How do I start a Molecular Biologist cover letter?

Choose an opening paragraph that matches your experience level:

Entry Level

As an early-career molecular biologist with hands-on experience in PCR, cloning, and RNA extraction, I bring a proactive approach to learning advanced techniques and contributing to team projects. I am eager to apply my laboratory training and strong attention to detail to support your research goals.

Mid-Level

With 3–6 years of molecular biology experience, I have led protocol optimizations, supported NGS workflows, and produced reproducible data that advanced project milestones. I combine technical proficiency with collaborative problem-solving to deliver timely experimental results.

Senior Level

As a senior molecular biologist and project lead, I have guided cross-disciplinary teams, designed complex experiments (including CRISPR and NGS applications), and authored peer-reviewed publications. I focus on translating biological insight into scalable, reproducible workflows that accelerate discovery.

What achievements should I include in a Molecular Biologist cover letter?

Incorporate these results-focused statements into your cover letter:

"Optimized qPCR assays that improved sensitivity by 30% and reduced reagent costs by 15%"
"Led NGS library preparation for a 200-sample cohort, achieving >95% pass rates for sequencing quality metrics"
"Implemented CRISPR-Cas9 knockout workflows and validated gene edits by Sanger and deep sequencing"
"Published three first-author manuscripts on gene regulation and assay development"
"Developed automated sample-processing pipeline that reduced hands-on time by 40%"
"Trained and mentored five junior technicians, improving lab throughput and protocol adherence"
"Designed and executed troubleshooting protocols that identified a contamination source and restored experiment reliability"
"Maintained GLP-compliant documentation and contributed to successful internal audits"
