University of Helsinki Chemistry Master’s Thesis Guide 2026-2027

The Master’s Programme in Chemistry at the University of Helsinki combines advanced chemistry coursework with a substantial research project and a 30 ECTS Master’s thesis. The current programme was previously called the Master’s Programme in Chemistry and Molecular Sciences, which matters because some current University thesis instructions still display the legacy CHEMO name even though the public programme is now called Chemistry.

This guide uses current University of Helsinki programme pages, the current degree-code-selected Chemistry thesis instructions, the Department of Chemistry’s thesis guide linked from those instructions, and the 2026-2027 Faculty of Science timetable. It is a thesis guide, not an admissions guide. Application criteria, fees, scholarships, eligibility and language-test requirements are intentionally outside this article.

Current Chemistry programme structure

The degree is 120 ECTS and is intended to be completed in two academic years. Instruction is in English, while current programme rules also allow courses and the Master’s thesis to be completed in Finnish or Swedish.

The current programme has two study tracks:

1. Chemistry
2. Circular Economy and Sustainable Chemistry

Within Circular Economy and Sustainable Chemistry, the current programme page presents two study paths: Sustainable chemistry researcher and Sustainable chemistry expert.

Current programme structure places 85-120 ECTS in advanced Chemistry studies. The advanced studies include the KEM390 Master’s thesis, 30 ECTS, the KEM416 Master’s Seminar, 5 ECTS, and, in the normal Chemistry structure, the KEM412 Research Project, 15 ECTS. Other elective studies account for 0-35 ECTS depending on the student’s structure and supplementary-study requirements.

The Research Project needs one important qualification: current programme guidance says it is usually an extension of the Master’s thesis and is mandatory unless the programme requires more than 15 ECTS of supplementary Chemistry studies. So students should check their own Sisu structure rather than assuming every transcript must look identical.

The 30 ECTS thesis and the 15 ECTS Research Project are related, but not identical

The Master’s thesis itself is 30 ECTS. Current Chemistry guidance says it includes a literature review and an experimental or theoretical/computational research component. The student must demonstrably complete part of the research and write the thesis independently, even when the research is carried out inside a larger project or research group.

The 15 ECTS Research Project (KEM412) can be an extension of the research component of the thesis or, under the current programme description, an independent research project. Where KEM412 is part of the student’s structure and is connected to the thesis topic, the combined thesis/research package is effectively about 45 ECTS.

That distinction is useful when planning workload. The thesis is the assessed written Master’s thesis. The Research Project is a separate study unit, even when the practical research is tightly integrated with the thesis topic.

Plan roughly 6-7 months for the combined thesis and research process

The Chemistry-specific thesis instructions currently advise students to allocate about 6-7 months to complete the thesis process. Within that period, roughly 4-5 months are normally devoted to the research work, including the Research Project where it applies.

To graduate within the planned two-year degree period, the programme recommends starting the research part in the autumn term of the second year. It is therefore sensible to start asking about possible research-group positions toward the end of the first year or during the summer before the second year.

A practical planning sequence is:

1. identify the chemistry area or research group that fits your completed studies;
2. contact a relevant professor, group leader or researcher;
3. agree the topic and supervision arrangements;
4. complete the supervision plan before officially starting;
5. agree the research timetable, data or laboratory work, writing milestones and meetings;
6. carry out the practical/theoretical/computational research while keeping organised records;
7. begin the literature review and thesis writing before the research period is over;
8. leave time for supervisor feedback, maturity test and formal E-thesis submission.

The current guidance describes thesis/research work as typically full-time, although some courses can be completed at the same time if this is agreed with the supervisor early enough.

Choosing a topic and supervisor

Chemistry thesis research is often carried out in a research group at the Department of Chemistry, but current programme guidance also allows research elsewhere at the University, in a research institute or company, and in some cases during student exchange.

If the thesis research is completed inside the Department, the supervisor will normally come from the selected research group. Students are not necessarily expected to arrive with a fully formed thesis topic: the programme-specific guidance says a research group will often provide or help define the topic.

If the thesis is completed outside the Department of Chemistry, the current Chemistry instructions require two supervisors: an external advisor and a professor from the Department of Chemistry who represents the Master’s programme. In this situation, the supervision plan becomes especially important because it should clarify meetings, responsibilities, use of research data and questions of disclosure or publication.

Chemistry has an actual page-length boundary, but 40-50 pages is not a target

The Department’s current-linked Thesis guide for chemistry (2024) gives more specific length guidance than many other Helsinki programmes.

It says that the appropriate length depends on the nature and amount of the material. Different types of experimental, theoretical or computational work can require different amounts of space. The guide states that a Chemistry Master’s thesis does not exceed 80 pages. It also says that a well-made thesis of 40-50 pages can completely fulfil the requirements of an excellent thesis.

Those statements should not be converted into a rule saying every thesis must be 40-50 pages. The better interpretation is:

• 80 pages is the Chemistry guide’s upper boundary;
• 40-50 pages is an example of a length that can be fully sufficient for excellent work;
• the actual length should match the research question, evidence, methods, results and discussion;
• where the 15 ECTS Research Project is not part of the project, the Chemistry guide notes that the thesis may be shorter.

Appendices can be used for necessary documentation of results when appropriate.

