A strong relationship with Joensuu

Moi,

This is Joan, a Spaniard environmental scientist ,who was born some years ago in a very small village called Moixent, located in the southwestern part (the warmest area) of València, Spain. My experience in Joensuu goes back more than 5 years, when in September 2012 I landed in Helsinki after being accepted as an exchange student for the whole academic year at the University of Eastern Finland. I still remember that long journey: Moixent-Madrid-Oslo-Helsinki-Joensuu. Yes, it took more than 24 hours to arrive to my new apartment, located firstly in Tikkarinne, and later on in Karjamäentie.

New city, new people, new food, new culture, new language… and of course first time studying for part of my Bachelor’s in English (quite challenging at the beginning I must admit). Back then, I took a couple of courses in aquatic ecosystems taught by Dr. Jarkko Akkanen, who without knowing then, would later become the supervisor of my Master’s thesis. Furthermore, in one of the courses, I had the pleasure of meeting Sebastian; but, I will talk about him soon.

I hardly realized it, and May 2013 arrived.  31st of May, the time to pack, to say “see you soon” to a lot of wonderful people…It was the time to start another 24 hours’ journey back to my hometown (drama, drama), but keeping in mind just one thing: I will be back in Joensuu, sooner or later!

The last academic year of my Bachelor’s started in September 2013.  As you can imagine, half of my heart was left in this amazing city; quite close to the Russian border, and surrounded by lakes and hectares of forest where you can enjoy the Northern lights. Just one mission on my mind: get my Bachelor’s diploma as soon as possible and apply for a Master Programme at the University of Eastern Finland.

I didn’t tell anyone (not even my parents), and in May 2015 I got a letter at home: “Dear Joan, it is my pleasure to inform you that you have been accepted in a 2 years Master Programme in Environmental Science at UEF”. Yeah, August was the month to pack again, apply for a new flat and look for the fastest way to get to Joensuu. This time it took 10 hours, not bad at all (you learn from your experiences)!

The academic year started in September, and I was fully ready to meet old and new friends, learn as much as possible, and enjoy every single day of this opportunity. First year of the Master was complete, and at this point, it was the moment to choose the topic of my thesis. After being trained in different research groups, I made a decision: “I want to do the thesis in the Aquatic Ecotoxicology Group”.

So, after some informal meetings with Jarkko and Sebastian (yes, the guy that I met in 2012, became my second supervisor), we got a topic: “improved application system for activated carbon based sediment remediation”.  Briefly, we are evaluating the efficiency of granular activated carbon vs. carbon pellets to verify which one has better remediation capability (PCB bioaccumulation) by causing fewer unfriendly effects on the aquatic community (Lumbriculus variegatus has been used as toxicity test organisms). In the laboratory I had the chance to meet the other colleagues of the group: Marja, Kukka, Kaisa, Kristiina, Bhabishya, Victor and Eric. I have to thank you all for being such a great group of people and for all the help (specially, in making you some space at the office by taking boxes)!

Experiments were finished by the Ilosaarirock 2017 weekend and currently I’m in process to write the thesis. Nowadays, this process is being done in Denmark, where I moved at the beginning of January 2018 for a four months’ internship on microplastics remediation at the Nordcee Institute, University of Southern Denmark.

Don’t think I have forgotten you, because Joensuu and the Ecotox Group is each single day in my mind, and I will do my best to be back in town and continue my career with the group! Thanks all of you for accepting and for giving me all the knowledge in Aquatic Ecotoxicology!

Have a nice Spring,

Joan
