Contacting a professor before graduate admission can be valuable in research-intensive Korean master’s and PhD programs, but it is not a universal requirement. Some departments assign advisors after admission, while others expect applicants to identify or list prospective supervisors. The best approach is to read the department’s current admissions instructions first, then send a short, research-specific email when contact is appropriate.
If you are applying to a research-based master’s or PhD program in Korea, one question appears repeatedly:
Should I email a professor before I apply?
Sometimes the answer is yes.
Sometimes it is optional.
And in some programs, advisor assignment happens after admission.
The correct strategy is to understand the admissions structure of the department first and contact professors only when it adds value.
ㅤ
Professor Contact Is Not a National Requirement
There is no Korean national rule requiring every graduate applicant to obtain a professor’s approval before applying.
Admissions systems differ by university, department, and degree.
KAIST’s current graduate information, for example, tells applicants to refer to individual department and program websites for faculty information, while its administrative guidance notes that advisor and laboratory assignment can be handled by departments, including after admission in some cases.
POSTECH, by contrast, currently uses prospective-advisor information in some international graduate application processes, including a 2026 K-GKS application that required applicants to submit a list of desired professors.
These examples show why the first step is always to read the specific department’s current instructions.
ㅤ
When Contacting a Professor Is Especially Important
Professor contact is often most useful when:
You are applying for a PhD / the degree is research-intensive / you need a laboratory / the professor controls research funding / the department asks for a prospective advisor / your proposed research is highly specialized
In these situations, knowing whether the professor is accepting students can prevent you from applying to a program where no suitable supervision is available.
ㅤ
When Professor Contact May Be Less Important
Contact may be less important in:
Coursework-focused master’s programs / professional graduate schools / MBA programs / programs that admit students centrally and assign supervisors later
If the admissions guide says that students choose advisors after enrollment, do not assume that pre-admission professor approval is necessary.
Follow the actual process rather than copying advice from applicants in another department.
ㅤ
Check the Department Website First
Before emailing anyone, confirm:
Degree offered / research areas / faculty list / admission cycle / advisor-selection procedure / whether faculty are accepting students / required application documents
KAIST’s current international graduate admissions site specifically directs applicants to department and program websites for faculty information.
This is more reliable than choosing a professor only from an old publication or third-party profile.
ㅤ
Read the Professor’s Recent Work
Do not contact a professor simply because the research field sounds interesting.
Read several recent publications, laboratory project descriptions, conference papers, or research-center pages.
You should be able to explain in one or two sentences how your background or proposed research connects with the professor’s current work.
The email should make it obvious that you chose the professor deliberately.
ㅤ
Check Whether the Professor Is Still Active in That Area
Faculty research can change.
A professor may have published heavily in one topic five years ago but now work on a different area.
They may also be on sabbatical, approaching retirement, moving institutions, or temporarily not taking new graduate students.
Use the most recent available information rather than relying only on an old paper.
ㅤ
What Your First Email Should Achieve
The first email does not need to tell your entire life story.
It should answer four questions:
Who are you? / What is your academic or research background? / Why are you contacting this professor specifically? / What are you asking?
A professor should be able to understand your purpose in less than a minute.
ㅤ
A Good Email Structure
A practical first email can follow this structure:
Subject — Prospective PhD Applicant for Fall 2027 – Research Interest in [Topic]
Opening — Brief introduction with current university, degree, and intended application semester
Research fit — One or two sentences connecting your background to the professor’s recent research
Your plan — Brief description of the research direction you want to pursue
Question — Ask whether the professor expects to accept graduate students and whether your research interests could fit the group
Closing — Thank the professor and mention attached CV or other concise material
Keep the message focused.
ㅤ
Use a Specific Subject Line
Avoid vague subjects such as:
Hello Professor
Scholarship Inquiry
Need Admission
A better subject makes your purpose immediately clear.
Examples:
Prospective Master’s Applicant – Fall 2027 – Robotics
Prospective PhD Applicant – Computer Vision Research
Graduate Applicant Inquiry – Renewable Energy Systems
The subject should help the professor identify your field and application timing.
ㅤ
Introduce Yourself in One or Two Sentences
The professor does not need your full biography.
Include only the information needed to understand your academic position.
For example:
‘I am completing a master’s degree in Mechanical Engineering at X University and plan to apply for the Fall 2027 PhD admission cycle.’
Then move quickly to research fit.
ㅤ
Show Research Fit, Not Flattery
Avoid sentences such as:
‘You are a world-famous professor and it is my dream to study under you.’
They provide no evidence that you understand the research.
Instead, refer briefly to a specific research theme, project, or recent publication and explain why it connects with your own work.
The goal is not to impress the professor with praise.
It is to demonstrate academic fit.
ㅤ
Explain Your Research Background Briefly
Mention the strongest evidence that you can contribute to the research group.
This might include:
Master’s thesis / undergraduate research / laboratory work / publication / conference paper / data analysis / programming / fieldwork / professional research experience
Choose the two or three most relevant points.
Do not copy your entire CV into the email.
ㅤ
Attach a Concise Academic CV
An academic CV is usually the most useful attachment for the first contact.
It can include:
Education / GPA where useful / thesis / research experience / publications / conference presentations / technical skills / awards / language qualifications
Keep it readable.
The professor should be able to scan it quickly.
ㅤ
Should You Attach a Research Proposal?
It depends.
