In addition to rare diseases, she covers topics in endocrinology, infectious diseases, neurology, orthopedics, rehabilitation and wellness, hematology, oncology, gastroenterology, rheumatology, genomics, genetics, and precision medicine. Maria is a self-motivated, dependable, task-oriented, critical thinker. She is happiest when both her brain hemispheres work together—combining her analytical, logical mind with her creative, artistic mind.
