Post-doctoral Fellow

Ilanit Itzhaki received her PhD from the Technion Israel Institute of Technology where she worked on modeling familial arrhythmogenic syndromes (LQT and CPVT) using human iPSC-derived cardiomyocytes at Prof. Lior Gepstein’s lab. Itzhaki joined the Wu lab December 2014 and is currently studying electrophysiological cardiac maturation.

Chun Liu, PhD
Post-doctoral Fellow

Chun Liu received his PhD of Stem Cell Biology from Peking University (2014) in China. He worked on somatic reprogramming and differentiation of tissue cells (like hepatocyte and endothelial cells) from induced pluripotent stem cells (iPSCs). During his PhD, he have demonstrated a new way to reprogram adult somatic cells to become iPSCs using only chemical small molecules, without the addition of extra genes that could introduce the risks of mutations for cancer. In 2015, he joined Wu lab as a postdoc fellow, and he is interested in cardiovascular disease modeling and potential drug screening.

Praveen received his PhD in Pharm Sciences from N Dakota State Univ. Doctoral research elucidated the effects of melatonin on NO/cGMP/BKCa signaling pathway in coronary arteries and the hTRPA1 and TRPV4 channel drug discovery program at Neuronal targets and Heart failure discovery performance unit, GlaxoSmithKline. He joined Wu lab in 2012 and will research the electrophysiological characterization of iPSC-derived cardiomyocytes as an in-vitro screening platform for cardiotoxicity assessment of NCEs and in regenerative medicine.

Mingtao Zhao, PhD
Post-doctoral Fellow

Mingtao Zhao received his BS in Biological Science (2005) and DVM from Northwest A&F University (2010) in China. He then completed his Ph.D. under the mentorship of Dr. Randall Prather at the University of Missouri-Columbia in 2013, where he investigated DNA methylation and hydroxymethylation in mammalian gametes and early embryos. He joined Wu lab as a postdoc fellow in Jan 2014. He is interested in epigenetic modifications in cardiac differentiation and cardiovascular disease.

Haodi Wu, PhD
Post-doctoral Fellow

Haodi Wu was granted his Ph.D. in Peking University, where he was working on the structural/functional remodelings and the underlying molecular mechanisms of cardiomyocytes in heart failure. Joined the lab in 2012, combining multiple functional imaging techniques, his current research is focusing on the beta adrenergic signaling regulation in normal and diseased hiPSC-CMs and the potential treatment of dialated cardiomyopathy.

Alexandra Holmström, PhD
Post-doctoral Fellow

Alexandra Holmström received her PhD in Medicine from Gothenburg University, Sweden where she worked on the clinical relevance and potential mechanism of biomarkers in elderly heart failure patients. Her research focuses on generation of cardiomyocytes from rhesus iPS cells and their applications for treating heart disease in the form of transplantable in vitro engineered tissues, as a way to better understand the potential use of human iPS cell-derived tissues in clinical trials. Alexandra joined the Wu lab March 2014.


Elena Matsa, PhD

Elena Matsa received her Ph.D. from the University of Nottingham, UK, where she studied the epigenetic mechanisms of induced pluripotent stem cell derivation. She then progressed to a postdoctoral fellowship at the University of Nottingham working on cardiac differentiation of pluripotent stem cells and modeling of the cardiac arrhythmia syndrome known as long-QT. Dr. Matsa joined the Wu lab in 2012 and she is currently studying the molecular mechanisms of dilated cardiomyopathies.
