Mehr Fatima
I am Mehr Fatima and I come from Pakistan. As far back as I can remember I have been a science and technology enthusiast. I took subjects such as Mathematics and Physics at a very early stage in life and was boggled by the vastness of knowledge I could charter in these subjects. After attaining first class throughout my secondary and higher secondary education, I chose Ghulam Ishaq Khan Institute (GIKI) – one of the top engineering universities in Pakistan for undergraduate studies in electronics engineering. In order to remain abreast with the latest research work in the field of electronics and broaden my horizon, I became an active member of IEEE International during my undergraduate period. This is where I got my first exposure to the field of Photonics and optical physics and I realized that this was something I wanted to pursue. I served as Vice Chair for Women in Engineering (WIE) – IEEE GIKI Branch). My bachelor’s final year project was “Laser based Computerized PCB (Printed Circuit Board) machine."
Right after my graduation, I started working as a Management Trainee in National Foods. After seven months, I switched my job to Pakistan Telecommunication Limited and worked as an ‘Assistant Manager’. I worked in the optical telecommunication department, which further motivated me to get a degree in photonics and optical telecommunications. I looked into the masters courses being offered in Europe and the one at University of Eastern Finland attracted me the most.
Currently, I am a master’s degree student in photonics at UEF. UEF is located in Joensuu, which is a calm and peaceful student city with very friendly people. The degree at UEF is a right balance of theoretical learning and experimental work. The next big question for me during my degree was which subfield of photonics I wanted to work in. The answer lied in my first lab work - designing, fabrication and characterization of a dispersive spectrometer (in the visible and NIR range). After the completion of my first year, I decided to go for an internship and by that time, I was sure that it had to be in spectroscopy. I applied in the ultrafast optics and X-Ray division at Deutsches Elektronen-Synchrotron – DESY and got selected for a project named ‘Construction of Fourier Transform Infrared (FTIR) spectrometer for the characterization of home-built laser’.
After completing my summer internship and course work, I started working as a master thesis student at National Metrology Institute of Finland VTT MIKES on ‘Radiocarbon detection using photoacoustic spectroscopy’ in the isotope spectroscopy group. In the future, I would work as a research scientist at VTT and continue my research work in the field of laser spectroscopy. Undoubtedly, the field of photonics has numerous areas of research that can bring revolution. I, for sure want to be a part of it.
Matias Koivurova
My name is Matias Koivurova, and I am a Finnish early stage researcher. My research concerns the properties of light; how to produce and measure different types of light, and what can be done with them. I am particularly interested in pulsed light, which is the main focus of my PhD thesis. The reason why I find this topic so interesting is that by engineering the properties of light, it is possible to produce a wide range of exotic effects: we can make beams that split or focus on their own, devices that are able to capture images without lenses, and even pulses that exceed the energy density of the suns core!
I originally came to UEF to study physics at the Bachelor level, because I didn't know what else I should do. I had no idea what I wanted to do in life, and physics seemed like a good temporary solution, from where I could transfer to something else easily. But the studies proved to be much more interesting than I expected, and I was swept away by physics and math. One thing led to another, and now I am finishing my PhD, which I never could have anticipated in the beginning of my studies. After defending my thesis, the next step for me will be to get a postdoc position.
Henri Partanen
I am Henri Partanen, a postdoctoral researcher in the Institute of Photonics in University of Eastern Finland. I come from Kitee, which is a small city just next to Joensuu. I did my Bachelor's, Master's and doctoral degree in University of Eastern Finland. I have continued my research work here, because - why to move too far from one's hometown. I am doing research on coherence properties of light, in particular, on measurements and modelling of the phenomenon. In this way, also the light sources used in the industry can be understood and simulated. Moreover, I have been working with 3D printing and its applications in optics.
Henri Pesonen
Hello! My name is Henri Pesonen and I have always lived in North-Karelia. After some young-years-adventures, I finished my master program in photonics in 2017 and in addition I did masters studies in mathematics also. I'm theoretically oriented and my passion is mix physics and mathematics which usually ends up beautiful pictures.
At the moment I am studying temporal coherence in resonance structures and resulting articles will be a part of my Phd. thesis. In the future I hope to extend temporal coherence of linear material-light -interaction to cover also non-linear materials. In UEF Joensuu one of the best features is to have tight and friendly working community; if I don't understand something, which actually may sometimes happen, I can always go and ask from the Professors. As another good thing I could mention the quality of the research done in our faculty: although being a small University we have spearhead-research of our branch of science done daily in our faculty.
