Janet Roveda, the College of Engineering's 2017 da Vinci FellowProfessor Janet Roveda has been named the 2017 da Vinci Fellow for the UA College of Engineering for her far-reaching research contributions.

This year’s nominations focused on faculty whose roles in campuswide research have generated major funding for the entire University of Arizona.

Roveda has brought millions to the UA in funding – $2.3 million in the last six years alone – and forged collaborations within the College of Engineering and among the UA colleges of science, optical sciences, education and medicine.

One frequent collaborator is Linda Powers, Thomas R. Brown Distinguished Chair for Bioengineering, with whom Roveda is developing mobile devices for detecting pathogens in blood and designing technologies for higher-resolution mammography image processing.

“She is amazing to work with,” said Powers.

Roveda's fellowship includes a one-time grant of $10,000 to support either research or teaching projects.

Honored alongside Roveda in a special reception for da Vinci Circle members were 10 da Vinci Scholars – two of whom are ECE students. Congratulations go to David Malbouef and Seth Werly.

The symposium gave students an opportunity showcase their research and share ideas in an open, interactive forum with faculty, students and staff.

The event featured 44 master's and doctoral students, and fifth floor filled quickly with interested attendees.

  • Best Poster Design, for creative expression of a topic: "Proof of Reliability in Cloud Storage," by Li Li and Loukas Lazos (adviser)

"I really enjoyed learning from the students about their research," said Kelly Potter, UA professor of electrical and computer engineering and optical sciences. "Two of my students presented posters at the symposium, and they both reported that they really enjoyed the event both for the opportunity to interact with their peers and learn about research being conducted across the department, and because of the one-to-one interactions with faculty."

The CAT Vehicle goes for a spin during the annual CAT Vehicle ChallengeECE's Cognitive and Autonomous Test, or CAT, Vehicle got another chance to hit the road on April 23-25, with the help of students from the U.S. and abroad.

The UA's CAT Vehicle Challenge invited student teams to write, analyze and re-write code that ultimately can "drive the driverless car." Of particular interest is whether the code creates a safe test.

More than 20 teams participated in the three-day "hackathon-style" challenge, the majority comprised of UA students. Four teams arrived from out-of-state, traveling as far as Chile and Switzerland, to compete.

ECE associate professor Jonathan Sprinkle is a co-principal investigator on the challenge, which exists as part of NSF's multi-campus Cyber-Physical Systems Virtual Organization.

The event was sponsored by the National Science Foundation and MathWorks. Check out more photos from the challenge, courtesy of Arizona Daily Star and photographer Mamta Popat.

Cover of Proceedings of the IEEE featuring Hao Xin's researchResearch by ECE professor Hao Xin was featured on the cover of an April 2017 special issue of Proceedings of the IEEE, a monthly peer-reviewed journal published by the Institute of Electrical and Electronics Engineers.

The publication highlights work by Xin and postdoctoral researcher Min Liang on 3-D additive manufacturing techniques for electromagnetic components, as illustrated by the cover image: an X-band WR-90 waveguide feed for transmitting energy and an Eaton lens, used in high-frequency antenna systems.

The lens was produced in Xin's UA Millimeter Wave Circuits and Antennas Laboratory, which was one of the first to adopt 3-D printing techniques to make metamaterials – engineered materials with properties not found in nature that are designed to affect electromagnetic waves and sound in ways impossible to achieve with traditional materials.

The lab also uses 3-D printers to make a range of conventional things, such as regular antennas and integrated circuits.
