Welcome to Virtual TSOP 2021 /hosted by Bulgaria/

Dear Colleagues and Friends,

With continuous restrictions regarding travel and hosting events by governments and health authorities the Organizing Committee of the 37th TSOP Annual Meeting has decided to transform it into a virtual event for the health and safety of our members and participants. Instead of getting together in Sofia, Bulgaria as planned, we will now be meeting online on September 12-14, 2021.

This is a great opportunity to find out together how we can experience the new world of online conferences. We are confident that the quality of the meeting will be as high as always, and the learning potentially even greater than usual. We really will be able to replicate almost everything we do at traditional meetings in this online space. It is very important TSOP meetings to keep providing an ideal academic platform for researchers to present the latest research findings and describe emerging technologies and directions in Organic Petrology.

We will strive to maximize opportunities to promote the social side of our conference for our participants.

We are really looking forward to welcoming you to explore the first online TSOP Annual Meeting in September 2021.


Prof. Irena Kostova
Chair of the Organizing Committee
