Carmelo Piazza

Executive Director / Educational Director

Carmelo Piazza, also known as Carmelo the Science Fellow, has been teaching science to Brooklyn children for almost two decades. He taught students ages 4 through 11 at PS 261 for 16 years, where he quickly realized the effectiveness of science in motivating kids to learn other key subjects. In 2005, he opened the Cosmic Cove in Cobble Hill in order to offer science-based programs of his own design. The popular science camps, after-school programs, birthday parties, and mini-camps–which have been featured in The New York Times twice–provide an entertaining and educational mix of hands-on instruction, green slime and lizards, and humor.

Carmelo holds a master’s degree in Elementary Science and Environmental Education from Brooklyn College, where he took an inspiring course in Science Methodology that opened his eyes to the importance of doing science when learning science. He also did graduate studies in speech language pathology at LIU. Carmelo’s the author of Crazy for Science with Carmelo the Science Fellow, a book of at-home experiments that promote scientific observation, exploration, and analysis for young children. He also hosts a popular series of YouTube experiments. He has 4 kids of his own, ranging in age from 15 to 1.

In 2013, Carmelo achieved his dream of opening a preschool where he can teach science on his own terms, one where little kids are considered little scientists. The first location of Brooklyn Preschool of Science opened in Cobble Hill; the Park Slope location opened 2 years later.

Karen Piazza

Educational Director

Karen Piazza, known as Mrs. Marshmallow around the school, is a certified New York State teacher with a lifelong passion for education. She taught at the Cosmic Cove since its inception in 2005, and helped develop its preschool program. She also ran its robust schedule of science-based summer camps, after-school programs, and birthday parties. Her devotion to early childhood education combined with Carmelo’s love of hands-on, inquiry-based science led to the creation of Brooklyn Preschool of Science. Karen and Carmelo are married and have 4 children. From being a parent to being a teacher, Karen is with a child every second of her day—and she wouldn’t have it any other way!

Nadia Alini

Admissions Coordinator / Preschool Administrator

Brooklyn-bred Nadia Alini began working with Carmelo in 2004 when she was just 16 years old. As one of the first counselors at the Cosmic Cove summer camps, she saw first-hand the positive impact hands-on science had on young children. Nadia went on to study speech pathology at Adelphi University; after graduation, she worked as an administrative assistant at Rivendell Preschool in Park Slope for 5 years. Nadia is thrilled to be working with Carmelo again at Brooklyn Preschool of Science.

Miranda DeMartin

Educational Director

Miranda began her love for teaching children as a swim instructor for preschoolers. From there, she started her education at City College and received her Bachelor’s Degree in Education. While she worked as a Kindergarten teacher in the Bronx, she worked on obtaining her Master’s Degree in Curriculum Development through the University at Albany. She also received her New York State Teacher’s Professional Certificate in Early Childhood Education.

Miranda joined our school in 2018 as a 2’s teacher for several years before becoming the Education Director. What she loves most about our school is “the wonder that we instill in young children to pursue their curiosity and become independent science thinkers while learning about the world around them. And not to mention our diverse animals in our classrooms!” As the Education Director of our Amity Street School, Miranda continues her passion for early childhood education by guiding our wonderful teachers and supporting our families. She still finds the time to interact with our little scientists each day.
