## Summer Mathematics Programme Tailored to Students’ Research Interests

The HSE Summer University is off to a strong start this year, and one of its programmes – the Research Experience for Undergraduates (REU) in Mathematics – has already been met with considerable enthusiasm by participating students. Designed for undergraduate students majoring in Mathematics or related areas, participants work on research projects under the supervision of distinguished mathematicians.

## Seminar on Teaching at HSE

On November, 22 International Faculty Support Unit has organized a peer-to peer workshop for international faculty members on teaching at HSE. The seminar enabled newcomers to get acquainted with specifics of the teaching process at HSE, and their more experienced colleagues had an opportunity to share their experience.

## Mathematics Professor Calls Moscow Home

Christopher Brav, Assistant Professor in the Faculty of Mathematics, joined the Higher School of Economics in 2014 after holding several teaching and research positions abroad. The HSE news service recently had the opportunity to speak with him about his research interests, teaching philosophy and how he has settled into life in Moscow.