Sampson Saj Andoh
I am Sampson Saj Andoh, a Ghanaian born young scientist. Currently I am an Early Stage Researcher with the Institute of Photonics. I hold a Bachelor of Science degree in Physics (specialization- medical Physics) from the Kwame Nkrumah University of Science and Technology in Kumasi Ghana and Master of Science degree in Physics (Photonics) from the University of Eastern Finland. After my early introduction to optics and photonics in my Senior High School and undergraduate studies, I became fascinated with the enormous potential it possesses. I developed a strong interest in photonics and its potential. This drove me to apply for and accept a position as a master student in photonics in the University of Eastern Finland. My masterwork introduced me various aspects of optics and photonics; from the very basic to expert applications of these.
Now I am in my final stages of my doctoral studies that seeks to develop a simple but effective and efficient optical tool in detecting adulteration in edible oils. Edible oil is a basic component of a well-balanced meal; however, edible oils have become viable for economically enhanced adulteration. Adulteration in edible oil take the form of dilution (such as addition of inferior oil to premium ones), addition of authorized additives (such as enhancing the hue of olive oil with copper chlorophyll), and many others. This tool would also have the potential for forensic and analytical detection in other liquids such as blood, urine, wines and beverages.
Finland and University of Eastern Finland have given me a wonderful opportunity, serene and cordial atmosphere to develop as a young Scientist. With it’s greenly environments, wonderful place in raising a family, and open-mindedness I love living in Finland. I am working very hard that after my doctoral studies, I get to continue to post-doctoral level in UEF or other University.

Ibrahim Issah
The world we live in is a global village. Every human being has the potential to enhance the perception of another in the pursuit of global peace and prosperity. We should all approach life as neither half full nor half empty, but rather as the very visible fact that the glass is right side up and hence there is always the potential to absorb new ideas and perspectives; to listen and to understand where other people are coming from. This way of looking at life has shaped my growth, my community’s growth and the conversations I have every day as a student of life with an insatiable thirst for knowledge of the myriad ideas of our world.
Ibrahim Issah is an adaptable Biomedical Engineering graduate from University of Ghana and an addict to computer programming who is currently doing his master's degree program at University of Eastern Finland (UEF). I seek intellectual engagement and yearn for the development in leadership, cultural and health intelligence. With some research and publications in pharmacokinetics, spectroscopy and biological computational modelling, I developed the interest to link photonics to biomedical engineering; thereby, furthering my academic career in Photonics.
The correlation between photonics and biomedical engineering is perspicuous relative to devices in the medical field. In addition, these photonics technologies are crucial considering non-invasive clinical monitoring, medical imaging as well as molecular diagnostics.
The esteemed and effective staff of UEF and their unflinching support in my academic career has provided me with the opportunity to attain my ambition; thus, to correlate biomedical engineering with photonics (Bio-Photonics) to help utilize photonics technologies to solve medical problems. My stay in Finland has been exquisite and its microcosm of multiculturalism is vivid in every sense of the word. I am privileged and honored to sit in the same class with people who have different dreams, fears and stands about some of our global problems.
UEF photonics has introduced me to various aspects of optics and photonics and hope to apply these techniques to solve medical problems in future.

Dura Shahwar
I am Dura Shahwar and currently doing MSc. Photonics from university of eastern Finland. Initially, when I was asked to talk about my journey till here, I was pretty confused because it felt like a responsibility as perceptually your journey would have to be worth sharing and I feel like having a long way to go to be that successful. In anyways, I was born and brought up in my native town Chakwal, Pakistan, blessed with a healthy family comprising of the supportive parents and siblings. Growing up with my siblings and the couple of friends I had at that time, who helped me to grow as a person; I crossed the borderline of my college life. Being highly interested in science and technology since quite a good time, I felt no difficulty in recognizing the Electronics Engineering as the degree, which perfectly triggered my interests. I got into the University of Engineering and Technology, Taxila, Pakistan and started my life full of experiences. I made quite a feat when it comes to my academic performance. I served the International Electrical and Electronics Engineering (IEEE), CES Chapter as the general secretary where I got a chance to build my professional as well as personal expertise Besides the academic, I have experienced to work with two firms as “National Development Complex [National Engineering and Scientific Commission]” and ‘’Bestway Cement Limited’’.
