9th Walden Symposium

9th Paul Walden Symposium on Organic chemistry (Walden 2015), was held in the beautiful city of Riga on May 21-22, 2015. Symposium was hosted by the Latvian Institute of Organic Synthesis and Riga Technical University. It took place at the Latvian Institute of Organic Synthesis (Aizkraukles iela 21, Big Conference Hall), which is situated in Teika region in a 20 min driving distance from the historical Riga’s Old Town.
The programme and format of Walden 2015 was composed of plenary lectures by a distinguished international speakers, and poster sessions for the students. For the second time two oral presentations were given by the best Latvian PhD students. The goal of this Conference was to bring together the scientists, scholars, and students from universities, research institutes, and industry from Baltic States. Very special invitation was to the students to represent their research and have a wonderful choice for speaking with all the plenary speakers.
