Treena Livingston Arinzeh

Treena Livingston Arinzeh (born 1970) is an American biomedical engineer and academic.

She is professor of biomedical engineering at Columbia University, joining in 2022. She was formerly a Distinguished Professor in Biomedical Engineering at the New Jersey Institute of Technology in Newark, New Jersey. She is known for her research on adult stem-cell therapy. Arinzeh takes part in the American Chemical Society's Project Seeds program, opening up her lab for high school students from economically disadvantaged backgrounds for summer internships.

Arinzeh was born in 1970 and raised in Cherry Hill, New Jersey. She became interested in science by conducting imaginary experiments in the kitchen with her mother, who was a home economics teacher. She was encouraged to pursue a STEM career by her high school physics teacher.

Arinzeh studied Mechanical Engineering at Rutgers University, receiving a B.S. in 1992. She earned a M.S.E. in biomedical engineering from Johns Hopkins University in 1994. She continued her graduate studies at the University of Pennsylvania, completing a PhD in Biomedical Engineering in 1999.

Arinzeh worked for Baltimore, Maryland-based Osiris Therapeutics as a product development engineer. In 2001, she returned to academia and started working at the New Jersey Institute of Technology (NJIT) in Newark, New Jersey, where she founded the first Tissue Engineering and Applied Biomaterials Laboratory at NJIT in the fall of 2001. She was at NJIT until 2022 as a Distinguished Professor of Biomedical Engineering. She joined Columbia University as a Professor in Biomedical Engineering in 2022. She has published over 60 journal articles, conference proceedings, and book chapters.

Her current research focuses on systematic studies of the effect of biomaterial properties on stem cell differentiation. She is known for discovering that mixing stem cells with scaffolding allows regeneration of bone growth and the repair of tissue damage.

She discovered that one person's stem cells could be implanted in another person without causing an adverse immune response. In 2018, she received an QED award to work on the recovery time and cost patients experience after bone grafting procedures.

She was nominated by the Governor of Connecticut to the Connecticut Stem Cell Research Advisory Committee.

She is a fellow of the American Institute for Medical and Biological Engineering (AIMBE) and the Biomedical Engineering Society (BMES).

She is currently a co-PI and the Director of Diversity of the NSF Science and Technology Center on Engineering Mechano-Biology, which is a multi-institutional center with the University of Pennsylvania and Washington University in St. Louis.

In addition, Arinzeh actively tries to increase representation of minority students in biomedical engineering by being a mentor as part of the Project Seeds program supported by the American Chemical Society. Every summer, she invites 40 to 50 teens from under-represented groups to her lab to learn about engineering and her research.

In 2018, Arinzeh was selected to be a Judge for Nature scientific journal's newly created Innovating Science Panel Award.
