HiLIFE / Biomedicum Helsinki seminar by Bogdan Pasaniuc:
Dr Pasaniuc is an professor of Computational Medicine, Human Genetics and Pathology & Laboratory Medicine at UCLA. Dr Pasaniuc develops statistical and computational methods to understand the genetic basis of disease, focusing on under-represented populations, integrative genomics, and biobank studies. Dr Pasaniuc group developed machine learning methods to integrate epigenetic profiles within trans-ancestry studies to localize disease variants and genes; his group introduced transcriptome-wide association studies (TWAS) using predicted gene expression as a principled approach to identify disease genes for many traits such as Schizophrenia, Ovarian Cancer and Prostate Cancer. Dr Pasaniuc serves as Associate Director of Population Genetics of the Institute for Precision Health at UCLA that links the genetics of more than 150k patients with their electronic health record to predict health outcomes, to stratify patients based on their genetic risk to disease and to translate genomics to the clinic. Dr Pasaniuc also serves as PI for the Center for Admixed populations and Health Equity and for the Biomedical Data Science Training Program for Precision Health Equity at UCLA.
Welcome to this exciting seminar!

Special semnar by Prof Gyorgy Hajnóczky
Gyorgy Hajnóczky: Mitochondrial form and
function in the brain
Prof Gyorgy Hajnóczky from the Department of Pathology and Cell
Biology, Thomas Jefferson University, Philadelphia, is the Founding Director of
the MitoCare Center for Mitochondrial Imaging Research and Diagnostics.
Hajnóczky group was among the first to visualize mitochondrial energy and ion
metabolism in single live cells. They are credited with the discovery of
physically tethered contact sites between endoplasmic reticulum (ER)
and mitochondria, and that the ER-mitochondrial “synapses” enable calcium
signal propagation to the mitochondria to control both energy
production and cell death. They have also had major contributions to the
current understanding of mitochondrial maintenance and proper distribution by
fusion and movement. Hajnóczky group has invented numerous microscopy
techniques and probes to benefit the field. Their major
current focus is on the role of dysregulation of mitochondrial calcium
homeostasis, energetics and dynamics in human neuropathogenesis. For a meeting with Prof Hajnóczky, please
