# Katrin Becker

Katrin Becker (born Gelsenkirchen, Germany, October 7, 1967) is a theoretical physicist and textbook author specializing in string theory. She is a professor of physics at Texas A&M University.

## Life and work

Becker earned her diploma under Werner Nahm at the University of Bonn where she also received her doctorate in 1994 with a dissertation titled, Strings, black holes and conformal field theory. She was a postdoctoral fellow at the Kavli Institute at the University of California, Santa Barbara (UCSB) and then a senior research fellow at California Institute of Technology (Caltech) with John Henry Schwarz. She became an assistant professor at the University of Utah before moving to Texas A&M University in 2005.
Becker deals with string theory, for example in the development of models that make predictions for the Standard Model and realize models of inflation in cosmology. She worked closely with her sister, physicist Melanie Becker (also a professor at Texas A&M), with whom she wrote a popular string theory textbook along with John Henry Schwarz.
A general description of Katrin Becker's physics research has been published:
   In our quest for the fundamental laws of nature, we are led to wonder how to construct a theory of quantum gravity, a theory that reconciles gravity with quantum physics. Prof. K. Becker works on string theory. This is a quantum theory that predicts gravitation instead of contradicting it and it could be the unified theory of nature. It is a fascinating and unique framework.
In 2003, she received a Alfred P. Sloan Foundation Research Fellowship, and in 2005, a Radcliffe Fellowship.
In 2017, she received the Bush Excellence Award for Faculty in International Research

## Personal life

Katrin Becker was born in Gelsenkirchen, Germany to Ingrid and Karl-Hans Becker on October 7, 1967. She grew up in Malaga, Spain, with her older sister Melanie Becker, and the two sisters were recruited to Texas A&M in 2005 as part of a faculty reinvestment program. Katrin survived her sister and collaborator Melanie who died in 2020 after a long fight with cancer.
