I'm a university student of theoretical physics and mathematics, whilst my own studies focus on gravitational physics (e.g. string theory), differential geometry, and gauge field theories.

• Advanced Differential Geometry: A Brief Introduction to Characteristic Classes from the Differential Viewpoint (Free Notes) by Yang Zhang, Cornell University
• Calabi-Yau Manifolds: A Bestiary for Physicists by T. Hubsch; an introduction to Calabi-Yau manifolds meant to be accessible to physicists, but requires a substantial background in some algebraic and differential geometry.
• Mannheim's Brane-Localized Gravity; discusses branes and fields in the context of general relativity, explicit computations are present throughout, in great detail.
• All volumes of A Comprehensive Introduction to Differential Geometry by Spivak; thorough, excellently written and with great insights.
