* MS by Research (or MS by Thesis): This degree emphasizes original research and culminates in a substantial thesis demonstrating a significant contribution to the field. It's geared towards students intending to pursue a PhD or a research-oriented career. The coursework component is usually less extensive than in an ME degree.
* ME (Master of Engineering): This degree is typically more focused on professional practice and application of engineering principles. It often involves a significant amount of coursework, potentially including projects, but usually doesn't require a large-scale research thesis. It's geared towards students looking to enhance their professional skills and advance their careers in industry.
In short, an MS by Research is a research-focused degree, while an ME is a more professionally oriented degree. The value and recognition of each depend on the specific institution, the field of engineering, and the employer. While both are Master's degrees, they cater to different career paths.
