Biographies

Ray Jayawardhana

Ray Jayawardhana is a renowned astrophysicist whose research explores the origin and evolution of planetary systems as well as the formation of stars and brown dwarfs. His group uses the largest telescopes on the ground and in space to do remote sensing of exoplanets, with a view to investigating prospects for life in the universe. He is a science team member for the James Webb Space Telescope's Near-Infrared Imager and Slitless Spectrograph (NIRISS) instrument, and his group has led Gemini Observatory large programs on high-resolution spectroscopy of exoplanet atmospheres. A prolific researcher, he has co-authored more than 180 scientific papers.

Jayawardhana is also an award-winning author of popular science books and a children's book, and more than 120 of his articles have appeared in The Wall Street Journal, The New York Times, The Economist, and other prominent outlets. He has received numerous accolades, including the Guggenheim Fellowship, Radcliffe Fellowship, and Carl Sagan Medal. Asteroid 4668 Rayjay is named after him. An avid traveler, he has visited more than 60 countries, all seven continents, and the Arctic.

Prior to joining Caltech, Jayawardhana served as provost of Johns Hopkins University and professor of physics and astronomy. As provost, he advanced the university's research, education, and outreach missions, overseeing its 10 schools and numerous interdisciplinary programs and support functions. Previously, Jayawardhana served as the Harold Tanner Dean of the College of Arts and Sciences and the Hans A. Bethe Professor at Cornell University.

Jacqueline K. Barton

Jacqueline K. Barton is the John G. Kirkwood and Arthur A. Noyes Professor of Chemistry, Emerita, at Caltech. Barton was awarded an A.B. at Barnard College in 1974 and a PhD in Inorganic Chemistry at Columbia University in 1978. After a postdoctoral fellowship at Bell Laboratories and Yale University, she became an assistant professor at Hunter College, City University of New York. Soon after, she returned to Columbia University, becoming a professor of chemistry in 1986. In 1989, she joined the faculty at Caltech, and from 2009–2019, she served as chair of the Division of Chemistry and Chemical Engineering.

Barton has pioneered the application of transition metal complexes to probe recognition and reactions of DNA. She has carried out studies to elucidate electron transfer chemistry through the DNA double helix, a basis for understanding long-range DNA-mediated signaling in DNA damage, repair, and replication.

Barton's awards include the American Chemical Society (ACS) Award in Pure Chemistry, a MacArthur Foundation Fellowship, and the Welch Award in Chemistry. She has been elected to the American Academy of Arts and Sciences, the National Academy of Sciences, the National Academy of Medicine, and the American Philosophical Society, where she currently serves as a vice president. Barton received the 2010 National Medal of Science, and the 2015 ACS Priestley Medal, the highest award of the ACS.

Peter B. Dervan

Peter Dervan is a Bren Professor, Emeritus, at Caltech. He obtained his PhD in 1972 at Yale University. After postdoctoral research at Stanford University, Dervan moved to Pasadena in 1973 as assistant professor at Caltech. Dervan was promoted to associate professor in 1979, professor in 1982, and Bren Professor in 1988. He served as chair of the Division of Chemistry and Chemical Engineering from 1994 to 1999.

Dervan received the 2006 National Medal of Science from President George W. Bush "for his fundamental research contributions at the interface of chemistry and biology and his influence in education and industrial innovation." Other awards include the American Chemical Society (ACS) Arthur C. Cope Award (1993), Willard Gibbs Medal (1993), Nichols Medal (1994), Kirkwood Medal (1998), ACS Alfred Bader Award (1999), Linus Pauling Medal (1999), Richard C. Tolman Medal (1999), Tetrahedron Prize (2000), Harvey Prize (Israel, 2002), ACS Breslow Award (2005), Wilbur Cross Medal (2005), and the ACS Priestley Medal (2022). He is a member of the National Academy of Sciences, the National Academy of Medicine, the American Academy of Arts and Sciences, the American Philosophical Society, the French Academy of Sciences, and the German National Academy of Sciences.

