“Follow your bliss and the universe will open doors for you where there were only walls,” wrote Joseph Campbell, the American mythologist.

I’ve been a professional astronomer for more than 30 years, and feel fortunate to be able to explore the universe for a living. I got my PhD in astronomy from Yale University in 1987, and have held research, teaching and leadership positions around the world since then. 

One of the things I’m proudest of is my willingness to take risks and to follow my bliss wherever it leads. I’ve lived on four continents, learned several languages, and given up tenured professorships at two universities, all in pursuit of my dreams. 

Life is short, and in the end we're the sum of our experiences. Carpe diem!
