2017 - Fellow of the American Mathematical Society For contributions to differential geometry, geometry of projective varieties, representation theory, and complexity theory.

- Algebra
- Mathematical analysis
- Geometry

His primary scientific interests are in Algebra, Combinatorics, Secant variety, Rank and Conjecture. His work on Projective geometry, Function field of an algebraic variety, Algebraic geometry and Birational geometry as part of general Algebra study is frequently linked to Rational normal curve, therefore connecting diverse disciplines of science. Joseph M. Landsberg works mostly in the field of Algebraic geometry, limiting it down to concerns involving Matrix multiplication and, occasionally, Multilinear algebra.

His Combinatorics research is multidisciplinary, incorporating elements of Hypersurface, Upper and lower bounds and Multiplication. Joseph M. Landsberg works mostly in the field of Secant variety, limiting it down to topics relating to Representation theory and, in certain cases, Vector bundle, Tensor rank and State, as a part of the same area of interest. His Rank research incorporates themes from Symmetric tensor and Polynomial.
