Michael Hsieh, MD, PhD was recruited to Children’s National and the George Washington University to serve as Director of Transitional Urology. This joint venture is the East Coast's first clinical program dedicated to the care of adolescents and young adults with congenital urologic disorders. Many of these patients have chronic cystitis and are at increased risk of bladder cancer, diseases which dovetail with Dr. Hsieh’s research interests. Dr. Hsieh also is the Stirewalt Endowed Director of the Biomedical Research Institute near Children’s National’s satellite facilities in Rockville, MD, where he runs a bladder biology research group and is developing a broader microbiology research program across multiple laboratories.

Massoud Majd, MD, is an internationally known expert in the field of Nuclear Medicine. He frequently supervises the weekly Uro-radiology conference in which capacity he lends his broad expertise in the indications for and interpretations of various diagnostic radiographic tools. He has produced landmark work in the field of pediatric urology nuclear imaging.
Aaron Krill, MD, joined our division in January of 2016. Dr. Krill’s fellowship training emphasized traditional open surgery, as well as laparoscopic and robotic surgery. He considers it his mission to apply minimally invasive and robotic techniques whenever possible to improve outcomes and decrease morbidity in pediatric reconstructive urologic surgery. Dr. Krill’s areas of research interest include adolescent varicoceles, antenatal hydronephrosis, congenital solitary kidneys and ureteroceles.

Tanya Davis, MD, completed her Urology residency at the Medical College of Wisconsin (Milwaukee, Wisconsin), and prior to that received her MD degree from Albany Medical College (Albany, New York). She is a graduate of the Leadership in Medicine Program at Union College (Schenectady, New York), where she simultaneously completed her undergraduate work and an MS in Healthcare Management.
She was initially drawn to Pediatric Urology as a sub specialization of Urology due to the special nature of the relationship between a physician, child and their family and fostering this relationship is a top priority in her practice. Her clinical interests range from common, outpatient procedures to more complex reconstructive surgery and minimally invasive, robotic surgical techniques. Her research interests relate to quality improvement and process mapping, with the goal of helping patients and their families receive the best possible urologic care in an efficient (and safe) manner.
Dan Casella, MD. Originally from Baltimore, MD, Dr. Casella will be joining the faculty after completing his pediatric urology fellowship at Vanderbilt University. He earned his undergraduate degree in molecular biology at The University of Colorado at Boulder, attended Eastern Virginia Medical School and completed his residency at The University of Pittsburgh. Throughout his training, Dr. Casella has maintained a strong interest in basic science research, participating in studies examining the molecular epidemiology of bladder cancer, programmed cell death, and ureteral development. His research is currently focused on novel mechanisms of modulating bladder function through peripheral nerve (posterior tibial) stimulation, and the molecular mechanisms which drive cloacal membrane and genital tubercle development.
- Subspecialty interests: treatment of hypospadias, end stage voiding dysfunction and disorders of sexual differentiation
