Overview
In this project, conducted with Solid Material Solutions, I led the design and fabrication of the control panel for a High Temperature Superconductor (HTS) cabling line. This design used a central Automation Direct Productivity PLC for machine control and automation. This system governs the speed of four DC gearmotors through a dual rotary encoder feedback loop. I also developed a custom GUI for parameter setting and information display.
Objectives
Establish a cost effective control system capable of automating a precision manufacturing process.
Design a simple and user-friendly interface readily usable by operators.
Outcomes
Identified and implemented a control system using free and accessible software.
Proved the closed loop functionality of the system and improved operator user experience.
Overview
In this project, conducted with Solid Material Solutions, I led the end-to-end development of an automated conveyance and tensioning system designed for the lamination of 2G (REBCO) superconducting tapes. This multi-module production line utilizes precise servo gearmotors to pull multiple strips and HTS tapes through flux, solder, and quench stations under highly controlled loads. I developed the comprehensive control architecture for this system, which included a closed-loop tensioning strategy utilizing a Speed Limited Adjustable Torque (SLAT) configuration and real-time reel diameter monitoring via analog laser distance sensors. The automation logic was governed by an Allen-Bradley PLC and Kinetix 5500 servo drives, utilizing EtherNet/IP and Modbus TCP to interface with cantilever load cells, metrology instruments, and third-party process controllers. In addition to the electrical architecture, I was solely responsible for the mechanical design and fabrication of the pay-off and take-up units, incorporating custom reel mounts, inline optical measurement sensors for quality assurance, and mechanical safeguards to maintain strict steady-state tension limits.
Objectives
Lead the development of a functional conveyance system through its full lifecycle.
Organize and maintain a cross-functional team of multiple parties.
Develop extensive documentation for line maintenance and record keeping.
Outcomes
Guided the project through numerous unexpected scope and development changes
Identified viable cost reducing methods to ensure the feasibility of the line.
Ensured closed loop functionality through a comprehensive factory acceptance test.
Overview
In this project, conducted with Solid Material Solutions, I led the development of a fine wire drawing line designed for the fabrication of BSCCO (Bi-2212) superconducting ceramic composite wire. This unit uses a capstan drive drum for drawing and incorporates a dancing-arm automated dual speed tensioning system for pay-off and take-up of wire. I developed all automation for this system including die load data acquisition, lube temperature monitoring, rotary encoder length measurement, and automated wire feed with automatic stop in the event of a wire breakage. The circuitry was based on a hybrid model incorporating an Arduino microcontroller as well as relay logic for automation. I also developed all mechanical components used, including the unique dancing arm tensioners, drawing lubrication, wire cleaning, pay-off and take-up systems.

Overview
In this project, conducted at Wentworth Institute of Technology, I worked with a team of fellow senior mechanical engineering students to develop our own novel proposed method of renewable energy production. In our design, a neutrally buoyant hydrofoil composed of 3D printed inserts of varying infill density wrapped in an aluminum skin would be propelled by waves to turn two flexible impeller pumps whose motion would move water upwards to a siphoning reservoir serving as a water battery. When the reservoir reached a specific content of water, it would drain through a siphon and into a generator turbine to produce electricity. A scale prototype was constructed and tested using a wave pool of our own design.
Objectives
Identify a novel implementation of ocean energy production.
Create a prototype proof of concept with accompanying report to demonstrate feasibility.
Learn the end-to-end design process used in R&D engineering.
Outcomes
Created a subscale hydrofoil, pump, and siphon assembly to test the feasibility of the design.
Established the ability to pump water using a reciprocating hydrofoil.
Gave a presentation on the findings and successes of the project to peers.

Preliminary Design Report
Overview
In this project, conducted at Diamond Diagnostics, I was tasked with reverse engineering an existing electrolyte analyzer bottle tray to be redesigned in SolidWorks for duplication using 3D Printing. The full tray was broken down from one unit into 4 separate sections, each section was then printed, snapped together, and plastic welded into a singular unit for finishing at the company's in-house workshop.
Objectives
Create a low-cost replacement for an out of production bottle tray.
Ensure the design was reproducable for other customers.
Outcomes
Successfully created a rapid solution for a customer at short notice within a one month development period.
Refined the design to allow for future modifications to each of the four combined tray modules.
Overview
In this project, conducted with Diamond Diagnostics, I worked to assist in the development of an electrolyte analyzer autoloader system which would automatically load samples into the analyzer. My role in this project involved the development of initial block diagrams of the operating structure of the system as a whole, it also included the use of SolidWorks as a tool to develop prototype components which I then 3D printed using both an FDM and MSLA printer.
Objectives
Develop a feasible product prototype for eventual production.
Support a multidisciplinary team in the design process.
Outcomes
3D printed all prototype componentry and reduced lead time by running both the company 3D printer and my personal 3D printer simultaneously.
Developed a preliminary block diagram and overview documentation for presentation to the company finance team.
