ABOUT ME

I am a recent University of Iowa graduate with a bachelor’s degree in mechanical engineering and a minor in mathematics. I have built a strong background in 3D-modeling and design of mechanical systems through exposure to Creo Parametric and finite element analysis software from both personal design projects and class assignments which I hope to use in my career. During my time at the university, I worked as an IT technician for the ITS Help Desk, troubleshooting and solving software problems for students and faculty members which gave me invaluable experience in customer support and communication as well as computer troubleshooting.

​

​

I have developed a great interest in complex geometries and how they can be utilized in the design of clever, efficient, stable mechanical systems to produce a superior or unique product. Interacting with these geometries, including involute, trochoid, and cycloid curves in gears, among other things, has become a passion of mine and has driven me to seek out new and exciting shapes, curves and underlying math relationships to fuel my designs.

​

The most ambitious and rewarding projects that I have worked on thus far include my Nixie-Tube clock, lathe design project and gear modeling project, which have each greatly improved my skill in relevant categories like 3D-modeling, circuit design, data analysis and prototyping of mechanical systems. Using modeling software, coding methods, new manufacturing techniques and experience with circuits in tandem with copious amounts of internet research, I constructed a decorative clock which displays time on cold cathode tubes. Similarly, I modeled my own lathe machine from scratch in Creo Parametric based on existing lathe technologies and have had to learn about many new precision machining techniques and tools in order to properly manufacture the lathe in my free time. While the lathe has required the largest time investment, I have learned more from my gear modeling project about the fundamental geometries driving perfect gear interaction and extreme gearbox requirements. I began each project without a mastery of all of the skills needed to finish it. Through execution of these hobby projects, I have been able to solidify and build upon my education, sticking with them to the end and finishing with new skills in my hypothetical toolbox.

I am currently seeking a mechanical engineering design position in which I can exercise my skills in modeling, machining, analysis and optimization. I enjoy the challenges that come with a new design project and am eager to learn more about design standards and techniques, improving efficiency, and manufacturing techniques to further improve my performance and experience. I would love to hear of any available opportunities that could fit well with the type of work expressed here, and I can be reached at davidjacullen@gmail.com or through the contact section!
