Chapter activities

1. Organization of international student conference

One of the main chapter activities was the organization of 8th

International Young Scientist

conference “Developments in Optics and Communications 2012” (DOC 2012) during April 12 –

14, 2012 in Riga, Latvia. More than 60 participants from 2 countries participated. The book of

abstracts can be found here http://docriga.lv/doc/history .

Student chapter meeting between Latvian and Lithuanian SPIE student chapters was organized

during DOC2012, increasing the collaboration between both chapters. Two chapter members of

Vilnius University Chapter – Vytenis Pranculis and Domantas Peckus – attended the conference

and the meeting.

During the conference, a Welcome party was organized. During the Welcome party, KHET Laser

game and table football were organized.

2. Organization of School for Young Physicists of Latvia

Several chapter members participated in organizing the School for Young Physicists of Latvia.

Once a month during the whole school year, school children from all over Latvia can come to Riga

and learn about different fields of physics by interesting lectures and laboratory work, including the

fields of optics.

3. “Science Night 2012”

On September 28, 2012, several members at different scientific institutes in Latvia participated in

the “Science Night 2012”, presenting interesting experiments to the public. This year’s theme was

energy.

4. SPIE Leadership meeting at “SPIE Optics & Photonics 2012”

Inga Saknite received the Officer Travel grant and participated in the SPIE Leadership meeting at

“SPIE Optics & Photonics 2012”. She made new collaborations with other chapter officers,

presented University of Latvia SPIE student chapter poster at Chapter Poster Session, as well as

participated in the Optics Outreach Olympics. She also did an oral presentation at the conference on

her Master thesis research.

5. 62nd

Meeting of Nobel Laureates in Lindau

President of the chapter Dainis Jakovels participated at the 62nd

Meeting of Nobel Laureates in

Lindau, Germany, which is a yearly event where only a selected amount of students and young

researchers are invited to meet and listen to presentations of 25 Nobel Laureates, as well as make

new collaborations and get new ideas for their research. This year’s topic was Physics.

6. Summer school in Portugal

Ieva Timrote participated in the 1st International Summer School on Advances in Ophthalmic

Optics and Optometry in Aveiro, Portugal, which was organized during September 14-16, 2012.

7. Prof. Francesco Pavone visit to Latvia

During December 5-7, professor Francesco Pavone of European Laboratory for Non-Linear

Spectroscopy in Florence, Italy, visited Latvia to give two presentations on his research on neural

optical imaging. His visit was possible thanks to SPIE Visiting lecturer grant. In total,

approximately 60 students and researchers attended both presentations. One of his presentations

was also filmed and later available on University of Latvia Youtube channel -

http://www.youtube.com/watch?v=eEdtOxQ__ck .

Grants and awards

20 members received European Social Fund scholarship.

Inga Saknite received Officer Travel grant to attend “SPIE Optics & Photonics 2013” in San Diego,

USA.

Eriks Zaharans and Janis Zaharans received scholarship to study at Linköping University in Sweden

as ERASMUS exchange students.
