Living—and Giving—the Caltech Dream

Growing up in Tehran, Iran, Mory Gharib (PhD '83) attended large, crowded schools. He was the kid who always raised his hand in class and asked tough questions. He craved one-on-one time with his teachers, which seldom came to pass.

So when the young Gharib read a newspaper article about a school in California with a three-to-one student-faculty ratio, it seemed almost unimaginable. Over the years, though, that school—Caltech—remained in his thoughts.

Years later, Gharib finally made it to Caltech as a graduate student. Since that time, he has built a distinguished career as a  researcher, mentor, inventor, entrepreneur, leader, and benefactor. And he has continued to search for the answers to tough questions.

"I couldn't have done this anywhere else," he says, referring to his career. "Caltech took care of me, and I have to take care of it."

In appreciation for the opportunities Caltech afforded him, Gharib—who currently serves as the Hans W. Liepmann Professor of Aeronautics and Bioinspired Engineering, director of Caltech's Graduate Aerospace Laboratories, and vice provost—has created an endowed fellowship fund to support new generations of Caltech graduate students.

Professor Rosakis Receives the Von Kármán Medal

Ares Rosakis, the Theodore von Kármán Professor of Aeronautics and Mechanical Engineering in the Division of Engineering and Applied Science, will receive the Theodore von Kármán Medal from the American Society of Civil Engineers. The medal was established and endowed in 1960 by the Engineering Mechanics Division of the society—now the Engineering Mechanics Institute (EMI)—in order to recognize distinguished achievement in engineering mechanics. The Von Kármán medal is the flagship medal of the EMI.

Rosakis is being honored for "discovering several fundamental physical phenomena in dynamic fracture of heterogeneous materials and interfaces at various length and time scales," according to the award citation. Particularly noted was his proposal of the concept of "laboratory earthquakes" and the associated unique experimental facility, which was established at the Graduate Aerospace Laboratories of the California Institute of Technology (GALCIT) more than a decade ago. Through experiments that reproduce the basic physics of earthquake rupture, he and his collaborators, including Caltech seismologist Hiroo Kanamori, were able to experimentally show that earthquake ruptures may propagate with "super-shear speeds"—speeds in excess of the bulk shear wave speeds of the surrounding material. They also conclusively proved that certain historic, large earthquakes did transition to super-shear and explained the unusual ground-shaking signatures that are characteristic of such catastrophic events.

"I feel extremely honored and humbled to receive the Theodore von Kármán Medal from the American Society of Civil Engineers," says Rosakis. "I am especially thrilled to receive an award bearing the name of von Kármán, whose remarkable achievements epitomize Caltech's natural interdisciplinary approach to science and engineering."

Rosakis has also served as the fifth director of GALCIT, which was established and directed by Theodore von Kármán in the early 1920s.

Quintessentially Caltech

How best to recognize Caltech's own Ahmed Zewail, the Linus Pauling Professor of Chemistry and professor of physics, and director of the Physical Biology Center for Ultrafast Science and Technology, who has served on Caltech's faculty for 40 years? President Thomas F. Rosenbaum had the answer: what he would later call a "quintessentially Caltech conference."

And so, on Friday, February 26, more than 1,000 people gathered to hear exceptional researchers, including 5 Nobel Laureates, from across disciplines consider our future as part of the full-day "Science and Society" conference that honored the career of Zewail, whom Rosenbaum called "a wizard of scientific innovation."

Slideshow: 

Caltech: A Personal Perspective

Ahmed Zewail, Nobel Laureate
Linus Pauling Professor of Chemistry and Professor of Physics, Caltech

Zewail provided an overview of his journey from a young child in Egypt to Caltech Nobel laureate. On the day he won the 1999 Nobel Prize in Physics, he recalled, Caltech president David Baltimore came to Zewail's house, but he refused to open the door. "We thought he was paparazzi," Zewail admitted.

The End of Disease?

Roger Kornberg, Nobel Laureate
Mrs. George A. Winzer Professor in Medicine, Stanford, School of Medicine

As advanced as we think we are, Kornberg said, scientists today understand less than 1 percent of human biology. Attracting more young people to the field of medical research is therefore critical. "Young scientists are the most likely to discover something," he said. "And numbers matter."

