Our People


Audrey Schulman, HEET Co-founder and Co-Executive Director

Audrey co-founded and has helped lead HEET since its start in 2008, creating its innovative science-based orientation in the fields of energy efficiency, solar and gas leaks. She used utility-reported data to create HEET’s public zoomable natural gas leak maps (the first in the country). She started the Large Volume Leak Study, which determined a way to identify super-emitting gas leaks so the utilities could repair them. Schulman is also the author of five novels, which have been translated into 12 languages, and reviewed by the New Yorker, The Economist and CNN.

Zeyneb Magavi, Co-Executive Director

Zeyneb is currently focused on transitioning the natural gas distribution system to a geothermal energy distribution system using the GeoMicroDistrict concept. The next step is to pilot in a neighborhood in MA, together with the state’s largest gas utilities. Zeyneb previously led HEET’s Large Volume Leak Study, which developed a method to rapidly cut emissions from leaking gas pipes in half.  She has worked at BBN Technologies, Harvard University, and in multiple startups.  She is committed to creating and driving forward just and wise solutions to the urgent challenge of climate change through multi-disciplinary problem solving, co-creation, and innovation.

Molly Fairchild, Director

Before receiving a Master of Science in International Nutrition from Cornell, Molly was a Peace Corps Nutrition Project Coordinator with the Thai Ministry of Health, implementing and adapting a growth monitoring program for children, at the village level. As a research associate at Dianon Systems, she developed case studies on chronic lyme disease and mapped the incidence throughout the United States.  As a researcher for a domestic violence program for women on the Navajo Reservation, she developed a record system to support grant writing and research. More recently, she helped to start the conversation with local officials about energy use, co-authoring the Sustainability Plan for the town of Wellesley. As the staff-coordinator for Wellesley’s Sustainable Energy Committee she developed the Greenhouse Gas Emissions Inventory for residential, commercial, municipal and transportation sectors, establishing the baseline and first-five years of monitoring, to guide the town’s goals for emissions reduction.  An experienced perennial gardener, with a passion for native plants, Molly respects the delicate environmental balance that sustains living things.

Dominic Nicholas, Director

Dominic Nicholas

Dominic joined HEET in 2018 and is focused on finding and fixing super-emitting methane leaks. He leads the work on HEET’s 5 year commitment to the shared action plan, providing an independent watchdog and verification role of gas utilities progress in finding and fixing super-emitting gas leaks. He led both the trial year and year 1 studies and currently leads the year 2 study. In 2019 he led a new study exploring how super-emitting leaks may evolve over time. Dom created a new HEET gas leaks mapping process that enables the sharing of geocoded gas leaks and pipeline replacement plans, together with a new creative commons HEET library. Dom is working with Massachusetts towns and researchers to gain further environmental impact from this shared data. He is a co-author of the recently published Repair Failures Call for New Policies to Tackle Leaky Natural Gas Distribution Systems paper, and has been a visiting researcher at Boston University, studying leaked methane diffusion in soils. He has years of gas leak surveying experience using the leak extent method, cavity ring down spectrometer and chambering methods. Prior to HEET, Dom has a long career in technology and startups, the pinnacle of which was leading a team of 12 engineers working on utility scale solar farm monitoring systems. Dom has certificates in both Management Excellence and Social Impact Measurement. He has a multidisciplinary background including science, technology and art and received his Masters in Mathematics and Computing from the University of Essex, England. He lives with his wife Joanna Messing and son in Brookline, MA.

Jason Taylor

Jason Taylor has been training green job workers for the last 12 years at the Green Jobs Academy, the ABCD Weatherization Lab in Mattapan and at Roxbury Community College. He has written air-sealing curricula for community colleges, MassCAP and HEET. He has presented new and old air-sealing techniques for NESEA/Boston, NESEA/New York, the Department of Energy and the Studio for High Performance Design and Construction (SHPDC).

Jason began as a volunteer at HEET, arriving at the first weatherization barnraising in dirty overalls and was immediately made a team leader weatherizing windows. (Perhaps this is the reason he is often seen wearing dirty overalls.)

Jason currently trains 12-18 MassSAVE weatherization crew chiefs each month as well as continuing to work for Byggmeister Associates as their air barrier specialist. He also has participated in the air barrier fine-tuning of many Net Zero Retrofits and Passive Houses. He has developed training techniques that are extremely successful with people that dislike classrooms and hopes to become a trainer of the trainers in the near future as green jobs training programs are pushed up to the next level.
