More than 90 supervisors from 14 institutions are currently affiliated to FoodHealth.

FoodHealth supervisors affiliated with University of Helsinki can be found in the Researh portal of University of Helsinki.

Please note that the list includes both students and supervisors. If you're looking for a potential supervisor, look for people having 'Supervisor in doctoral programme' title.

    Guidelines for the examination of doctoral dissertations

    Guidelines for the examination in the Faculty of Agriculture and Forestry
    Guidelines for the examination in the Faculty of Veterinary Medicine


    It is important to allow enough time for all the bureaucratical steps before and after the public examination of your dissertation. Please refer to the website of your faculty with the latest information on the steps towards graduation. In general, doctoral dissertations are discussed in two faculty council meetings before the public examination and in one after the examination. So, when planning your schedule it is good to check the dates of the faculty council meetings well in advance.

    Please, note that all the courses must be completed and registered in WebOodi before leaving the thesis for the pre-examination.

    In the first faculty council meeting the pre-examiners of the dissertation are appointed. After this, in the second faculty council meeting the student is granted with the permission to defend the dissertation in a public examination, and the opponent and custodian are appointed. Finally, after the defence the dissertation is approved and graded in the third faculty council meeting.

    Rember also that the doctor's diploma is not issued automatically but must be requested using a form available at the faculty homepage.

    YEB doc­toral dis­ser­ta­tion series

    The Doctoral School in Environmental, Food and Biological Sciences (YEB) has its own series in which docotral candidates can publish their doctoral thesis. Students choosing to publish their thesis in the series will receive assistance with the cover design of the thesis and all other practical matters regarding the publication of the thesis. The thesis can also be published in other series or without a series.

    More information on how to publish a thesis in the YEB series is available here.

    The pub­lic ex­am­in­a­tion

    When the time to defend your thesis is getting closer you should familiarize yourself with both the university and faculty instructions. In the university instructions for public examination you can find useful information on public examination.


    The post-doctoral party, or karonkka, is an academic tradition that marks the end of the dissertation process. The doctoral candidate arranges the karonkka to thank the opponent, the custodian and others who have contributed to the work. In addition to them, the invitees to the post-doctoral party should include professors working in the field of the dissertation and others who have aided in the dissertation work. Nowadays, doctoral candidates may invite friends and family along with members of the academic community to this party.

    You can find information on the karonkka traditions at the University of Helsinki webpage. The site gives useful tips on things such as:

    • invitations to the party
    • dress code
    • seating arrangements
    • programme of the party

    It is also a good idea to talk with your friends who have defended recently and ask them for advice. The doctoral programme coordinator may also give some tips.

    And lastly, a few things to consider. Towards the end of the spring and autumn term there will be more and more doctoral candidates defending their theses. Furthermore, during summertime there are weddings and before Christmas there are Christmas parties. Thus it is good to book the lecture hall as well as the banquet facility well in advance.

    While searching for a banquet facility you might find the City of Helsinki meeting planners' site and the GoExperience site useful. In some places you are allowed to organise the catering as you like, while in some you must get the dinner from the facility. If the catering is unrestricted, you can ask around for a good catering company or google for one. Some banquet facilities may also be able to recommend catering companies.

    Once the menu is finalised you may go to Alko with it to get tips on wines to go with the food. The staff knows their wines very well and can also help you on deciding how much you need.

    If you want to follow the old karonkka traditions your guest of honor, the opponent, should be seated on your right and the custodian on your left. Your primary supervisor should be seated to the second chair on your right and possible other supervisors to the second chair on your left, to the third chair on your right etc. If the pre-examiners of your thesis attend the karonkka they should be seated after the opponent and the custodian in which case the supervisors are seated to the following chairs on the right and left.

    For the speech it is a good idea to write yourself a little list of people you want to thank. Giving the speech may be a very emotional moment and an important name might slip out of your mind. Reserve a handkerchief for yourself too as tears are not a rarity in karonkkas.

    It is a custom to tinkle a glass with a spoon to let people know you are about that start your speech. You should start your speech by first thanking and proposing a toast to your opponent and then to the custodian, followed by your supervisors and others you wish to thank. You may also give a little gift to the opponent, the custodian and your supervisors. The opponent, the custodian and your supervisors will reply in the same order you mentioned their names. Many people will reply to you but some may choose not to do so.

    Good luck with everything!


    Since the founding of the doctoral programme in 2014 more than 50 doctoral candidates have graduated from FoodHealth. Below you can find all FoodHealth dissertations and the date of defense.

    Minisym­po­sia prior to doc­toral de­fence

    FoodHealth encourages doctoral candidates to organise a minisymposium prior to their doctoral defence and provides funding for it on the condition that the candidate - not the thesis supervisor - takes the main responsibility of organising the event.

    The topic of the minisymposium must be wider than the title of the candidate's PhD thesis and be of general interest. The minisymposium must be at least a half-day-event with 3-4 presenters. The speakers of the minisymposium may include, for example, the defence opponent, dissertation pre-examiners and other scientists working in the field of the minisymposium.

    The maximum sum of the funding is 1000 € per symposium and it can be used for speakers' travel and accommodation expenses as well as for the symposium coffee service. Planning officer of FoodHealth or coordinator of YEB Doctoral School can help with the arrangements if needed.

    Funding for a minisymposium must be applied at least six weeks before the planned symposium date. To apply, please send the doctoral programme planning officer (foodhealth-info(a) a free-form application with the following:

    • The title of your PhD thesis
    • The title and a short description of the minisymposium including its scientific relevance
    • A tentative list of invited speakers and the topic they are asked to cover in their talk (the exact titles of the talks can be decided later on)
    • A budget for the minisymposium including the speakers' travel and accommodation costs

    After funding is secured you should book a room for the symposium and advertise it. An advertisement should be delivered to the planning officer who will post it on FoodHealth's homepage and to relevant email-lists.


    Lists for doc­toral can­did­ates

    All FoodHealth doctoral candidates should join the Foodhealth-mail1(at) mailing list, which is used to advertise FoodHealth's activities as well as to distribute information relevant to PhD candidates.
