# Hussein Naim

Hussein Naim is a Lebanese-Swiss biochemist and molecular virologist, known for his research in cell biology (membrane protein sorting and internalization) and virology (measles, SARS, HIV and Influenza). He has held several leading positions at prominent universities and biotechnology centers.

## Scientific career

Hussein Naim received his Ph.D. degree in biochemistry from the University of Bern, Switzerland in 1989. After being appointed at the University of Texas Southwestern Medical Center at Dallas, his research focused on the (i) basis of enveloped viruses assembly, and (ii) the mechanisms of membrane protein sorting and endocytosis in polarized epithelial cells. His research was instrumental towards understanding the intracellular mechanisms of viral and membrane protein sorting in epithelial cells and the cell-surface assembly of several RNA viruses. He was appointed as a faculty member at the institute of molecular biology of the University of Zurich. His research focused on the development of novel viral vectors and therapeutic molecules that paved the way towards translational research (live recombinant vaccines and cancer virotherapy). Later, he became the director of vaccine research at Berna Biotech (now Crucell).
