Osseointegrated Implant System
- Surgical Instrumentation
Developed for DJO Surgical, marketed as "POP." Involved in the development, testing, and release of surgical instrumentation used by surgeons to prepare residual limb, and assemble and implant the system into patient. The system is used for individuals with transfemoral amputation who are unable to wear prosthetic sockets due to heterotopic ossification, or other pain-causing conditions. The system works by installing an implant percutaneously into the residual femur. The system has been approved by FDA under IDE submission for use in clinical trial.
Spinal MRI Phantom
Designed for GE Healthcare. Responsible for design and testing of phantom device. The purpose of the device is to calibrate MRI machines by providing resolution inserts corresponding to various MRI calibration levels. The device also included a spine resembling that of the average 40-year-old male, which provides a healthy reference point for healthcare providers to use when diagnosing a patient. The spine and calibration inserts were removal, enabling a modular design which can be used for other types of inserts.
3D Printing Process Optimization for Lifelike Prosthetic Components
Process developed for Medical Art Prosthetics LLC. The purpose of the project was to source equipment and develop a streamlined pipeline for the development of custom prosthetic parts (ears, fingers, etc). The existing process involved large amounts of manual work (including creating a physical mold for the patient) and required the component to be shipped to multiple facilities, which was costly and time consuming. Due to limitations of their molding materials, they were only able to produce rigid prostheses which were unnatural and uncomfortable to the patient. Thus, the project involved selecting a 3D scanner to scan an image for the patient, developing a CAD model of the scan, and selecting a 3D printer with multiple extruders so that multiple materials could be used - all of which could be completed in-house for the client.
LIDAR Mobile Robot
The goal of this project was to develop a mobile robot which was capable of avoiding a series of obstacles and return to it's original trajectory, while moving to a desired endpoint. Objects in a room were detected using LIDAR SLAM system and data were processed using a Raspberry Pi microcontroller. The robot also utilized a Lyapunov-based controller to account for trajectory-tracking error caused by the wheels slipped along the ground.
Robotic Art Arm
Designed for Dr. Chris Luzzio at UW Health Neurology. The purpose of this project was to develop a robotic arm and controller which would allow a patient with multiple sclerosis to paint on a canvas despite their limited mobility. The robotic arm consisted of 5 degrees of freedom. When the canvas was placed in a predefined location, the user was able to control the robotic arm using a joystick and small touchscreen.
Self Cleaning Toilet
Designed for Kohler Company, marketed as "ContinuousClean" system. Involved in the development and evaluation of multiple design prototypes and cleaning schedules. This included experimental design and completion for bacterial quantification for each system. The system works by automatically dispensing and distributing cleaning product with every flush, so that the consumer never has to clean the toilet.
Stem Cell Filtration System
Developed for the Saha Research Lab at the Wisconsin Institutes for Discovery. Induced pluripotent stem cells (iPSCs) are stem cells that are reprogrammed from somatic cells such as epithelial (skin) cells, and can be used for the treatment of cancers, diabetes, and Alzheimer's. One challenge with obtaining these types of cells is that they require patients to travel to research laboratories, which may not be possible for some individuals living in remote areas. However, human urine typically contains small numbers of renal epithelial cells which may also be reprogrammable. Thus, the purpose of this project was to develop a device and kit which could be sent to patients in remote locations to easily collect cells from their urine samples prior to shipping the kit back to the lab. The device was also required to create an environment that permitted the epithelial cells to survive for up to 7 days in transit.
Chess Game
Developed for a Java class project. We were asked to develop an interactive game in Java. I developed a chess game with a two player mode and a play against the computer mode. The computer mode allowed the user to select an easy, medium, or challenging game, or to play continuously. The continuous game setting would adjust the difficulty of computer game play depending on user performance.
