Canton, Massachusetts, United States

• Joined the Materials Innovation & Application Development Team for the Performance Additives Business after the company made a strategic pivot to focus on carbon nanotube (CNT) additives for Concrete & Batteries
• Extensive experience in the Printed Electronics Business, and impactful subject matter expertise of Concrete and Batteries
• Led identification of CapEx equipment to set up an operation to safely integrate CNTs into concrete, in addition to a QC Testing Lab to test the mechanical properties of CNT enhanced concrete
• Designed the Concrete Lab, which included: safety, regulatory standards, ergonomics, layout and workflow considerations
• Developed an innovative method to safely transfer and handle incoming CNT powders, scaling from gram quantities to multiple kilograms

Canton, Massachusetts, United States

• Focused the strategic vision of the Printed Electronics organization on Transparent Heaters and Transparent Antennas
• Key contributor to setting up and qualifying a global supply chain of preferred integration partners to accelerate new product development from concept to prototyping to production
• Led the identification and purchasing of critical CapEx equipment needed to scale operations from a manual benchtop process to a semi-automated operation, massively increasing capabilities and capacity
• Led the R&D to identify a solution for surviving environmental stability testing, including 1,000 hr. @ 85°C/85%RH for automotive

Canton, Massachusetts, United States

• Built a small but highly capable Team of Engineers and Technicians
• Led the Floorplan Design and Buildout of the Manufacturing Operations and Quality Control facility
• Lead Technical Support to the Business Development Team, conducting technical calls for qualified leads and generating technical documents such as TDSs, CoAs, SDSs, App. Guides & Brochures
• Key contributor to improving our processes and documentation, ultimately received ISO9001:2015 Certification
• Built partnerships and relationships with customers to define their specifications, steering them to the right product in our product portfolio, and worked with the Engineers to go from concept to functioning prototype.
• Developed Player/Coach skills, by balancing responsibilities as both Lead Engineer and Team Leader

Canton, Massachusetts, United States

• Started the Applications Engineering Team after CHASM acquired the assets of Southwest Nanotechnologies and became CHASM Advanced Materials in 2015
• Developed a low solid, screen-printable, 100% transparent, 0% haze, CNT ink formulation used for acting as a functional etch mask for low-cost patterning of transparent conductive films
• Conceived and developed a CNT / AgNW Hybrid Transparent Conductive Film, resulting in a synergistic effect between the two, ultimately received multiple patents
• Conceived and developed a CNT / Metal Mesh Hybrid Transparent Conductive Film, to achieve <0.2 @ >85% Visible Light Transmission for transparent antennas

Canton, Massachusetts, United States

• Designed and built equipment to support a modular roll-to-roll slot-die coating machine used to coat CNT aqueous inks
• Worked as part of a Team to develop a novel screen-printable CNT ink which did not require rinsing out surfactants post-drying
• Designed and built enclosures, to reduce the dB of sonication machines used during the dispersion process, which was irritable to hear

Canton, Massachusetts, United States

• Developed benchtop chemistry skills, handling hazardous powders and solvents to produce novel CNT inks
• Gained exposure to nano materials with a focus on carbon nanotubes, how to handle them safely, disperse them into aqueous inks, and how to coat them using various methods including slod dye, rod coating and spray.

• Conducted lab experiments on various nano materials used in coatings and composites.
