Professional Experience_________________________________________________________
Mechanical Engineering Intern
TCI – Germantown, WI
January 2014-January 2015
• Conducted theoretical analysis and thermal testing on heat sink mounted electrical components to compare the efficiency of various thermal greases and fan configurations. Applied heat transfer laws to gain initial results. Validated results using laboratory equipment and a product prototype.
• Performed airflow testing on enclosures to assure fans were operating optimally. Obtained pressure differential data using a manometer. Calculated CFM using air speed measurements taken with an anemometer.
• Redesigned a UL type 1 enclosure to reduce the cost of a product line. Eliminated unnecessary bends and welds in individual sheet metal parts while maintaining the fit and function of the overall assembly.
• Created and updated CAD files and BOMs for manufacturing and customer use. Made drawings and 3D models of custom products for rushed purchase orders.
Undergraduate Researcher
University of Wisconsin Milwaukee – Milwaukee, WI
May-August 2013
• Worked on an interdisciplinary team that researched thermal acoustic tomography as an alternative cancer imaging technique.
• Edited LabVIEW codes that performed scans on biological specimens. Integrated multiple pieces of hardware into the scanning protocol, including a signal generator, ultrasound system, oscilloscope, stepper motor, and data acquisition system.
• Designed and constructed a waterproofing systems to safeguard electrical devices from potential test bed leaks. Devised and implemented various other mechanical components to facilitate testing.
Academic Projects______________________________________________________________
Supersonic Flow Testing Device – Senior Design Spring 2015
• Designed a supersonic flow-testing device to be implemented into an undergraduate fluid mechanics laboratory. Studied the characteristics of supersonic flow. Researched previous work done by companies and universities to learn from their successes and failures.
• Preformed multivariable initial calculations, CFD, and testing to determine if current equipment could be used to produce supersonic flow.
• Designed a converging-diverging nozzle that could produce intermittent supersonic flow, permit observation of a test geometry interacting with supersonic flow, and facilitate shadowgraphy of shock diamonds.
• Authored a laboratory manual to give undergraduat...
