Personal history:
Dorothy A. Mozart was born on Luna where she spent most of her childhood. Her father worked in the terraforming/environmental control station of Luna and her mother served as head of the Starfleet Security field office in New Berlin.
Spending a lot of time together with her father, she was introduced to the technical aspects of terraforming and maintaining a suitable environment on Luna. Thus, on her first trip to Earth at the age of five, she was astounded by the variety and complexity of nature which she encountered for the first time. During the subsequent visits to Earth and other planets that interest in nature which had been sparked on that first visit continued to grow until she was determined to become a biologist at the age of eleven.
At first she didn't even consider joining Starfleet because she associated this only with desk-jobs like that of her mother. Although participating in the pre-academy program in high school, she did not enter Starfleet Academy, instead she continued her studies at the Universities in Oxford, Earth and Zeh'Ha, Brentalia.
During her studies of Xenobotanics she discovered that she was even more drawn towards exploration than simple research and finally joined Starfleet at the age of 23. During her time at the Academy, she continued her scientific studies and finished her doctoral thesis during her first assignment as Assistant Science Officer aboard the U.S.S. Pythagoras.
During her time as Science Advisor and First Officer of the Scientific Outpost 604 (formerly known as Starbase 604) she continued and expanded her research concerning her doctoral theses - the studies of plant/animal hybrids, the artificial creation as well as the natural occurrence of the aforementioned.

Note: Captain Mozart is believed to be one of the last known decendants of the famous 18th century composer bearing that same name. However, she completely lacks any musical ability...

Personality:
Captain Mozart can be very stubborn and persistent if she decides to. She has proven to be a good commanding officer, often pressing her crew to go until their very limits, but never beyond them. However, she seems to lack the ability to realize her own limits, often straining herself way beyond what she can endure.
She can often be seen talking to her plants, which - however - should not be treated as an issue for concern. It is rather part of her widely recognized scientific studies.