The Future of Medicine

David Baltimore, Nobel Laureate
Caltech President Emeritus
Robert Andrews Millikan Professor of Biology, Caltech

The human body can survive a maximum of roughly 120 years, according to Baltimore. He predicted a future in which scientists work to push that envelope, using gene editing "to liberate us from the process of aging" and "to perfect the human body, whatever that means."

The Future of Quantum Physics

H. Jeff Kimble, Member, National Academy of Sciences
William L. Valentine Professor and Professor of Physics, Caltech

Kimble's lecture about the future of quantum physics included predictions about quantum computing, quantum simulation, and quantum metrology. "Science helps hold us together and appreciate our sameness rather than our differences," he said.

Time, Einstein, and the Coolest Stuff in the Universe

William Phillips, Nobel Laureate
Physicist, National Institute of Standards and Technology
Distinguished University Professor, University of Maryland

In a hands-on demonstration, Phillips put on a pair of lab goggles and dunked a variety of items—a rose, a racquetball, several inflated balloons—into a vat of liquid nitrogen to help demonstrate his overall point: that we can create super-accurate atomic clocks by cooling down atoms to astoundingly low temperatures.

Inequality and World Economics

A. Michael Spence, Nobel Laureate
Philip H. Knight Professor and Dean, Emeritus
Stanford University Graduate School of Business

Spence discussed a number of global economic trends—including the decline in middle-class jobs and the rise of job-eliminating technologies—in a lecture that considered the disparities between rich and poor. "I'm a little worried about what's going on in the global economy right now and I tend to be an optimist," he said.

The Future of Space Exploration

Charles Elachi, NASA Outstanding Leadership Medal Recipient
Caltech Vice President
Director, Jet Propulsion Laboratory

Elachi said he believes we will establish a space station on Mars and that humans will begin visiting the planet by 2030. But, he noted, "It's important that we take care of our own planet. It's the only thing we have, at least for now."

How best to recognize Caltech's own Ahmed Zewail, the Linus Pauling Professor of Chemistry and professor of physics, and director of the Physical Biology Center for Ultrafast Science and Technology, who has served on Caltech's faculty for 40 years? President Thomas F. Rosenbaum had the answer: what he would later call a "quintessentially Caltech conference."

And so, on Friday, February 26, more than 1,000 people gathered to hear exceptional researchers, including 5 Nobel Laureates, from across disciplines consider our future as part of the full-day "Science and Society" conference that honored the career of Zewail, whom Rosenbaum called "a wizard of scientific innovation."

The speakers lectured on a broad spectrum of topics, ranging from space travel to global economic inequality to what happens when five inflated balloons are stuffed into a vat of liquid nitrogen. Their talks were moderated by Nathan Gardels, editor in chief of The WorldPost, and Peter Dervan, the Bren Professor of Chemistry, who noted while introducing Zewail that they have been close friends ever since their early days starting as assistant professors together at Caltech.

"What an extraordinary day," Rosenbaum said at the conclusion of the event, held in Beckman Auditorium. "It's unusual to find a series of talks at this incredibly high level of excellence—intellectually deep and pedagogically engaging."

As many of the speakers pointed out, Zewail's list of accomplishments is staggering. He has authored some 600 articles and 16 books and was sole recipient of the 1999 Nobel Prize for his pioneering work in femtochemistry. In the post-Nobel era, he developed a new field dubbed four-dimensional electron microscopy. He has been active in global affairs, serving as the first U.S. Science Envoy to the Middle East and helping establish the Zewail City of Science and Technology in Cairo, which he hopes to turn into "the Caltech of Egypt."

"Ahmed is a very special kind of scientist," said Fiona Harrison, chair of Caltech's Division of Physics, Mathematics and Astronomy, during the conference's introductory remarks. She noted the "incredible breadth of his research" and cited a colleague's observation that "Ahmed is someone who never has average goals."

Jackie Barton, chair of Caltech's Division of Chemistry and Chemical Engineering, praised Caltech for taking a chance on Zewail four decades ago, when he was a young scientist. "He had this vision," she said. "The vision was to watch the dynamics of chemical reactions, to watch reactions happening on a faster and faster time scale, indeed to watch the making and breaking of chemical bonds."

She added: "He has this intuitive sense of the dynamical motions of atoms and molecules, their coherence, or lack thereof, as the case may be. And then he has this extraordinary attention to every detail, so that he's able to meld together theory and experiment and understand that dance, that choreography of atoms and molecules as they carry out a reaction."

