Dr. Garcia-Mata's research centers on the molecular mechanisms of Rho GTPase regulation, especially RhoG, and their impact on cell behavior in both normal and cancerous contexts. His lab studies how Rho GTPases control cytoskeletal organization, cell polarity, adhesion, and migration, with a strong focus on invadopodia formation during cancer invasion. Key areas include the Scribble/SGEF/Dlg1 complex, RhoGEFs and RhoGAPs, and signaling pathways driving metastasis in breast and lung cancers. Using advanced microscopy and molecular techniques, his team explores how deregulation of these pathways contributes to tumor progression.

His most recent publications (2022–2024) highlight a consistent focus on RhoGAPs in cancer, epithelial junction stability, invadopodia regulation, and the development of biosensors for active GTPases. These works reflect a trajectory toward understanding the therapeutic potential of targeting Rho signaling components and improving experimental methodologies in cell signaling research.

Dr. Garcia-Mata has mentored numerous graduate and undergraduate students, including PhD candidates and postdoctoral researchers. While no specific scientific awards are listed in the provided text, his sustained NIH funding and high-impact publications indicate recognition in the field. His lab contributes to collaborative science and public engagement through initiatives like the CellulART Gallery.

The Garcia-Mata Lab operates within the Department of Biological Sciences and is equipped for advanced cell biology research, including studies on protein complexes, signaling dynamics, and cancer cell behavior. The lab actively publishes and trains the next generation of scientists, maintaining a central role in the university’s research ecosystem.
