Mike Mfarej assists the firm’s Biotechnology Practice. The technology areas in which Mike has the most intellectual property experience include gene expression modulators (e.g., antisense oligonucleotides such as siRNA, gapmers, exon-skippers, etc.), genome engineering (e.g., CRISPR/Cas, prime editing, base editing, etc.), applications of aptamers and chemically modified oligonucleotides, recombinant viral genome-based therapies (e.g., rAAVs), cell-based cancer therapies, antibody-drug conjugates, microorganism engineering, molecular biology approaches for agriculture and food production, molecular and biomolecular diagnostics, and treatments for neurological, neurodegenerative, and neuromuscular disorders. 

Prior to joining Wolf Greenfield, Mike earned his PhD from Lehigh University’s Department of Biological Sciences. His research focused on investigating cellular pathways that link the redox stress response to regulation of cellular reproduction, as well as studying the roles of DNA damage and intercellular communication in rare diseases. During his doctoral work, Mike gained experience in genome engineering/gene editing, protein engineering, gene expression analyses, and cell-based assays in addition to developing expertise in the areas of chemical biology, developmental disorders, enzymology, genome integrity, cell cycle biology, and intercellular communication.