If the department expects a formal proposal or you already have a well-developed doctoral research direction, a short proposal can be useful.
For an initial contact, however, sending a long 10- or 20-page document may be unnecessary unless requested.
A one- or two-page research summary can often be more practical.
Follow the discipline and department conventions.
ㅤ
Do Not Attach Too Many Files
Avoid sending:
CV / transcript / passport / certificates / ten publications / long thesis / recommendation letters
all in the first email unless the professor or department specifically asks for them.
A concise CV and, where relevant, a short research summary are usually enough to begin the conversation.
You can send additional documents later.
ㅤ
Should You Mention Your GPA?
If your GPA is strong and relevant, you can include it briefly in the CV.
You usually do not need to lead the email with your GPA.
Research fit, academic background, and the reason for contacting the professor are generally more important in a supervisor inquiry.
ㅤ
When to Ask About Funding
Funding is an important question, especially for PhD applicants.
But your first sentence should not be:
‘How much stipend can you give me?’
First establish research fit.
After explaining your background, it is reasonable to ask whether funded graduate positions or research assistant opportunities are expected to be available for the intended semester.
If the professor shows interest, then confirm the exact tuition and stipend arrangement before accepting an offer.
ㅤ
Ask About Availability, Not Admission Guarantees
A professor may be able to tell you whether they are accepting students, but that does not necessarily mean they can guarantee formal admission.
Graduate admission may still require evaluation by a department or university committee.
Phrase your question appropriately:
‘Do you expect to accept new PhD students for Fall 2027?’
is better than:
‘Can you guarantee my admission?’
ㅤ
A Positive Reply Is Not the Same as Admission
A professor may say:
Your background looks relevant / please apply / I expect to have an opening / we can discuss after admission
These are encouraging responses.
But unless the university’s formal process explicitly gives the professor authority to make an admission offer, you still need to complete the official application and evaluation.
Do not make financial or travel commitments based only on an informal email.
ㅤ
What If the Professor Does Not Reply?
Professors receive large numbers of emails.
No reply does not automatically mean rejection.
Wait about one week, then send one short follow-up.
If there is still no response, move on unless the department specifically requires that professor’s approval.
Repeated emails every day are more likely to damage your impression than improve it.
ㅤ
One Follow-Up Is Usually Enough
A follow-up can be very short.
Remind the professor of the original message, your intended admission semester, and your research area.
Do not rewrite the entire first email.
If the professor still does not respond, respect the lack of response.
ㅤ
Do Not Email Every Professor in the Department at Once
Mass-emailing ten professors with the same message is easy to detect.
Faculty members within the same department may communicate with one another.
Choose professors whose research genuinely matches yours.
If several are relevant, customize each email substantially and avoid creating the impression that you are simply searching for anyone who will fund you.
ㅤ
Avoid Copy-and-Paste Errors
One of the worst mistakes is sending an email with:
The wrong professor’s name / the wrong university / the wrong research field / another school’s program name
These mistakes immediately signal that the message is generic.
Check the email carefully before sending.
ㅤ
Use Professional English
You do not need perfect English.
You need clear, professional communication.
Keep sentences short.
Avoid excessive formality, emotional language, emojis, or casual messaging style.
Use the professor’s academic title correctly and close politely.
ㅤ
Should You Write in Korean?
If the professor and program operate mainly in Korean and your Korean is strong enough for academic communication, Korean may be appropriate.
For English-taught international programs, professional English is normally acceptable.
Do not use machine-translated Korean simply to appear more serious if you cannot actually communicate at that level.
The language of the email should match the academic environment you are applying to.
ㅤ
Professor Contact Can Help You Evaluate the Program Too
The conversation is not only about convincing the professor to accept you.
You are also evaluating whether the research group is right for you.
Pay attention to:
Response clarity / research alignment / funding explanation / supervision expectations / communication style
If the professor is interested, ask whether you can speak with current students before making a final decision.
ㅤ
Ask Current Students After Initial Contact
Current students can help you understand:
Supervisor availability / laboratory culture / stipend reliability / working hours / publication expectations / average graduation time
This information is especially important for PhD applicants.
A short conversation with current students can reveal more about daily research life than an admissions brochure.
ㅤ
Some Universities Ask for Prospective Advisors Formally
In some admissions routes, potential-supervisor information is part of the application itself.
POSTECH’s 2026 K-GKS University Track, for example, required applicants to submit a Prospective Advisor List based on the university’s published list of available advisors.
When a university provides an official advisor list or form, use it exactly as instructed rather than relying only on informal email contact.
ㅤ
Other Universities May Assign Advisors After Admission
The opposite model also exists.
KAIST’s current graduate administrative information states that matters such as academic advisor and laboratory assignment are handled through department offices, and its guidance includes advisor or lab assignment after admission in relevant cases.
This reinforces a central rule:
Do not assume that professor contact works the same way at every Korean graduate school.
ㅤ
A Practical Professor-Contact Process
A good process is:
Choose your research field → shortlist departments → identify 2-5 genuinely relevant professors → read recent research → check admissions rules → prepare academic CV → write a customized email → wait about one week → send one follow-up if needed → continue with formal application
This process is much more effective than sending dozens of generic emails.
ㅤ
FAQ
Do I have to contact a professor before applying to graduate school in Korea?
No. There is no universal requirement. The importance of professor contact depends on the university, department, and degree.
