Research

One emphasis of past research has been in biophysical studies of nucleic acids and of single-stranded DNA-binding proteins, such as the gene 5 protein of Ff bacterial viruses and the human replication protein A. Another emphasis has been to relate the nearest-neighbor, and next-nearest-neighbor, properties of DNA oligomers to the effectiveness of antisense DNA control of cellular gene expression.
