Joshua B. Hecht has over 5 years of experience in aerospace engineering. He has worked as an Aerospace Engineer III at Paragon Space Development Corporation where he managed production of a humidity control subsystem and led testing and failure analysis. As a graduate research assistant, he developed computer models and a thesis evaluating a self-regulating freezable heat exchanger. Prior to this, he worked as a Satellite Command Controller at the Laboratory for Atmospheric and Space Physics, conducting commanding for five NASA spacecraft.
I am Ph.D. student at Wright State University. My research area is computational mechanics and design optimization. I mainly focused on design optimization for coupled fluid-solid interaction problems with applications to aerospace vehicles.

Open Source Work-flow for Surface Interpolation with Curvilinear AnisotropyMichele Tobias
GitHub repository for the project: https://github.com/MicheleTobias/CurvilinearAnisotropy
Traditional approaches to interpolating a surface from point samples often assume that if anisotropy is present in the data, it is along a straight line. However, this assumption breaks down for many data-sets, such as river bathymetry, elevations near coastlines, or levels of pollutants along roads. I will present a work-flow using open source tools to make use of the curvilinear anisotropy present in many data-sets by transforming the curved data-set into a straight line (QGIS and PostGIS), applying an interpolation to the transformed data (with R... or use SAGA, GRASS, or other program with interpolation tools), and finally re-bending the interpolated surface back to the data's original shape (PostGIS).

EXPERIENCE
Aerospace Engineer III October 2013 – Present
Paragon Space Development Corporation Tucson, AZ
• Program manager for the production of Humidity Control Subassembly (HCS) flight units. The HCS is
spaceflight ECLS hardware used within the air revitalization system onboard the Boeing CST-100 Starliner.
• Wrote all test plans and procedures for qualification and acceptance testing. Conducted leak, performance,
vibration and proof testing at both the Paragon facility and outside testing labs. Compiled all data and wrote the
majority of test reports. Created ADPs that were accepted by Boeing when each unit was delivered to KSC.
• Successfully led a team of engineers to determine the root cause and corrective action of a leak failure on the
last HCS flight unit. Used three months of testing, reporting and data analysis to present the results to the
customer. This allowed Boeing to make the determination that the issue was a manufacturing failure, rather than
a design/fleet failure, allowing the Paragon HCS units to be integrated onto the spacecraft, and not scrapped.
• Conducted engineering development, recovery, and balloon fill operations during the record breaking flights of
the StratEx program in Roswell, NM. Hands-on repair and development of essential components used to
facilitate the successful launch of the pilot. Primary representative of operational infrastructure and logistics
Graduate Research Assistant / Project Engineer on SRFHX January 2012 – December 2012
University of Colorado Boulder, CO
The SRFHX is a lightweight and freeze tolerant water/ice heat exchanger used to passively regulate s/c heat loads
• Created and verified theoretical computer models of spacecraft LEO heat flux, thermal control system trends,
SRFHX heat rejection performance, and equivalent system mass
