I have been a post-doc in Drew Endy's lab at Stanford University since Nov 2010. The focus of my project is to redesign phage using both rational and combinatorial methods in order to finish the genetics of a simple system. In December 2012 we published the first report of a [http://www.ncbi.nlm.nih.gov/pubmed/23079106 fully decompressed genome], using the bacteriophage øX174 as a model.

My current work is focused on using øX174 to pioneer a new method of simplifying synthetic genomes, a process I call 'negative genomics'.
I started off my science career at the University of Alberta (Canada), working in the Casey and Michalak labs. Summer student work in the Casey Lab on the human sodium-bicarbonate co-transporter protein resulted in an authorship in a peer-reviewed publication. My honors project in the Michalak Lab had me determining the role of calcium signalling and calreticulin on murine embryonic stem cell differentiation. After achieving a B.Sc. (Honors) in Biochemistry in 2003 I went to the Beatty Lab at the University of British Columbia to start my Ph.D. While at UBC I discovered that a photosynthetic organism called ''Rhodobacter sphaeroides'' was capable of re-routing its chlorophyll biosynthetic machinery around a blockage to generate a new type of chlorophyll. November 2010 I was conferred a Ph.D in Microbiology and Immunology from UBC.

I have been a post-doc in Drew Endy's lab at Stanford University since Nov 2010. The focus of my project is to redesign phage using both rational and combinatorial methods in order to finish the genetics of a simple system. In December 2012 we published the first report of a fully decompressed genome, using the bacteriophage øX174 as a model. This virus has shared many other firsts in the world of genomics and synthetic biology from being the first DNA genome sequenced by Frederick Sanger to the subject of claims of creating life in a test tube by watchers of Arthur Kornberg and Craig Venter et al.

My current work is focused on using øX174 to pioneer a new method of simplifying synthetic genomes, a process I call 'negative genomics'.

I started off my science career at the University of Alberta (Canada), working in the Casey and Michalak labs. Summer student work in the Casey Lab on the human sodium-bicarbonate co-transporter protein resulted in an authorship in a peer-reviewed publication. My honors project in the Michalak Lab had me determining the role of calcium signalling and calreticulin on murine embryonic stem cell differentiation. After achieving a B.Sc. (Honors) in Biochemistry in 2003 I went to the Beatty Lab at the University of British Columbia to start my Ph.D. While at UBC I discovered that a photosynthetic organism called Rhodobacter sphaeroides was capable of re-routing its chlorophyll biosynthetic machinery around a blockage to generate a new type of chlorophyll. November 2010 I was conferred a Ph.D in Microbiology and Immunology from UBC.

My unsuccessful cover illustration submission for JBC paper. A novel Zn-bacteriochlorophyll pathway operates in a Mg-chelatase mutant of Rhodobacter sphaeroides. The bchD mutant cannot chelate Mg2+ into protoporphyrin IX, which instead, has both both Fe2+ (red sphere) and Zn2+ (green sphere) inserted by ferrochelatase. Zn-protoporphyrin IX joins the bacteriochlorophyll pathway and is converted to Zn-bacteriochlorophyll.
