Surgeon Scientist

Dr. Rose Khavari is a Professor of Urology at Houston Methodist Institute for Academic Medicine and Weill Cornell Medical College. Dr. Khavari received her M.D. at the University of Texas Medical Branch, and with an interest in functional urologic surgery, following her residency at Baylor College of Medicine she completed her fellowship in male and female continence, pelvic reconstructive surgery and neurourology at Houston Methodist Hospital. Beside her clinical and research responsibilities, Dr. Khavari is also the program director for Urology residency Program at Houston Methodist Hospital.

Faculty Profile

Clinical Profile


Betsy Salazar, PhD

Assistant Research Professor

Her role as Assistant Professor in the Khavari lab is focused on applying her extensive knowledge in electrophysiology and neuromodulation techniques to study the brain-bladder connection. Dr. Salazar received a PhD in Biomedical Engineering from the University of Houston in 2015. She then began postdoctoral training at the Houston Methodist Research Institute under the guidance of Dr. Alvaro Munoz and Dr. Timothy B. Boone, where she focused on the electromyographic characterization of the lower urinary tract in intact and spinal cord injury (SCI) rodent models. She continued her postdoctoral training by joining the Center for Neuroregeneration under the direction of Dr. Philip J. Horner, where she worked on the use of therapeutic agents to promote remyelination and motor recovery following SCI. She also has interest in functional neuroimaging and neuronavigation to develop noninvasive therapies for neurogenic bladder patients.

Hamida Rajab

Research Coordinator

Hamida graduated with a B.S. in Biotechnology/Genetics from the University of Memphis. With many years of experience in clinical research, Hamida facilitates study recruitment and ensures all of our clinical trials and studies run smoothly and comply with good clinical practice.


Kris Hoffman, BSME

Biomedical Engineer

Kris graduated with a B.S. in Mechanical Engineering from the University of Houston. With a research background in tissue engineering, neuroimaging, and neuroregeneration, Kris is interested in using neuroimaging modalities to further current understandings on the brain and spinal cord control over the bladder. He is also involved in developing mechanical prototypes used in clinical research and rehabilitation. 


Julu Benoy

Clinical Research Specialist


Arda Bayer

Graduate Research Fellow

After graduating from Boğaziçi University in Istanbul, Turkey with a degree in electrical and electronics engineering, Arda traveled to the US and began his graduate career at Rice University in Houston. At Rice, under the direction of Dr. Behnaam Aazhang, he wanted to find other areas to apply his skills and found the Khavari lab! While in the Khavari lab, Arda will help with analysis and statistics for various ongoing and completed projects involving medical imaging modalities.



Neurogenic Bladder Research Group (NBRG)

As an active member of the Neurogenic Bladder Research Group (NBRG), Dr. Khavari and her research team have been collaborating with NBRG on many projects to improve the quality of life, surgical outcomes, and clinical care of individuals living with neurogenic bladder.



Timothy Boone, MD, PhD

As the Director of the Houston Methodist Academic Institute, Dr. Boone has been a mentor to Dr. Khavari since 2006. With over 25 years of professional and academic career focused on neurourology, Dr. Boone has been supporting and advising majority of our projects in the past decade. Dr. Boone’s unapparelled mentorship has been instrumental in shaping Dr. Khavari’s academic career.


Doroles Lamb, PhD

As the Vice Chair for Research in the Department of Urology at Weill Cornell Medicine, Dr. Lamb has been a mentor to Dr. Khavari since her residency training. With an extensive background in both clinical diagnostic and basic science in the fields of urology, prostate cancer, and genitourinary birth defects, Dr. Lamb has been supporting many of our research projects and grant applications. Dr. Lamb is an excellent researcher with various funding mechanisms through NIDDK who has mentored Dr. Khavari for over a decade and has shaped her academic career into a rising surgeon-scientist.


Christof Karmonik, PhD

As the Director of the Houston Methodist Translational Imaging Center, Dr. Karmonik has been been working closely with us on numerous projects on the brain control of the bladder since 2013. With more than 20 years of experience in clinical and preclinical MRI research, Dr. Karmonik offers valuable insights on the planning, execution, and analysis in many of our studies.

Ricardo Gonzalez, MD

Dr. Gonzalez is an Associate Professor of Urology at Houston Methodist Institute for Academic Medicine and Texas A&M University. With an expertise in minimally invasive treatments for voiding dysfunction, he has been a strong collaborator in many of our studies in benign prostatic hyperplasia (BPH) and Pelvic Organ Prolapse (POP). Many of his patients participate in our clinical trial.


Santosh Helekar, MD, PhD

Dr. Helekar is one of the inventors of the Transcranial Rotating Permanent Magnet Stimulator (TRPMS), a device used in one of our clinical trials. With many years of expertise, Dr. Helekar has been a consultant and collaborator supporting all our TRPMS-related studies.


Rachel High, DO

Dr. High, a skilled urogynecologist, is interested in evaluating the higher neural changes following the administration of overactive bladder (OAB) medications. We have been collaborating over the past two years to create the first multi-center human trial designed specifically to study cognitive effects of medications use in OAB.


Brian Miles, MD

Dr. Miles is a Professor of Urology at Houston Methodist Institute for Academic Medicine and Weill Cornell Medical College. With and expertise in robotic surgery and a specialization in urologic oncology, especially cancer of the prostate, Dr. Miles has been a collaborator in many of our studies on benign prostatic hyperplasia (BPH) and male urinary incontinence. Additionally, Dr. Miles has been a mentor to Dr. Khavari over the past decade helping shape her academic urology career. Many of Dr. Miles patients participate in our clinical trials.


Argyrios (Argy) Stampas, MD

Dr. Stampas is a physiatrist at TIRR Memorial Hermann and has a few active trials evaluating transcutaneous tibial nerve stimulation in acute and chronic spinal cord injury patients. With a clinical interest in spinal cord injury rehabilitation, Dr. Stampas has been a collaborator in many of our studies, especially on bladder and bowel management of neurogenic patients.
