSU learning science colleagues on the Mountain Project in south Asia (2005-2010); geographers, climate scientists and education faculty (2008-2012) on our NSF-funded ALCCAR Project in Ghana and Tanzania; and various European associates (2010-present) on my convivial greenstreets work. My role as designer/applied ecologist has addressed climate change and globalization impacts at regional and local scales, while striving for local-level place identity, sustainabilty, resilience, and equity. As often as we could, we sought strategic learning and action not just for, but in and especially with underserved communities.
