Timothy Lawrence Johnson

Associate Professor of the Practice in Energy and the Environment

Chair, EE Program

Primary Appointment

Earth & Ocean Sciences Division

My teaching and research address topics at the intersection of energy system planning, design of the built environment, and natural resource management, with a particular interest in how we can leverage interactions among these areas to improve environmental quality and human health. This work is inherently interdisciplinary, requiring an understanding of current and emerging energy resources, technologies, and patterns of end-use demand, as well as the demographic, economic, and policy factors driving change across the energy system. Pursuit of these interests has relied on close collaborations with other researchers, including agricultural production economists, ecologists, planners, and engineers. Current activities involve studies of how the built environment impacts energy consumption and the analytical needs of regional energy planning.
