Si Amar Dahoumane, Ph.D.


Dr. Si Amar Dahoumane earned his Ph.D. from Paris-Diderot Univ. (France, 2010) on implementing the feasibility of gold colloid biosynthesis using living cultures of several species of microalgae. Besides, he studied the toxic effects of lab-made nanoparticles on the same photosynthetic organisms. During his M.Sc., Si Amar achieved the electroless functionalization of nanodiamonds via the combining of diazonium and polymer chemistry.
As a post-doctoral researcher at McMaster Univ. (Canada), Si Amar worked on the design of high-density living biohybrid micro-arrays and on the scalable production of portable, shelf-storable 96-well plate assays, each of which made of bacteria immobilized within silica-derived materials. He also demonstrated the ability of living microalgae to stoichiochemically control the composition of cell-made bimetallic alloy colloids.
Currently, Si Amar shares research projects with Dr. Clayton Jeffryes (Lamar Univ., USA) and with Dr. Mourad Mechouet (Mouloud Mammeri Univ., Algeria).
