As Chair of the Division of Engineering and Applied Science (EAS), what gives me the most pride is the quality of our faculty and students and the standards that Caltech has always managed to keep in a world full of continuous compromises and scientific buzz words. We do not need large numbers of faculty and students to stand out among our peers, contribute, and make a great impact—we need only quality. In fact, our insistence on remaining small ensures that we continue to hire the best faculty and educate the most talented students.
One of our greatest accomplishments over the past year has been the formation of the Medical Engineering Department. This was in response to the desire of many of our faculty and of local research hospitals and medical foundations to jointly engage in engineering-centric technology development efforts for medical applications. We highlight the visionary research of the Caltech faculty who have come together to form this new department in the feature article in this issue of ENGenious.
Over the past four years, the faculty and I have implemented the first large-scale structural reorganization of the Division since its formation more than 100 years ago. The purpose of this reorganization was to further enhance the Division's effectiveness in teaching, research, faculty recruitment, and fundraising. The new culture of fundraising that we have introduced has involved the creation of a system of multiple fundraising councils, composed of Caltech alumni, Institute trustees, and industrial and community leaders. Since 2009 we have raised over $140 million, including funds for 20 endowed graduate fellowships and seven endowed professorships.
One example of the transformational power of this new culture of fundraising is the creation of the endowed Otis Booth Leadership Chair for the Division, made possible by a $10 million gift from the Otis Booth Foundation. Franklin Otis Booth Jr., the late husband of Foundation President Lynn Booth, established the foundation in 1967. Booth became an investor, newspaper executive, rancher, and philanthropist after graduating from Caltech in 1944 with a BS degree in electrical engineering. This endowment will support time-sensitive research that is too high-risk for most traditional grants and teaching innovations—including future online courses co-taught by EAS faculty and JPL scientists—as well as providing increased funding for faculty recruitment and cutting-edge research equipment. Another example of the opportunities created by this culture is the establishment of the Caltech Resonate Awards to honor breakthrough achievement in energy science and sustainability. This was made possible by a generous gift from Stewart and Lynda Resnick.
In looking forward to the new academic year, one of my priorities is to explore international collaborations that are especially appropriate for the size and concentrated excellence of Caltech. For instance, last year the Indian Department of Space and the Indian Space Research Organization (ISRO) established a graduate fellowship at Caltech in the name of Caltech alumnus Satish Dhawan (Eng '49, PhD '51), who is a pioneer of India's space program. This gift honors Dhawan and recognizes the historical connections between engineers and scientists in the United States and India. Another international opportunity we created last year was the Vest Scholarship, named after my friend and colleague Charles M. Vest and intended to bring high-powered international graduate students to Caltech for one year to work with Caltech faculty on grand challenges for engineering identified by the National Academy of Engineering (NAE).
Finally, the Earle M. Jorgensen Laboratory, which was featured in last year's ENGenious, has received LEED platinum certification in addition to architectural awards from the American Institute of Architects, the Westside Urban Forum, and the Los Angeles Business Council. We are also excited to be nearing the start of the renovation of the Thomas Laboratory—I encourage you to view some of the architectural renderings for this project on the inside back cover.

Rarest Flower: This picture is a false-color scanning electron microscopy image of a collapsed carbon nanotube (CNT) pillar. The pillar is fabricated using chemical vapor deposition process on a substrate that has been pre-coated with a thin-film iron catalyst. Here, the catalyst layer is patterned with a periodic array of five-pointed stars. Subsequent to the growth process, this pillar is subjected to oxygen plasma treatment and capillography process. The role of oxygen plasma treatment is twofold: to functionalize each CNT with oxygenated groups and to etch the outer portion of the pillar. The capillography process is performed to collapse CNT pillars radially inward.
Generally, the etching process of CNT pillars by oxygen plasma treatment occurs isotropically in both lateral and vertical directions. However, the presence of CNT entanglement at the tip of the pillar creates a directional variation in the etching process. Thus, the mid-section of the CNT pillar is typically etched faster than the tip. The mid-section of the CNT pillar is further collapsed when it is subjected to capillography process. The flower-like shape is then formed due to the mismatch in diameter of the mid-section and the tip of the CNT pillar.
A combination of oxygen plasma treatment and capillography process is utilized to reduce the size and to improve the CNT packing density of CNT pillars subsequent to the growth process. Such modification is deemed necessary whenever the CNT pillars are used as scaffolds for composite microneedles. These microneedles have been envisioned for use in a rapid self-administered and painless drug delivery system, replacing the commonly used hypodermic needles.
The Caltech Division of Engineering and Applied Science consists of seven departments and supports close to 90 faculty who are working at the edges of fundamental science to invent the technologies of the future.
