About me

I am a versatile technologist with solid experience in web development and turning ideas into products. I have a strong affinity for products designed on principles and involving complex data.

Experience

Founder / CTO sci.pe, Los Angeles - New York City

since 2014

Designed the vision; architected, built, ran the product; and managed the team behind sci.pe. sci.pe re-invented the scholarly publishing platform and was the first company to help publishers and journals transition to web-first publishing.

The company was incubated by Mozilla webFWD and Techstars NYC and worked with major publishers and independent journals.

Education

Ph.D. thesis in Ecology and Evolution, Laboratory Ecology and Evolution (UMR 7625); Universite Pierre et Marie Curie, Ecole Normale Supérieure, Paris, France - Awarded with distinction and special mention from the examination board

20062009

My thesis focused on the melding of immunodynamics, epidemiology and evolutionary biology. I used a combination of mathematical and statistical approaches to understand the processes driving outbreak dynamics and the wide range of pathogen phylogenies observed at scales from individual host to populations. Developements focused on influenza, dengue and HIV.

Technologies:

  • Blackboard, pen & paper

Extracurricular

Founder Journal for the Planet

Founded Journal for the Planet to provide a medium that policy makers and global citizens can leverage to better understand and solve the environmental issues of our time.

Perpetual board pumping techniques, land paddling, surfing & kitesurfing

Perpetual board pumping techniques were invented centuries ago by Polynesian and Hawaiian surfers, and when I am not working, you can find me surfing, kitsurfing or exploring the art of using motions of the body to propel a skateboard for long distances without putting foot to ground, sometimes with the help of a rattan pole.
