Hollander studies how cities and regions manage physical change during periods of growth and decline and the cognitive, health, and social dimensions of community well-being. He has made a significant impact on the urban planning field, as evidenced by his election to serve on the Governing Board of the Association of Collegiate Schools of Planning (the US national organization of urban planning academics) and his appointment to the editorial boards of two high-impact internationally renowned urban planning journals, Planning Practice & Research and the Journal of Planning Education and Research His book Cognitive Architecture won the Environmental Design Research Association national research award. He seeks to redefine the conventional models for measuring success in urban planning (e.g. population, employment, or income growth), drawing on research in computer science, psychology, and landscape architecture.
He has made notable contributions to both empirical and theoretical advancements in understanding community change and what planning and policy responses can accomplish.
