Shinde DN, Goodman D, Tavaré S, Arnheim N. 2009. Product length,
dye choice, and detection chemistry in the bead-emulsion
amplification of millions of single DNA molecules in parallel.
Analytical Chemistry 81(14): 5770-6
This
paper is about an ultimate high-throughput single molecule PCR
method developed during my post-doctoral stay at the University
of Southern California and the Johannes Kepler University. With
this technology millions of single DNA molecules can be
amplified in parallel on microscopic beads. It has been a
turning point for my previously used technical approaches and
has opened several other venues of research.

2006. High resolution recombination patterns in a region of
human chromosome 21 measured by sperm typing. PLoS Genetics
2(5):e70.
In
this work, we studied recombination hotspots and carried out a
systematic survey of crossover rates using sperm typing during
my post-doctoral stay at the University of Southern California.
I developed a very efficient way of counting crossovers using
real-time PCR that allowed me to count recombinants in millions
of meioses. This work presented an important comparison of
population genetics and sperm typing approaches and provided
evidence about the possible co-regulation of hotspots of
recombination. During that research, I stumbled across the
intriguing properties of recombination hotspots.

observed human sperm mutation frequency cannot explain the
achondroplasia paternal age effect. PNAS 99: 14952-14957
This work on the paternal age
effect was the first to accurately quantify new mutations in
human sperm DNA, in the exciting and unconventional work on
achondroplasia. It required the development of a very sensitive
method that detected a single nucleotide change in a large pool
of wild type genomes. It addressed the long discussed topic
whether older men have a higher risk of transmitting new
mutations. This study was the first to experimentally measure
the mutational load on male germcells and pointed to the novel
observation of selection at the level of germcells.
