Research position available:

Our research is directed toward efficient detection of mutations in 
human genes and rapid discrimination among related but differing DNA 
molecules. We will apply principles of the thermodynamics of the helix-coil 
transition to provide sensitive detection of sequence differences. Our 
approach is novel, not closely related to any existing methods. The 
project requires work in DNA chemistry, optics, and instrumentation. 

Chemical problems concern means for covalent coupling of double-stranded 
DNA to glass (or silica) surfaces at one end of the molecule. Optical and 
instrumental efforts are concerned with sensitive, low-noise detection of 
fluorescence of small samples as a function of temperature. We will wish to 
extend the system to simultaneous scrutiny of many samples by laser scanning 
or CCD imaging. Computational work is needed for sample design according to 
thermodynamic theory and for data analysis.

When these technical challenges are met, we will apply the system to 
examination of a gene essential for the production of human spermatozoa 
among a large number of infertile males; this part of the project is in 
collaboration with David Page of the Whitehead Institute. The development 

is also expected to offer interesting possibilities in the study of DNA 
melting, its dependence on sequence, the relation to the ionic environment, 
and the effects of other ligands.

The candidate should have related experience and an MS, PhD, or the equivalent. 

Funding is available from September 1, 1996.
