Associate Professor of Radiology and Radiological Science

Research Interests: Stem cells; brain, stroke; myopia; intra-arterial


Dr Janowski completed residency in neurosurgery in 2009 at the Medical University of Warsaw, Poland in 2009, and after defending his PhD thesis in 2010 at the Mossakowski Medical Research Centre, Polish Academy of Sciences, he moved to the United States in 2011 and joined the Department of Radiology and Institute for Cell Engineering at the Johns Hopkins University as a post-doctoral fellow. In 2012 he has been promoted to the level of Assistant Professor and in 2016 to the level of Associate Professor. more

Research Summary

The Janowski lab centers on the routes of delivery of therapeutic agents to the brain as well as explores new applications for stem cells. 

He pursues a research on the use of intra-arterial and intraventricular routes to provide therapeutic agents at the high-dose to the central nervous system. The employment of body fluids such as CSF and blood makes the procedures less invasive. The major contribution of dr Janowski lab lies within application of MRI guidance to intra-arterial and intra-ventricular procedures, which facilitated the precision and predictability. He is particularly devoted to real-time MRI guidance of brain infusions using novel contrast mechanisms such as chemical exchange saturation transfer (CEST), which allows for multicolor interventional neuroradiology. 

Beyond the research on delivery routes, Dr. Janowski explores the new applications for stem cell research. He is involved in the use of stem cells for degenerative disc disease. Dr Janowski has also pioneered the idea of using stem cells to prevent progression of myopia, a worldwide pandemic that is expected soon to be the most frequent cause of blindness, and is establishing research on myopia in his laboratory.


Dr. Janowski's laboratory is located in the Institute for Cellular Engineering (ICE) in the MRB building, consisting of 500 sq. ft. of fully equipped general laboratory space for molecular biology, biochemistry and tissue processing, and, a 250 sq. ft. tissue culture room with four incubators for ambient and low oxygen environment, inverted microscope, automated cell counter and high end Zeiss Observer.

Z1 microscope equipped with motorized scanning stage, ApoTome and ORCA-Flash 4.0 CMOS camera (Hamamatsu). There is also available a Dell workstation dedicated to image processing (Matlab, Amira) and a stereotaxic apparatus. The P.I. has an office in the MRB (ICE) building and an adjacent lab with six desks for postdocs, visitors, and students with total office/desk space of about 500 sq. ft. 

Dr Janowski has also an access to the start-of-the art imaging equipment including small animal and clinical scanners, as well as small and large animal facilities.
