Our undergraduate researchers come from a variety of majors within the Fulton College of Engineering and Technology and the College of Physical and Mathematical Sciences. Research projects in IMMERSE are collaborations between students from a range of disciplines and focus on a variety of topics, including microelectronics, photonics, and biomedical engineering.
IMMERSE student researchers are often listed as authors on conference presentations, and on any publications relating to their projects. Students are also heavily involved in the writing and submission of technical publications, and are given the opportunity to present their research at various conferences relating to their fields of study. This experience of writing and publishing technical papers in peer-reviewed journals is a great opportunity for students to learn the ins and outs of scientific research.
Below are highlighted just a few of the projects currently going on in IMMERSE. If you'd like more information on any of the projects listed here, please feel free to contact us at firstname.lastname@example.org or stop by any of our labs in the Clyde Building.
Recent IMMERSE Projects
Micropower Circuit DesignDr. Wood Chiang
Our lab has developed numerous microchips for wireless communications, bio sensing, imaging, and instrumentation. We are currently working on several exciting projects including a detector to sense dust on Mars, a receiver for autonomous vehicles, a phase shifter for satellite communications, an analog-to-digital converter for ultra high-speed wireless communications, an image sensor for bio sensing, an ion detector for a mass spectrometer, and many others. Our students learn fundamental circuit theories, simulation techniques, layout, and measurement throughout the project to enable them to succeed in graduate school and industry.
Wireless Network SecurityDr. Willie Harrison
Security of wireless communication links promises to be an important area of research into the next few decades due to the ease with which wireless signals can be observed by eavesdroppers. Physical-layer security is how we refer to efforts to secure these wireless networks that involve exploiting phenomena at the physical layer of a communications system, such as the noise in a channel, to bring about secure communications. This type of security tends to require no secret keys, and hence, may have application in networks where sharing a key is difficult (think the Internet of Things).
This project seeks to answer the question: Is it really possible to use noise and secret codes to secure a wireless network? Students will make use of software radios, channel coding algorithms, and signaling techniques to verify the limits of physical-layer security in indoor and outdoor networks. Most results in this area are of a theoretical nature only, making this hands on research very meaningful in shaping the future of physical-layer security research.
Biooptofluidics: Liquid-Filled Optical Waveguides for On-Chip Chemical AnalysisDr. Aaron Hawkins
Optofluidics is one of the most exciting new areas in the optics field. Our research concentrates on optofluidic waveguides which can confine light in very low refractive index materials like water. Using these structures, we are able to probe fluids containing biologic particles such as viruses and DNA strands. We collaborate with chemists and biologists at BYU, academic research groups at other universities, and commercial companies. We are currently working on rapid tests for virus infections like Ebola and Zika and bacterial infections like the very dangerous drug-resistant bacteria strains which are becoming a bigger and bigger health risk. Our end goal is the development of a portable instrument which can provide test results in less than one hour for many different virus and bacteria strains.
Our group concentrates on the microfabrication of sensor chips used for bioparticle detection. This work is carried out in the BYU cleanroom using silicon wafers. The image on the left below show some of the sophisticated waveguides and microchannels we have built on the microscale. A completed sensor chip is shown on the right.
Concrete Bridge Deck ScanningDr. Brian Mazzeo
Infrastructure deterioration is a pressing problem facing modern societies. In particular, reinforced concrete bridge decks are susceptible to corrosion because of frequent application of deicing salt during winter months. The objective of this research is to develop fast, accurate scanning solutions using electrochemical and acoustic techniques to rapidly evaluate the condition of bridge decks.
FPGA Design ToolsDr. Brent Nelson
Custom computing architectures that employ FPGAs have been shown to provide significant improvements in computational performance and energy efficiency over traditional programmable processors. These benefits are possible due to the ability to customize a hardware circuit to a single computation and to replicate this computation many times. These computational benefits, however, are limited to those hardware circuit designers who have the skills to design FPGA circuits. This project is investigating techniques and tools for improving the productivity of FPGA design. A variety of tools have been created at BYU to facilitate FPGA design productivity including JHDL, RapidSmith, TINCR, and EDIFTools. RapidSmith is a research-based, open source FPGA CAD tool written in Java for modern Xilinx FPGAs. Based on XDL, its objective is to serve as a rapid prototyping platform for research ideas and algorithms relating to low level FPGA CAD tools.
UAV CoordinationDr. Cammy Peterson
Technological advances related to unmanned aerial vehicles (UAVs) has enabled the use of UAVs for a plethora of real-world applications such as package and medical delivery; infrastructure inspection; environmental sampling; and search and rescue. The objective of this research is to design algorithms that enable cooperation between many UAVs. UAVs working cooperatively together will achieve much more than a vehicle acting independently.
Fiber Bragg Gratings Interrogation for Composite Impact SensingDr. Stephen Schultz
Fiber composite materials are valuable for their lightweight and high-strength capabilities. For this reason they are being used in the construction of automobiles, bridges, and cargo vessels. However, shock, impact, or stress may cause internal damage to the materials that lead to significant reductions in component lifetime and result in disastrous failures. Fiber Bragg gratings (FBG) sensors react to environmental changes such as strain, which allow strain variations to be detected when the composite structure is subjected to impact events. A high-speed full-spectrum interrogation system is capable of recording detailed strain measurements of composite structures enabling better characterization of their failure modes.
Holographic Video MonitorDr. Daniel Smalley
The BYU/MIT holographic video is the world's first, low-cost holographic video monitor. This display differs from other electroholographic display technologies in that it can be driven from a commodity PC and boasts, full color, VGA resolution and video rate operation. This is made possible by the use of low cost waveguide-based spatial light modulators created as part of Dr. Smalley's PhD work.
Reliable FPGA ComputingDr. Mike Wirthlin
The growing use of satellites for complex communication, remote sensing, and surveillance applications requires significant computing resources. Modern satellites systems require far more computing power than every before and there is a great need to provide high-performance computing systems in space that are small, light weight, reliable, and consume limited energy. Field Programmable Gate Arrays (FPGAs) provide significant computing resources at the fraction of the power needed by conventional processor technologies. FPGAs, however, are sensitive to the ionizing radiation found in space environments and will not operate reliably unless appropriate radiation mitigation techniques are employed. This project is developing techniques for providing high-reliability, high-performance computing for space systems using FPGAs and other programmable technologies. This project is investigating novel reliability techniques, deign tools, computer architecture approaches, and software for providing the most reliable deployment of FPGA-based systems. The results from this work are directly applicable to high-reliabile computing in conventional environments on earth as well as within high-energy physics experiments such as the Large Hadron Collider (LHC).
