Catarina also produced Cbo DyP mutants likely to have modified distal heme pocket polarity (changed to a more hydrophobic environment).
Catarina's testimonial
"I had an opportunity to visit Gecco and work there, which is particularly priceless now when the world is still struggling with the covid pandemic, and we face numerous restrictions and limited working hours. I am thankful for this opportunity! I loved every moment of my stay in Groningen, from the people to the working place and the University; everything was amazing. The team is great, the laboratory is outstandingly equipped, the people are exceptionally nice, competent, and helpful, and the city is magical!
In this short period of three weeks, we were able to reach our rather ambitious goals. It has been a unique experience for me as a Ph.D. student, which will help me to grow as a scientist and learn the aspects of protein biochemistry that are not available at my home laboratory."

Jonathan's testimonial
"Unfortunately, the covid decided to struggle with humankind in the middle of my secondment, the first time I got the chance to cross the ocean…but an experience is an experience, isn´t it?? During the first couple of months of my secondment, I had the pleasure of working (physically) at Zymvol Biomodelling, which was extraordinary! I loved the place loved the people! I have to be honest, I was quite nervous, but this feeling disappeared as soon as we had our first beer together (after the office, of course!). Zymvol´s team is great! They are good people with a great sense of humor! I have a really good time with them! I walk to work daily to get to know the city; Barcelona is gorgeous!!! From an academic standpoint, I am quite happy that we accomplished our goals. Our problem wasn´t trivial, and much care to detail was needed. The new skills I learned are important for my training and will greatly help my Ph.D. thesis. Before this point, my work was mostly experimental, and here we change methodology 180 degrees! You know, facing the Linux terminal for the first time and learning how to move in there…baby steps at the very beginning…and soon I was doing actual things in that little black screen…yeah definitely, a great activation barrier was crossed within this period and I am thankful for that."
#9 - Lur Alonso (ZYMVOL, ES) secondment at University of Groningen, RUG, NL (Dec 2019-Dec 2020)

Work included the identification of candidate residues in the CYP222A1 interface, construction of mutants by site-directed mutagenesis, production in E. coli, and enzyme purification.
Santiago's testimonial
"The past two months have been probably the most challenging in my life. For the first time, I moved out from the city where I had lived all my life. I traveled almost 12000 kilometers to a new country and continent. For me, a different culture, a language I can't speak, a different season of the year and time zone, a city far, far away from everyone I know... And I haven't felt any regret any single time. My time here in the biochemistry department of the Technische Universität Braunschweig has been amazing so far. Dr. Anett Schallmey and everyone in her lab makes me feel very welcome. I had the opportunity of meeting new and interesting people, and I learned a lot from our cultural similarities and differences. Braunschweig is a small city in the heart of the country, and most people here are germans, so I can say without a doubt that I'm having "the full german experience." I am lucky to have enjoyed a real Deutsch Weihnachten (German Christmas) and Braunschweig's beautiful Weihnachtsmarkt (Christmas market). Being here at Christmas time and walking into a Christmas market is one of the most beautiful and interesting things to do in Germany, definitively a must if you are visiting Germany! On the other hand, the scientific experience is great as well. It is very good for Ph.D. students like me to learn new subjects, techniques, and different points of view and share ideas with new people. My background is in physical chemistry, but here I'm in a biochemistry laboratory, so I'm editing genes, working with microorganisms, and even expressing proteins for the first time. The secondment at Dr. Schallmey's Lab is improving my Ph.D., and the skills I'm learning here will help me greatly in the future."
#7 - Tiago Cordeiro (ITQB-UNL, PT) secondment at ZYMVOL, ES (Nov 2019)

Ulises got new skills in molecular biology, enzyme engineering by rational approaches, and biochemical and kinetic analysis of enzyme variants.
Ulises's testimonial
"My social experience here in Groningen is as enriching as the academic one. Being a small city with a big university, Groningen has a very youthful vibe. Besides, there is plenty of people from all around the world, so everybody, even Dutch people, speaks perfect English. My current coworkers have been welcoming since the first day and have shown me how people have fun here. Friday and Saturday nights are great, full of restaurants, pubs, and bars of different kinds. People here are very easygoing and making friends and having a good time is easy. But not only nights are interesting in Groningen. The city is beautiful and has many nice details and cultural attractions, like historical places and museums. Moreover, it is surrounded by nice little towns and beautiful landscapes of different types. Cycling for several hours and discovering all those places have been a lovely way to spend some weekends, despite the bad weather. Last but not least, very interesting cities such as Amsterdam or Rotterdam are a few hours by train from here, and I took advantage of that also by visiting them during some weekends."

Emanuele's testimonial
"All the objectives have been completed. I disseminated our work at three distinct events, reinforced ties with Fraaje’s group, and networked with academic and industrial representatives. The interaction with outstanding computational enzyme design community members during the masterclass was especially a unique opportunity for growth for the company and me as a scientist. The lecture propelled a proficuous Q&A session, mainly focused on detecting functional mutations that reside far away from the active site (which is part of our ongoing research). I had the pleasure of meeting outstanding scientists in the field: Jiri Damborsky and David Bednar from Loschmidt laboratories in Brno; Marc van der Kaamp from Bristol University; Dick Janssen and Hein Wijma from Groningen. I had the chance to learn about their current research, and the hand on sessions were extremely valuable to get more proficient with computational tools that are very interesting for our company research."
#2 - Dimitris Argyropoulos (NCSA, USA) secondment at Ca' Foscari University of Venice, UNIVE, IT (Jul 2019)

She has supported outreach events such as the European Researcher’s Night 2019 and ITQB Open Day.
.
Magalí's testimonial
"This 6-month experience has been, without a doubt, the most challenging one in my life. I’d just finished my bachelor’s degree, and in just one month, I found myself starting my Ph.D. in Lisbon, Portugal. I was out of my comfort zone: away from my family, my friends, my language, and even my field of knowledge, since I am a chemist and most of the work I started doing in Dr. Lígia Martins’ lab was in the field of microbiology, biochemistry and molecular biology. I was also living alone for the first time! The amazing thing about all these “obstacles” is that when you get to the finish line, you can look back and be extremely happy about your results. This secondment improved my scientific knowledge (for sure), but it also taught me a lot about life. None of these things could have been possible without the guidance and help from Lígia: thank you! The people from the lab were always there for me, helping me with the benchwork, answering questions, and even taking me out to discover Lisbon. So, I can say that I learned new techniques, new ways of thinking, I got to live in a beautiful city full of life, and I even made an amazing friend (Francisco) who I think will remain for life."
