Biography and Education

Research Interests:

Hardeep Singh, PhD, studies retinoblastoma development. His research is focused on understanding how features of the cone cell of origin of retinoblastoma sensitize to RB loss and MYCN over-expression to enable cone precursor proliferation. He particularly aims to understand a human cone precursor proliferation related program as a step towards producing humanized mouse models that better mimic human cone and retinoblastoma biology.
