Academy of Radiology Research honors Sabee Molloi as Distinguished Investigator
Sabee Molloi, professor of radiological sciences at UCI, has been named a Distinguished Investigator of the Academy of Radiology Research. The honor recognizes imaging researchers for their significant contributions in the field of medical imaging. Molloi, who holds joint faculty appointments in biomedical engineering and electrical engineering, focuses on developing novel diagnostic imaging techniques for breast cancer and cardiac disease.
At UCI, his research group has developed a dual-energy mammography technique that takes images of a breast at different energy levels to measure tissue density, which is important because women with dense breast tissue are four to five times more likely to develop tumors. And partnering with Carlos Iribarren, a research scientist from Kaiser Permanente, he is assessing whether breast arterial calcification detected by mammography can be used to gauge cardiovascular disease risk. For this effort, the two have received a $6.8 million grant from the National Heart, Lung & Blood Institute to study mammography-identified calcium buildup in breast arteries in more than 5,000 African American, Latino, Asian and white women at three Kaiser Permanente medical centers in Northern California. The researchers will test whether these calcifications correlate with several cardiovascular disease risk factors. A technique to accurately measure breast arterial calcium mass was developed in Molloi’s laboratory.

Squid Skin Protein Could Improve Biomedical Technologies, UCI Study Shows
Conductivity could charge up futuristic disease treatments
The common pencil squid (Loliginidae) may hold the key to a new generation of medical technologies that could communicate more directly with the human body. UC Irvine materials science researchers have discovered that reflectin, a protein in the tentacled creature’s skin, can conduct positive electrical charges, or protons, making it a promising material for building biologically inspired devices.
Currently, products such as retinal implants, nerve stimulators and pacemakers rely on electrons – particles with negative charges – to transmit diagnosis data or to treat medical conditions. Living organisms use protons, with positive charges, or ions, which are atoms that contain both electrons and protons, to send such signals. The UCI discovery could lead to better ion- or proton-conducting materials: for instance, next-generation implants that could relay electrical messages to the nervous system to monitor or interfere with the progression of disease.

Mentorship Program Makes a Strong Impression in its First Year
At a spirited June event in the Student Center’s Pacific Ballroom, a group of students from both the Samueli School of Engineering and the Donald Bren School of Information and Computer Sciences gathered with their mentors to celebrate a successful end to the two schools’ inaugural Undergraduate Mentorship Program.
In its first year, the Undergraduate Mentorship Program focused primarily, though not exclusively, on pairing up female engineering and ICS students with mentors in a variety of high-tech businesses. The proportion of women in STEM fields (science, technology, engineering and mathematics), both in academia and industry, continues to lag behind that of men. This is why the program began with a focus on women.
Linda Smart — senior director of research and development informatics services at Allergan, a UCI alumna and a member of ICS/Engineering Diversity Committee — was instrumental in the launch of the mentoring program.
“I had a real personal interest,” Smart says. “It’s a way for me to sort of reach back in time, think about who I was as student, and say, ‘How can I give young students the benefit of my experience?’”

Engineering Doctoral Student’s Dissertation Selected for Special Publication
Nasrin Nasrollahi’s dissertation has been selected by scientific publisher Springer for its Springer Theses series. Nasrollahi has finished her doctorate in civil and environmental engineering working with Distinguished Professor Soroosh Sorooshian and Associate Professor Kuo-lin Hsu in the Center for Hydrometeorology and Remote Sensing (CHRS). Theses in this annual publication are selected for their scientific excellence and impact on research. They must be nominated and endorsed by two recognized specialists.
The CHRS provides global, near real-time rainfall information using remote sensing technology. With a mathematical modeling approach, the center processes different electromagnetic signals picked up by satellites from clouds and storm systems and converts them into rain estimates. Used primarily by government officials and climate researchers for flood forecasting around the world, the information is also accessible to the public via the Internet.
Nasrollahi’s dissertation research involved improving the quality of precipitation estimation information that is provided by the center. She applied a multi-satellite, multi-spectral approach, incorporating data on clouds and rainfall from two recent NASA satellites and using machine learning techniques to develop a better estimate of rainfall. She also added a filter to reduce false rain signals in the data, which significantly improved the results.

UCI Engineering Postdoc Receives Prestigious Fulbright
Dustin McLarty, a postdoctoral researcher at the Advanced Power and Energy Program, will take what he’s learned working on UCI’s micro-grid power supply to Italy, on a Fulbright scholarship.
Sponsored by the U.S. government, the Fulbright Program offers highly competitive, merit-based grants for students and young professionals to study, conduct research or exercise their talents abroad. Founded by United States Senator J. William Fulbright in 1946, the Fulbright today is the largest U.S. international exchange program. It currently awards approximately 1,900 grants annually in all fields of study and operates in more than 140 countries. It is designed to increase mutual understanding between the people of the U.S. and people of other countries.
“UCI has one of the most cutting edge micro-grids in the world,” says McLarty. “It provides the campus electricity, cooling and heating with close to 99 percent self-generated power, almost none of the energy is coming from Southern California Edison.”
A micro-grid is a similar but smaller version of the traditional power grid and consists of power generation, distribution and controls such as voltage regulation and switch gears. Micro-grids integrate renewable sources of energy such as solar, wind power, hydrology, geothermal, waste-to-energy, and combined heat and power systems. They can operate on their own or be connected to the traditional grid, and they have a closer proximity between the power generation and the power user. UCI’s micro-grid integrates solar, fuel cell, thermal and natural gas to serve the campus’s needs.
McLarty’s research has to do with leveling out the intermittencies involved with a grid that relies on renewable sources of energy. “We put all these new energy sources on the grid and they don’t behave like our old ones, so we have to come up with a mix of new technologies that can interface, store and deploy the renewables in a way that levels out the power supply.”

