MSRP taught me that science is best done in collaboration. I was excited to come in each day to learn from my lab mates, develop my own ideas, and find answers to the questions that kept us up at night. I worked on mammary gland biology and had a blast; it is so cool that organs like the mammary glands go through repeated cycles of growth and decay, and that I was able to grow one in a dish. MSRP truly taught me that few things can replace genuine excitement and hard work.
