Ralph Adolphs: The Social Brain and Autism


Ralph Adolphs (PhD ’93)

Bren Professor of Psychology and Neuroscience and Professor of Biology; Director of the Caltech Brain Imaging Center

My laboratory uses cognitive neuroscience approaches to understand human social behavior.  This includes techniques such as brain imaging, eyetracking, and electrophysiology, and makes comparisons between several different patient populations.  One focus has been to compare high-functioning people with autism to neurological patients who have focal lesions or disconnections of brain structures.  Another focus has been, in collaboration with local neurosurgeons, to record activity from single cells in the brains of patients who have implanted depth electrodes.  Together, these varied approaches are revealing to us how the brain processes information from faces, how we use such information to understand other people, and how this process can dysfunction in autism.

Recovery of the Function in Major Spinal Cord Injury Using Epidural Stimulation


Joel Burdick

Richard L. and Dorothy M. Hayman Professor of Mechanical Engineering and Bioengineering


Spinal Cord Injury (SCI) affects nearly 1,250,000 people in the U.S. This talk focuses on a recent collaboration between Caltech, UCLA, and Univ. of Louisville aimed at developing new therapies for motor complete SCI based on multi-electrode arrays implanted over the lumbosacral spinal cord. SCI patients receiving this therapy have been able to stand independently and make some voluntary movements.  They have made surprising gains in cardiovascular health as well as improved autonomic function such as bladder, bowel, and blood pressure regulation.

Bob's "Big Boy" Finds Some New Friends

Screen Shot 2013-07-10 at 9.06.19 AM.png

From Legends of Caltech, Vol. 1

If you've ever looked around southern California for a place to eat, you've seen him. You can't possibly have missed him. An obese little kid with red-checked suspender pants that are too long. Wears his hair like Ronald Reagan (both tend to use too much grease). And, Statue-of-Liberty-style, he holds aloft the reason for his oblate physique: a lone Bob's hamburger (with cheese, no fries). Yes, we're talking about "Big Boy."

Over the years, countless Techers have journeyed to the residence of Big Boy known as "Far Bob's" (in east Pasadena on Colorado Boulevard). (By the way, nobody ever went to "Near Bob's"—on Colorado Boulevard near PCC—but there's also nobody who can tell you why.) But in the fall of 1958, a quartet from Fleming House realized that, for all their treks to Far Bob's, Big Boy had never once come to see them. So, to the Fleming House Quadruple Alliance (Bruce Allesina '59, Bob Pailthorp '59, Kirk Polson '59, and Gordon Hughes '59), the mission was clear: Kidnap Big Boy from Far Bob's.

A ransom note demanding 10,000 hamburgers for his safe return was left behind.

At first cut, it looked like a fairly straightforward operation. They took Nelson Byrnes' trailer over to the restaurant at 2:00 a.m. and waited in the parking lot. However, after several hours of waiting, they realized that the place never really closed. After the cleaning crew left, the delivery trucks started arriving. 

So, secure in their faith that you can get away with just about anything if you look official enough while you're doing it, our men unbolted the Big Boy statue anyway and drove off with him. A ransom note demanding 10,000 hamburgers for his safe return was left behind. 

The morning manager of Far Bob's was neither impressed nor snowed, and it took him only milliseconds to figure out where his little kid was. He was dutifully returned. Big Boy is shown in the photo standing in Fleming courtyard and saying goodbye to all of his new-found friends before returning to his usual place of employment. 

Alumni Career Spotlight


Dr. Heather Dean started out as an electrical engineering major at Caltech interested in neural networks. She was soon exploring the biological side of such networks and earned a master’s degree in Computation and Neural Systems along with her B.S. in Electrical Engineering. Her time at Caltech set her on the path of neuroscience research, and she went on to earn a PhD in Neurobiology at Duke University. After graduate school, she spent six years at New York University helping to found the lab of Dr. Bijan Pesaran. She is currently an AAAS Science and Technology Policy Fellow at the National Science Foundation where she works on issues related to cutting-edge interdisciplinary neuroscience, data sharing, science communication, and broadening participation. Heather is President of the Caltech Alumni Association.

What is the career path that led you to become an AAAS Fellow at the National Science Foundation?

I thought I would become an electrical engineer partly because my dad is an electrical engineer and my inspiration. He worked on neural networks, so when I came to Caltech, I asked about neural systems. Because of that, I began taking classes and doing research in Computation & Neural Systems, CNS, which led to a SURF with Dr. Gilles Laurent that I very much enjoyed. I spent an extra year at Caltech working on neuroscience research and taking CNS classes, and that turned into a master’s degree. It was really Dr. Laurent that encouraged me to apply to graduate school, and that’s how I became a neuroscientist. After six years of graduate school I was not yet thinking about my next steps, but at an event, I went to say congratulations to a Caltech alum that I understood had recently received a faculty position at NYU. I introduced myself as a Caltech alum, and we had at least seen each other years ago back at Caltech and at conferences. He offered me a postdoc, so it’s because of the Caltech network that I then did a postdoc at NYU.

I was interested in doing something broader than starting a lab of my own; I always enjoyed leadership positions when I was at Caltech. At Caltech I served as the president of the Caltech Y, and at Duke I served on several committees. It was a chance to do something greater than a single avenue of research. I always liked the idea of moving into something that had a broader impact. I applied for the AAAS Science and Technology Policy Fellowship, received it, and was placed at the NSF this year.

