Profile Information

What best describes you?
Student, Science enthusiast


I'm Alexander, a recent graduate of Boston University's biology program and aspiring astrobiologist.
I am currently a middle school science teacher outside of Providence Rhode Island on the east coast of the USA. I am also entrenched in an attempt to find a graduate program anywhere in the world in something akin to microbial biogeochemistry specifically with relevance to extremophiles.

I'm stoked that SAGANet exists as it seems a superb resource to connect people all over the world with similar interests in a subject whose enthusiasts are so scattered in space and discipline.

I hope my presence here will help me connect with enthusiasts and professionals in the field who could lend some wisdom or suggest possible avenues to pursue or even just share a passion for all things science.
