Why Dal?

Dal has excellent professors, great interaction between supervisors and students, as well as a friendly and helpful community, especially for an international student.

What inspires me

The purpose of my research is the characterization of potential thermoelectric materials. Thermoelectric materials are interesting for renewable energy and sustainability because they harvest heat and convert it to useful energy. However, thermoelectric materials are still not applied in many commercial products due to low efficiency. To achieve enhanced efficiency, a better understanding of thermal conductivity is very important. Therefore, I focus on the synthesis and characterization of the thermal conductivity in a broad range of materials, such as clathrates, layered structures, and nanomaterials.
