Francis McMichaelPh.D. (Civil Engineering, Minor in Geophysics) 1963, California Institute of Technology
  • M.S. (Geophysics) 1959, California Institute of Technology
  • B.S. (Mining Engineering) 1958, Lehigh University

  • Carnegie Mellon, 1967-2002

Professor McMichael has worked extensively on applying material and energy-balance approaches to the study of environmental problems. In recent work he has applied concurrent engineering concepts to the design of products and processes to mitigate environmental impacts over their life cycle. Professor McMichael is developing methodologies and design advisors for process engineering, such as size reduction and materials separation for products such as automobiles, computers, consumer durables, and electronics.

Another current area of interest involves the management of residue from automobile shredders. An increasing weight fraction of the shredded hulk of a modern automobile is deemed a hazardous or special waste. Techno-economic investigation of alternative processes address finding value in recovered materials, reducing the cost of disposal, and mitigating the environmental impact of residuals.

Henry PiehlerPiehler's materials research included sheet metal formability, and triaxial consolidation of powder compacts and composite materials, which facilitates consolidation and improve properties compared to those achieved by pure isostatic compaction. Other materials research focused on fabrication and performance of surgical materials and devices, using in vivo tests designed to link prior processing with in vivo performance. He developed nondestructive testing procedures to predict incipient failures, as well as risk-management and regulatory strategies designed to respond to these performance evaluations.

His policy research focused on the career paths of Japanese and American engineers, in order to understand how the generation and dissemination of technical information occurs in these two countries. Professor Piehler's research included physical and analytical modeling of deformation processing systems and performance evaluation of mechanically fabricated components and products in research areas like medical device risk management, engineering manpower utilization, plus productivity and innovation.

Professor Piehler was on several committees of the American Society for Testing and Materials (ASTM), including the Committee on Medical and Surgical Materials and Devices.

Lester LaveB.A. (Economics) 1960, Reed College
Ph.D. (Economics) 1963, Harvard University.

Carnegie Mellon, 1963 - 2011

Professor Lester Lave’s work was broad in its focus - he examined the risk analysis of management, including air pollution, carcinogenicity of chemicals, safety of dams, and highway safety; and product and process design for the environment, including life-cycle analysis. With his student Eugene Seskin he published seminal work on the impacts of air pollution on human health, establishing the link between fine particles and mortality and eventually led to particulate air quality standards and emission regulations that will continue to save lives far into the future. Lave was recognized for his air pollution and public health work with election to the Institute of Medicine of the National Academies in 1982.

With colleagues Granger Morgan, Alex Farrell, and Jay Apt, Lave founded Carnegie Mellon’s Electricity Industry Center in 2001, which today is the largest interdisciplinary group working on all aspects of the electric power industry. During the 1980s, he contributed his expertise in the areas of risk analysis arena, automobile safety, dam design, diabetic truck drivers, fuel additive risks, and global climate change were but a few of the topics addressed in research by Lester and his students.

With colleagues Hendrickson and McMichael, Lave founded the Green Design Institute at Carnegie Mellon in 1992. This interdisciplinary center provided new approaches to pollution prevention and waste minimization. With numerous students, the group developed an inputoutput approach to make environmental life cycle assessment both consistent and rapid. They also had their share of controversy, such as their study of lead emissions from the life-cycle of lead-acid battery powered vehicles, which appeared in The New York Times and eventually the journal Science, entitled ‘Environmental Implications of Electric Cars.’ This article disparaged the use of lead-acid batteries and production of primary and secondary lead due to what they said are harmful emissions.

Lave served on, and chaired, numerous study committees of the National Academies (NRC). More recently he chaired the Academy report "Real Prospects for Energy Efficiency in the United States" that demonstrated large opportunities for saving energy by improving buildings. At the time of his death he was chairing an Academy committee on whether and how to make motor fuels from biomass.

Lave was a dedicated educator. He supervised roughly 40 Ph.D. and post-doctoral students, many of whom have gone on to make important contributions of their own in environmental science and technology. Many of the MBA students he taught have played important roles in the greening of U.S. and international industry. CEOs of several of the nation’s best-managed companies are his former students.

Lester was prescient in picking important problems and applying rigorous analysis. He was also exemplary in ignoring disciplinary boundaries. As a result, his legacy in a variety of important topics is enormous.

Herb ToorB.S. (Chemical Engineering) 1948, Drexel Institute of Technology. 

M.S. (Chemical Engineering) 1950 and Ph.D. (Chemical Engineering) 1952, Northwestern University.

Carnegie Mellon, 1953 - 2011

Professor Toor's teaching and research have been primarily in mainstream chemical engineering. He was Head of the Chemical Engineering Department at Carnegie Mellon, and subsequently Dean of Carnegie Institute of Technology. During the early days of the environmental movement, Professor Toor, Bob Dunlap (later the first Head of EPP), Mike Massey (the first joint Ph.D. from EPP), and Dave Ragone ran a project course to examine air-borne emissions in Pittsburgh - the precursor of the EPP project course.

After he became Dean of CIT, Professor Toor asked Bob Dunlap to develop a program to bring policy issues into engineering education and research. Bob Dunlap decided that collaboration with social scientists was needed, and, jointly with Gordon Lewis of the School of Urban and Public Affairs, wrote a proposal to start a program which was funded by the Sloan Foundation and which eventually became EPP.

Professor Toor's research has included studies concerned with extracting oil from oil shale and removing SO2 from stack gases, as well as fundamental studies in heat and mass transfer. He chaired the Committee on Evaluation of Sulfur Oxides Control Technology of the National Academy of Sciences.

Professor Toor is a member of the National Academy of Engineering, American Chemical Society, and American Institute of Chemical Engineers (AIChE), and a Fellow of the AIChE and the American Association for the Advancement of Science.
