Research Interests

Blake is a theoretical and observational cosmologist. He has research interests across CMB and large-scale structure, with a particular focus on measurements of the gravitational lensing and scattering of the CMB.

Research Group

Blake leads the CosMicBacklight project, funded by a Consolidator Grant from the European Research Council (2026-). Group members and affiliates include:

Postdoctoral and senior researchers: 

Alex Lague

Jordan Krywonos

Ola Kusiak

Fiona McCarthy (now affiliated Royal Society University Research Fellow)

Niall MacCrann (now affiliated Royal Society University Research Fellow)

co-mentored postdocs (primarily IoA-based): Emilie Hertig, Bernardita Ried Guachalla

PhD students:

Irene Abril Cabezas

Carmen Embil-Villagra

Joseph Thornton

Guanming Liang

 

Former group members and next steps:

postdocs: Toshiya Namikawa (postdoc/SRA -> Project Associate Professor, IPMU), Louis Legrand (SNSF postdoc-> faculty, CBPF, Brazil), Giulio Fabbian (postdoc->Snr. Staff Scientist, CNRS), Boris Bolliet (postdoc/SRA -> Asst. Teaching Professor, Cambridge), Dongwon Han (postdoc -> tech. industry)

students: Gerrit Farren (PhD -> Chamberlain Fellow, LBNL), Frank Qu (PhD -> Hubble Fellow, Stanford), Omar Darwish (PhD -> postdoc U Geneva); Boryana Hadzhiyska (Masters -> PhD Harvard), Oliver Philcox (Masters -> PhD Princeton), Alex Reeves (Masters-> PhD ETH Zurich)

 

Blake's recent awards/honors also include an ERC Starting Grant (the CMBLENS project, 2020-2026) and the Royal Astronomical Society's Early Career Award (2019).
