• Designed a test board with duplicate channels and SMP connectors for de-embedding the losses of SAS 12G and PCIe 8G interfaces and allow for analog characterization of serdes drivers in a custom ASIC. Created S-parameter models of the full channel using Ansoft HFSS.• Performed signal integrity simulations and devised routing rules for all major interfaces used to implement a QSeven SOM board in a medical product.• Served as the lead engineer in an obsolescence redesign for several PCBs used in a commercial aircraft system. Took the development from schematic capture all the way through fabrication and assembly. Managed design and manufacturing resources across multiple sites including those in Malaysia and Scotland.• Executed verification protocols to test high level functions and circuit level performance against design requirements for a CPR assist device. Revised protocols for errors, measurement techniques and process inefficiencies.

• Developed a high speed circuit simulation method using SPICE, MATLAB, and 3D EM field solvers. Applied RF concepts of transmission lines and s-parameter modeling in analysis. Studied the effects of trace geometry, board material, via stubs and equalization to optimize link designs in PCBs and IC packages.• Generated test plans for FBD and SAS/SATA interfaces based on industry specs. Measured signal waveforms and eye diagrams using digital scopes and compared against simulations. Set proper firmware settings and ran software tests to stress hardware performance. • Analyzed power decoupling schemes of PCBs and IC packages to minimize impedance resonances and switching noise using Speed2000. Correlated simulated impedance profiles with VNA measured S-parameter data. Led presentations and web seminars to demonstrate how to investigate power integrity issues using the Speed2000 tool. • Uncovered the root cause of a failing 800MHz bidirectional data bus implemented in a server product line. Revised an outdated analysis to account for incomplete modeling and led daily meetings to discuss results. Defined new design requirements for all PCB, flex and cable components resulting in full restoration of the link’s functionality.• Jumped into a verification role for an understaffed ASIC team and learned to use Synopsys IC tools and TSMC CMOS libraries in under 1 month without prior experience. Devised an analysis process to ensure electromigration and IR drop compliance for a power grid design of a 19.4mm ASIC in 90nm CMOS• Collaborated with Synopsys consultants and ASIC designers to ensure electromigration and IR drop compliance for a power grid design of a 19.4mm ASIC in 90nm CMOS. Learned to use Synopsys IC tools and TSMC CMOS libraries in under 1 month without prior experience. Met an aggressive deadline by coding efficient scripts for simulations and data collection, creating software bug workarounds and training 2 colleagues to assist the verification effort.

• Conducted research experiments involving Insulin-like Growth Factors on tumor growth.• Maintained cell cultures and performed molecular biology techniques such as gel electrophoresis, PCR, Northern/Western/Southern blots. • Published in Clinical Cancer Research Nov 1998 “Inhibition of Tumor Growth by a Dominant negative Mutant of the Insulin-like Factor I Receptor with a Bystander Effect”.
