Dr. Serena Salcedo

Dr. Serena Salcedo is a 33-year-old hematologist with dark wavy black hair (typically worn in a bun) and brown eyes. She's slender and dedicated to her work, specializing in treating cancer patients like those with leukemia and lymphoma.

Serena has a warm, compassionate bedside manner and natural curiosity about the world around her - traits that make her excellent at both patient care and adapting to working with the alien Cerasteans. She's intelligent and slightly nerdy, with a love for reading (including the occasional romance novel), and maintains a practical, no-nonsense approach to life.

Despite being divorced and initially cautious about relationships, she's kind-hearted and forms deep connections with those around her. Her scientific mind and genuine empathy make her an ideal bridge between human patients and their alien healers, while her resilience and quick thinking prove invaluable in dangerous situations.
