Ranmal Aloka Samarasinghe is an assistant professor at the University of California, Los Angeles (UCLA). He received his M.D. and Ph.D. from the University of Pittsburgh in 2013. He performed his thesis research in the laboratory of Donald DeFranco, where he studied nongenomic actions of glucocorticoid hormones in neural progenitor cells.
Samarasinghe completed his residency in adult neurology at UCLA in 2017 followed by postdoctoral research and clinical fellowship at UCLA in 2020. During his fellowship, Samarasinghe obtained clinical training in epilepsy and neurophysiologic intraoperative monitoring. His postdoctoral work with Bennett Novitch has been on human stem cell derived 3-D in vitro brain-like structures called ‘brain organoids.’ He has focused on developing multimodality approaches including two-photon imaging and extracellular electrode-based techniques to understand the mechanisms of brain organoid neural network formation and function.
