Materials Science and Mechanical Engineering​ is a field within the Engineering Sciences area of study at the Harvard John A. Paulson School of Engineering and Applied Sciences. Prospective students apply through GSAS; in the online application, select  “Engineering and Applied Sciences” as your program choice and select "PhD Engineering Sciences: Materials Science and Mechanical Engineering​" in the Area of Study menu.

Mechanical engineering research ranges from fundamental work in solid and fluid mechanics to diverse studies in materials, mechanical systems, and biomechanics. Characterizing the performance of such systems often depends on understanding behavior at several scales, requiring, for example, the mechanics of dislocations and other imperfections, grain boundaries, interfaces, and material heterogeneity.
