Research interests:

I am broadly interest in string theories, QFT, dualities and their interplay with geometry. You can find my publications and preprints here.


In the last week it is not unlikely that I have worked on:


• All things Calabi-Yau, compact or not
  
• Exceptional Holonomy: G(2) and Spin(7)
  
• Hodge loci of Calabi-Yau fourfolds, possibly elliptically fibred ones
  

Teaching/lecture notes:

• Geometry of Mathematical Physics III Michaelmas Term 23/24 lecture notes (pdf) (html)
  
Epiphany Term 23/24 lecture notes (pdf) (html)

• Dynamical Systems III Epiphany lecture notes (pdf)
• String Theory MSc lecture notes (pdf)
• QFT II MSc lecture notes (pdf)
• I have supervised several MSc thesis in the last years, if you are interested in doing a project with me, just write me an email an we can discuss a topic.
  

Some recent Talks:

• Various Talks (from 2017-2023) given in meetings of the Simons Collaboration on Special Holonomy in Geometry, Analysis, and Physics
  
• 'The fate of higher form symmetries in string compactification, 2021, NBMPS 63
  
• 'String Vacua, Geometry, and Arithmetic', GADEPs Seminars 2021
  
• 'From F-theory to G2 manifolds', Physics and Geometry of F-theory 2018 held at IFT-Madrid, 2018.
  

Random things I would like to draw your attention to:

• My Birthday in Mathematics
  
• All you ever wanted to know about Calabi-Yau manifolds, but were afraid to ask: Max Kreuzer's CY page at TU Wien; CYTools
• Sage: free open-source mathematics software
• The Oxford mathematics Alphabet