To further honor Zewail, Caltech presented him with a rare book of Benjamin Franklin's speeches and scientific research—on lightning rods and the aurora borealis, among other phenomena—that is signed by Rosenbaum and all of Caltech's former presidents. Caltech Provost Ed Stolper noted that it is the only book authored by Franklin that was published during his lifetime.

As Stolper noted in his introductory remarks, the gift is a fitting one for Zewail, who has come to embody the ideal of Caltech, a place "where scientists and engineers are limited only by their imagination." He added Ahmed is one of the few scientists that, like Benjamin Franklin and Linus Pauling, not only excelled in science but has made a broader impact on society through his writings and actions.

Two Named Air Force Young Investigators

Venkat Chandrasekaran and Thomas Vidick have received grants from the Air Force Office of Scientific Research through its Young Investigator Research Program (YIP). The award, given to scientists and engineers who have received their PhD in the last five years, is intended to foster creative research in science and engineering areas of interest to the Air Force.

Chandrasekaran is an assistant professor of computing and mathematical sciences and electrical engineering in the Division of Engineering and Applied Science. His grant will be used for a YIP project titled "Latent Variable Graphical Modeling for High-Dimensional Data Analysis."

"The analysis of massive datasets arises in a range of contemporary problem domains throughout science and technology," Chandrasekaran says. "A central objective in data analysis is to learn simple or 'concise' models that characterize the statistical correlations among large collections of variables. Concisely specified models provide useful interpretations of the relationships underlying a set of variables. However, unobserved phenomena complicate this task significantly because these extraneous variables induce relationships among the observed variables that are complex to describe. The objective of this research project supported by the Air Force is to develop principled and computationally tractable methods for statistical modeling that account for the effects of unobserved phenomena."

Vidick is an assistant professor of computing and mathematical sciences in the Division of Engineering and Applied Science. His YIP project is titled "Towards a secure quantum network."

"Developing computing devices based on the laws of quantum mechanics will dramatically upend existing communication networks in two major ways," Vidick says. "First, by providing new classes of attacks on existing cryptosystems. Second, by turning formerly impossible cryptographic tasks into game-changing possibilities. My research aims to address the following challenge: What are the protocols and notions of security that will allow efficient and secure interactions in the emerging network of classical and quantum devices?"

"I think it's fantastic that the Air Force Office of Scientific Research is recognizing the urgency of theoretical research in quantum communications and cryptography," he says. "I am honored my research has been selected for the award."

Ten Years of DNA Origami

On March 16, 2006, Research Professor of Bioengineering, Computing and Mathematical Sciences, and Computation and Neural Systems Paul Rothemund (BS '94) published a paper in Nature detailing his new method for folding DNA into shapes and patterns on the scale of a few nanometers. This marked a turning point in DNA nanotechnology, enabling precise control over designed molecular structures. Ten years later, the field has grown considerably. On March 14–16, 2016, the Division of Engineering and Applied Science will hold a symposium titled "Ten Years of DNA Origami" to honor Rothemund's contribution to the field, to survey the spectrum of research it has inspired, and to take a look at what is to come.

"Think about DNA origami as a general-purpose pegboard for organizing nanometer-sized things," Rothemund says. "Each DNA origami has 200 different attachment points, to which one can attach proteins, or tiny gold balls, or fluorescent molecules, or electrically conductive carbon nanotubes. There is no other way to juxtapose combinations of these elements into complex arrangements, and this is what researchers around the world, from biologists to physicists, are using DNA origami for. Biologists use DNA origami to position different protein enzymes next to each other, so that one enzyme can hand off its products to the next enzyme in a sort of nanoscale assembly line. Others are organizing electronic components in an attempt to make nanocircuits."

The symposium was organized by Erik Winfree, professor of computer science, computation and neural systems, and bioengineering. "This amazing Caltech invention has had a remarkable impact in molecular nanotechnology research," he says.

Talks will cover DNA nanotechnology, self-assembly and pattern formation, computational algorithms and software for origami design and analysis, applications in biology and biomedicine, applications in quantum physics, molecular motors and mechanical devices, biophysics and thermodynamics and kinetics, and more. The talks are open to the public, but attendees must first register online.

Caltech Bioethics Forum: HeLa Cells in the Lab

Henrietta Lacks died of cervical cancer in 1951 and, ever since, samples of her uniquely immortal cancerous cells have been used in scientific research, sparking great leaps in medical knowledge.

