Greg Mello is a founder and Executive Director of the Los Alamos Study Group and has led its varied activities since 1992, including policy research, environmental analysis, congressional education and lobbying, community organizing, litigation (FOIA, civil rights, NEPA), advertising, and the nuts and bolts of funding and running a small nonprofit. From time to time he has served as a consulting analyst, writer, and spokesperson for other nuclear policy organizations. Greg was educated as a systems engineer with a broad scientific background (Harvey Mudd College, 1971, with distinction) and as a regional planner with emphases in environmental planning and regional economics (Harvard, 1975, with distinction, HUD Fellow in Urban Studies). During the early 1980s Greg was a high school science and math teacher, then a hazardous waste inspector and statewide hazardous materials incident commander, and in the late 1980s a supervising hydrogeologist, for the New Mexico Environment Department. In 1984 Greg led the first regulatory enforcement at Los Alamos National Laboratory (LANL). In the early 1990s Greg was a consulting hydrologist in parallel with the early Study Group, with cleanup projects in New Mexico and California. In 2002, Greg was a Visiting Research Fellow at Princeton University’s Program on Science and Global Security. Greg’s research, analysis, and opinions have been published in the New York Times, Washington Post, The Bulletin of the Atomic Scientists, Issues in Science and Technology, in the New Mexico press, and elsewhere. He has been interviewed thousands of times by U.S. and international news media (print, radio, and television). Greg’s research has been the source or impetus of many of these media articles and programs. In addition to speaking at hundreds of public meetings and events in New Mexico, Greg has been a guest speaker at several international disarmament events here and abroad.
