I took many courses in the sciences including physics, biology, and chemistry in high school and college. I spent 4.5 yrs in college and another 5 yrs in graduate school. I really enjoyed all my schooling. I enjoyed a very good science program in high school. About fifteen years ago, I met the Director of the San Francisco Insect Zoo and thought I would like to do something similar.
Communication skills are very important.
Organizational and computer skills as well as analytical thought and basic biology knowledge are needed. Convincing people not to fear or kill the unappreciated animals in the desert. Do some volunteer work in the field you are interested in, to see if it really suits you. Be yourself and be honest. Be willing to learn new skills.
