Dr. Maduro studies the developmental mechanisms of cell fate specification in the nematode C. elegans and its close relatives. He is interested in the regulatory gene network that specifies the embryonic mesoderm (MS) and endoderm (E) precursor cells as a model of the gene networks that act during development in many other systems. The regulators MED-1 and MED-2 function together with the evolutionarily conserved Wnt pathway in a complex gene regulatory network to specify these cells. Current work involves characterization of mechanisms by which embryos overcome stochastic differences in gene expression, as well as examining evolutionary differences in contributions made by orthologs of endomesoderm regulators in related nematodes. Dr. Maduro also has collaborations with other groups at UCR that use C. elegans to study such areas as microbial pathogenesis, fertilization and microfluidics. The C. elegans model system features a rich repertoire of tools for gene analysis, such as a complete genome sequence, transgenesis, functional genomics, and reverse genetics, and it is possible to get answers to biological questions on a short timescale.

Dr.  Maduro participates in the Cell, Molecular, and Developmental Biology and Genetics, Genomics and Bioinformatics graduate programs, and is a cooperating faculty member with the Department of Nematology.
