CREO Thermal Model

 My first thermal model in CREO.

B. SolidWorks

Block with Hole SolidWorks

My first toy project in SolidWorks, a block with a hole. (I hope to have a picture of a 3D printout and a home CNC'ed part made from it posted here in a few days.)

I am matriculated in a BSE program in Mechanical Engineering at UWM.

I have a full-time co-op for Fall 2023 - Summer 2024 at Copland Corporation (formerly a division of Emerson) working in Data Science.

I have a part-time internship for Fall 2024 at Copland Corporation (formerly a division of Emerson) working in Data Science.

Research Interests: My Ph.D. is in manifold topology under Prof. Craig Guilbault (UWM's Math Department's Chairman). However, I am moving my research interests into an application of manifold topology, specifically robotics engineering. I have a blog related to my learning experiences in these new areas of STEM (for me), This Week's Finds in Second-Order Ordinary Differential Equations on Manifolds and Geometric Control Theory.
