Schulman co-founded HEET in 2008. A lover of maps, she created the first-in-the-nation statewide zoomable public map of utility-reported gas leaks. Through her co-leadership of the FixOurPipes.org study, she helped municipalities coordinate with utilities to find solutions to fix gas leaks faster and at less expense. She started the Large Volume Leak Study, which discovered a way for gas utilities to identify super-emitting gas leaks and repair them. Together with Zeyneb Magavi, she has developed HEET’s innovative solution to transition gas utilities from gas to networked geothermal, or systems of networked ground source heat pumps. There are several gas utilities now installing thermal networks in Massachusetts and New York. Schulman is also the author of six novels, which have been translated into 12 languages and reviewed by The New Yorker, The Economist and CNN.