Student Transportation Engineers Examine Joshua Tree Congestion
UPDATE 5-22-14: UCI transportation engineers win ITE Student Chapter of the year for Southern California section, besting Cal Poly Pomona and UCLA for the top spot.
UCI’s student chapter of the Institute of Transportation Engineers (ITE) heads to the ITE Southern California Section Student Competition this week where the students will present results from their Joshua Tree National Park Transit Feasibility Study.
The National Parks Conservation Association commissioned the UCI students, primarily civil and environmental engineering seniors, to study the feasibility of establishing a shuttle transit system to alleviate traffic and parking congestion for visitors to Joshua Tree. The students were mentored by ITE faculty adviser Professor Stephen Ritchie and doctoral student Sarah Hernandez.
“This is the most ambitious project yet undertaken by our student chapter, and it provided an outstanding opportunity for students to work on complex real-world problems and gain skills that will be invaluable for their future careers,” says Ritchie. “ Our chapter has placed first and second in the annual ITE Competition in the last three years, and while we’re naturally hoping for a place on the podium this year, most of all I’m extremely proud of the dedication, professionalism and team effort of our chapter.”

UCI Engineers Make Music with Class Project
Who knew that making music would become essential to the mechanical engineering curriculum?
For six years now, all UCI mechanical engineering seniors have taken a required course that has them designing, building and testing a music box. Not your ordinary jewelry-storing, ballerina-twirling, dresser-adorning music box, but a geometrically shaped, painted, stackable module that, with the drop of a metal ball, plays two seconds of original music. When the boxes are placed on top of one another in a tall tower, they are designed to play as a round. The first year, the assigned song was “Row, Row, Row Your Boat.”
Professor Derek Dunn-Rankin came up with the idea. Students in his class often start by deconstructing a thermo-electro-mechanical device, a hair dryer for example, to see how it works. As they move on to the musical box stack project, students are grouped into teams of four or five and assigned a number. Teams receive a set of parts that are sufficient to build a minimally functioning music box – some plywood, dowels, a microprocessor, an amplifier, wires, a switch, a servomotor and a speaker – but they are free to modify or replace any of the parts to improve the box’s performance. Although each person in the group is responsible for one element of the device, the students must all work together to create a functioning music box. Typically, there is a structures person, a programmer, one who works on lighting and servos, and someone who creates the sound and mounts components. There is overlap, but everyone has a core responsibility.
Dunn-Rankin chose this challenge for three reasons. First, it’s cooperative rather than competitive. “All of the head-to-head design competitions are great for energy and enthusiasm, but they can mistakenly encourage secretive design rather than expansive design, and it is the latter that leads to high performance,” says Dunn Rankin, Mechanical and Aerospace Engineering Department chair. “In this class, students are free, even encouraged, to learn best practices from their colleagues and to implement them.”

Prominent Materials Science Physicist to Join UCI Faculty
Xiaoqing Pan will oversee new $20 million research institute
Xiaoqing Pan, an internationally recognized researcher in the physics of materials, will join the UC Irvine faculty and lead a $20 million initiative to establish a world-class electron microscopy and materials science research facility.
The Irvine Materials Research Institute will help foster discovery of new properties in potentially lifesaving and technologically important materials through characterization - probing the internal structure of a material's atoms. The institute will serve as an interdisciplinary nexus for the study and development of these materials, enabling such advances as better solar cells, sustainable batteries and semiconductors, and treatments for bacterial and viral infections.
The transmission electron microscopes to be set up at the IMRI use beams of electrons instead of light waves to image a specimen with atomic resolution. This method produces a more detailed view at substantially greater magnification than with any optical microscope. UC Irvine researchers will utilize these microscopes to examine biological materials (such as microorganisms and cells), large molecules, medical biopsy samples, metals, minerals, ceramics and the characteristics of various surfaces.
"UC Irvine is making an investment of $20 million to develop cutting-edge capabilities in transmission electron microscopy," said Howard Gillman, provost and executive vice chancellor. "Bringing Professor Pan here to lead this institute is a real triumph for us in the materials science area. The research facility will establish our national prominence in this field and broadly benefit our programs in engineering, physical sciences, biological sciences and medicine."
"The electron microscopy initiative and the IMRI at UC Irvine will provide me with new tools and great opportunities for potential collaborations with the many researchers on campus," said Pan, a physicist. "I am grateful for the chance to help shape the university's future development through a combination of assisting students, developing departments, establishing the institute and moving forward in my own research."

Jafarkhani’s Seminal Paper on Wireless Communications Technology Recognized
UCI Chancellor’s Professor Hamid Jafarkhani has been recognized by the IEEE for a paper he published 15 years ago. The IEEE Communications Society Award for Advances in Communication is given to an outstanding paper that opens new lines of work, envisions bold approaches to communications, formulates new problems to solve and essentially enlarges the field of communications engineering.
Jafarkhani’s paper, published in 1999, described his research on space-time block coding, a technique used today in wireless communication systems. Jafarkhani was working at AT&T Labs when he and his colleagues established the concept of space-time block coding and showed how to design codes for a wireless communications system with multiple antennas, such as Wi-Fi. Today, space-time block coding is a well-established field in communications, actively researched and widely used. This paper has been cited more than 1,000 times.
“It is an honor to receive such a prestigious award,” says Jafarkhani, a professor of electrical engineering and computer sciences and director of UCI’s Center for Pervasive Communications and Computing.
