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.

Mark Bowren, BS

Graduate Student

Mark is in his last year as a 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.



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.


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.



Jax Skye, BS

Graduate Student

Jax is a graduate student in the Interdisciplinary Graduate Program in Neuroscience. His current project uses lesion network mapping to elucidate networks involved in value-based decision making. 


Hassan Ahamed, BS

MSTP Student

Hassan is a medical student in the Medical Scientist Training Program at Iowa. His current project uses lesion network mapping to better understand the localization of central post-stroke pain.


Carrie Shea, MA

Clinical Trials Research Assistant / Data Manager

Carrie has a Masters in Clinical Psychology from UNI and recently joined the Boes and Hwang Labs as a study coordinator for the Iowa Lesion Registry.   


Alan Romanowski

Alan Romanowski, BS

Research Intern

Alan is a recent graduate from the University of Iowa and a new research intern in the Boes lab. He is participating in multiple projects and is interested in applying to graduate school for neuropsychology in the fall of 2022.


Maya Skye Dosembet

Maya Skye Dosembet, BS

Research Intern

Maya is a recent graduate from the University of Iowa and a research intern at the Boes and Jiang Lab. She is also the fNIRS Coordinator and Administrator at the University of Iowa Stead Family Hospital's Center for Disabilities and Development. Currently, she is involved in multiple projects involving neuroimaging using fNIRS and is working on an independent project analyzing personality change in individuals with focal brain lesions. Additionally, she is applying to Child Clinical Psychology graduate programs for the fall 2023 term.
