MilliporeSigma Projects
My third co-op through Northeastern University’s Cooperative Education Program was with MilliporeSigma, a global life science company focused on advancing scientific research and innovation. As part of the Research & Development team in the Life Science Biology franchise, I collaborated with engineers and scientists to design and prototype devices supporting filtration and laboratory applications. I led the development of a pneumatic controller to evaluate and optimize filtration performance, conducted mechanical and applications testing using instruments such as the Instron and burst testers, and gained experience in fluid sampling systems, pressure and vacuum control, and LabVIEW programming. This experience strengthened my skills in product development, experimental analysis, and interdisciplinary teamwork within a cutting-edge research environment.
- Modeled and laid out all components, built prototype assembly and fixture, mounted all components.
- Connected all valves to correct plumbing for air travel minimizing pressure drops and airflow travel.
- Wired and connected circuit for solenoid valves, pressure transducers, and flow meter.
- Coded in LabVIEW to control solenoid valves (open and close), pressure transducers (read and display data live, and write to an excel file), and a flow meter (read and display data live, and write to an excel file).
- Designed a fixture for the inverted welder and gripper assembly to support welding membranes onto 4 mL and 15 mL centrifugal concentrator housings.
- Created detailed CAD drawings for machining and procurement, set up the complete parts and assembly, and ordered all required hardware to ensure readiness for fabrication and testing.
- Designed a fixture for membrane cutting using various punches and dies on the Instron machine to capture accurate force–displacement measurements.
- Developed complete part and assembly models in SolidWorks and generated detailed machining drawings.
- Selected and procured all required hardware, then assembled and validated the final test setup for mechanical testing.
- Developed a testing protocol to evaluate the device’s thermal performance and determine its watt-hour operating limit.
- Configured National Instruments (NI) hardware and thermocouples for temperature measurement.
- Programmed a LabVIEW interface to acquire, live-stream, and log temperature data in real time.
- Performed data analysis and authored a detailed technical report summarizing findings and calculated watt-hour limits.
- Redesigned the in-lab stirred cell setup process to improve testing efficiency and data accuracy.
- Established serial communication between an Ohaus Scout Pro scale and a computer using MobaXTerm to verify data transfer.
- Developed a LabVIEW program to automate two solenoid valves, directing airflow into or out of the system based on real-time filtrate mass readings from the scale.