Dervan is a scientific co-founder of Gilead Sciences (1987). He served as a trustee of Yale University (2008–17). Dervan is considered an outstanding teacher with several teaching awards from the students at Caltech.

The Meaning of Academic Dress

The regalia of those in the academic procession have a specific symbolism that dates back to at least the 14th century. Academic institutions in the United States adopted a code of academic dress in 1895 that has been revised from time to time. The dress of institutions in other countries varies, and there is not a worldwide code, but the basic elements are present in all academic regalia.

The gown, of course, is the basic livery of the scholar, with its clear marks of rank and status—the pointed sleeves of the bachelor, the oblong sleeves of the master, the full sleeves and velvet trimmings of the doctor. Color is the very essence of the hood: color in the main body to identify the university; color perhaps in the binding to proclaim the subject of the degree—orange for engineering, gold for science, copper for economics, white for arts and letters, green for medicine, purple for law, scarlet for theology, and so on.

The Robert A. Millikan Hood

The passing of Robert A. Millikan's academic hood to the new president is a Caltech inaugural tradition. While he never accepted the title of president, Millikan was the administrative head of modern-day Caltech. In 1921, he left his professorship at the University of Chicago to become director of Caltech's new Norman Bridge Laboratory of Physics. Together with George Ellery Hale and Arthur Amos Noyes, he formed the executive council that molded the Institute into a preeminent research university, serving as chairman of the council from 1921 until 1945.


Gaudeamus Igitur

The song "Gaudeamus Igitur" has become an academic standard, sung around the world at graduations and other university ceremonies. Some verses of this anthem go back to 13th-century France, where they appear in a Latin hymn on the transitory nature of life. By the middle of the 18th century, students at German universities had combined the original medieval verses with new ones—including the now famous opening verse that begins Gaudeamus igitur, juvenes dum sumus ("Let us rejoice, therefore, while we are young")—to create a song that celebrated youth and the student life, in all of its highbrow (and lower-brow) aspects. In the mid-19th century, the song crossed the Atlantic to Yale, where still more verses were added for use at academic ceremonies.

Since then, verses have been added or subtracted for different occasions. The song also has been translated into many different languages, sometimes faithfully, sometimes quite imaginatively.

The verses below (which have been translated as closely as possible from Latin into English) combine the youthful energy and irreverent attitude toward authority that characterize Caltech students with a ringing endorsement of the academic enterprise to which they are devoted. The verses celebrate the Institute and its community of scholars—past, present, and future—who have done and will continue to do its work.

Gaudeamus igitur
Iuvenes dum sumus.
Post iucundam iuventutem
Post molestam senectutem
Nos habebit humus.

Ubi sunt qui ante nos
In mundo fuere?
Vadite ad superos
Transite in inferos
Hos si vis videre.

Vivat academia!
Vivant professores!
Vivat membrum quodlibet;
Vivant membra quaelibet;
Semper sint in flore.

Alma Mater floreat,
Quae nos educavit;
Caros et commilitones,
Dissitas in regiones
Sparsos, congregavit.

Let us rejoice, therefore,
While we are young.
After a pleasant youth
After a troubling old age
The earth will have us.

Where are they who, before us,
Were in the world?
Go to the heavens
Cross over into the infernal regions
If you wish to see them.

Long live the academy!
Long live the professors!
Long live each student;
Long live the whole community;
For ever may they flourish!

May our Alma Mater flourish,
Who taught us;
Who gathered together
Dear ones and comrades,
Scattered in remote places.

English Translation by Warren C. Brown, Professor of History, Caltech


Hail CIT

Caltech alma mater

Composed by Manton Barnes (BS '21)
Arranged by Raymond Burkhart

In Southern California with grace and splendor bound,
Where the lofty mountain peaks look out to lands beyond,
Proudly stands our Alma Mater, glorious to see;
We raise our voices proudly, hailing, hailing thee.
Echoes ringing while we're singing over land and sea,
The halls of fame resound thy name, noble CIT.
