Together with Cecile
Fradin, I am responsible for the Biophysics Specialization in the undergraduate
physics program. Students on this specialization take Core Courses in Physics
plus a range of courses from Biochemistry, Biology and Genetics. More

This text, aimed at upper
level undergraduates and graduate students, introduces readers to the twin
themes of Bioinformatics and Molecular Evolution.
Bioinformatics chapters
explain the need for computational methods in the current era of complete
genome sequences and high-throughput experiments, introduce the principal
biological databases, and discuss methods used to create them and search them.
Algorithms for sequence alignment, identification of conserved motifs in
protein families, and pattern recognition methods using Hidden Markov Models
and neural networks are discussed in detail. A full chapter on data analysis for
Microarrays and Proteomics is included.
Evolutionary chapters begin
with a brief introduction to population genetics and the study of sequence
variation within and between populations, and move on to the description of
evolution of DNA and protein sequences. Phylogenetic methods are covered in
detail, and examples are given of application of these methods to biological
questions. Factors influencing the evolution at the level of whole genomes are
also discussed, and methods for the comparison of gene content and gene order
between species are presented.
This book explains the
theories behind the methods of bioinformatics rather than the technical details
of how to use any particular software package. Important mathematical
derivations and statistical tests are explained at a level that should be
accessible to biological students with perseverance. Muliple-choice
‘self-tests’ are provided, with answers available on an accompanying web site.
A section of longer problems is also included. This text will help the next
generation of biologists and biochemists gain the confidence with quantitative
methods and the specific vocabulary they need to interact with the
statisticians, database analysts and software engineers they will encounter in
their future careers.

Several major breakthroughs
in the last decade have helped contribute to the emerging field of
Astrobiology. These have ranged from the study of micro-organisms that have
adapted to living in extreme environments on Earth, to the discovery of over
200 planets orbiting around other stars, and the ambitious programs for the
robotic exploration of Mars and other bodies in our solar system. This book
explores some of the most exciting and important problems in this field.
Beginning with how planetary systems are discovered, the text examines how
these systems formed, and how water and biomolecules necessary for life were
produced. It then focuses on how life may have originated and evolved on Earth.
The final section takes the reader on an exploration for life elsewhere in the
solar system, including Mars, Titan and Europa.
