"During my interview day at the University of Iowa, it was clear that the neurosurgery program offered extremely well-rounded training with strong clinical, operative, and research experience. It was also clear that the residents and faculty at Iowa are a cohesive, friendly, and hard-working group that would provide excellent mentorship and collegiality. Overall, the program's vast resources and commitment to training future leaders in academic neurosurgery made Iowa the preferred choice for my residency training."

“Having had the chance to pursue a post-doctoral fellowship in the Department of Neurosurgery at the University of Iowa, I was able to witness firsthand the cutting-edge scientific research and world class patient care that is rendered to our patients on a day to day basis. The diverse array of clinical presentations as well as volume of operative cases was also unparalleled. In addition, the utmost emphasis in training future academic neurosurgeons, who are leaders in their respective subspecialties along with the camaraderie and friendship among the residents, made choosing Iowa neurosurgery training program an easy choice.”

Clinical and research interests

I have keen interest in pursuing novel treatment approaches and research in the field of neuro-oncology, particularly in immunotherapy and the role of nanotechnology in the design and delivery of cell-specific anticancer molecule and their effect in GBM tumor kinetics.

“During my sub-internships around the country, I was impressed with the uniform consensus around the excellent track record of producing well trained academic neurosurgeons at the University of Iowa.  During my interview at the University of Iowa, I was struck by the enthusiasm for and commitment to structured resident mentorship by Dr. Howard and Dr. Greenlee, as well as the two dedicated years for research which can take place anywhere in the world. After ranking Iowa highly and being fortunate enough to match here, I can say with confidence that if being an academic neurosurgeon is your career goal, then the University of Iowa should be a program on your radar.”
