Include:
Degree names, universities
Subjects like microbiology, molecular biology, genetics
Any relevant academic awards or certifications
Short mention of academic skills (lab protocols, bioinformatics basics, etc.)
3. Research Experience
This is the core of your SOP. Go beyond your thesis title. Explain what you did, how you did it, what you learned, and what tools you used.
Data handling, analysis software, or reporting tools
Publications, posters, or conferences (if any)
4. Why This Program?
PhD programs want students who fit into their research ecosystem. This section should prove that you’ve read about their work and know how your goals connect.
Avoid phrases like “It is a reputed university.” Instead, mention:
Specific professors
Research groups or centers
Program structure (rotations, thesis flexibility, lab funding)
Tools, techniques, or areas the university focuses on
5. Research Focus
You’re not expected to submit a full proposal, but you should show clear direction. Talk about the area or question you plan to explore.
Keep it focused:
What do you want to study?
What’s the potential impact or gap you want to work on?
Are there any models, organisms, or pathways you want to explore?
6. Future Plans
Show that your goals align with the purpose of a PhD. Whether you want to work in academia, research, policy, or biotech—mention it.

“I’ve always loved science…”
Generic. No one knows what sparked your interest.
“During my MSc project on gene expression, I...”
Listing lab tools like a resume
No context. Feels flat.
“I used PCR during my thesis to amplify gene X...”
Ignoring the program/university
Looks like a mass application.
Mention labs, professors, or research focus.
Vague goals like “I want to help”
