NAIST Division of Materials Science Holds 11th Mid-term Evaluation Symposium

The Mid-term Evaluation Symposium 2019 was held in NAIST, last Nov 26 and 27. It is an annual event where a large portion of Materials Science course students present their research in conference-style oral and poster sessions. Now on its 11th year, it is one of the biggest internal events in the MS Division.

Internship in Slovenian Summer

As NAIST stands by its mantra of “Outgrow Your Limits”, it continues to branch out and reach different parts of the world with research collaborations with many universities. With a new connection to Slovenia, I am very grateful to experience a three-month internship there.

Imagine walking along the promenade 5 minutes away from where you conduct research!

At the tip of Slovenian coastal border along the Adriatic Sea, lies the old city of Koper. At its heart is the University of Primorska, comprised of re-purposed structures like the city post office building and a government office built from the time when the area was still part of the Venetian empire. While the exterior is a testament to Koper’s rich history, the interior is keeping up with the technological state-of-the-art.

At the basement floor of the Faculty of Mathematics, Natural Sciences, and Information Technologies, are makerspace and experiment rooms of the HICUP Lab (Humans Interacting with Computers at University of Primorska Laboratory, for long). Lucky to be in a lab with the latest and coolest in tech, I got to try out among many: wood laser engraving machines (fun fact: Slovenia is 60% forest!), eye trackers, head mounted displays, optical tracking systems.

This HTC Vive headset is very cool because it has Tobii Eye Tracking inside it.
The red thing behind me is the laser engraving machine.

The lab is co-directed by Assistant Lecturers Matjaž Kljun and Klen Čopič Pucihar, who were visiting researchers at the Interactive Media Design (IMD) Laboratory in NAIST from two years earlier. Throughout our internship, they discussed research ideas with me and Title, who is also a PhD student in IMD Lab.

I worked on two projects during my stay. One was about comparing a printed blueprint versus a desktop application versus a virtual reality experience for architectural plans. The other one is a project-in-progress about gauging audience emotions based on on-screen cues for theater plays or movies.

I’m very happy to have been given this opportunity to reflect on my current research direction and receive advice and feedback from experts in the area. In both IMD Lab and HICUP Lab, augmented reality and English are the main languages spoken–so it was an easy transition. The HICUP lab is also a diverse group, having members from Mexico, Sri Lanka, and France!

I had my worries before going for this internship, but it was actually just very pleasant. A Slovenian summer next to the Adriatic Sea offered some windy days and less humid atmosphere than what I usually have. Students had access to discount cards for nearby restaurants. The usual meals that cost €8 (¥940 as of this writing) were reduced to €3 (¥352)–a whopping 60% discount! The campus and our accommodations were by the coastline, so the walks and commute were leisurely, while the sunset sky were something to watch out for daily.

… or if not sunsets, how about the glacial waters of Lake Bohinj, going from turquoise to teal?

At the end of the internship, I came back to NAIST with many great memories of summer, plus a cool collaborative project that I will continue working on with people from thousands of kilometers away.

NAIST Materials Science Study Abroad Program for Doctoral Students

The Division of Materials Science (DMS) of NAIST provides its students with excellent opportunities to experience research culture and practices outside Japan through the Study Abroad Program, more commonly referred to as a lab stay.

Doctoral students from the DMS are required to earn credits under the set of courses called Internationalization Subjects. Two of the most commonly taken subjects are the Practical English for Materials Science (UC Davis English Program) and the International Internship. Students who participate in the lab stay program earn two credits under the International Internship subject. Many students, however, opt to do both, first participating in the UC Davis English Program then proceeding with the lab stay. The latter functions as a training ground for new English communication skills acquired in the previous program.

In preparation for the lab stay program, a student can either choose to go to NAIST Academic Partners or look for another university, depending on the compatibility of one’s research topic with the hosting institute. NAIST has more than a hundred academic exchange agreements with foreign universities and research institutes spread over multiple countries.

Communication with a potential supervisor can be established by the laboratory supervisor (at NAIST) or the student himself. Through this, a potential research topic can be discussed and necessary arrangements such as invitation letter, hosting agreement, student housing, etc can be made. Visa application may be necessary depending on the student’s nationality and the country of destination. Moreover, scholars would be delighted to know that NAIST covers most of the major expenses, such as the airfare, visa-related fees, and an accommodation subsidy. A comprehensive overseas travel insurance is also provided by NAIST to ensure the safety of the students during the entire lab stay program.

Joensuu City Theater, located in the city center, was built in the National Romantic style of architecture that flourished in the Nordic countries in the late 19th century.

I spent my two-month lab stay at the Institute of Photonics, Department of Physics and Mathematics, University of Eastern Finland (UEF) in Joensuu, Finland. My host supervisor was Assoc. Prof. Matthieu Roussey, the team leader of the Integrated Optics Group. Under his guidance, I worked on an interesting topic: slot waveguide integration of Bloch surface wave platforms. It was a productive and enjoyable two-month stay within Prof. Roussey’s group.

The snow-covered path that I take to get to the UEF campus everyday!

Last year, two other students from my laboratory joined the lab stay program. Christian Mark Pelicano spent two months at the RWTH Aachen University in Germany while Keisuke Yano worked under the Department of Physics, University of Cagliari in Italy.

It snowed almost everyday in my two-month stay in Joensuu.
The temperature ranged from 0°C to -24°C.

Indeed, more and more students each year are opting to go on a lab stay because of the tremendous opportunities it opens. It can definitely further one’s research and allows one to build a network for collaborative research work. I was blessed to have an open-minded and optimistic host supervisor who saw my research visit in his group as a starting point for further collaboration between NAIST and UEF.

Helsinki Cathedral. Probably the most iconic landmark in Finland.

Apart from the research aspect, the lab stay program is also an amazing opportunity to explore another country. During my stay in Finland, I was able to visit Helsinki and other major cities and learn more about Finnish culture and history. Immersing in a new culture, meeting people with different beliefs and customs, and interacting with a totally different society is a rewarding and humanizing experience. As student-researchers, this allows us to see better the world that we are trying to improve with our individual research, whether it be in physics, chemistry, or engineering.

CICP 2016: Posters, presentations and workshop

NAIST students are encouraged to pursue their own research projects. One of the avenues that NAIST offers is the CICP (Creative and International Competitiveness Project), a 6-month program in which students assemble a team, apply with a proposal and independently manage research funds to realize their project. At the CICP workshop, students present their progress.
