Research interests

My main research focus is to develop molecular methods for clinical parasites diagnosis. Molecular diagnosis method development is based on polymerase chain reaction (PCR) technique which is used to amplify or copy nucleic acid. Rapidly accumulating genomic data on parasites are used to design PCR primers directed towards multi-copy gene targets such as the ribosomal and mitochondrial genes, which further improve the sensitivity. Multiplex nucleic acid amplification technology allows simultaneous detection of many parasitic species within a single clinical specimen. For PCR products detection, specific techniques like intercalating agents, methods including fluorescence polarization, TaqMan probes, and Molecular Beacons, are desirable for human diagnostics.

Targets: Malaria parasites (P.  falciparum, P.  vivax, P.  ovale curtisi, P.  ovale wallikeri, P.  malariae and P.  Knowlesi); Diarrheal parasites (Dientamoeba, Entamoeba, Cryptosporidium, Blastocystis, Giardia); Amoebae (Acanthamoeba, Naegleria, Balamuthia)

Techniques, methods & infrastructure

DNA and RNA extraction using commercial kits; Target selection and primer design using online databases, BioEdit and Primer3 softwares; Assays development, optimization and validation using clinical samples, and conventional PCR and real time PCR techniques and instruments. Reference plasmids production by cloning for the assays validation and quatification.