Subjects related to electromagnetic fields, optoelectronics, and internships experience in fiber optics and optoelectronic sensors, triggered my interest to study more about photonics and its combination with electronics circuits. My desire to learn Photonics and experience a different culture and a different study environment altogether encouraged me to apply to the foreign universities. Because I know that, nothing can be achieved without stepping out of the box.
MSc. Photonics program at University of Eastern Finland attracted me more because of diverse combination of courses and lab works offered. Because of this degree program, I got opportunity to work with VTT technical research Centre of Finland, a well-known research institute. I am now doing my Master thesis research work in Silicon photonics at VTT, which emerged as the replacement technology for electronic circuits. This research work helped me to explore polarization state of light and its applications in telecommunication for broadband operations. Further, I learned some free-form optics concepts in silicon photonics based integrated circuits.
As far my experience with Finnish people and culture is concerned, I feel lucky to live in such a peaceful and organized culture. Finnish people are very collaborative and helping in every matter. I have made many memories and friends from different nationalities during my stay. I would prefer to continue my research work in Finland.
In future, I would like to pursue my career as a researcher in silicon photonics especially in designing and fabrication of ultra-miniaturized and compact integrated photonic devices.
Prince Bawuah
Dr Bawuah graduated from the Master’s Degree Program in Photonics in May 2013, continued with his PhD studies in August 2013 and completed in January 2017 at the Department (Physics and Mathematics), University of Eastern Finland. With over ten peer-reviewed publications during his doctoral studies, in conjunction with the high level of competency proven during his public defense, Prince’s doctoral dissertation was approved with Distinction.
According to him, all these great achievements wouldn’t have been possible without the funding/scholarship, cutting-edge scientific facilities, experienced and hardworking staff provided by the Institute of Photonics, University of Eastern Finland.
“I am grateful to say that the tremendous experience gained through the numerous international conferences and collaborations, summer schools, and short research visits to top Universities during my studies, which were fully sponsored by the Department of Physics and Mathematics, have significantly contributed to where I am today. I was very lucky to work with Emeritus Professor Kai-Erik Peiponen, an excellent and highly experienced supervisor, who did not just act as a supervisor but also played a fatherly role in guiding me during my studies. I always remember and bless the day I took a bold decision to move to Finland and to work with Prof Peiponen. This was indeed a life-changing decision. I will encourage upcoming scientists to love what they do. We should spend time on our research, sit down to read and deeply meditate on the “little” science we do. These little contributions to the knowledge of science will definitely lead us to higher grounds in our future endeavours” Prince opines.
Prince is currently a Research Associate at the University of Cambridge, working with the Terahertz Application Group (TAG) at the Department of Chemical Engineering and Biotechnology. Prince’s current research is mainly focused on the development of a rapid and non-destructive Terahertz-based test instrument for predicting pharmaceutical tablet efficacy and performance, based on direct porosity measurements. This is a direct continuation of his PhD studies at UEF (http://epublications.uef.fi/pub/urn_isbn_978-952-61-2311-0/urn_isbn_978-952-61-2311-0.pdf), where he developed the concept of terahertz-porosity. Prince’s current project partners include industrial giants like GlaxoSmithKline (GSK), Huxley Bertram and TeraView.
Cambridge seemed a natural choice for Prince, who is highly motivated to delve deep into the application of terahertz technology in tracking the quality of pharmaceuticals. “This is how having a solid foundation in Photonics can transform your life, from being a Physicist to a complete Pharmaceutical Scientist. Now, I call myself a Pharmaceutical Physicist” he says.
Dr Bawuah is a young Ghanaian scientist, who obtained his senior high school education at Tepa Senior High School and completed a bachelor in Science Education at the University of Education Winneba, Ghana. His inspiring career curves have been, in part, guided by hard work and sense of purpose. It is no accident that he has accomplished so much in such a short time (more than twenty peer reviewed articles; https://scholar.google.co.uk/citations?user=htTrQaEAAAAJ&hl=en, https://www.researchgate.net/profile/Prince_Bawuah).
