Molecular Biologist Cover Letter Example & Writing Guide (2026)

Dear Dr. Patel, I am excited to apply for the Senior Molecular Biologist position in the Target Validation group at Apex Genomics. With six years of postdoctoral and industry experience in functional genomics and molecular target discovery, I bring a proven record of identifying and validating novel therapeutic targets. My work has directly contributed to two preclinical programs and resulted in nine peer-reviewed publications, including three first-author papers. In my current role at Helix BioSciences, I lead CRISPR screening campaigns to identify genetic vulnerabilities in solid tumor models. I designed and executed a genome-wide CRISPR knockout screen in pancreatic cancer organoids that identified three novel synthetic lethal targets, one of which is now being pursued as a drug discovery program. I also established our lab's long-read sequencing capability using Oxford Nanopore technology, enabling structural variant detection that was previously invisible to short-read approaches. My technical expertise spans CRISPR engineering, RNA-seq, ChIP-seq, single-cell multi-omics, and high-content imaging. Apex Genomics' data-driven approach to target identification and your integration of functional genomics with computational biology is precisely the type of environment where I excel. I am confident that my experimental design skills and genomics expertise would accelerate your target validation efforts. Thank you for your time and consideration. I look forward to discussing this opportunity. Best regards, David Okafor
