  I am currently the project manager of the water recovery system (WRS) PPP Team. The UPA was installed on ISS in 2008 to recover potable water from the pretreated urine which would effectively reduce the mass of water required to resupply the International Space Station (ISS). As the PM of the UPA PPP Team, my responsibilities include managing and overseeing the development of the alternate pretreatment which includes working with key stakeholders like Marshall Space Flight Center, Space and Life Sciences, Safety, Mission Operations, the ISS Program, and Russia. I also directly oversaw the development and certification of the ion exchange (IX) bed team and manage and run the schedule and budget for the entire project including advising program on the contract and proposals obtained from Russia. Show less As the ICWC hardware manager. The ICWCs are needed to store water for the United States Orbital Segment (USOS) systems onboard ISS. As the hardware manager of the ICWCs, my responsibilities include managing a contractor team in failure investigations and mission support and supporting any requests for hardware from ESA, other NASA centers, JAXA, and the ISS program. Recently I oversaw the safe return of two of three filled ICWCs on-board Dragon (SpaceX 1). The water in these bags is currently being used to extend the life of the water aboard ISS. In 2012, I also successfully delivered over 75 flight ICWCs and 210 flight stabilization frames to program. 24 ICWCs have been delivered to JAXA in support of the upcoming HTV-4 Launch and 50 stabilization frames have been delivered in support of the ATV-4 launch. The stabilization frames were built to mitigate the risk of the ICWCs leaking on-orbit. Uniquely, the frames were built using an injection molding process. This process allowed us to build a large number of frames with a high repeatability, consistent quality, quick turnaround time, and low overall cost. Show less As the hardware manager of the APLSS and EMU Gas Sensor, I worked with a Small Business Initiative Research (SBIR) company to initiate the development of a gas sensor in the next generation advanced spacesuit. The new gas sensor was required to measure the concentration of carbon dioxide, water vapor, and oxygen in the ventilation loop. I also investigated whether or not the technology in the gas sensor can replace the gas sensor currently used in the EMU. While working this project I gained experience with starting with low test readiness level technology and developing it into something that can be used in flight. Show less The LSU falls under the CxP Vehicle Interface Element (VIE). The LSU provided closed loop breathing air and cooling, power, data, communications, and a restraint tether. As the LSU SSM, I managed and oversaw the development of hardware requirements and design, the execution of integrated crew and engineering evaluations, manufacturing, assembly, and verification testing of the LSU subsystem. This project introduced me to the world of life support systems since the LSU served as the connection point between the space suit and the vehicle Environmental Control and Life Support System (ECLSS). We built three generations of hardware prior to the Program cancellation. Show less As the HST EVA tools and equipment manager, I was responsible for processing over fifty-five (55) units of space hardware and the final delivery of twenty-nine (29) units of hardware for flight aboard STS-125. I was also responsible for managing the project budget and a contractor team. One of the tools in this tool set was called the Manipulator Foot Restraint (MFR). The MFR provides a crewmember with a foot restraint platform, tool storage location, and the ability to position his/her body and hardware as required for various EVA tasks. This tool attaches to the Remote Manipulator System (RMS) with a crewmember secured to the boot plate. While working on this project, I gained experience with working on a failure investigation team as well as interfacing with a team that expanded to two other space flight centers (Goddard in Maryland and Kennedy in Florida) and a Canadian-based company specializing in key interfaces of the ISS robotic arm.
