A strong research introduction is not a compressed CV. It is a short explanation of the problem you study, the evidence that you can work on it, why the recipient is relevant, and what you want to happen next.
Start with the recipient's decision
Before writing, identify the decision the recipient must make. A potential supervisor may decide whether your interests fit their group. A collaborator may decide whether your skills complement an unfinished project. A mentor may decide whether they can answer a technical question. When the desired decision is unclear, the message usually becomes a list of qualifications rather than a useful introduction.
Use four pieces of information
A concise introduction normally needs four parts. First, identify your current stage and field. Second, describe one specific research problem rather than several broad interests. Third, provide one or two pieces of evidence, such as a thesis topic, publication, dataset, experiment, or technical skill. Fourth, state one clear request. Each part should earn its place by helping the recipient understand relevance.
Replace broad claims with precise evidence
Phrases such as “I am passionate about AI” or “your research is very interesting” do not help a recipient judge fit. Replace them with a concrete connection. For example: “My master's work evaluated lightweight convolutional models for four-class brain-tumor MRI classification, and I am interested in your group's work on clinically reliable model evaluation.” The second sentence gives the recipient a field, task, evidence, and reason for contact.
Keep the unpublished idea proportional
An initial introduction should not contain every technical detail. Describe the research problem, the proposed direction, and the part where the recipient's expertise matters. Avoid pasting a complete literature review. A focused paragraph makes it easier for the recipient to decide whether a longer discussion is worthwhile.
Make the request easy to answer
End with a request that can be answered in one sentence. Examples include asking whether the topic could fit a PhD group, whether the person is open to a short meeting, or whether they would review a one-paragraph concept. Avoid several unrelated requests in one note.
A practical structure
Use this order: current position and field; one relevant achievement; connection to the recipient's work; proposed direction; specific request. Read the final version aloud. Remove any sentence that repeats your CV, flatters without evidence, or introduces a second topic. A two-minute message is more likely to be understood than a five-minute biography.
Before sending
Verify the recipient's name and current affiliation. Check that every public profile link opens correctly. Keep your own copy because a temporary note is not an archival system. Finally, ask whether the message would still make sense if the recipient read it several days later without the surrounding chat history.
Adapt the introduction to the channel
Email, LinkedIn, and a temporary note do not need identical wording. Email needs a useful subject line and enough context to make the link trustworthy. LinkedIn needs a shorter opening because the preview is small. A ScholarBlink note can hold the focused research explanation, but the message that carries the link should still identify you and explain why the recipient is receiving it. Never send a bare private link with no context.
Review tone as well as length
Professional does not mean overly formal or submissive. Use direct, respectful language and avoid exaggerated praise, urgency, or claims that the recipient is your only option. Check that the message sounds like one researcher speaking to another person rather than an automated application. A calm tone makes the specific evidence and request easier to trust.
Clarity makes a thoughtful reply easier.
