My first few semesters at Brown were a struggle, and I probably didn't deserve to continue on in the graduate program after receiving my master's degree. Carlé was very honest with me about the severity of the situation. I was fairly discouraged, but after some soul searching I realized I did not want to squander the very special opportunity I had as a graduate student in one of the best planetary science programs in the world. Over the next year, Carlé worked intensively with me to improve my
