At the UCLA Henry Samueli School o Engineering and

Applied Science, we are committed to interdisciplinaryscholarly work in emerging areas. And throughout the

school, more and more o this work is happening outside

o traditional engineering disciplines.

This commitment is highlighted by two eature stories

in this issue. The cover eature on Demetri Terzopoulos

introduces his many years o progress in human simulation and computer

modeling — work that was rst popularized as special eects in

Hollywood lms earning Terzopoulos an Oscar, but now has applications

in medicine, security and other elds. A second eature on Ioanna Kakoulli

details her research and analysis o ancient art and artiacts using

advanced engineering techniques.

One o my priorities as dean has also been to increase diversity in both

the student population and among aculty at UCLA Engineering. In the

past ew years, we have recruited some exceptional women to the aculty

and some o their work has been included in this issue. Terri Hogue is

leading an outreach program that helps to get young students excited about

science; Yu Huang received a 2009 PECASE Award, the nation’s highest

honor or young researchers, or her work in renewable clean energy;

Diana Huaker has created a leadership program in clean technology;

and I have already mentioned the eature on Ioanna. Also, o our six new

aculty hires or 2009, three are women.

Engineering has historically been a male-dominated eld. But this is

changing. And we are proud to be playing a signicant role in this move-

ment, with women who set the highest standards or excellence in the

classroom, in innovative research, and in serving the community.

These labels are oten only or convenience. UCLA is

home to innovators who cross disciplines, combining

advanced technology with classical scholarship to create

new knowledge.

One great example o this type o scholar is Ioanna

Kakoulli, who works in the emerging eld o archeometry,

an integration o science and archeology.

Kakoulli is an associate proessor o materials science

and engineering, with a joint appointment at the UCLA/ 

Getty Archaeological and Ethnographic Conservation

Program and the Cotsen Institute o Archeology.

Kakoulli’s research includes the continuing study o an-

cient Greek painting and color technology, using advanced

analytical techniques and synchrotron light source to

decipher the materials ancient artists used.

At the height o the Late Classical to Hellenistic Period

(~400 to 100 BC), painting was particularly signicant,

since it was not conned to a specic area, nor to a specic

ethnic group. Art became the lingua ranca among dier-

ent groups o people, rom the Balkans to the Levant, and

as ar as India, throughout which ideas and goods fowedreely. Greek painters had perected techniques and manu-

acturing o materials that resulted in lasting, beautiul art.

Painting during this period went beyond the alluring

composition o beautiul colors. Pliny the Elder (1st Cen-

tury AD) provides the most signicant insight in ancient

Greek art, mentioning Agatharchos rom Athens (5th

Century BC) as the rst artist to introduce perspective in

painting, and Apollodoros, a vase painter, as the one who

expressed realism and introduced shading that was

extensively used by acclaimed Greek painters, Zeuxis

and Apelles.

“Pliny urther reers to Polygnotus rom Thasos ‘...wh

rst depicted women with see-through clothing...’ Scien

tic studies o surviving examples rom this period have

shown how pictorial representations — something like

what we understand o paintings today — was born in t

period,” said Kakoulli.

“Using modern technology, we are unmasking the

secrets o ancient Greek painters and explaining, both in

historical and technical terms, the development o pictorial

means, such as, the use o shading, three-dimensionality,

spatial perspective, transparency, and gilding - innovations

that characterize the Hellenistic period.”

Creating these works required more than just a keen eye

and skilled hand. Scientic techniques have revealed these

ancient artists used local and imported natural minerals,

dyes and plant gums, because o their luster and material

characteristics. They also used articial composites such as

high red ceramics glass rits and organo-metallic complexes

with the desired properties.

One o the works Kakoulli has analyzed extensively is the

marble throne that decorates the tomb o Eurydice Sirra,

Queen o Macedonia in the 4th Century BC, and better

known as the grandmother o Alexander the Great.

The ree-standing throne is the most outstanding eature

o the tomb. The legs and armrests are decorated with emale

gures, lions and deer, and mythological creatures like gri-

ns. The most impressive part o the throne is the painted

‘picture panel’ representing a painting o Pluto and Perse-

phone on a our-horse chariot.

“For the study o this unique and archaeologically signicant

artiact, a variety o techniques were used. These included,

broadband imaging rom the ultraviolet to near inrared; opti-

cal and electron microscopy; inrared and x-ray spectroscopy,

as well as chromatographic techniques,” said Kakoulli.

According to Kakoulli, the analysis has shed new light

on the technology o ancient painted monuments, including

highly sophisticated techniques using a variety o natural

(local and imported) and synthetic materials.

Though the technology o the ancient Greeks remains Ka

oulli’s primary research interest, she also collaborates with

other UCLA researchers.

She is the co-director o a project that examines Pre-

Columbian mummied human remains in Northern Chile’s

Tarapaca Valley. This project incorporates modern medicin

as well as natural and orensic science to examine organic

materials — to the molecular level — that can deduce the

types o diseases they may have had, and the types o drugs

they may have used.

More recently, she is leading a research project on unique

12th Century Byzantine murals at the monastery o St. Neo

phytos in Paphos, Cyprus.

Kakoulli teaches students in the UCLA/Getty conservatio

program and in the materials science department through

hands-on research projects.

“Our students are really very ortunate to have access to

state-o-the-art acilities with advanced instrumentation at

UCLA and the Getty Villa. Undoubtedly, UCLA and the

Getty oer a unique educational and research platorms tha

enable and enhance learning and discovery. Our approach

exposes students to critical and creative thinking that helps

prepare them or successul careers,” said Kakoulli.
