Our research laboratory is focus on Microbial biotechnology and bioprospecting. In order to isolate, characterize and manipulate microbes with biotechnological potential, we specially use microbiology, molecular biology, and biochemical approaches. We are also involved in generating metagenomic libraries from tropical habitats, searching for novel microbial groups and enzymatic activities of medical and industrial applications. The lab expertise range from the used of genetic engineering tools for DNA isolation, manipulation, and analysis, to the used of functional proteomics technologies such as phage display for the development of bioindicators. The majority of the research projects in our lab will generate nucleic acids of some sort (genes), and metabolites that will require the in silico analysis
