We are very pleased to announce that there is a new Doctor in the house! Boris Leistedt passed his PhD viva titled “Accurate Cosmology with Galaxy and Quasar Surveys” with flying colours. We also celebrate Boris’s success in the recent postdoctoral job season: having received offers of several prestigious fellowships in the USA and Europe, Boris has decided to take up a Simons Fellowship at New York University to continue his highly innovative work in survey cosmology. Congratulations and best wishes to Dr. Leistedt!
