Welcome to the web-site of the Fundamental Physics Theory group!

We are a newly forming group in the School of Physical Science and Technology (SPST) of ShanghaiTech University focusing on Theoretical High Energy physics. Currently we are 2 faculty members, 1 visiting faculty member, 4 postdoctoral researches and several master and bachelor students.

The main research directions are quantization of gravity, cosmology, scattering amplitudes, string theory and string field theory, black holes and gravitational-wave physics, quantum chromodynamics, color-kinematics duality in gauge theories, double copy construction for gravity theories, conformal field theory, AdS/CFT, and related topics.

Postdoctoral researchers


Hiren Kakkad
Hiren Kakkad's research interests are scattering amplitudes in gravity and QCD, focusing on their geometrical formulation in the twistor space; exploring the boundary-to-bound-state dictionary for gravitational binaries in the context of gravitational wave physics.

Rémy Larue
Rémy Larue's research revolves around the study of quantum anomalies and Effective Field Theories in curved spacetime, via functional methods. In particular, his interests are: Path Integral methods for chiral theories, gravitational anomalies, Weyl and conformal anomalies, finite temperature/density effects.

Oleg Melichev
Oleg Melichev's research interests are classical and quantum aspects of various modified gravity theories such that the renormalization group approach to quantum gravity and its applications to Metric-Affine and Infinite Derivative theories and in particular the heat kernel technique to perform computation of a quantum effective action in these theories.

Abhishek Naskar
Abhishek Naskar's research interests are various aspects of inflationary cosmology, such as non-Gaussian signatures of different models of inflation, curvaton scenarios, primordial magnetogenesis etc.
