Dr. Jacobs' current and near-term research interests combine mechanical testing with in situ, high-resolution electron microscopy techniques to make fundamental contributions in three thrust areas:

(1) investigating the mechanics of interfacial contact in emerging nanoscale applications, including understanding the connections between contact mechanics and functional properties, such as electrical contact resistance;

(2) exploring deformation and failure in nanoscale materials for extreme environments, such as those in next-generation energy applications; and

(3) interrogating differences in mechanical properties between crystalline and disordered systems, with the particular focus on disentangling differences due to structure from those due to chemistry.
