the top 30 (ranking 28th in 2022) amongst universities worldwide. Carnegie Mellon is distinct in its interdisciplinary approach to research and education. Through the establishment of programs and centers that are outside the limitations of departments or colleges, the university has established leadership in fields such as computational finance, information systems, cognitive sciences, management, arts management, product design, behavioral economics, energy science and economics, human–computer interaction, entertainment technology, and decision science. Within the past two decades, the university has built a new university center (Cohon University Center), theater and drama building (Purnell Center for the Arts), business school building (Tepper School of Business), and several dormitories. Baker Hall was renovated in the early 2000s (decade), and new chemistry labs were established in Doherty Hall soon after. Several computer science buildings, such as Newell Simon Hall, also were established, renovated or renamed in the early 2000s. The Gates Hillman Complex, opened for occupancy on August 11, 2009, sits on a site on the university's West Campus, surrounded by Cyert Hall, the Purnell Center for the Arts, Doherty Hall, Newell-Simon Hall, Smith Hall, Hamburg Hall and the Robert Mehrabian Collaborative Innovation Center. It contains 318 offices as well as labs, computer clusters, lecture halls, classrooms and a 255-seat auditorium. The Gates Hillman Complex was made possible by a $20 million lead gift from the Bill & Melinda Gates Foundation and an additional $10 million grant from the Henry L. Hillman Foundation. The Gates Hillman Complex and the Purnell Center for the Arts are connected by the Randy Pausch Memorial Footbridge. On April 15, 1997, Jared L.

During Cohon's presidency, Carnegie Mellon continued its trajectory of innovation and growth. His strategic plan aimed to leverage the university's strengths to benefit society in the areas of biotechnology and life sciences, information and security technology, environmental science and practices, the fine arts and humanities, and business and public policy. In 2006, following negotiations between President Cohon and South Australian Premier Mike Rann, CMU opened a campus of the Heinz College in the historic Torrens Building in Adelaide, Australia. President Cohon's term ended on June 30, 2013, after which he returned to the faculty at Carnegie Mellon.
