Dear Ms. Guavera,


As a dedicated biological researcher with over 4 years of experience using skills like sequencing and sample preparation, I was happy to see your ad for a researcher at Qyl, Inc. Qyl’s research on the discovery and development of curative immune cell therapies is fascinating. To get you closer to your goals, you need a biologist who can perform DNA/RNA detection and cloning, with solid skills in teamwork and training. I think my resume will interest you.


At Fyrn, Inc., I used fully automated systems to perform multiple DNA/RNA detection tests per day. I also worked with a team of 3 research interns to conduct DNA cloning tests, and trained each of them in best practices with a 99% success rate as measured by internal KPIs. You also need someone skilled in synthesizing organic compounds, on both large and small-scale projects. One of my chief duties as a lab technician at Green Leaf Chemicals was synthesizing organic compounds. I also developed an encrypted database to compile results from our sampling and distillation processes that saved 5 hours per week.


I’m excited about Qyl’s research—and its future applications. Working at Qyl, Inc. would help me pursue my passion for cutting-edge microbiology in a way that has a positive impact on the world. Could we meet sometime next week by phone or in person to discuss how I can support your experimentation and development goals?


Best regards,


Hilaria J. Rose
