SCELSE Summer Course and Happy Hour
SCELSE Summer Course students took a break from their busy schedule to visit the Asian Civilisations Museum, guided by
SCELSE researcher and museum docent Dr Irina Bessarab, and go on a cultural tour of the city. Our Happy Hour in July was held in
conjunction with a farewell gathering for SCELSE PhD graduate Harikrishnan Nair, who landed an industry position in Heidelberg,
Germany. In addition, the crowd was bolstered by Summer Course students who joined in the festivities, singing and dancing well
