Christopher Yurgel

• Studied at the Aerodynamic Institute of Aachen to investigate buffer conditions at various Mach numbers and angles of attack over an airfoil. Supported PhD students with various tasks such as wind tunnel operation, and high speed PIV camera setup and operation. • Post-processed data from wind tunnel testing using various techniques in MATLAB to find buffet frequency and eliminate background image noise using singular value decomposition techniques.

• Supported NASA Student Launch (SL) Team and NASA Human Exploration Rover Challenge (HERC) Team by reviewing technical documentation and engaging with students across the country while conducting design review video conferences.

• Worked with engineers in the electro-mechanical systems branch at Goddard Space Flight Center to create design tools for a modular robotic arm purposed for space applications. • Utilized MATLAB, SolidWorks, and Simulink to create programs to calculate forward and reverse kinematics, inverse dynamics, torque control via proportional-integral controller, and an exploratory script to automatically calculate the Denavit-Hartenberg parameters based on robot arm geometry.

• Worked with fluid dynamic engineers to research and develop the propellant transfer subsystem on the spacecraft for the OSAM-1 mission. • Developed a method to convert piezoelectric pressure transducer readings to an absolute pressure scale. • Conducted leak testing to further understand the characteristics of propellant leaks through small diameter orifices while in low Earth orbit.

• Administered primary medical care for patients on scene and en route to hospital. • Ensured safe and effcient operation of emergency vehicle and overseen crew duties. • Communicated effectively with patients despite cultural differences, high stress situations, medical conditions, and legal concerns. • Worked closed with dispatchers, other medical personnel, and law enforcement to ensure the highest level of care possible.

• Coordinated with case managers, parents, foster parents, and children involved in Child Protective Services (CPS) cases to arrange and oversee visitations. • Provided safe and timely transportation to and from visitations for children involved.

• Provided medical care to patients experiences withdrawal symptoms from substance abuse. • Assisted in daily living activities for those in rehabilitation from addiction.

• Greeted customers at door, collected and returned shopping carts, and quickly and efficiently bagged customer's groceries.
