After her PhD, Gast spent a
postdoctoral year completing a
NATO fellowship at the École Supérieure de Physique et de Chimie Industrielles in Paris. From 1985 to 2001, she taught at
Stanford University, and then moved to the
Massachusetts Institute of Technology, where she served as the vice president for research and associate
provost until her appointment as
Lehigh University president in 2006. a classic textbook on colloid and surface phenomena, and has presented named lectures at several of the nation's leading research institutions.
Presidency of Imperial College London Gast was named president of Imperial College London on 3 January 2014, taking up post on 1 September 2014. She succeeded
Keith O'Nions. As president, Gast led the college's strategy, including the development of its new 25-acre campus, Imperial West, and its links to government, industry, philanthropists and alumni. In September 2021,
Hugh Brady was announced as Gast's successor at Imperial College London. He took up his post in August 2022.
President-and-provost leadership model In April 2012 Imperial's governing council agreed to separate into two the role of the rector (the head of the university), and create the senior positions of president and provost. The role of president gives emphasis to Imperial's relationships with government, industry, philanthropists and alumni and enhances the college's ability to influence in the UK and overseas. The provost is responsible for delivering and enhancing the college's academic mission in education, research and the translation of research results into practical outcomes. The president-and-provost model is common at many other world-leading universities, including MIT, Caltech, Yale and Harvard. When the transition to the new model and the search for its new senior positions began in 2012, the title changed to president & rector. Once the provost had been appointed and the transition was complete, Gast was known as president & rector.
Presidency of Lehigh University From August 2006 to August 2014, Gast was the 13th president of Lehigh University. Gast is not the first Lehigh president recruited from MIT. In 1895 they invited
Thomas Messinger Drown to take the presidency, for whom Drown Hall is named. at an Earth Day celebration. The Climate Commitment will create institutional policies and procedures to manage the development and implementation of a university-wide plan that affirms Lehigh's commitment to protect and improve the environment through its teaching, research, faculty, student and staff service, and administrative operations. In signing the Climate Commitment, Gast said that safeguarding the environment is an issue the Lehigh community aggressively embraces.
Lord Dearing Memorial Conference In 2010, Gast shared her educational expertise at the Lord Dearing Memorial Conference, a forum for accomplished educators to shape the debate on the future of education. Gast presented in a session discussing the global economic crisis and higher education.
Appointment as a U.S. science envoy In 2010, Gast was selected as one of three new science envoys by
Secretary of State Hillary Clinton. Gast was charged with encouraging U.S. global engagement in science and technology. She has traveled to the Central Asian and Caucasus regions, including Kazakhstan,
Professional associations and committee memberships Gast served on a number of national advisory committees and boards, including the board of the
American Association for the Advancement of Science (AAAS), was a member of the Academic Research Council for the Singapore Ministry of Education and the National Research Council Committee for Science, Technology, and the Law. She was a member of AAAS, the
American Chemical Society, the
American Institute of Chemical Engineers, and the
American Physical Society. In October 2012, Gast was elected to the board of directors of the
Chevron Corporation, one of the world's leading integrated energy companies, with subsidiaries that conduct business worldwide. Gast served on the company's audit committee. John Watson, chairman of Chevron Corporation, said "Dr. Gast has tremendous technical and industry expertise that will be a valuable addition to our board discussions. We look forward to welcoming her to the board." Gast was a member of the U.S. Manufacturing Competitiveness Initiative Steering Committee. in 2011, she joined other national leaders in Washington, D.C. for the 25th anniversary of the Council on Competitiveness, a day marked by the public release of the council's long-awaited strategy to improve American competitiveness and spur economic recovery through increased manufacturing. and was also a member of the advisory board for the World Economic Forum Centre for the Fourth Industrial Revolution.
"Science and Security in a Post 911 World" report In 2006, Gast co-chaired (with
Jacques Gansler, vice president for research at the University of Maryland, a non-partisan committee that produced an extensive report on "Science and Security in a Post 9/11 World: A Report Based on Regional Discussions Between the Science and Security Communities Committee on a New Government" (University Partnership for Science and Security) that was published by the National Academy of Sciences. Gast and Gansler co-authored an op-ed in the July 11, 2008 issue of the
Chronicle of Higher Education, citing a concern that the unintended effects of restrictive federal government policies on scientific research include impeding the nation's ability to be economically competitive and defend itself against potential threats. They wrote: "It's time for researchers and intelligence officials to work together and devise policies that strike the appropriate balance between science and security. Toward that end, our committee recommends that the federal government establish a standing entity, preferably a high-level Science and Security Commission chaired by the national-security adviser and the director of the White House's Office of Science and Technology Policy."
Shovel-ready science? In March 2009, Gast authored an op-ed that appeared in
Science magazine, in which she sounded a note of caution in the way that the short-term funding for scientific research contained in the U.S. economic stimulus package will be spent. "Transformative change requires long-term investment in the nation's intellectual infrastructure," she wrote. '
Shovel ready' makes sense for getting people to work on deferred infrastructure needs, but how does it relate to the scientific research and education programs needed to address the many challenges looming before us?" Long-term research and education provide innovative, creative discoveries that spur transformative change, Gast noted. "The United States needs to start making the down payment on this exploration, knowing that the needed breakthroughs cannot be generated within the next two years. As science funding agencies begin awarding their one-time money, they must be mindful of the sustainability of their programs. The recent signing of the fiscal year 2009 omnibus bill with its 4.7% increase for agencies funding science and technology R&D is a welcome sign. Maintaining that momentum in the coming years will be essential." ==Controversies==
