Aurora
Medical Grade Pepper’s Ghost Display (Bishop Visual)
January 2019 – Present
Description:
When Bishop Visual unveiled our large-scale prototype to researchers, they were intrigued by the possibility of conveying three-dimensional concepts in a more immersive way, and were interested in utilizing the technology in their laboratory. After the conference, I led in the design of a hardware system that addressed the feedback we received. This device, dubbed Aurora, incorporates a touchscreen monitor and a computer into its chassis to create a fully-integrated solution for displaying 3D images. I designed and manufactured laser-cut and 3D printed components using parametric CAD software to merge off-the-shelf electronics and hardware into a cohesive system suitable for professional applications. Since the completion of the initial device, we have gained additional feedback from consultants in the biomedical field, and refined the design to incorporate more robust materials and improve the manufacturability of the device. Additionally, to further development of the project, I have contributed to writing, editing, and submitting a Phase 1 SBIR grant application through the NIBIB. If accepted, this funding will help propel the development and commercialization of the project.
Design Features:
– Touchscreen monitor and powerful computer integrated into the chassis of the device
– Unique rotational mechanism allows the device to spin freely without tangling cables
– Robust Pepper’s Ghost display manufactured from high-performance materials

User-Friendly Pill Case
Oct. 2018 – Present
Description:
I live with epilepsy, and my condition is under control as long as I take my medication on time. This can lead to some anxiety, as forgetting to take pills on time can have a major impact on my life. Even when I’m 99% sure I have taken them, I need to carry my pills with me at all times so I can double check, and take them as soon as possible if I realize that I’ve forgotten. Pill cases that are currently on the market aren’t ergonomic, and require two hands to use, so I designed a pill case to fit into my hand, my pocket, and my life. The next release of this device will incorporate sensors and Bluetooth connectivity to allow users to automatically track when they have taken their medication, and receive notifications when they’ve forgotten. Additionally, for improved sustainability and visibility, one of the objectives of the project is to utilize injection molding to manufacture the pill case with polypropylene from recycled pill bottles.
Design Features:
– Rounded, ergonomic shape to fit in the palm of your hand
– Thumb wheel and door lever allow for one-handed operation
– Reversible day wheel allows for ambidextrous operation
Pax Mask
Alternative N95 Respirator
Mar. 2020 – Sept. 2020
Description:
At the beginning of the COVID-19 pandemic, there was a severe shortage of personal protective equipment (PPE) for healthcare workers. In March 2019, I joined the Mass General Brigham Covid Innovation Group’s PPE Working Group, where I developed a prototype of a 3D printed respirator body that could accept replaceable filter material with the same efficacy as an N95 filter. Through fit testing at Mass General Hospital and collaboration with the PPE Working Group, I further refined the design, but it became clear that a 3D-printed stop-gap respirator design would not be able to scale sufficiently to meet the growing PPE shortage. To address this dilemma, I began to work closely with Derek Pedersen to develop a modular respirator design that utilized a combination of rapid prototyping and traditional manufacturing techniques. A key feature of this design was the silicone gasket, which improved user comfort and allowed the mask to fit a variety of face sizes and shapes.
Design Features:
– Thermoformed PET-G respirator body
– Molded silicone face-seal for maximum comfort and adaptability
– Injection molded filter canister designed to maximize breathability
Accipiter Aerospace
Advanced Model Rockets
July 2020 – Present
Description:
While advancements in electronics, manufacturing, and material science have transformed the aerospace industry , model rocketry has been using the same materials and build techniques for decades. Assembly of the rocket is labor intensive and very sensitive to human error. If a single component, such as a fin, is damaged, the rocket will not be able to fly again without heavy repairs. In order to solve these issues, I designed rocketry components optimized for additive manufacturing to create a high performance modular rocket. The digital fabrication of the design ensures high accuracy and replicability of the components, allowing focus to shift from validation of flight hardware to development of payloads. The modular nature of the design makes it possible to optimize features of components, such as fin size, or nose weight, based on pre-flight simulations of flight characteristics. This project will accelerate the development of aerospace programs by providing a robust and replicable launch vehicle for hobbyists, university rocketry teams, and scientific researchers. Future development of the design will incorporate GPS tracking, live telemetry, motorized flight stabilization, and stabilized video.
