Smorphacade

“The Smorphacade project is the first-of-its-kind collaboration between structural engineers, wind engineers and control engineers to turn a passive building façade into a live façade that protects the building against wind load and turbulence,” said Alice Alipour, associate professor of civil, construction and environmental engineering. Alipour leads a team that’s combining a network of pressure, velocity and acceleration sensors strategically positioned on building surfaces. When excessive vibration-causing flow conditions are detected, the Smorphacade will change surface roughness or smoothness to mitigate inter-story building movements.

Virtual Reality, Real Cybersickness

Cybersickness. No, it’s not being tired of the constant stream of new emails in your inbox. It’s the physical illness some people feel in virtual reality environments. Angelica Jasper, a Ph.D. student in Humana Computer Interaction, is studying how to prevent VR users from experiencing nausea, disorientation, and oculomotor strain.

Engineering sustainable, safe food from the field to the table

A team led by Hongwei Zhang, professor of electrical and computer engineering, has developed CyNet, an open-source, wireless networking infrastructure to support data-driven research. CyNet takes on the challenge of quickly and reliably transmitting agricultural measurements from the crop field to plant scientists’ computers – and serves as a prototype for bringing much-needed broadband to rural areas. Food safety testing usually takes place in the lab by highly training technicians, but on-site, real-time, low-cost monitoring is our best tool to stop contaminated food from reaching consumers. Carmen Gomes, associate professor of mechanical engineering, is making key innovations in biosensor fabrication and system design to ensure food safety.

Boeing Undergraduate Research Fellowship program takes flight

A new partnership with Boeing pairs undergraduate students with College of Engineering faculty and Boeing engineers to get hands-on research experience in cutting-edge projects in aerospace engineering, cyber security, autonomous systems, machine learning and more. “The Boeing Undergraduate Research Fellowship has created opportunities for undergrads to learn research by doing, work on high-impact projects, and get familiar with the intellectual property considerations of industry-backed research,” said Arun Somani, associate dean for research, Anson Marston Distinguished Professor in Engineering, and Philip and Virginia Sproul Professor in Electrical and Computer Engineering.

All about (data) connections: Precision conservation at the FEW nexus

Amy Kaleita, professor of agricultural and biosystems engineering, works at the intersection of food, energy, water and land use systems on data-driven precision conservation. Where there’s good soil and water data, she uses it, where there’s gaps in the data, she creates new models to estimate variables, and where there’s neither existing data nor a good model, she designs new sensing systems. And in all cases, Kaleita says she focuses on the connections – between complex natural systems, land uses and more – to protect our land and water.

Beyond batteries: New energy systems for a sustainable future

Incremental improvement is the goal of most battery research programs, but Cary Pint isn’t looking to build on existing ways of doing things. He’s out to create new systems of energy storage for a sustainable future. “My background brings together diverse experiences in both academia and industry and across many different disciplines. That allows me to approach these problems in new and unique ways – and I’ve built a multidisciplinary research team that does the same,” said Pint, Charles Schafer (Battelle) Chair in Engineering and associate professor of mechanical engineering.

Storage systems keeping data safe

Storage systems are the fundamental computing building block of our modern lives – and like physical building blocks, computer storage systems must function well in fair weather as well as sudden disturbances to keep data safe.

Sensors for closed systems open up possibilities in biotech

Ask Nigel Reuel about his research and you start to hear a pattern in how he describes his goals: “merging,” “collaborating,” “tying together,” “multidisciplinary.” Look at his career, and you see how he’s combined industry experience with in-the-lab creativity to create engineering innovations. “When I was at DuPont, one of my roles was a technology scout, looking around for the best ideas that would be useful for core businesses, and I started to see that many other companies were looking to university professors as well to develop the next wave of innovation,” said Reuel, assistant professor of chemical and biological engineering. “I realized where I could really push innovation and bring together teams of strong players would be joining academia.” Since coming to Iowa State, Reuel has succeeded in becoming the “entrepreneurial professor” he set out to be.

Engineering probiotics to fight illness

Our gut microbiome – a collection of complex and varied microbes – is important to our health far beyond our digestive tract. We know that too much “bad” bacteria can make us ill, but the opposite may also be true. Engineering “good” bacteria could be key to fighting illness. Mansell seeks to overcome one big challenge of introducing new good bacteria into the gut environment: When we eat foods rich in live cultures or take a supplement that introduces probiotics into our gut, then the probiotics themselves need something to feast on if they are to multiply and remain in place.

Filling the GAPS

Could graduate students build more than just research skills during their thesis projects? An interdisciplinary project led by Cyclone Engineer Shan Jiang aims to address this question through the first of its kind Graduates for Advancing Professional Skills (GAPS) program.

Expect Turbulence

Paul Durbin is creating new hybrid, adaptable computational models to predict transitions from laminar fluid flow to turbulence and to simulate the turbulent flow. Right now, engineers rely on two types of turbulence modeling: average flow calculations, which offer high efficiency, but less detail, and eddy-resolving calculations, which offer more detail about turbulence, but take more time and are often cost prohibitive.

Growing Collaboration: Optimization and machine learning meet plant genomics

Lizhi Wang, associate professor of industrial and manufacturing systems engineering, is applying process optimization and machine learning to improve crops’ adaptability to new environmental conditions. Wang, also an Iowa State Plant Sciences Institute Faculty Scholar, serves as the principal investigator for the project supported by a $2 million grant from the National Science Foundation.

3-D Printing Concrete Rapid Solutions with a Steady Material

If 3-D printing can quickly and efficiently create machine parts, could it also quickly and efficiently create bridges and buildings after natural disasters? Kejin Wang, Wilson Professor of Engineering in civil, construction and environmental engineering, is leading advanced research in the emerging field of 3-D concrete printing. She aims to add 3-D concrete printing to civil and construction engineers’ toolbox.
