I'd like to thank you for talking with me about the research- assistant position in your seismology lab. I truly appreciate all the time and care you took in telling me about the job and learning more about me.
I'm so pleased that you agree that my senior research project in seismology provides me with excellent experience for this position. I am eager to bring my passion for seismology to the research-assistant position, and I am convinced the knowledge and experience I've already cultivated make me the best researcher for the job.
