Masatoshi Inoue, PhD, joins the faculty of the Biophotonics Research Center as an assistant professor of radiology. Inoue aims to establish a research program combining protein engineering and tool development with systems neuroscience to study the neural representations of adaptive and maladaptive social behaviors. He works on imaging tools including developing a new class of genetically encoded photoacoustic sensors for noninvasive brain-wide imaging of neural activity.

Inoue earned his doctorate in neurochemistry from the University of Tokyo. He comes to MIR from Stanford University, where he has been a life science research associate after completing his postdoctoral training in 2020.

Stephanie Kim, MD, PhD, joins the interventional radiology section as an assistant professor of radiology. Kim previously worked at the University of Cincinnati, where she was an assistant professor of radiology in the Division of Vascular and Interventional Radiology. She served as an associate program director of the interventional radiology residency and as director of IR medical student education. Recently, she was honored with the department’s Harold B. Spitz Resident Teaching Award.

Kim earned her medical and doctoral degrees from the University of Chicago’s Pritzker School of Medicine MSTP program. She completed her diagnostic and interventional radiology residencies at the University of Pennsylvania.


Headshot of Thomas Kim, MD.

Thomas Kim, MD, joins the neuroradiology section as an assistant professor of radiology. He specializes in neuroradiology with expertise in neuroangiography as well as advanced MR applications.

Previously, Kim worked at Indiana University School of Medicine, where he was an associate professor. He also served as an associate professor and director of artificial intelligence at Saint Louis University School of Medicine as well as on the faculty of the University of Washington and Mayo Medical School.

Kim earned his medical degree from WashU Medicine and completed his diagnostic radiology residency at Allegheny General Hospital in Pittsburgh, followed by a two-year neuroradiology fellowship at the University of Michigan. He also holds an MBA from Northwestern University.


Headshot of Satya Kothapalli, PhD.

Satya Kothapalli, PhD, joins MIR as an instructor of radiology in the Biomedical MR Center. Kothapalli previously served as a postdoctoral research associate and a staff scientist in the Yablonskiy Lab, where he helped develop new MRI-based methods for in vivo studying of humans and animals in health and disease. His research interests include neurodegeneration and quantitative MRI.

Before coming to MIR, Kothapalli earned master’s degrees from Blekinge Institute of Technology in Sweden and Andhra University in India. He completed his doctorate at KTH Royal Institute of Technology in Stockholm.


Headshot of Megan O'Brien, DO.

Megan O’Brien, DO, joins our physician practice and will be providing general radiology services at multiple regional sites. In July, she will transition to the neuroradiology section to join our fellowship program.

O’Brien earned her medical degree from the Kirksville College of Osteopathic Medicine and completed a diagnostic radiology residency at Saint Louis University School of Medicine.
