Mauricio Antunes

Assistant Professor
940-369-5457

Mauricio Antunes, Ph.D. received his B.S. degree in Agronomy and M.S. degree in Crop Sciences from the Universidade Federal de Viçosa in Brazil. He then moved to West Lafayette, Indiana, where he earned a Ph.D. degree in Plant Molecular Biology at Purdue University, under the supervision of Nick Carpita and Tom Hodges. After completing his doctoral degree, Antunes joined June Medford's group at Colorado State University as a postdoctoral fellow, where he was involved in pioneering work in plant synthetic biology to rationally engineer plants to function as sensitive and specific sensors of substances of interest to humans. After spending one year working in Maureen McCann's lab at the Center for Direct Catalytic Conversion of Biomass to Biofuels (C3Bio) at Purdue University, Antunes returned to Colorado State University in 2010 as a Research Assistant Professor in the Biology Department. In 2018, Dr. Antunes joined the Department of Biological Sciences and the BioDiscovery Institute at UNT. Dr. Antunes' lab at UNT will center on the development and application of tools from the emerging field of synthetic biology to engineer plants with novel traits that function in a predictable and tunable manner to result in improved bioproduction.

CURRENT RESEARCH INTERESTS:

  • Development of synthetic transcriptional and post-transcriptional control systems whose behavior can be modulated by specific inputs.
  • Small RNAs as mobile signaling molecules in plants.
  • Engineering complex synthetic genetic circuits to improve plant production and biosynthesis.
  • Re-wiring metabolic pathways in plants using gene regulatory controls.
