Joun Lee, B.A.

Lab Manager/Study Coordinator


  • B.A. Psychology, Emory University, Atlanta, Georgia, USA

About Joun: 

Joun joined the lab in September 2017 after completing his Bachelors degree at Emory University and working as a research assistant at Boston Children’s Hospital where he studied the biology of motor neurons in mouse models of ALS. He coordinates several mouse developmental and cancer studies and manages the maintenance and breeding of several Tet mouse strains. He also oversees the daily lab maintenance.

Stephanie Chrysanthou, PhD

Postdoctoral Fellow


  • B.Sc. Biochemistry and Molecular Biology, University of Bristol, UK

  • M.Res. Biomedical Research, Imperial College London, UK

  • Ph.D. Epigenetics, Babraham Institute, University of Cambridge, UK

About Stephanie:

Stephanie joined the lab in August 2017 after completing her PhD in Epigenetics in Dr. Myriam Hemberger’s lab at the Babraham Institute in UK where she studied the role of Tet enzymes in regulation of trophoblast stem cell biology.  She is interested in dissecting the molecular functions of Tet enzymes in regulating gene expression programs in ESCs and their implications in stem cell self renewal and pluripotency.

About Qin:

Qin joined the lab in June 2018 after completing a postdoctoral fellowship in Dr. Guo's lab at Huazhong University where she studied the role of transcription factors and microRNAs in gene regulation in cancer. She is interested in investigating Tet-mediated epigenetic regulation of ES cells and cancer using a systems biology approaches.

Antoine Abou Jaoude, PhD

Postdoctoral Fellow


  • B.Sc. Biochemistry, Lebanese University, Fanar, Lebanon

  • M.Sc. Molecular Biology, Lebanese University, Hadath, Lebanon

  • Ph.D. Biology, University of Strasbourg, Strasbourg, France

About Antoine:

Antoine joined the lab in July 2019 after completing his PhD in Dr. Philippe Boucher laboratory at the University of Strasbourg where he studied signaling pathways involved in atherosclerosis and chondrogenesis using cellular and transgenic mouse models. He is interested in investigating how Tet enzymes are regulated in ESCs and how these mechanisms contribute to ESC pluripotency, development and cancer.

Julio Flores, BSc

M.D.Ph.D. Graduate Student


  • B.Sc. Molecular and Cellular Biology, University of California Merced School of Natural Sciences, CA, USA

  • M.D. & Ph.D. Dual Degree In Progress, Albert Einstein College of Medicine, Bronx, New York, USA

About Julio:

Julio joined the lab for his Ph.D. thesis work in August 2019. He has been part of MARC-U*START and UPSTaRT programs and the recipient of several awards as an undergraduate student. He worked as a research specialist at UCSF before joining Einstein M.D.Ph.D. Program in 2017. He is interested in investigating how the enzymatic and non-enzymatic functions of Tet enzymes regulate stem cell identity and plasticity, and their implications in development and cancer.

  • Ph.D. Degree In Progress, Albert Einstein College of Medicine, Bronx, New York, USA

About Harmony:

Harmony joined the lab for her Ph.D. thesis work in March 2020. She comes a with Bachelor degree in Health Science & Biology followed by two years of research experience as a technologist at Einstein where she studied the role of Colony Stimulating Factor 1 Receptor (CSF-R) in macrophage and microglia biology using mouse models. She is interested in understanding how DNA methylation and demethylation dynamics are regulated by Tet enzymes during stem cell differentiation and embryogenesis.
