Aaron Boes, MD, PhD

Principal Investigator

Dr. Boes' research focuses on the relationship of brain structure and function.  He has used a variety of approaches to this topic, including structural MRI, lesion mapping, and resting state functional connectivity MRI.  He recently developed a novel approach for investigating the network effects of focal brain lesions that integrates lesion mapping with normative data from the human connectome project.  Dr. Boes is also a physician and splits his clinical time between pediatric neurology and directing the Iowa Noninvasive Brain Stimulation Clinical Program.     Fileboes_biosketch_2020_.docx    Microsoft Office document iconboes_cv_7_2020.doc

Brandt Uitermarkt, MA

Research Specialist

Brandt has a Masters Degree in Behavioral and Cognitive Neuroscience.  He is involved with ongoing multimodal neuromodulation studies as well as structural and functional neuroimaging projects in the lab. 

Joel Bruss, BA

Research Manager

Joel has over a decade of experience in lesion mapping studies as well as structural and functional imaging.  Current projects focus on quantifying lesion load in white matter tracts and processing fcMRI data.

Fatimah Albazron, MS

Research Assistant

Fatimah has two Master's Degrees--one in Healthcare Emergency Management from Boston University and one in Cellular & Molecular Biology from KAUST. She is currently involved in tracing brain lesions for morphological and functional imaging studies. ​

Mark Bowren, BS

Graduate Student

Mark is a second-year Clinical Psychology Graduate Student and fellow of the Behavioral-Biomedical Interface Training Program under the mentorship of Dr. Dan Tranel. His work in the lab focuses on the use of neuroimaging to predict cognitive and behavioral deficits following brain damage.

Nicholas Trapp, MD, MS

Assistant Professor

Nick recently completed his residency in psychiatry at Washington University and has joined the University of Iowa Department of Psychiatry as a neuromodulation fellow.  He has an ongoing project that uses functional connectivity MRI for identifying individualized stimulation targets for a trial using repetitive TMS to treat traumatic brain injury-induced depression.

Justin Reber, PhD

Postdoctoral Research Fellow

Justin is a postdoctoral fellow working with Dr. Boes and Dr. Dan Tranel. His research focuses on how brain damage and brain stimulation affect cognition and behavior.

Darcy Waller, BA, BSc

Graduate Student

Darcy is a fourth-year graduate student in the Psychology Department's Behavioral and Cognitive Neuroscience program. She works with Dr. Jan Wessel and is completing a rotation in the lab to study the neural bases of motor inhibition using rTMS.


Nicholas Bormann

Nicholas Bormann, MD

Psychiatry Resident

Nick graduated from the Carver College of Medicine and is working as a Psychiatry Resident at Iowa.  He is part of the Physician Scientist Training Pathway and will be involved in improving and developing new neuroimaging methods in the lab.
