C-SPIN’s Fourth Annual Review Ushers in Final Year

C-SPIN recently began its fifth and final year.

The Center’s fourth Annual Review marked the beginning of its final lap. As always, the Review brought together all the PIs (37 total), most of their graduate students and post-docs (67 total), and a dozen industry representatives.

The formal presentations from the PIs revealed just how far C-SPIN has pushed the frontiers of spintronics science in the past four years – and all the promising technology that can be developed in the remaining year. In particular, C-SPIN scientists plan on building and testing several new spintronic computing devices in Year 5, some of which may be taken up by industry for more development. The students and post-docs also presented over 50 posters, all of which were reviewed by at least one industry representative.

As in some previous years, C-SPIN included “deep dive” sessions in the Annual Review. These sessions brought students, PIs, and industry representatives together to share research and ideas for moving the field of spintronic computing forward. For the first time, however, C-SPIN held pre-Review “focus session” workshops to promote focused discussion about two important spintronics fields: non-STT spintronic approaches to memory and non-Boolean/non-Von Neumann computing. According to participants, these workshops generated important directions for current and future spintronics research.

C-SPIN will host a fifth Annual Review in September 2017. The Review will primarily be a celebration of the Center’s achievements since 2012, but will also serve as a launching pad for future spintronics research and development around the globe – some of which will, no doubt, include University of Minnesota researchers and facilities.

In Memoriam: Prof. William T. Peria

The Department of Electrical and Computer Engineering mourns the passing of Prof. William T. Peria.

Prof. Peria was an ECE faculty member from 1960 to 2001, and was department head from 1970 to 1976. He left an indelible impression on all who met and interacted with him, be they students or faculty members. Since news of his passing, remembrances have been pouring in, and the sentiment that every email or note has expressed is one of gratitude for having known him. He is remembered as being unfailingly kind, a mentor, and a tough but dedicated teacher.

As a teacher, he had high expectations from his students, and was committed to providing them with the best learning experience. About his reputation as a tough teacher, Prof. Beth Stadler has this interesting story to share: “An alumnus from Honeywell led a senior design group with me one semester.  Now successful and paying forward (by helping current students), he ran into Bill one day. He said, “Prof Peria, you were on my thesis committee.” Bill replied, “Oh, give you a hard time, did I?” The alumnus tipped his fedora and said, “Yes, and for that I thank you!” Similar stories about Prof. Peria as an exacting but nurturing teacher abound.

Faculty remember him as a great colleague, a generous mentor, and a friend who freely shared his time and resources. Prof. Ned Mohan remembers being hired in 1975 as an assistant professor, when Prof. Peria was the head of the department. Despite his own research field being different, he introduced Mohan to as many Twin Cities power communities as he knew.

Like Peria, Prof. Doug Ernie too worked with vacuum systems and gas discharges, and he remembers having frequent discussions over their experiment results or problems with equipment. It was in the course of the many lunches at Campus Club, where Prof. Peria regularly held a table, that Ernie learned about his involvement in the development of standard surface diagnostic techniques, and the establishment of Physical Electronics in 1969. In Ernie’s words: “I can’t thank him enough for all his help, advice, and friendship over the years. He will be greatly missed.”

Prof. Peria is also remembered for being an unassuming individual, who had a deep dislike for awards. Prof. Bill Robbins notes: “I recall him on several occasions offering the opinion that the paychecks we receive for doing our jobs serve as faculty awards.”

Of his generosity, Prof. Rhonda Franklin has this to say: “He was one of the first in the department to help me set up to conduct porous silicon research and generously shared resources he had in his lab.” On a similar note, Prof. Stadler comments how he gave her spare parts for a sputtering system in her lab, when it needed repairs, during her early days in the department when she had no funding of her own.

In all the remembrances coming in from faculty, there is the constant note of Prof. William Peria being a friend and a principled man. An instance recounted by Prof. Jim Leger illustrates this: “I remember walking to the Campus Club with him one cold winter lunchtime. We all stopped at the stoplight to cross Washington Ave.  There being no cars in sight, we started to walk across the street, against the red light.  At the other end, we looked around to see Bill still standing at the light.  We waited for him to cross when the light turned green. When he rejoined the group he said, “You know, if you don’t show concern for the law in front of these students, they are never going to respect it.” 

