DANIELLA RYLANDER OTTOSSON, PhD
Principal Investigator
Daniella Rylander Ottosson holds an MSc in Biomedicine from Lund University, Sweden, with a specialization in neuroscience through exchange studies at the University of Toronto, Canada. She earned her PhD at Lund University under the supervision of Prof. Angela Cenci Nilsson, focusing on pharmacological interventions and animal models of Parkinson’s disease. Her thesis, defended in 2010, received the Prize for Best PhD Thesis from the Parkinson Foundation Sweden.
She completed her postdoctoral training at IRCCS Fondazione Santa Lucia in Rome, Italy, in the laboratory of Prof. Paolo Calabresi, where she studied how cell transplants could restore neural circuitry in models of Parkinson’s disease. This work was part of an EU-funded research network. In 2013, she returned to Lund to establish a specialized electrophysiology platform within Prof. Malin Parmar’s lab, where she led pioneering work on cell repair and neuronal reprogramming, supported by independently secured competitive research grants.
Since 2018, Dr. Rylander Ottosson has led her own experimental research group at Lund University, consisting of approximately 10 members. Her lab focuses on neuronal repair and disease modeling using stem cell and direct reprogramming strategies, targeting disorders associated with interneuron dysfunction such as schizophrenia, Alzheimer’s disease, and epilepsy. Her interdisciplinary approach integrates human neuron reprogramming with functional circuit integration in the living brain. In recognition of her innovative work, she was appointed a Wallenberg Academy Fellow in 2021, providing national long-term funding and support for her research.
Her laboratory is equipped with cutting-edge infrastructure for human stem cell culture, in vivo disease modeling, viral vector development, patch-clamp electrophysiology, and transcriptomic profiling. Dr. Rylander Ottosson also plays an active role in national strategic initiatives in neuroscience and stem cell research, serving in leadership roles, advisory capacities, and with teaching responsibilities at Lund University.
In 2025, she was awarded a STIAS Fellowship at the Stellenbosch Institute for Advanced Study, South Africa.
