Seminar on Computational Engineering

About us People Seminar

The Seminar on Computational Engineering at the LUT University is usually held in room 2411 on Tuesdays at 2pm. Our aim is to bring together computational science with applied mathematics and statistics.

From fall 2021 onward, the seminar will be organized in hybrid format: some of the talks will be held online via Zoom and some talks will take place on-site in Lappeenranta.