Prof. Jim Holte’s words probably best represent the department’s collective sentiment: “Bill was my best friend. No one can replace him.”

To honor the work and legacy of Prof. Peria, ECE faculty will be meeting at the Campus Club on Friday, Feb. 10, at 4:30 pm.

Prof. John Sartori Wins NSF CAREER Award for “Application-specific Power Management”


Prof. John Sartori has been awarded the CAREER award from the National Science Foundation’s Faculty Early Career Development (CAREER) Program. This is one of the most prestigious awards instituted by the NSF to recognize and support faculty early in their careers who show the potential to “serve as academic role models in research and education and to lead advances in the mission of their department or organization.” The CAREER award ranges from $400,000 to $500,000 (depending on the research area) and is disbursed over a 5-year period.

John’s research will focus on the development of novel techniques for application-specific power management that will reduce the power consumed by general purpose processors (GPPs) without reducing performance. Low-power GPPs are used extensively in several key current and emerging applications such as smart sensors, health monitors, wearable electronics, and the internet of things. The energy efficiency of these systems determines essential characteristics such as size, weight, cost, reliability, and lifespan. Prof. Sartori’s research has the potential to significantly reduce power and energy requirements for emerging low-power systems, which could result in devices that weigh and cost less, but have greater reliability and a longer lifespan. His research also provides a non-intrusive way to improve the energy efficiency of existing systems without re-designing system hardware or software.

Prof. Sartori will use the NSF award to continue to integrate his research goals with his educational activities, and provide research experience for undergraduate and graduate students. Educational activities will center around project-based learning experiences that will allow students to directly engage and contribute to knowledge creation in the project, while also learning key engineering and research skills. Sartori has consistently refreshed courses that he leads with substantial project-based learning components that are essential to helping students not only learn critical engineering skills and concepts, but also put them into practice. He has included a project symposium or design show in each class that he teaches that afford students a platform to deploy what they have learned, and also develop soft skills such as presenting their work to a public audience. EE 1301 is an example of this endeavor. Required of all students aspiring to enter the electrical and computer engineering majors, John helped to redesign the course, and it now introduces students to the emerging field of internet-of-things (IoT) devices that are quickly becoming the most abundant type of computer part manufactured and deployed today. Under the new course design, students create IoT devices, under the broad requirements that these devices connect to the Internet, have the ability to sense the environment, and change the environment as appropriate. The course culminates in a design show which provides a means of community outreach to engage K-12 students as well as other members of the university and the community at large. The NSF CAREER award will also allow Prof. Sartori to engage in global outreach by introducing education on IoT technology to a Kenyan  educational initiative on best practices in farming.

John earned his doctoral degree in 2012 from the University of Illinois at Urbana-Champaign, and he joined the University of Minnesota soon after. He is the recipient of several best paper awards, and the author of three invited conference papers, besides authoring over 30 regular conference papers. His research contributions include the creation of automated techniques for approximate hardware and error-resilient software design, study of peak power management for many-core processors, exploration of CAD and architecture methodologies for energy-efficient multi-modal processing, and the feasibility and benefits of computing with programmable stochastic processors. His leading research interests include extreme energy efficiency, stochastic computing, and exploiting parallelism and scalability.

Hamza Farooq in Nature’s Scientific Reports

Doctoral candidate Hamza Farooq from ECE, in collaboration with other researchers and faculty from CMRR and the Department of Computer Science and Engineering, has shown that intricate brain tissue microstructure imaging can be obtained using diffusion MRI (dMRI) data. The paper titled “Microstructure Imaging of Crossing (MIX) White Matter Fibers from diffusion MRI” published in the Nature research journal Scientific Reports, addresses the key question of imaging crossing white matter fibers with their detailed tissue structure. It presents a new and versatile technique to fit advanced biophysical models to dMRI data, thus identifying features such as axonal orientation dispersion, density, and diameter in complex white matter fiber configurations. The study not only provides a flexible computational framework that enables evaluation and classification tissue analysis, but also improves state of the art tissue biophysical models. Hamza is advised by Prof. Emeritus Tryphon Georgiou from ECE and Prof. Christophe Lenglet from CMRR.
