Making new things that fly

Aliso Viejo, California, United States

I provided engineering services on the design (Solidoworks) and manufacturing (injection molding and SLA 3D Printing) of a novel medical device, its packaging, and the system's assembly. I coordinated with the pharma and engineering teams as well as outside stake holders to identify pathways and opportunities in the design process. I utilized an in-house SLA 3D printer to rapidly prototype, test, and iterate on those design decisions pushing the program forward in pursuit of aggressive review and delivery dates.

Las Vegas, Nevada Area

Worked with a small team of engineers to develop the B330 expandable space habitat. Main project involved working with our launch provider to design the hardware for the B330/launch vehicle interfaces and support structures.

Pasadena, California

Conducted research for the Mars Sample Return project. The task objective is to implement a method of “Simultaneous Separation, Seaming, Sealing, and Sterilization using Brazing (S4B)” as a means of assuring a sample is returned to Earth in a sealed container sterilized from potential biological contaminants. My responsibilities included;• Designing and machining test cylinders for the iterative brazing development process. • Using a lathe, machined stock sized stainless steel tubes into the test configurations• Performed brazing process, seeking uniform melting and effective surface wettingThe testing process became very iterative, making small changes to the test parameters or cylinder design configurations after incorporating the lessons learned from the previous experiment. During initial tests, using torches and a convection oven, oxidation would severely harm the brazing process. A bell jar vacuum chamber was set up with an induction heater to run the tests. Argon back fill was utilized to further minimize oxidation during vacuum testing. Our completion of proof of concept experiments in the bell jar vacuum will pave the way for the final tests involving a simulated Mars atmosphere
