Emulating a million neuron-brain in real time
- The goal of this project is to leverage advances in GPU-based and conventional computing platforms to simulate a synthetic biological brain comprising of more than a million connected neurons in real time.
- The design will be based on a specific model of a neuron that has been developed in AIMLab which enables the end user to create large-scale and stable neuro-dynamical system and also allows the user to experiment with different types of network-level dynamics. For this project, the student team will leverage a previously developed MATLAB toolbox to scale the user and visualization interface to support the construction and analysis of a million neuron system in real time.
- As a case study, the software will be used to construct a complete insect brain where the user can define the structure and connectivity of the network, along with different types of neurons.
- Suggested background: MATLAB, signal/image processing, basic neuroscience or neural network (optional)

Imaging DNA nanostructures and nanomachines using single-molecule, super-resolution microscopy
Design and construction of an ultrafast, single-photon-sensitive camera

In this project, the student will learn how to design and synthesize 3D DNA origami, how to design and build a chamber to actuate the origami, and how to image the position and conformation of the DNA using imaging technology in the Lew Lab. The specific project details are flexible and will be refined based on student experience and interest.

- Photons, the fundamental packets of light, can carry a wealth of information about a specimen of interest using their various degrees of freedom, including position, propagation direction, polarization, wavelength (energy), and time of arrival. In this project, the student will learn how to design and construct a photomultiplier-tube based ultrafast camera, capable of measuring the position and time of arrival of single photons (~500 ps resolution). The student will also design and test ultrafast readout electronics (~500 MHz sampling rate) for measuring these parameters and streaming them to a computer over gigabit ethernet.

Machine learning for image restoration
- In image restoration, the goal is to build algorithms for clearing images from undesired artifacts such as camera blur or sensor noise. The student will work on advanced algorithms for image restoration that are based on large-scale optimization and machine learning. We have developed a family of such techniques that use learned information, such as natural image features, to generate clean images from the corrupt ones. The student will have an opportunity to contribute to this exciting research area and learn the cutting-edge imaging algorithms.
- Skills Required: Familiarity with image processing and machine learning. Proficiency with MATLAB or Python.
Large-scale optimization for computational imaging
- Optimization algorithms play an essential role in modern computational imaging (CI). The choice of an optimization algorithm establishes whether a sufficiently good performance can be obtained in hours or in days. Increasingly, optimization is becoming large-scale due to modern systems dealing with millions of variables. The student will work on the development of novel advanced optimization algorithms for large-scale imaging. Computational Imaging Group (CIG) at WashU has recently developed several new algorithms and the students will contribute to this exciting area by extending our current results. Several applications will be considered, including biomedical image reconstruction and analysis.
- Skills Required: Proficiency with Python or Matlab. Familiarity with machine learning. Mathematical maturity to understand optimization algorithms and their analysis.

Combine radio tomographic imaging (RTI) with line speed of crossing measurements
- Radio tomographic imaging (RTI) estimates an image map of where people are in an area based solely on the changes that the people's bodies cause to radio waves in the area. RTI uses transceivers that transmit and measure received signal strength to measure these radio wave changes. However, RTI needs a high density of transceivers in the environment. Recently our research showed that we can accurately estimate the speed at which someone crosses a link line based on the measured changes. This project is to update RTI algorithms to include speed information, which we believe will result in RTI algorithms that are accurate even with low densities of transceivers.
Outdoor RSSI data mining
- Our lab has developed considerable expertise in environmental monitoring (localization, breathing and pulse rate monitoring) using RF measurements. We are now deploying tens of remotely accessible software-defined radios (SDRs) on towers and building tops in Salt Lake City, Utah. These can be controlled from anywhere and used to emulate current or next-generation wireless protocols. This project is to program a module that has the deployed SDRs to have a time-division protocol to transmit and receive, and measure the radio channel in between each pair of deployed SDRs. Radio channel measurements might include signal strength, Doppler, and/or channel impulse response. These measurements will change over time as the environment changes, for example, when the weather changes. This project is to characterize what kinds of changes are observed as a function of weather, and perhaps other environmental variables.

In this project, students can learn about modern data-integrated and learning-based approaches developed in the lab for synthesizing such optimal control laws for nonlinear systems and are also given the opportunity to apply these to different system models (including both simulations and physical implementations, such as quadcopters and other robotic systems).

Develop inkjet-printed stretchable sensor patch for wearable electronics applications
- Soft electronic devices built on ultrathin elastic substrates are suitable for a wide range of applications such as wearable devices and soft robotics. Our group has formulated various types of nanomaterial- and polymer-based electronic inks that can be patterned with high resolution and uniformity using a low-cost printing process. In this project, the students will learn how to fabricate stretchable electrode array and sensors (pressure, strain, temperature) using inkjet printing and characterize the sensor response curve. The student may also work on microcontroller board programming to allow the data from the sensors to be wirelessly transmitted to a smartphone app. Combining the above, a soft sensor patch will be prototyped and its functionality will be validated by using it to collect signals including heart rate, body temperature, and biopotential.
- Suggested background/courses: Analog and digital circuits, semiconductor devices, Arduino microcontroller board or Raspberry Pi.
Develop printed stretchable perovskite light-emitting diodes
- Flexible or stretchable displays have attracted a significant amount of interest recently in the consumer electronics market. The key components in such displays are organic or polymer light-emitting diodes (LEDs) built on plastic or elastic substrates. In the project, the student will work on formulating inks comprising perovskite nanocrystals dispersed in a conductive polymer. The ink will subsequently be used to fabricate stretchable LEDs using a low-cost inkjet printing process. The research aims to demonstrate LED devices that can be repeatedly stretched by at least 50% without reducing brightness. Once the printed LEDs are successfully demonstrated, they will be integrated to form a passive-matrix stretchable display.

Developing a wireless read-out interface to an electronic tooth
- In this project the student team will design a smart-phone based interface to acquire and process
sensor data recorded from an electronic tooth. The electronic tooth (or e-tooth) is collaborative
research project where the research team is developing a smart dental/oral implant that can continuously an over a long period of time, monitor the composition of the saliva for specific biomarkers.
- Currently, the e-tooth is wirelessly interrogated using a radio-frequency back-scattering method and uses a bulky laboratory equipment and uses off-line data processing. For this project, the student team will explore if the wireless read-out interface/analysis could be directly implemented on a smart-phone or using with minimal plug-and-play commercial off-the-shelf hardware.
