Dr. Mancini received his B.S. in Polymer Chemistry from the University of Pittsburgh. He received his Ph.D. in Organic Chemistry from The University of California, Los Angeles while working as an IGERT fellow through the California Nanosystems Institute. He was a postdoctoral researcher at the University of California, Irvine prior to joining the Washington State University faculty in 2015.
The Mancini research group uses the molecular control of chemistry to effect macroscopic changes in biological and physical systems. Researchers in the lab acquire expertise in synthetic organic chemistry, polymer chemistry, and chemical biology while working in several key research areas.
1) 3D Printable Cell Cultures: Several pairs of optically active compounds that associate upon irradiation with visible light have emerged from the field of optogenetics. We are developing a light-driven biochemical toolbox based on the active components of these systems. By attaching these molecules to cell surfaces and biodegradable matrix materials, we enable light-mediated control of reversible cell-cell and cell-matrix adhesion in 3D space. This strategy has far reaching implications from the culture of organelles, to the growth of cells with stringent spatially resolved matrix requirements such as beta-cells in the Islets of Langerhans.
2) Cancer Immunotherapeutics: Pro-inflammatory immunostimulants activate the immune system and typically cause systemic inflammation; this limits their clinical route of administration to topical use. Tumors evade immunosurveillance, in part, through a highly immunosuppressive tumor microenvironment. By adding targeting and burst-release functionality to pro-inflammatory immunostimulants, we can direct the resulting immune response to solid tumors, thereby overcoming the immunosuppressive microenvironment and training the body’s own immune system to raise an anti-cancer immune response.
3) Synthetic Macromolecular Asymmetry: Synthetic polymer-linked protein heterodimers represent a growing class of experimental biological therapeutics. Protein heterodimers are typically produced using combinations of grafting-from and grafting-to approaches with at least one conjugation reaction implemented post-polymerization. These multi-step procedures decrease reaction yields, necessitating extensive optimization for each reaction step. We are developing reactions that result in asymmetric radical-radical recombination and using these methodologies to form protein-polymer heterodimers in high-yielding one-pot reaction sequences.
The Mancini group is looking to hire an exceptional postdoctoral researcher and new graduate students. For information on our research group and how to apply contact Rock at firstname.lastname@example.org.
