Ella Zeldich, PhD

Assistant Professor, Boston University Chobanian & Avedisian School of Medicine

Biography

Dr. Ella Zeldich is an Assistant Professor of Anatomy and Neurobiology at the Chobanian and Avedisian School of Medicine. She obtained her Ph.D. (Physiology and Pharmacology) from Tel Aviv University in 2009. Her current studies aim to understand the mechanisms leading to intellectual deficits and Alzheimer’s disease in Down Syndrome. As a molecular neuroscientist, Dr. Zeldich investigates the mechanisms leading to intellectual deficits and Alzheimer’s disease in Down Syndrome. Her team uses induced pluripotent stem cells (iPSCs) derived from individuals with DS to generate cortical organoids and assembloids to mimic neurodevelopmental and neurodegenerative processes associated with trisomy 21. Dr. Zeldich utilizes cutting-edge technological approaches including CRISPR, single-cell multiome profiling, high-resolution imaging, and xenotransplantation of the organoids through a variety of collaborative studies.

There are several active projects in the lab including:
• Investigating the contribution of X-chromosome-linked genes to cellular phenotypes and AD-related pathology in Down Syndrome
• Defining epigenetic determinants in oligodendrocyte maturation in Down Syndrome.
• Developing strategies to assess activity of trisomic neurons using assembloids and xenotransplanted organoids.
