As she shares, “Your lived experience is valuable and you don’t need a degree to become innovative.”

Her story reminds us that engineering is not only about equations; it is about creativity, problem-solving, and empowering the next generation.

Through workshops and community-led projects, she helps young people build, code, and create solutions that matter in their own communities.

As a young Black woman in engineering, she has faced stereotypes about who belongs in STEM. Her response has been to create space for others.

This interactive explores how surface area & volume shape cell size & why living systems rely on many small cells instead of a few large ones.
Surface Area and Cell Size
Cells are the basic units of life. Most animal and plant cells are, on average, 10 to 100 micrometers (μm) wide. A...

This animation follows a white blood cell as it moves through the bloodstream and reacts to external signals. Inside the cell, you can see organelles, cytoskeletal structures, and molecular “highways” working together, transporting materials, producing proteins, and changing shape in real time.

Learners investigate everything from membrane-bound compartments to energy-capturing structures, and compare eukaryotic and prokaryotic cells to see how form supports function. The focus is on seeing the cell as a system, where different components interact to maintain internal balance.
