RESEARCH

Dr. Clifford Johnson's research interests are mainly concerned with the development of theoretical tools for the description of the basic fabric of Nature. He is part of the international effort to understand and describe the origin of, and the fundamental constituents (and their interactions) of the Universe. He works mainly on superstring theory, quantum gravity, gauge theory, and M-theory, studying objects such as black holes and D-branes, using a variety of techniques from Mathematics and Physics.

BOOKS

Clifford V. Johnson has a new book, ** D-branes**:
D-branes represent a key theoretical tool in the understanding
of strongly coupled superstring theory and M-theory. They have
led to many striking discoveries, including the precise microphysics
underlying the thermodynamic behaviour of certain black holes,
and remarkable holographic dualities between large-N gauge theories
and gravity. This book provides a self-contained introduction
to the technology of D-branes, presenting the recent developments
and ideas in a pedagogical manner. It is suitable for use as a
textbook in graduate courses on modern string theory and theoretical
particle physics, and will also be an indispensable reference
for seasoned practitioners. The introductory material is developed
by first starting with the main features of string theory needed
to get rapidly to grips with D-branes, uncovering further aspects
while actually working with D-branes. Many advanced applications
are covered, with discussions of open problems which could form
the basis for new avenues of research. See
