Ms Wilkerson,

Currently, I am working at the engineering physics and engineering materials department at École
Polytechnique de Montréal. I wish to submit my application for Research Engineer - Thermoelectrics and Related Sc.

I have a very good knowledge of the science of materials, in particular in metals, semiconductors (thermoelectric alloys) and dielectric materials (ceramics and polymers). I also have a very good knowledge on images analysis, design new materials, materials processes, planning and project management.

My various work experience in industry and academia have enabled me to develop my skills to work with
groups and to manage my time. I feel that my background and my sense of the responsibilities would
enable me make a contribution at RTI.

I am looking forward to meet you in interview and to transmit all other information that you may request

Sincerely yours

Abdelkhalek SAMI
