San Jose

• Took complete ownership of an upcoming medical device in the Stryker pipeline, from defining requirements and user interaction modes to the redesign and development of both hardware and software for the device, shrinking the device by 50% while making it twice as complex.• Co-authored a protocol stack for the future of device to device communication between all Stryker devices and implemented a compilable template project in C to encourage adoption and insure compatibility.• Designed, implemented, and tested code for sensor drivers written to high reliability MIRSA standards.• Worked with cross functional team to support two prototype builds at PCB manufacturing plants in Malaysia.• Submitted a patent for multi-device broadcast communication and localization within an operating room.• Attended over 30 hours of surgery case visits.

Durham, Nc

• Developed and simulated a model network of neurons using MATLAB which was used to perform computer image processing.• Built a MATLAB program to simulate self-learning artificial neuron networks for detecting stimulus patterns.• Planned and taught a computational methods course in neuroscience engineering.

Durham, Nc

• Designed in Solidworks and built a detachable EEG lead which extended continuous recording of hibernating lemurs for up to 5 days.• Machined hibernation chambers to house infrared cameras, EEG wires, and a hypoxic chamber allowing doctors to conduct controlled EEG studies on lemurs with clear visual feedback.• Engineered camera electronics to allow for simultaneous infrared video recording in order to monitor lemur movement without disrupting hibernation.

San Francisco, Ca

• Constructed a MATLAB toolbox to automate EEG and ECoG analysis in implanted rats.• Designed a computer monitored rat maze to dynamically conduct rat training in both a lever pressing task and a reaching task that decreased human work and standardized training.• Fabricated linear microdrives for post-operation repositionable ECoG leads to be mounted onto the surface of the rat skull which allowed for micrometer accuracy in electrode placement.

Berkeley, Ca

• Programmed and simulated differential and stochastic models of PCR assays in MATLAB to predict assay feasibility before lab testing.• Created a MATLAB user interface to automate image detection and analysis of circular DNA encapsulated beads.

Los Angeles, Ca

• Planned and taught electronics labs to demonstrate soldering techniques and the prototyping and debugging of simple circuits.• Assisted the lead professor in teaching high school students in electrical engineering topics.• Devised new problem sets to challenge and encourage student learning and cooperation.
