PROFILE

Senior mechanical engineering student with previous cost engineering experience at Oshkosh Corporation’s Defense Branch. Graduating from Undergrad in May 2021, attending the University of Chicago’s MA program in Economics

(MAPSS) in the Fall. Interested in full time internship positions for the summer of 2021. Particularly interested in positions that utilized statistical analysis, GD&T, and applied machine learning in their work. EDUCATION

Michigan Technological University - Houghton, MI

BS Mechanical Engineering, Minors in Economics and Mathematics - May 2021 (Expected) GPA: 3.82/4.0 Major GPA: 3.75

WORK EXPERIENCE

Blue Marble Security – Deringer Ney Houghton, MI Senior Capstone Project Manager Sept. 2019–Dec. 2020 o Designed, Manufactured, Assembled, and tested a state-of-the-art test bed prototype for slip rings — simultaneously testing brush force, runout, and electrical resistivity over two-week long periods of continuous high-speed rotation. o Applied GD&T design engineering standards to drawings for rapid prototyping. o Developed Project Budget in Excel with an accompanying project schedule in Microsoft Project. Oshkosh Corporation - Oshkosh, WI

Defense Cost Management Engineering Co-op May–December 2018 o Developed cost estimates using the software Costimator for over 250 different parts, using manufacturing data on processes such as injection molding, fiber laser cutting, CNC machining, brake pressing, tube forming, and more to identify $3.5 Mil in cost savings opportunities.

o Recommended $40,000 in cost optimization design changes informed by cost models to the engineering department. o Assisted with over one dozen supplier pricing negotiations through in-depth cost analysis detailing what the supplier’s cost-plus pricing should be using our cost estimates. Corporate Cost Management Engineering Intern June–August 2020 o Developed cost modeling tools for Costimator utilizing laser cutting data. o Classified over 200 wire harnesses utilizing taxonomy codes and collected data for regression-based cost estimates. o Updated the cost analysis request tracking spreadsheet to utilize updated data.
