Justin is a 4th year PhD student in sustainable development at Columbia University with a background in chemical engineering, organic chemistry, and material science. He worked for a decade in academia and in industry with fuel cells and lithium batteries before venturing into the world of social science. He also has a handful of patents in medicinal chemistry from over a decade ago when he lived in Copenhagen and worked for a small pharmaceutical start-up. These days, he tries to keep faith with the scientist in himself and looks for projects at the interface of energy, environment, and economics. He has studied electricity peak-shifting and environmental externalities induced by residential smart meters and career concerns in the natural gas markets. He is also an avid gardener and is trying to sustain a monarch butterfly population in his parents' backyard in Maryland.
