What is SRS?

SRS is a summer research school for high achieving teenagers with pronounced interests in the fields of mathematics, informatics (computer science) and ICT. It combines the best practices from leading programs for high school students in the field, such as RSI (organized by CEE and MIT), with the unique opportunities of a dynamic small-scale learning environment.

High School Student Institute of Mathematics and Informatics

High School Students Institute of Mathematics and Informatics (HSSIMI) identifies school students with inclination for doing research in mathematics and informatics and takes care for their development by organizing every year two conference-type contests (in January and April) and a Summer Research School (in August).

Who is eligible?

High school students aged 15 to 19 who have not yet completed their secondary education may apply for the program.

How to apply?

The online Application Form is now available and will be open until

  • April 30th, 2023.

Scientific aspects

The students will work with scientific mentors, traditionally stemming from the Bulgarian Academy of Sciences and guests from international research universities in the fields of mathematics and informatics.

Each student will focus on a personal research topic, coming from challenging but viable field such as Combinatorics, Number Theory, Algebra, Computing, Genetic Algorithms, Modeling and others.

The program includes lectures on advanced scientific problems and modern technologies, meetings with representatives of the industry and different academic institutions, soft skills training and discussions on important issues such as ethics in science, responsible research and innovation.


The SRS team is planning to have a hybrid school in 2023. Students (and their parents) should decide in advance how they will participate – online or face-to-face.

Currently, there are no Covid-related restrictions and requirements for entering Bulgaria but we cannot guarantee that this will be the case still in the end of July.

The first week (July 23 to July 30) will be held online for all participants. July 30th will be the arrival day for all students who have decided to continue their participation on site, in the city of Varna, at the Conference and Recreation Center of the Bulgarian Academy of Sciences (aka the Creativity House of BAS). International students will be expected to arrive at Varna Airport on July 30th and to depart on August 12th).

Program costs

The complete participation fee is EUR 1160. The fee covers accommodation, meals, tuition fees for the entire duration of the school. It does not cover travel expenses to and from Bulgaria, medical insurance, out-of-pocket expenses, accommodation for extra nights, etc.

The fee for online participation is EUR 400.


During its twenty years of existence, the High School Student Institute of Mathematics and Informatics (HSSIMI) has formed an extensive alumni network, with numerous young researchers and ICT professionals, currently studying and graduating from the highest ranking research universities (MIT, Princeton, Oxford, MGU, Harvard, etc.). Many of them now return in the capacity of mentors, continuing to support the mission of the institute and other internationally-recognized research programs, such as RSI, SRSI, PROMYS, and others.

  • 10 alumni ranked among the “Top 5” student researchers at RSI
  • 5 alumni with Intel ISEF awards in the last two years
  • 6 alumni with EUCYS awards in the last four years
  • ~15% of the participants accepted in the Ivy League, MIT and “Oxbridge”.
