• Design innovation - redesigned the Dilator to improve manufacturability - Yield improved from 10% to 95% - Cost reduced from $150/unit to $15/unit - Improve performance, enhanced echogenicity• Design For Manufacturability (DFM) - Invented Cable-Lock mechanism to quickly attach cables to spool - original design, eliminate the swaging process. Allowing nine other DFM elements to piggy-back. - Reduced cycle-time from 183 minutes to 36 minutes (80% time saving) - Introduced 13 new parts, 10 new processes and 14 pieces of equipment - Eliminated 12-hour cure time, Hysol epoxy - Eliminated the need to perform torque check and the use for a force gauge to set cable tension - Eliminated ergonomic issues with using small setscrews and pressing solid pins - Build-in rework capability - Easily scalable to meet rising production output• Project Manager - met all major milestones and allowed Evalve to be sold to Abbott Vascular in a timely manner.• Design optimization – redesigned the Bullet Nose to increase cable strength by 200%. Implemented new design into production under 60 days. This allowed the company to restart production with minimal financial impact.• Design Human Factor - redesigned the CDS Handle to have a One-Way Actuator to prevent human induced error.• Process Innovation - Introduced the use of a plasma surface treater to enhance bond strength on the CDS Hemostasis Valve and the Clip Introducer. Developed two-ply cable braiding process with precision starting and stopping point. • Process Improvement - Introduced the use of LED light sources for curing adhesives. Faster cycle-time and improve reliable. Opens the door to modern adhesives and the elimination of epoxy.• Just finished Guide Cable-Lock DFM Project to reduce cycle-time from 172 minutes to 64 minutes (63% time saving). Designed and qualified 19 new parts, 10 new processes and 29 pieces of equipment. • Set-up pilot line.

• Developed new catheter laser drilling process. • Worked with laser integrator to design & build an automated laser drilling machine with adaptive vision system. Machine is capable of acquiring new targets based on moving landmarks. Post-laser drill, machine makes quality decisions.• Designed new catheter tip coating equipment, using new and break-thru process, that allows hydrophilic solution to penetrate deep into small openings. This allows simultaneous coating of inside & outside surface of tip.• Developed new, ultra-fast, UV curing equipment; using microwave powered lamp - up to 10X faster than conventional light. Proprietary chamber coating allows for even distribution of light, one light source cures all surfaces of part - 360 degree curing.• Worked with vendor to develop an automated inspection machine to evaluate catheter tips. Machine can inspect any stent-like structure for defects.• Supervised 2 SolidWorks designers and 2 technicians; mentor interns and junior engineers.

•Principal Investigator - Determine root cause and implement containment and corrective actions.•Resolved a complex reliability issue on the US Navy F-18 Head-Up Display (HUD).Background: After a production run of twenty years newly produced HUD experienced unacceptable level of failures.Problem: Primary failure mode was over-voltaged video amp transistors resulting in HUD shutdown. Failures occurred at many stages of production: component, PCB, Tin Box, integration, on test bench, in the HALT chamber, on the aircraft and during actual combat missions.Actions: Principal Investigator - Led a cross-functional team to investigate failures. Identified and rectified discrepancy at the following steps: transistor specs requirements, supplier screening procedure, in-house production and testing methods, and on-wing operating conditions.Result: No HUD failed during production or on-wing during the past twelve months. Corrective actions were 100% effective.

•Supervised 6 Engineers and two technicians.•Project Management: Complete ownership of project from start to finish. Performed cost/benefit analysis, requested funding and purchased parts; provided engineering modification instructions and mechanic/inspector training.•Developed short/long-term projects to maintain, overhaul and repair engines.•Provided real-time technical support for all engine sub-systems, i.e. mechanical, electrical, hydro-mechanical, pneumatic, computer software and aircraft nacelle structures (metal and composite material repairs).•Conducted failure investigations of all premature component removals. Performed failure analysis of incident/accident related to failed components to determine root cause. Proposed immediate and long-term fix.•Developed in-house repair to reduce engine operating cost.
