Hi, I am a Professor and Head of the Department Pharmacology and Toxicology at the Institute of Pharmaceutical Sciences at University of Graz. I am also a group leader at the Institute of Experimental and Clinical Pharmacology and Toxicology at the University of Freiburg.
I studied pharmacy and received my PhD from University of Freiburg, Germany (Supervisor: Prof. Lutz Hein), where my research focused on DNA methylation in cardiomyocytes in heart development and heart failure.
My postdoc in Prof. Bing Ren’s laboratory at the Ludwig Institute for Cancer, San Diego, centered on 3D chromatin organization and enhancer dynamics in cardiomyocyte differentiation and single cell epigenomic profiling of chromatin accessibility in mouse forebrain development. From 2017-2021, I was the Associate Director for Single Cell Genomics at the UCSD Center for Epigenomics (Director: Bing Ren). Here, my team set up state-of-the-art single cell (epi-)genomics research platforms for single cell (epi-)genomic profiling that enabled in depth studies of mouse and human tissues including brain, lung, heart and an atlas of chromatin accessibility across 30 human adult tissues.
The main objective of my lab's research is to dissect epigenomic and gene regulatory programs underlying tissue homoestasis, ageing as well as cardiovascular and kidney diseases.

Hi, I hold a double degree: a State Engineer in Biotechnology and a Master’s in Pharmaceutical Biotechnology from the National Higher School of Biotechnology Taoufik KHAZNADAR in Algeria, where I completed my thesis on marine exopolysaccharides and their applications in dermocosmetics. I also earned a Master’s in Bioengineering from BahçeÅŸehir University in Istanbul, Türkiye, where my research focused on developing novel hERG blocker QSAR models using machine learning-based classifiers.
My doctoral research focuses on uncovering cell-type-specific gene regulatory programs associated with autosomal dominant polycystic kidney disease using single-cell epigenomic approaches.

Hi, I'm a researcher with a passion for understanding the complexities of cardiovascular disease. I completed my studies in pharmacy at the University of Freiburg, where I focused my diploma thesis on gene expression changes in cardiomyocytes in the context of atrial fibrillation at the Institute of Experimental and Clinical Pharmacology and Toxicology.
Currently, I’m working on my doctoral thesis, where I’m uncovering cell-type-specific gene regulatory programs associated with cardiovascular disease. I use single cell epigenomic technologies to explore how different cardiac cell types undergo cellular remodeling during heart disease and development. My research integrates single-cell transcriptomic and epigenomic data to identify key epigenetic and gene regulatory pathways that drive these processes.
I’m deeply committed to advancing our understanding of heart disease and its underlying molecular mechanisms. Through my work, I hope to identify new therapeutic targets that could help prevent and treat cardiovascular disorders.

Hi, I studied pharmacy at the University of Tübingen and subsequently began my PhD at the Institute of Experimental and Clinical Pharmacology and Toxicology at the University of Freiburg.
My research focuses on the dissection of epigenetic processes underlying perinatal and postnatal adaptations of skin macrophage subtypes.
