Chancellor Chang-Lin Tien on his 60th birthday

It is a pleasure tamhonor the achievementsof Chancellor Chang-Lin ‘Hen as he celebrates his 60th birthday. On this occasion, it is fitting for his colleagues toapplaud his sign&ant
contributionsin the field ofheat transfer.
Chancellor Tien was born in Wuhan, China, on 24
July 1935. Before and after World War II his family
fled twice to Shanghai and Taiwan, where he completed his undergraduate
education at the National
Taiwan University. He came to the U.S. in 1956 as ateaching fellow at the University of Louisville. Afterearning his master’s degree in 1957, he moved to Princeton University where he was a Howard Crathorne
Phillips Fellow and earned a second master’s and aPh.D. degree in 1959. Chancellor Tien then joined thefaculty at University of California-Berkeleyin 1959
as an Acting Assistant Professor of Mechanical Engineering, where he initiated his research program which
was to become distinguishedby its breadth, originality, comprehensivenessand impact.
Chancellor Tien has published his research resultsin more than 280 journal articles and more than 30books, monographs
and invited articles. His immense
contribution
to the basic knowledge of thermal sciences over the past 30 years are characterized
by itsfundamental
quantificationof phenomenathat aresignificant
to complex
engineering
applications.
Throughout his career, he has pioneered new researchareasby questioning
establishedassumptions,uncovering dominant processes, mapping domains ofapplicability,and formulating
methods to quantify
phenomena outside established limits.
His keen insight is demonstrated
through his scholarship on thermal radiation.
Among the first heattransfer investigators to focus on thermal radiation ingases, he provided a basis for quantifying
gaseousradiation
propertiesand developed
computational
methods to quantify transport in such systems. This
work provided a foundation
for current engineering
approaches. Continually seeking to discover the next
frontier, his early work on thermal radiation transport
in small domains is now the basis for the field. Professor Tien also contributed to the properties of solids
in the form of particulates and surfaces. The first toprovide a sound theoretical footing for the characterization of dependent scattering, he provided experimental findings to delineate the regions of applicability. His pioneering research still continues in thearea of thin film structures.
The exceptional contributionsof Chancellor Tien’s
research in the area of thermal radiation are matchedby his work on thermal insulations. As in most of his
research endeavors, he initiated this field with basic
formulation and analyses. He addressed all transportmodes for multilayer, cryogenic and microsphere insulations. The work on porous insulation led to general
analyses and experiments involving thermal transportin porous media. Clarity in thought, innovation

approach, and an intimate connection with application are overriding characteristics of this research.
Most recently Chancellor Tien has focused on microscale thermal phenomena, providing yet anothercornerstone to the field of heat transfer. His original
efforts in thermal stability have now been utilized in
the area of high temperature superconductor films.
He initiated and developed the fundamental work inthermal transport in micro-length and femto-timescales. These efforts are of paramount importance incharacterizing the thermal behavior of sensors, laser
sources, superconductors and quantum well structures, to name a few. Always seeking the most significant finding in his research, Chancellor Tien combines technical insight, theoretical analysis andfocusing experiments to discover the dominating processes, provide basic properties and validate models.
The breadth of Professor Tien’s contributions isexhibited by this incomplete listing of additional areasof research: boundary layer flows, turbulent transport,forced convection, gas-solid flows, pool boiling,
hypersonic flows, rotating flows, cell transport, heatpipes, fire phenomena, solar energy, reactor safety,
condensation, cryogenics, interfacial transport andthermosiphons. His efforts in these areas include
experimental,analytical and numerical methodologies. In each area that he has undertaken, he has
expanded and enhanced the basic understanding of
the fundamental phenomena, which has had an
impact on researchers worldwide.
Professor Tien’s inquisitive approach and tirelessenergy inspired and guided more than 60 students intheir doctoral studies. He continually implored hisstudents to ‘think deep,’ to explore ‘new ideas’ and toinvestigate ‘the limits.’ He is a true mentor and scholar, and imparted to his students in universities, laboratories, and industry around the world the needfor excellence, quality and high standards in allendeavors.
Chancellor Tien is a national and international
champion of his discipline. He has served or is serving
in an editorial capacity to 14 thermal-oriented publications, including being a current editor of theInternational Journal of Heat and Mass Transfer,
Experimental
Heat Transfer, and International
Communications in Heat and Mass Transfer. His ser-vice is continually sought on advisory bodies, withparticipation
at NBS (now NIST), NSF, ASEE
National Advisory Council, and the CRC Press. He
has chaired numerous professional society activities
including the International Center for Heat and MassTransfer, the AIAA Thermophysics Committee, theASME Heat Transfer Division Executive Committee,
past ASME National Heat Transfer Conferences andAIAA Thermophysics Conferences, and the U.S.
Scientific Committee for the 8th International HeatTransfer Conference. His technical advice is sought

and valued throughout the international
researchcommunity.
In concert with his stature as a researcher, Chancellor Tien is an acknowledged leader with global
influence in higher education. Rising through the academic ranks, he became a full professor in 1968, served
as Chair of the Department of Mechanical Engineering from 1974 to 1981, and was Berkeley’s Vice
Chancellor-Researchfrom 1983 to 1985. In 1987, hewas appointed the A. Martin Berlin Chair Professorof Mechanical Engineering, a title he still holds today.
He left Berkeley in 1988 and served for 2 years as
Executive Vice Chancellor and UC1 Distinguished
Professor at University of California-Irvine.
ChangLin Tien took the position of Chancellor of the University of California-Berkeley in July 1990, as the first
Asian-American to head a major research university
in the United States. Chancellor Tien is noted for hisenergetic approach and has earned wide praise for his
openness, sensitivity and accessibility.
Chancellor Tien’s distinguished record as a scientist
and educator has been widely acknowledged. He hasreceived many honors, including a Guggenheim Fellowship, the Max Jakob Memorial Award, andHonorary Member of ASME-ASME’s
most distinguished honor. Among several teaching awards,Chancellor Tien in 1962 became the youngest professor at age 26 ever to win University of CaliforniaBerkeley’s prestigious Distinguished Teaching Award.
A recipient of honorary doctoral degrees from several
universities, he currently serves on the Board of Trustees at Princeton University and the Asia Foundation. He has been a member of the National Academy of Engineering since 1976 and was elected in 199 1
as a Fellow of the American Academy of Arts andSciences. These honors are richly deserved. Chancellor
Tien’s contributions to the heat transfer discipline, tothe engineering profession, and to higher education
exhibit his deep and vigorous commitment to developing and maintaining excellence, and to preserving andenhancing diversity at all levels.
On the occasion of his 60th birthday, it is a great
pleasure and honor for his students, colleagues andfriends all around the world to recognize his distinguished and pioneering accomplishments. We wish
both Chang-Lin and his wife Di-Hwa good health andcontinued professional success in the many years tocome.
