Pursuing a PhD is a significant step in your academic and professional career. It requires dedication, passion, and a strong commitment to research. One of the key documents that can set you apart from other candidates is a motivation letter for a PhD application.

What is a motivation letter for PhD?

A motivation letter for a PhD is preferably 1page document that you add to anapplication to a doctoral program or if you apply for a PhD position in a particular laboratory. Its main goal is to provide a narrative that connects your academic background, research interests, and career aspirations to the specific PhD program you are applying for. Unlike a CV, which lists your qualifications and experience, a motivation letter allows you to express why you are passionate about your field of study and how you align with the program’s goals.

In this letter, you need to demonstrate your knowledge of the subject, readiness for independent research, and how you fit within the department or laboratory. It's your chance to convince the admissions committee or a Principal Investigator (PI) that you are the ideal candidate for their program.

Why write a motivation letter for a PhD?

Writing a motivation letter is crucial for several reasons:

  1. It demonstrates your passion and commitment to the field. A well-writtenmotivation letter shows that you are deeply interested in the subject and have a clear vision for your research.
  2. It highlights your research interests and how they align with the program. Admissions committees or PIs look for candidates whose research goals and experience align with the expertise of their laboratory and the department’s focus areas.

Since many PhD positionsreceive hundreds of applications, a strong motivation letter can help you stand out by showing your unique perspective and enthusiasm for your chosen field.

How to write a motivation letter for PhD

Introduction: who you are and your academic background

Start your letter with a brief introduction about yourself. Mention your name, current academic standing, and the degree you have obtained. Include any relevant details about your academic background, such as specific the name of you supervisor during the MCs program, research experience, significant academic achievements, or professional accomplishments that are directly related to your PhD field.Β 

If you’re aiming to work with a particular PI, your chances of having your email read will be higher if you mention someone you’ve worked with before in the first line. In my experience, the best results came when I started a motivational letter by mentioning a mutual acquaintance.Β 

Some PhD programs, particularly in Life Sciences, offer a salary. However, competition for scholarships that cover at least part of your salary is tough. If you’re fortunate enough to secure one, it’sa good idea to mention it in the first paragraph of your application to catch the attention of the PI.

Example: "I did my Master's thesis in the laboratory of Dr. Anderson at XYZ University, where I studied how mutations in gene Kled to development of orphan diseases in children. Working there, I obtained excellent skills in Biochemistry and Molecular Biology methods such as molecular cloning, PCR and western blotting. Throughout mystudies, I have been deeply engaged in research that explores the genetic basis of rare diseases and I would like to continue my research in your laboratory. I have obtained a scholarship from ABC for 4 years and would be happy to discuss my candidacy to do this project in your laboratory."

Research interests and future goals

This section should explain your research interests in detail. What topics are you passionate about, and why? How do these interests align with the specific PhD program you're applying to? Discuss your long-term career goals and how the PhD will help you achieve them.To increase your chances of being accepted, do the homework and read thoroughly about research a specific laboratory does, and how you can contribute.

Example: "My primary research interest lies in understanding the genetic factors that contribute to neurodegenerative diseases. I am particularly drawn to your program because of the innovative research being conducted by Dr. Smith’s lab on gene therapy approaches, which aligns perfectly with my goal of contributing to groundbreaking treatments for neurological disorders."

Previous research experience and skills

Highlight any relevant research experience, including any publications, conferences, or significant projects. This is where you demonstrate your preparedness for a PhD. Discuss specific skills you have acquired that will help you succeed in the program, such as data analysis, lab techniques, or academic writing.

Example: "During my Master's program, I conducted research on the role of epigenetics in cancer development, which was published in the Journal of Molecular Biology. I have also presented my findings at the International Conference on Genetic Research, which further refined my research and presentation skills."

Demonstrating your fit for the program

Discuss personal qualities or experiences that make you a good fit for the program. Explain how you can contribute to the department or laboratory through your unique perspective, skills, or collaborative approach.Β 

It’sbeneficial if you can prepare a project proposal, PIs appreciate independent students the most.At the end, after defending your PhD thesis, you become a researcher who must demonstratethe ability to conduct independent research.

Example: "I am a proactive researcher with a collaborative spirit, thriving in teamwork. I am confident that my background in molecular genetics and my commitment to scientific inquiry will make me a valuable addition to your research team. I would like to discuss the idea of how protein A interacts with protein B in cell type X and how it leads to mutation in gene K".

PhD cover letter example

Here is an example of a good PhD motivation letter to give you a better idea of how to structure yours:


[Your Name]
[Email Address]
[Phone Number]
Β 

Dear Members of the Admissions Committee / Dear Dr. Trinity,

I am writing to express my interest in the PhD program in [Field] at [University Name]. As a recent graduate with a Master's degree in [Your Field] from [Your University], I am eager to continue my academic journey and contribute to groundbreaking research in [Specific Research Area]. My academic background in [Specific Field] and research experience in [Specific Research Focus] have equipped me with a solid foundation to excel in this program.

[Continue with your personal motivations, research interests, alignment with the program, relevant experiences, and conclusion.]

Thank you for considering my application. I am looking forward to the opportunity to discuss how my background, skills, and passion align with your program’s goals.
