William B. Walker III

William Walker
As a researcher I have 8 years of professional experience with expertise in molecular biology, including 4 years with genomics/transcriptomics bioinformatics-based data analysis. I have authored or co-authored 22 peer reviewed scientific articles. I am currently working as a transcriptomics and molecular biology research leader, managing my own projects as well as supervising several colleagues.


Research Methodology Expertise/Skills

• Whole Transcriptome Shotgun Sequencing (RNA-Seq), bioinformatics analyses of whole transcriptome data, qualitative and quantitative analysis of large data sets, Unix/Command Line programming, R programming

• Molecular cloning, DNA/RNA extraction/purification, end-point PCR, quantitative real-time PCR, RNA interference, fluorescent in situ hybridization and immunocytochemistry, molecular evolution/phylogenetics

• Antennal electrophysiology (EAG and SSR), plant volatile headspace extraction, insect behavioral bioassay
