  • Matthew recently received a patent – Marengo, M.S., and Garcia-Blanco, M.A., inventors; Duke University, assignee. (2016). Synthetic regulation of gene expression. US patent 9,284,575.
  • Matthew Marengo previously worked at GrassRoots Biotechnology: GrassRoots’ mission is to employ cutting-edge expertise in agricultural biotechnology to create better biofuel, food and industrial crops. GrassRoots is an agricultural biotechnology company that utilizes a Systems Biology approach to develop novel and valuable crop lines for the biofuel, food and industrial markets. The company, formed in 2007, intends to commercialize innovations and expertise developed by Dr. Philip Benfey at Duke University. Dr. Benfey is one of the world leaders in the fields of genomics and development. His research in the areas of plant genomics and plant root development form the core of our technologies, which will provide a competitive advantage in bringing new products to the agricultural markets.
  • Formerly:Research Fellow at Duke University Medical Center from September 2008 – December 2011 (3 years 4 months) Matt studied how signaling pathways in the tumor microenvironment regulate gene expression at the level of alternative splicing.
  • Fellowships:
    • Campus wide: 1 year of T32 Molecular Cancer Training Grant funding.
    • National: 2 years of NRSA (limited to 2 because of T32 above).
