DANIELLA RYLANDER OTTOSSON, PhD

Principal Investigator

Daniella has a Master's in Biomedicine from Lund University with exchange studies at the University of Toronto where she specialized in neuroscience. She did her Ph.D. education at Lund University with Prof. A Cenci Nilsson, focusing on behavioral pharmacology and motor complications of Parkinson’s disease. Daniella defended her Ph.D. thesis in 2010 and was awarded Prize for best Ph.D. thesis from Parkinson Foundation, Sweden.

Her first postdoc was located at IRCCS Fondazione Santa Lucia in Rome in the laboratory of Prof. P. Calabresi, where she investigated synaptic plasticity after cell transplantation in Parkinson’s disease (F7 REPLACES EU network) supported by Tegger post-doc scholarship. In 2013 she was recruited back to Lund to establish an electrophysiology platform in the field of cell reprogramming as part of Prof. M. Parmar’s group. Here she led projects on in vivo neuronal reprogramming with support from SSMF (Swedish Society for Medical Research) and Parkinson's Research Foundation.

In 2017, Daniella was awarded an Establishment grant from Swedish Research Council and has since then been leading her own research group (appointed as Associate Senior Lecturer) with a focus on direct reprogramming and GABAergic interneurons both in situ in the living mouse brain, and in in vitro using human somatic cells. For these projects, she has been awarded the Jeansson prize in Sweden (2019).

 

In 2021, Daniella was appointed as a Wallenberg Academy Fellow, which is a career program established by Knut and Alice Wallenberg Foundation.

EFRAIN CEPEDA-PRADO

Postdoctoral fellow

Biography

 

Efrain studies the synaptic integration and connectivity of in vivo reprogrammed mouse and human neurons, with the aim of developing future therapies for diseases such as Parkinson's disease or Schizophrenia. He is using techniques such as patch-clamp electrophysiology, 3D morphology, and RNA sequencing at a single-cell level.  A scholarship from Lund University supports him.

SRISAIYINI KIDNAPILLAI

Postdoctoral fellow

Biography

 

Srisaiyini’s Ph.D. studies at Deakin University, Australia focused on understanding the molecular mechanisms of commonly prescribed Bipolar disorder drugs in order to understand how they bring about therapeutic effects (2015-2018). After joining the Ottosson Lab in 2019, she has been working on in vivo direct reprogramming of glial cells into interneurons. She has been supported by Wenner Gren postdoctoral fellowship for education in Sweden (2020-).

ANDREAS BRUZELIUS

PhD Student

Biography

 

Andreas' Ph.D. studies at Lund University are focused on disease modeling by using the direct conversion of adult human fibroblasts into GABAergic interneurons. He learned electrophysiology in the Ottosson lab which has become one of his key techniques. Apart from his own projects, he is part of many collaborations with other research groups where he performs whole-cell patch-clamp experiments.
