Summary

I am a global recombineering consultant and developer of recombineering techniques; highly skilled in homologous recombination, design and creation of complex genetic constructs and genome modifications. Currently, I am developing a new technology for cloning that may soon lead to a marketable product. I am organized and dependable, successful at managing multiple priorities and multiple people with a positive attitude with a willingness to take on added responsibilities to meet team goals. In my current role I design, construct and produce viral vectors to deliver a variety of cargos including calcium indicators for neurobiological research, and Cas9/CRISPR reagents for in vivo genome engineering. Part of my time is used in developing novel ways to use viruses, primarily to genetically engineered somatic cells and the mouse germline. The goal is to develop simple and fast methods to enhance the integration of large DNA repair templates via homology-directed repair, thus facilitating efficient gene tagging, humanisation and gene therapy.