What the written Chemistry thesis should contain

The Chemistry thesis is more than a literature review. Current programme guidance expects a literature component plus the student’s research component, which may be experimental, theoretical or computational.

The Department guide emphasises that the student should analyse the results of their own research and report them in a scientifically appropriate format. In practical terms, a strong thesis normally needs a clear research objective or question, a scholarly framework, appropriate research data or material, a transparent method, results, discussion and conclusions that distinguish the student’s findings from the existing literature.

The exact structure can vary with the project. An experimental synthesis thesis will not look identical to a computational chemistry thesis or a radiochemistry project. The method and presentation should follow the scientific logic of the work, not a generic chapter template copied from another discipline.

Reference and formatting guidance is Chemistry-specific

The current-linked Chemistry thesis guide gives concrete writing and reference instructions. It tells students to arrange references in numerical order and provides examples formatted according to the Royal Society of Chemistry model. It also discusses journal-name abbreviations, reference details, figures, tables, formulas, title page, abstract and accessible document preparation.

This is different from simply telling Chemistry students to use APA or MLA. The safest workflow is to use the current Chemistry thesis guide, current University template where suitable, and any supervisor or research-group instructions that are more specific to the project.

The 2024 guide remains linked from the current Chemistry-selected University thesis page. However, where a newer current Studies Service or programme instruction conflicts with the PDF, the newer current instruction should control.

Submission: Sisu first, then the final PDF in E-thesis

Current University rules require registration for the thesis and maturity-test submission in Sisu before final submission. The Chemistry-specific instructions additionally say that, from 1 August 2025, students must enrol for KEM390 in Sisu.

When the thesis and supervisor are ready for formal examination, the final PDF is submitted to E-thesis by the published deadline. The Chemistry instructions use a 23:59 Finnish-time cutoff.

This is a final-submission step. Once the thesis has been saved for assessment, it is no longer editable. If a substantive correction is required after formal submission, the assessment process must be stopped and the corrected thesis resubmitted according to the University’s process.

Examiners and grading

Chemistry-specific guidance states that the thesis is examined by two people. One must be a qualifying Department of Chemistry academic, such as a professor, assistant or associate professor, research director, or senior/university lecturer, and the other must have at least a doctoral degree. The thesis supervisor often acts as one examiner.

The thesis is graded on the 0-5 scale using the programme evaluation matrix. Current instructions require particularly clear justification for the extreme grades 0, 1 and 5. After the assessment is completed, the thesis moves through Student Services to the Dean, who makes the final approval and grading decision.

The evaluation focuses on the quality of the research question and objective, scientific framework and sources, research data and method, presentation and interpretation of results, discussion and conclusions, academic writing, and the work carried out during the thesis process.

Chemistry has a separate supervised maturity test

Do not assume that the thesis abstract automatically completes the maturity test in Chemistry.

The current Chemistry-specific instructions say the Master’s maturity test is a separate supervised short essay. It is normally around 1-2 pages, the student has one hour, and it must be completed before the evaluated thesis is sent for final approval by the Dean.

The exact language depends on the student’s previous degree and language background, so students should confirm the applicable language with the supervisor. The University is unambiguous on one point: AI may never be used in a maturity test.

2026-2027 Faculty of Science submission timetable

The current Chemistry-selected University instructions publish these Faculty of Science rounds for the 2026-2027 academic year:

The completed thesis must be submitted by 23:59 Finnish time on the submission date. The University also states that supervision and feedback are normally not provided in July unless specifically required, and theses are not assessed in July.

Do not plan around only the Dean-decision date. Your own internal deadline should be earlier so the supervisor has time to review the final text and so the maturity test, Sisu registration and E-thesis submission can be completed correctly.

AI, research integrity and publication

The University’s current AI policy allows AI tools to support learning and writing only within the applicable teacher, programme and faculty restrictions. Use must be disclosed when required, research-integrity principles continue to apply, and the student remains responsible for the submitted work.

For Chemistry, AI must not replace the student’s scientific reasoning, interpretation of results, source verification or independent writing. It is never permitted in the maturity test.

A Master’s thesis is a public document after approval. The E-thesis process lets the student make the relevant publication choice, and limited availability or an embargo may be possible under University and Faculty rules. But confidential information should not simply be inserted into the thesis. If the project involves a company, unpublished research or sensitive background material, discuss publication and embargo questions with the supervisor before final submission.

A practical Chemistry thesis checklist

Before formal submission, confirm that:

• your current Sisu structure shows how KEM390, KEM416 and KEM412 apply to you;
• the topic, supervisor(s) and supervision plan are agreed;
• an external project has both the external advisor and the required Department professor;
• your timetable reflects the roughly 6-7 month combined project where relevant;
• your thesis contains both the scholarly literature framework and your own research component;
• the length follows the needs of the project and stays within the Chemistry guide’s 80-page boundary rather than chasing a page target;
• references, figures, tables, formulas and formatting follow the current Chemistry guidance;
• your supervisor has reviewed the final version;
• you have completed the separate Chemistry maturity test;
• Sisu registration and KEM390 enrolment are complete;
• the final PDF is submitted to E-thesis before 23:59 Finnish time on the chosen deadline;
• you have discussed any publication limitation or embargo before submission.

The central planning principle is straightforward: treat the thesis as a 30 ECTS scientific research and writing project embedded in a larger Chemistry research process, not as a document that can be planned by page count alone.
