Throughout his teens and early 20s Daniel thought he was a professional adventurer. He built two traditional wooden boats, one in Indonesia and another in Bangladesh, which resulted in a shipwreck in the Indian Ocean and rescue during the fall of 2002.

He has a love for languages (speaking English, Spanish and Bengali well) and grew up in a family that collected ethnographic art so he has a slightly above average understanding about material culture.

Someday he wishes to be referred to as the world’s leading expert on William James and John Dewey (at least by his wife). He loves playing basketball, swimming and he actually likes spending time with his wife and kids.
