A brilliant and enigmatic scientist, Dr. Katherine E.A. Korkidis, known simply as Dr. K, is the guide and mentor for Jennifer and Daniel on their time-traveling adventures. With a deep knowledge of physics and chemistry, she introduces the children to various scientific concepts and historical figures, making complex ideas accessible and exciting. Dr. K possesses a unique ability to connect with young minds, explaining the wonders of the universe in a way that sparks curiosity and inspires learning. Though her background remains somewhat mysterious, her passion for discovery and teaching shines through every adventure she shares with Jennifer and Daniel.

At 10 years old, Jennifer is curious, adventurous, and always eager to learn. She has a natural fascination with the stars and a keen interest in science, which draws her into Dr. K's world of time travel. Jennifer often takes the lead in asking questions and diving into new experiences. Her inquisitive nature and determination make her an ideal companion for these journeys, as she tries to make sense of the complex scientific ideas presented to her. Throughout the story, Jennifer’s character shows a blend of wonder and a growing confidence in her ability to grasp challenging concepts.

Daniel, the 8-year-old younger brother of Jennifer, is lively, imaginative, and always ready for an adventure. While he may not always understand the scientific details as quickly as his older sister, his boundless enthusiasm and creative thinking bring a unique perspective to their journeys. Daniel often surprises the others with his unexpected insights and humorous observations, adding a lightheartedness to the story. He is brave, sometimes impulsive, and highly adaptable, qualities that help him keep up with the fast-paced and often unexpected nature of time travel.

Dr. Liu is Jennifer and Daniel's grandfather, a retired engineer who lives with them. Although he does not know about Dr. K or the time portal, he plays a crucial role in sparking the children's curiosity about science. Dr. Liu often shares stories from his engineering days and explains scientific concepts in a way that is both practical and accessible to his grandchildren. His interactions with Jennifer and Daniel are filled with warmth, wisdom, and encouragement, setting the foundation for their fascination with the world around them. He serves as a bridge between the children's everyday lives and the extraordinary adventures they embark upon with Dr. K.

My full name is Dr. Katherine E.A. Korkidis, but over the years, my students have affectionately come to call me Dr. K. My journey began in industry, where I conducted original research after completing my graduate degree in physics and chemistry. Alongside my research, I taught at several universities and developed groundbreaking technologies, all while exploring the world, from the United States and Canada to Europe, Russia, and the Far East. These experiences enriched my perspective and allowed me to combine my love for teaching and writing. Eventually, I realized that storytelling was my true passion, and I transitioned into writing full-time. My first novel, Josette, marked the beginning of this exciting new chapter.

Since then, I have authored nine award-winning books, each exploring a variety of themes and genres. Among my proudest achievements is The KEAK Anthology, a collection of short stories spanning multiple genres. This work earned 14 Gold Book Awards between late 2023 and the end of 2024, a testament to its appeal across diverse audiences. In 2024, I ventured into the world of children’s literature with the publication of my first chapter book for readers aged 8-12. This new series, Dr. K’s Portal Through Time, combines history, science, and adventure to ignite curiosity and inspire young minds. The debut book, Galileo’s Points of Light in the Night Sky, takes readers on an unforgettable journey through time to 1631 to meet Galileo, blending real science with the magic of storytelling.
I am honored to share my stories with readers of all ages and hope they inspire imagination, curiosity, and a lifelong love for learning.

Her ability to translate complex scientific concepts and historical events into engaging visuals makes the Dr. K's Portal Through Time series even more appealing to the young audience. Nunez's work complements Dr. K's narrative, making the series a must-read for children with a keen interest in science, history, and adventure.
