Dr. Fares is a Professor of Molecular and Cellular Biology and a member of the University of Arizona Cancer Center.  The goal of his studies is to decipher a novel cell biological pathway linking regulators of endosomal and lysosomal transport; this will advance the field of membrane transport, identify the basis for tissue-specific death in some diseases, and identify potential therapies for the lysosomal storage disorder Mucolipidosis type IV. 

Dr. Fares established the C. elegans model of this disease ten years ago and his group has made significant contributions in using it to elucidate functions of the Mucolipidosis type IV protein (TRPML1/mucolipin-1 in mammals and CUP-5 in C. elegans) and to understand the basis of the Mucolipidosis type IV lysosomal dysfunction and tissue degeneration. 

Furthermore, he has significant experience in genetic and cell biological analyses of membrane trafficking in C. elegans.  In summary, he has a demonstrated record of productive research projects in Mucolipidosis type IV and membrane trafficking.
