CV synopsis

Following the usual geeky childhood events of extracurricular math and science activities, getting my first computer at age 6-7 (an Atari 800XL), and teaching myself to program in Basic, and later in Pascal and x86 assembler, I moved to study Math and Physics at the university in a program for such similarly gifted geeks. After graduation, I worked several years in the aerospace industry in system engineering, before embarking on my academic endeavors in biology.

I did a PhD in Ecology and Evolutionary Biology applying mathematical models to studying problems of population dynamics and species geographic distributions. For my PhD studies I won a four-year fellowship. After completing my doctorate I worked as a postdoctoral researcher, doing research on life-history theory and evolution of life-cycles and developmental trajectories. Following that, I got a position as a lecturer (assistant professor), in which I remained for two more years. During that time I applied for and won a four-year research grant.

During the years of my study and professional occupation, I have gained many and varied skills and much experience in research, analytical and statistical techniques, programming, scientific computing, scientific communication and teaching. The sections below provide a more detailed view.
