Experience

Senior Mechanical Engineer

Aug 2018 - Feb 2019 (6 months)

Designed (SolidWorks) and machined (CNC/Lathe/Mill) replacements and upgrade parts for the nanoProber machine. The nanoProber uses a Scanning Electron Microscope (SEM) to image individual bit-cells on a delayered chip and then use eight nano-scale electrical contacts to perform various operations on the bit-cell to ensure proper operation of the transistors.

Flight Controls Software Engineer

Sep 2017 - Aug 2018 (11 months)

- Designed (CATIA v5) a Variable Reluctance sensor-based device for measuring RPM, Torque, and Azimuth for masts within Helicopters and Tilt-rotors (Patent Pending). - Developed a nested controller (Simulink /Embedded C) for the pylon conversion down-stop engagement system of the v247 Unmanned Aircraft - Developed an innovative algorithm for state estimation and control of the tail wheel steering on the v280 aircraft and tested using Software in the Loop methods

Founder and Chief Engineer

Sep 2014

- Designed, built, and tested the world’s only quad-turbine vertical lift drone - Researched and developed innovative electromechanical thrust vectoring systems - Performed CFD and FEM analysis on airframe and turbine-nozzle system - Developed embedded controllers for the drone using C/C++ in a Linux environment - Installed and configured sensors: IMU/Magnetometer/GPS/Cameras/Lidar - Patented innovative control systems and propulsion methods

Research Assisstant

Jul 2014 - Aug 2015 (1 year)

- Designed and manufactured a small Kerosene/Hydrogen Peroxide liquid rocket-engine - Developed reaction control systems (Matlab/Simulink) for interplanetary drones - Proposed a cubesat mission for NASA/JPL to study the asteroid Apophis

Engineer II (contractor)

Jan 2014 - Jul 2014 (6 months)

- Designed a test-rig for the next-generation F100 Jet-Engine (Unigraphix NX) - Performed structural analysis on engine mounting fixtures (ANSYS/HyperMesh)

Engineer II (contractor)

Jan 2008 - Aug 2013 (5 years)

- Analyzed structural integrity of components of a Nuclear Reactor (ANSYS/HyperMesh) - Implemented advanced FEM techniques – Harmonics/non-linearity/transients - Performed Fourier and Power Spectrum Density analysis on sensor data (Matlab). - Developed APDL code to solve FEM models automatically on a Linux-based server

Engineer I (contractor)

Sep 2007 - Dec 2007 (3 months)

- Analyzed structural integrity (ANSYS) of tools used to test the RD-180 Rocket Engine

Education

Master of Science

2008 - 2010 (2 years)

Publications

Flying, Hopping, Pit-Bots for Cave and Lava Tube Exploration on the Moon and Mars

Wheeled ground robots are limited from exploring extreme environments such as caves, lava tubes and skylights. This study proposes a rocket-powered robot, the size of a small drone to explore these destinations.