But the cells—taken without her knowledge or consent—have also fueled controversy and called into question the ethical underpinnings of the research they made possible. Her story, made famous in the book, The Immortal Life of Henrietta Lacks, by science writer Rebecca Skloot, underscores the continuing need—65 years after her death—for society to find a way to balance the advancement of medical knowledge with the protection of individual rights.

At a February 22 bioethics forum at Baxter Lecture Hall, Caltech president Thomas F. Rosenbaum introduced a panel of Caltech faculty that examined the ethics of using Lacks's cells—known as HeLa cells—along with issues of privacy, informed consent, and who profits from the technologies her cells engendered. Caltech trustee Ronald L. Olson moderated the panel of Caltech faculty, which featured David Baltimore, President Emeritus and the Robert Andrews Millikan Professor of Biology; Ellen Rothenberg, the Albert Billings Ruddock Professor of Biology; Barbara J. Wold, the Bren Professor of Molecular Biology; and Changhuei Yang, professor of electrical engineering, bioengineering, and medical engineering.

The evening event revisited a topic that incoming freshmen had tackled earlier in the academic year in roundtable discussions of the book, which the students had been asked to read prior to their arrival at Caltech.

"HeLa cells were a miracle," said Baltimore, who has used them in his research since 1962. After noting their incalculable value—and how rare it was to have found cells that underwent the specific mutations that conferred their ability to divide indefinitely in culture—he brought the discussion back to the question of who owns the cells.

"So it seems to me the question is, what rights does she have as a consequence of this rare, basically random event, that made her cells different than anybody else's cells? . . . We are the product of a genetic lottery. What rights do we get as a consequence of our particular genes? Everyone else around us has a representation of those same genes, but not identical. What is ownership in this case?"

Rothenberg discussed how the cells have enabled key advances in molecular biology, stem cell research, and immunology—advances that would have been considered "complete science fiction fantasy" when Lacks was alive. Because the innovations her cells made possible would have been impossible to foresee, questions naturally arise as to whether Lacks could have understood the ramifications of her consent, had it been sought.

The structure of DNA was only discovered two years after Lacks' death, and the revolution in molecular biology that followed completely transformed the possibilities for use of any human cells that were able to grow in culture. "How could she possibly have given informed consent? In the case of a rapidly advancing field like molecular biology, there's no way she could have been asked at that time what she was really consenting to," Rothenberg said.

When the conversation returned to ownership of a patient's cells, and who should profit from their use, Rothenberg pointed out that simply saying the patient owns them, period, could generate a raft of unintended consequences. For example, medical institutions might, for legal liability reasons, refuse to accept certain tissue samples, hampering the delivery of personalized medicine to patients. Equally disturbing, she says, would be the possibility that the commercially valuable products of cells might incentivize individuals to view a cancer-patient relative "as a possible cash cow, and sell their tissues in the hopes of winning the lottery. . . . You definitely don't want people to be in a position where they or their family members want to sell parts of their body because they're starving."

Wold said her research seldom involves HeLa cells but, she added, "that doesn't mean I'm not an avid consumer of what's been learned over 60 years of studying them." She hailed the "beautiful science" the cells have engendered, but lamented the scientific community's repeated failings in communicating with and involving the Lacks family over the years as to how the cells were being used and what was being learned from them. For example, she said, teams of researchers in Germany and at the University of Washington sequenced and published the HeLa genome in 2013 and made the information freely available worldwide. In doing so, however, they made portions of the family's genome public—without thinking to seek the family's approval or tell the family what was happening. The research community "quickly recognized this as a catastrophe," said Wold, prompting the creation of a board that includes Lacks family members and now regulates access to the data.

Such ethical considerations continued during the event's Q&A, which stirred discussion about such critical questions as how to address medical privacy when one family member's consent might make public another family member's information, and whether proposed consent rules might jeopardize access to older cell lines that were obtained prior to a stricter consent regime.

Yang, whose lab has used HeLa cells since 2008, said he only recently learned about the ethical concerns around their provenance, adding, "Honestly I was quite surprised to find there were all these [controversies]. . . . As an outsider to American culture—I actually grew up in Singapore—my instinct would be that the DNA is a common good, not personal property. If my cells would be useful for research, I would gladly give them up without any expectations."
