Alexander Cook

PhD Student

alexcook(at)uni-mainz.de

I was born in Nottingham in the UK, and attended Nottingham Trent University to study physiology and pharmacology B.Sc. Subsequently, I moved on to a master’s degree in neuroscience at Keele University, during which, I carried out my research project at the University Medical Center Freiburg, Germany, concerning olfactory function in an animal model of depression. In April of 2017, I joined Professor Ryu's lab with an IMB International Ph.D. Programme Scholarship where I develop a zebrafish model of stress resilience to identify novel molecular resilience mechanisms.

Dr. Helen Eachus

Post-doctoral Scientist

I am originally from Manchester, UK and studied for my Bachelor’s degree and then Ph.D. at the University of Sheffield, UK. My interdisciplinary Ph.D. project, supervised by Dr. Penny Watt, Professor Marysia Placzek and Dr. Jon Wood was an investigation of the effect of disc1 on the stress response in zebrafish. Subsequently I took a position as a post-doctoral researcher at the University of Sheffield, where I worked on two projects. The first project, in the lab of Dr. Vincent Cunliffe, was regarding the epigenetic embedding of stress responses in the zebrafish brain, whilst the second project, supervised by Dr. Nils Krone, focused on the characterisation of a zebrafish model of 21-hydroxylase deficiency. In 2019 I joined the lab of Professor Soojin Ryu, where I am working on identifying novel molecular mechanisms that underlie acute responses to stress.

Prof. Soojin Ryu, PhD

Principal Investigator

I was born in Seoul, Korea, but grew up in New York City. I got my bachelor’s degree from Harvard and my Ph.D. at the University of California, Berkeley at the laboratory of Prof. Robert Tjian, before moving to Freiburg, Germany, for my postdoc at the laboratory of Prof. Wolfgang Driever. In Freiburg, I started working with zebrafish and have been continuing to work with zebrafish ever since. After my postdoc, I was a group leader at the Max Planck Institute for Medical Research in Heidelberg before moving to Mainz as a professor. I am fascinated by how stress hormones alter our behavior and the brain and would like to understand how stress resilience can be developed and fostered. 

Dr. Holger Beckmann

Senior Scientist

hobeckma(at)uni-mainz.de

I was born in Bielefeld, Germany and performed my undergraduate studies in Kaiserslautern and Freiburg. During my PhD work at the Max Planck Institute for Immunology in Freiburg at the laboratory of Prof. Dr. G. Koehler, I had a chance to move to America on DAAD scholarship. I ended up performing much of my PhD work at the University of Pennsylvania, Medical School, at the laboratory of Prof. T. Kadesh. For my postdoc, I went to University of California, Berkeley and investigated biochemical mechanisms of transcriptional regulation at the laboratory of Dr. Robert Tjian. Afterwards, I left Academia to join a Start-Up biotech venture in South San Francisco and later moved to Germany to continue to work in biotech/pharmaceutical sector where my expertise was developing high-throughput screening system and assay for drug discovery. I moved back in Academia recently in order to develop high-throughput screening platform using zebrafish to identify novel stress regulators.

Dr. Jatin Nagpal

Post-doctoral Scientist

jatin.nagpal(at)uni-mainz.de

I was born in Delhi, India, and obtained my bachelor’s degree in Biochemistry at the University of Delhi. Thereafter, I switched continents and moved to Germany where I pursued a master’s degree in Neuroscience at the International Max Planck Research School, University of Göttingen. For my Ph.D., I moved to Frankfurt where I worked on developing and implementing novel optogenetic tools in Caenorhaditis elegans with Prof. Alexander Gottschalk at the BMLS, University of Frankfurt. Currently, I am working as postdoc, investigating molecular mechanisms underlying stress and resilience in Zebrafish.

Dr. Min-Kyeung Choi

Post-doctoral Scientist

mk.choi(at)uni-mainz.de

I was born in Busan, Korea. I got a bachelor’s and a Ph.D. degree from Konkuk University, Seoul, in animal biotechnology and genomics. Subsequently, I had a chance to get a postdoc position in the same University with the Korean national fellowship. During my Ph.D. period, I mainly focused on discovering innate immune genes in animal genomes and characterizing tissue or disease-specific gene expression with its associated DNA methylation patterns. I joined the lab of Prof. Ryu in March 2018 as a postdoc to figure out the epigenomic and molecular mechanisms underlying regulating the cell fate and plasticity during the developmental stages under stress using the zebrafish model. 

Dr. Sara Kuntz

Post-doctoral Scientist

kuntzs@uni-mainz.de

I grew up in Oldenburg, Germany, and studied biology at the University of Mainz where I first got interested in the neurobiology of learning and memory. With a DAAD scholarship I had the chance to work with Prof. Sokolowski in Toronto, Canada, on the behavioral effects of a genetic polymorphism. For my Ph.D., I joined the lab of Prof. Strauss at the University of Mainz and focused on the neurogenetic analysis of a working memory. After my graduation, I left academia and worked for a company in applied human genetics. In February 2018, I decided to go back to academic science and started my postdoc with Prof. Ryu at the University Medical School in Mainz. Back in the neurobiology field, I am interested in the molecular mechanisms of acute stress responses.

Siyong Kim

I was born in Seoul in South Korea, and achieved my bachelor's degree in Biomedical Engineering and Brain-Cognitive Sciences at the Korea University in Seoul. After that, I worked in the Center for Bionics of Korea Institute of Science and Technology (KIST) for a year while preparing my graduate school. I started the research project for my master's degree at Seoul National University in Korea. In October of 2017, with an IMB International Ph.D. Programme Scholarship, I moved to Mainz in order to elucidate the molecular mechanisms underlying resilience to stress by using zebrafish in Professor Ryu's lab.

Johanna Hoffmann

Master's Student

jhoffmann@uni-mainz.de

I was born in Karlsruhe in Germany and studied biosciences at the University of Heidelberg. During my bachelor’s thesis, I had the opportunity to work with zebrafish at the Institute of Toxicology and Genetics at KIT in Karlsruhe. When I moved on to a master’s degree in biomedicine at Johannes Gutenberg-University of Mainz, I first joined Professor Ryu’s lab as a student assistant. Having enjoyed working with fish in the past, I decided to stay in the lab for my master’s thesis. I am interested in characterizing the endocrine and behavioural stress responses in medaka larvae.
