- My research focuses on the application of bioinformatics, genomics, and molecular biology to study microbial diversity, synthetic biology, and to screen for bacteria with antibiotic properties against known antibiotic-resistant pathogens. My research has been done with undergraduate students through course-based undergraduate research experiences (CURE) and independent undergraduate research.
- Current Research Interests 1. Synthetic Biology- Construction of bacterial biosensors using BioBricks (www. parts.igem.org). BioBricks are DNA fragments that have defined functions that will be used to design and build simple gene circuits to carry out a particular function such as a biosensor. 2. Identification and cultivation of endogenous plant growth promoting rhizosphere bacteria (PGPR) to enhance plant growth. This project will examine the role of endogenous PGPR in agroecosystems by determining the microbe-induced changes in microbial community structure in soil and plant roots (microbiome) and relate these changes to crop yield and susceptibility to pathogens. 3. DNA Barcoding- PCR amplification and use of DNA barcoding for species identification in various research applications such as curation of herbarial collections in the Philippines, identification and species discovery of mushrooms in the Northern New York, and ecological studies. 4. Screening for bacteria with antimicrobial properties- Isolate and characterize bacteria, from soil samples and plant roots, with antibacterial properties against bacterial pathogens known for antibacterial resistance and nosocomial infections (ESKAPE pathogens).
