Remi Longtin Ph.D., is a scientist and consultant with international experience in R&D and project management. His technical expertise is on the synthesis, characterization, processing and technological application of nanomaterials. As the managing director of AspectNano services at DLA inc., Dr. Longtin  applies his knowledge of nanomaterials to help organizations understand and manage the health, safety and environmental risks posed by  nanomaterials (NanoEHS).  Worker safety and environmental protection impact directly the bottom line. Integrating the nano EHS aspects of nanomaterials in existing management systems reduces cost and maintain a positive corporate image.
