Sample Letter for Graduate Assistantship – Application for TA in Introductory Biology

Dear Dr. Martinez,

I am writing to express my enthusiasm for the Teaching Assistant position in Introduction to Biology (BIO 101) for the upcoming Fall semester. As a second‑year Ph.D. candidate in Biological Sciences at Greenfield University, I bring a strong foundation in cellular biology, a passion for mentorship, and a record of successful teaching support.

During my master’s program at Lakeside College, I served as a TA for Advanced Ecology, handling 120 students weekly. My responsibilities included grading, leading discussion sections, and creating interactive quizzes that improved average final scores by 15%. Faculty evaluations commended my clear explanations and patience, with a 4.8/5.0 student satisfaction rating.

Beyond coursework, I co‑authored a paper on ectomycorrhizal fungi now published in Mycology Today, demonstrating my research acumen and ability to explain complex concepts simply. I also develop supplementary lab slides that students find helpful, a skill that aligns with BIO 101’s emphasis on hands‑on learning.

I am available for an interview at your convenience and can start immediately in August. Thank you for considering my application—I look forward to contributing to the department’s mission of fostering curiosity and scientific literacy.

Sincerely,
Alexandra L. Reyes, Ph.D. Candidate

Sample Letter for Graduate Assistantship – Research Assistant Seeking Funding to Study Climate Change on Aquatic Ecosystems

To Whom It May Concern,

I am excited to apply for the Graduate Assistantship in the Aquatic Ecology Lab under Dr. Kumar. As a first‑year Ph.D. student specializing in freshwater microbiology at the University of Oceanview, I aim to deepen my research on microbial responses to rising temperatures.

Last year, I was awarded a $12,000 summer research grant from the National Science Foundation to develop a microbial assay for detecting early signs of cyanobacterial blooms. My role encompassed experimental design, data collection, and lab maintenance, resulting in a manuscript accepted by Environmental Microbiology. Through this experience, I mastered high‑throughput sequencing and bioinformatics pipelines, skills transferable to the Aquatic Ecology Lab’s projects.

My lab proficiency includes:

Microscopy and staining protocols—10% error rate on sample prep.
Data analysis with R and Python—data sets of >1 TB.
Grant writing—drafted two successful proposals with a combined $35,000 of funding.

I am eager to contribute my technical expertise while learning from Dr. Kumar’s pioneering work on climate‑induced microbial dynamics. I would welcome the opportunity to discuss how my background aligns with the lab’s goals.

Thank you for your time and consideration.

Best regards,
Jin‑Han Lee, Ph.D. Candidate
