I started in venture capital in the early 1990's, and became a GP at Oak in 2000. I now concentrate on health care and financial technology investments at Oak HC/FT. I blog, and I've published five books. I started programming computers in high school. Before graduating with honors from Harvard College, I wrote code for oil refinery optimization and the ARPA-net. I then wrote code for compilers, composition systems, operating systems, DBMS internals and applications, large scale financial transaction processing, document processing, workflow and more.