Despite his relatively poor background, the Cambridge-based alumnus and the first African to enrol in the International Program in Photonics UEF, wishes to pass on to the next generation, especially young African Scientists, that with hard work and goal oriented spirit, the impossible becomes possible. “I give presentations at the various Universities in Ghana anytime I go back home. This gives me an opportunity to interact with students and offer some guidance. It is a passion and it always feels good to connect with students. Finally, I wish to stress that for a solid foundation in Photonics through quality training by hardworking staff coupled with ultramodern instruments, the best place to be is the Institute of Photonics, University of Eastern Finland, Joensuu Finland”.
Dr Bawuah wishes to express a heartfelt gratitude to both the teaching and the non-teaching staff (Noora, Katri, Hannele, Marita, Oili), colleague researchers, students and friends at Joensuu, and finally to his beautiful wife, Shirley Bawuah for all the support.
Marian Baah
My name is Marian Baah and a Ghanaian by nationality. I am now a Master degree holder and now currently working on my Doctor of Philosophy. My interest in Physics started during my senior high school studies and as I continued studying throughout my bachelor’s studies, I developed an interest in light and its interaction with matter.
Here at the University of Eastern Finland I am working at the Institute of Photonics in the cleanroom facilities. My research is geared towards the fabrication of graphitic carbon – waveguides. I started along this field of research during my Master’s degree program where I synthesized graphitic carbon films for characterization. After my Mater thesis, I decided to combine my graphitic thin films with waveguides and integrated optics. This field of photonics is the next-generation of Datacom and telecommunications, as it would aid the low power consumption for broad connectivity.
The University of Eastern Finland has afforded me the opportunity to follow my dreams of becoming a scientist. I have been exposed to the art of working independently and working with a wonderful team of scientists. Joensuu is a beautiful town and it has been lovely living here and Finland as a whole. This far, my stay and studies has been a pleasant journey. I hope that when I complete my Ph.D. thesis work I hope to give back to the Finnish society, by being given the opportunity to teach other up and scientists or help move the Finnish research and manufacturing industry to another level of expertise.
Sughra Mohamed
I am Sughra Mohamed from Bahrain. I am an early-stage researcher in photonics department, currently working on nanophotonics, nanostructures projects. I have done my master also in UEF, in Joensuu campus. I find my research subject interesting, unique, mind-blowing, as there is always something to learn, something to discuss, something to investigate and a room for development. Its a platform where things don't usually make sense start to be logical.
I am interested in photonics because its a way of seeing things from a different angle, it's like having invisible superpower glasses that let you see things more in depth.
I am studying light-matter interactions in plasmonic systems, I am experimenting with how the plasmonic signal can reveal a lot of information about nanostructures, especially in sensing applications.
During my time in Finland, I have made many great memories, great friends, and ate a lot of Finnish doughnuts. Also, being surrounded by smart people (students and teachers) is amazing. The education system in UEF/Finland is very efficient, and it pushes you to think outside the curriculum and help you to improve and perform your best in every step of the way. I have gained my confidence as a physicist from the knowledge and the experience I gain in UEF. The photonics department combines great scientists that have a lot of experience, and at the same time they are humble and always trying to help as much as they can with high-tech devices.
In the future, I would like to work in researchers combining different fields of photonics together especially light-matter interaction, nonlinear, fabrications, and nanostructures. Also, I hope to join the academic staff at the university in the future to teach the new brilliant minds and be able to share and give back some of my knowledge and experience.
Ségolène Pélisset
My name is Ségolène, I am French. I have started now my third year as a PhD student in Photonics, at the Department of Physics and Mathematics of the University of Eastern Finland.
In a previous life, I was an engineer in chemistry, working in a laboratory for Photovoltaics. I had been hired to study the materials used in solar panels. But after few years, I felt I was growing more and more interested in the magic behind the process of transforming sunlight into current and I realized that I wanted to know more about light. That is why I decided to study Photonics, first at master level and then as a PhD student.
I am now fabricating micro- and nano-structures that are interacting with light, just like electronic circuits are interacting with current. The field of Photonics is full of promises because of all the possibilities that have not yet been explored and all the applications that results from it. Nowadays, there are so many devices working thanks to Photonics, we don’t even realize it anymore!
I love being here in Finland. I enjoy life in this calm and green country, and I also appreciate the relationship with people. I think Finnish people are open-minded, frank and I have the sensation I can be myself.
This is why I am doing my best to stay here, in Joensuu, and if possible at UEF.