What does the work day of a Fellow at the National Science Foundation look like?

I’m in the Directorate for Social, Behavioral, and Economic Sciences, and I’m working on the big issues that are relevant to all of the programs in my directorate, such as improving the replicability of published findings in research and broadening participation. I’m especially interested in neuroscience, so one thing I’ve been working on is neuroscience policy, both at my job and also on the side through a group I call NeuroPolicy. I bring in speakers to talk about the intersection of neuroscience with policy, media, law, and ethics. NeuroPolicy has been a terrific experience that has allowed me to broaden my network in D.C.

How has the Caltech network helped you?

Being a Caltech alumna… it’s great! I can easily reach out to speakers for my policy group that are Caltech alumni. I got to know my husband because he’s a Caltech alum. He scanned my brain when I first arrived at NYU and when I mentioned I had done this before at Caltech, it started the conversation.  We were later married at Alumni House at Caltech. So the Caltech network has helped me personally and professionally.

What has been your biggest work achievement so far?

That’s difficult to say. In academia I’m proud that I’ve helped start two labs. I was one of the first grad students in my lab at Duke and the first postdoc at my lab at NYU. It was a lot of hard work, but I enjoyed it and am very proud of what we did there. I’m also proud of what is happening now in D.C. – putting together a network of people that are working in neuroscience policy. Two weeks ago I put together a symposium on neuroethics and invited people from throughout government – people who are working on neuroscience and new technologies.  The symposium was great and I’m very proud of that.

Can you think of a challenging interview question or situation and how you responded?

There was an interview question for my fellowship that I was almost asked, but I ended up answering in the previous question. An interviewer asked me why I had received both my bachelor’s and master’s degrees at the same time. I explained that when I was at Caltech, in my senior year I was taking 54 units, the maximum amount you could take without overloading, I was on the men’s varsity water polo team, I was the president of the Caltech Y, a waitress at the Athenaeum, I was TAing a grad-level CNS course, and I went to a conference in Washington, D.C. during midterms.  Needless to say, I did not do so well on midterms. I went to the Dean and told him that I didn’t know what to do, I had always been an A student, and I was overwhelmed. The Dean, Dr. Jean-Paul Revel, said “It’s okay.  You can drop this 12 unit EE class, and you’ll still have a full load. Take a couple of terms off, and come back to us in the fall.” Fortunately I had done the SURF project with Dr. Gilles Laurent the previous summer, and he said he would happily hire me while I was taking time off, so I did research for those nine months. Because of that, he wanted to make sure I had my master’s degree in CNS. After I answered that question, the interviewer told me, “I was going to ask you how you deal with a failure or setback, but now I know, you get a master’s degree.”  I think that very much helped me earn my fellowship.

What advice do you have for students or alumni who would like to do exactly what you’re doing?

I would say that there is often a push to concentrate simply on your academics whether you are a student or postdoc. My advice is to not be so narrow and make sure that you’re gaining many different skills. I very much appreciated receiving leadership training as a member of the ExComm of the Caltech Y and serving in various offices for the Graduate and Professional Student Council at Duke.  Because of that leadership involvement at Duke, I was asked to write a bi-weekly column for the Duke Chronicle. All of these experiences certainly helped me as I progressed to the next point in my professional life. Don’t box yourself in – make sure you’re getting a broad variety of experiences – get the writing experience, get the leadership experience, and build your network.

What is the best career advice you have received?

I had an advisor tell me that the job you’re most likely to get is the one for which you’re asked to apply. So build your network, make sure people are aware of what you’re doing, and when an opportunity comes up, whether or not you think it fits, make sure you at least explore it. It could become your dream job, or it could just become a good opportunity to practice applying and interviewing for a position. Regardless, it will help build your network.


Systems Medicine and Proactive P4 Medicine: Revolutionizing Health Care

Systems Medicine and Proactive P4 Medicine: Revolutionizing Health Care

Lee Hood (PhD ’68)

President, Institute for Systems Biology


We are at a tipping point in medicine, for the approaches of the old medicine are already beginning to be replaced by a medicine that is predictive, preventive, personalized, and participatory (P4). A major component of P4 medicine is the systems approach to disease, or systems medicine – employing global and comprehensive analyses of the disease process. Systems medicine is already creating powerful new genetic approaches to identifying disease genes; it is turning blood into a window for assessing health and disease in the individual; it is determining the genome sequences of tumors to identify targets for preexisting drugs; it is stratifying a disease into its different subtypes so that a proper impedance match against effective drugs can be achieved; it is beginning to develop entirely new, more rapid, and less expensive approaches to the creation of drugs; and it is beginning to assess wellness in individual patients.

I will discuss these revolutions in medicine with specific examples. I will also talk about some of the emerging technologies that are enabling P4 medicine – powerful sequencing machines for deciphering human genomes, a systems approach to blood diagnostics, new approaches to detecting proteins and the analyses of single cells. 

P4 medicine is the convergence of systems medicine, big data analytics, and patient-activated social networks. I will discuss these latter features and predict where each of the four Ps will be in 10 years. I will then discuss the impact that P4 medicine will have on society, along with our efforts to bring P4 medicine to patients.
