Meet the PI Members!

Karen Mruk, PhD

Assistant Professor
School of Pharmacy
University of Wyoming


Current Affiliation: I started my lab August 2018.  I'm an assistant professor at the University of Wyoming in the School of Pharmacy.

Previous Affiliation: I did my postdoctoral work in James Chen's lab at Stanford University. We were members of the Department of Chemical and Systems Biology and Department of Developmental Biology

Research Focus: In the CNS, specialized cells work together to differentiate, wire, and later die to form a completely integrated system. Our lab focuses on nervous system injury, degeneration and regeneration using zebrafish as a model. My lab is particularly focused on understanding the role bioelectricity plays in locomotor recovery and the genetic factors that govern this process.

Arndt F. Siekmann, PhD

Associate Professor, Department of Cell and Developmental Biology
Principal Investigator, Cardiovascular Institute (CVI)
Perelman School of Medicine at the University of Pennsylvania




In September 2018, I moved my laboratory from the Max-Planck-Institute in Münster, Germany to the University of Pennsylvania.

Previous address:
Laboratory for Cardiovascular Patterning
Max-Planck-Institute for Molecular Biomedicine
Röntgenstr. 20
48149 Münster

New address:
Department of Cell and Developmental Biology
Principal Investigator, Cardiovascular Institute (CVI)
Perelman School of Medicine at the University of Pennsylvania
1114 Biomedical Research Building
421 Curie Boulevard
Philadelphia, PA 19104

My research focus:
We study blood vessel development, mainly using zebrafish as a model system. In addition, we are using cultured cells to understand the epigenetic changes that occur during the adaptation of the vasculature to biophysical forces.


Hiring? I am hiring postdoctoral researchers.

Amber Stratman

Department of Cell Biology and Physiology, Washington University School of Medicine
NICHD/NIH, Brant Weinstein

My lab is interested in the mechanisms regulating blood vessel formation, stabilization and blood flow sensing during development and disease.

@crisprscan - Twitter,

I am starting my new lab (1st official day 1st February 2019) at the Andalusian Center of Developmental Biology (CABD) as Assistant Professor (Ramon y Cajal Fellow-Junior PI) in the University Pablo de Olavide (Seville, Spain).

I did my PhD (Department of genetics,University of Seville, Spain) under the supervision of Professor T. Benítez studying how environmental pH controls gene expression in a mycoparasitic fungus. Once I finished my doctorate, I moved to research projects more focused on new technologies and biomedical research and I did my first postdoc at CABIMER-CSIC (Seville, Spain) in the laboratory of Dr. Pintor-Toro studying molecular and cellular biology of cancer using mammalian cell lines as a model.  In 2013, I joined the laboratory of Prof. Antonio Giráldez at Yale University as a Research Associate Scientist to work on CRISPR-Cas gene editing tool and its application to study early development and human diseases using zebrafish as model.  I was recently awarded with a Ramon y Cajal grant allowing me to join Pablo de Olavide University (Assistant Professor) and CABD at Seville where I have just started my lab in February 2019 as Junior PI (Springboard PI). Currently, I am studying novel in vivo CRISPR applications to better understand early development in vertebrates.
