Current research and/or projects
Dr. Mechai has an excellent knowledge on molecular laboratory work, sequence manipulation, bioinformatics analyses, and phylogenetic analyses. His background in applied entomology and bioinformatics gives him a relevant multidisciplinary skill set: field entomological skills, taxonomic skills in entomology, statistical analysis skills, and geomatics skills.
Research and/or project statements
- Works at a multidisciplinary crossroads with multiple expertise (genomics, geomatics and spatial modelling) needed to develop new ideas on the application of the epidemiological surveillance in the context of climate change.
- Uses next-generation sequencing technology to investigate the whole accessory genome of the bacterium causing Lyme disease in Canada
- Developing and optimizing the protocol of identification of mosquitoes and mosquito-borne viruses in the frame of GRDI-Ecobiomics project using NGS and metagenomics tools
- Innovates ways to improve surveillance systems for tick-borne and mosquito-borne diseases
