Urology Research

The University of Wisconsin Department of Urology is among the nation's leaders in research, with more than $2 million in funding each year. Here's a look at the doctors' research interests.


E. Jason Abel, MD

Dr. Abel conducts clinical, translational and basic research in urologic oncology. He currently is involved in several projects focusing on the development and metastasis of kidney cancer.


Dale E. Bjorling, DVM

Dr. Bjorling's interests include inflammation of the bladder due to non-infectious causes and mechanisms that modulate pain sensation and bladder healing. His primary emphasis is the causes and pathogenesis of non-infectious cystitis and and effects of infectious cystitis on the afferent nervous system.


Wade A. Bushman, MD, PhD

Dr. Bushman’s research interests focus on clinical research in bladder and pelvic floor dysfunction and basic research in prostate development and prostate cancer. Dr. Bushman is vice chair for research and academic affairs.


Tracy M. Downs, MD

Dr. Downs has a joint appointment with the UW Carbone Cancer Center. His clinical research focuses on developing new therapies for genitourinary cancers. Specific interests are: chemoprevention (bladder/ prostate cancer); bladder screening programs; outcomes research (non-muscle invasive bladder cancer and radical cystectomy); translational research (discovery of molecular and urinary biomarkers for bladder cancer); and quality of life outcomes (bladder/ prostate cancer).


Sean P. Hedican, MD

Dr. Hedican is co-director of the endourology fellowship and performs research in minimally invasive cancer treatments, gene therapy delivery systems, and understanding the immunology of cryoablation.


Walter J. Hopkins, PhD

Dr. Hopkins’ research interests focus on urinary infections and prevention of urinary tract infections. One particular area of interest is the potential benefits of cranberries.


David F. Jarrard, MD

Dr. Jarrard has a joint appointment with the UW Carbone Cancer Center. His clinical research emphasizes developing new therapies for genitourinary cancers. He has an active basic science laboratory within which he and his staff examine genetic and epigenetic alterations in prostate cancer.


John V. Kryger, MD

Dr. Kryger’s research interests are the effects of environmental toxins in male reproductive tract development, clinical outcomes of hypospadias repairs, and clinical outcomes of surgical management of neurogenic bladders.


Sarah E. McAchran, MD

Dr. McAchran has research interests in female urology include optimization of care pathways to improve surgical outcomes and clinical outcomes of female pelvic floor reconstruction.


Stephen Y. Nakada, MD

Dr. Nakada’s research focuses on pathophysiology of the ureter, endourologic and laparoscopic surgical techniques, and all aspects (medical and surgical) of urinary stone disease. Dr. Nakada oversees the endourology fellowship program and research.


David R. Paolone, MD

Dr. Paolone’s research interests are in the areas of benign prostate hyperplasia and penile disorders.


Kristina L. Penniston, PhD, RD

Dr. Penniston’s research interests include clinical nutrition in kidney stones and prostate cancer. Current research projects include comparative effectiveness of nutrition therapy in prevention, management, and treatment of stone disease; development of a porcine model for urolithiasis; and quality of life of patients with kidney stones.


Bruce L. Slaughenhoupt, MD

Dr. Slaughenhoupt has research interests in kidney stone development, treatment and prevention in the pediatric population.


Daniel H. Williams, IV, MD

Dr. Williams’ research interest is male infertility and includes the preservation of fertility in men with cancer, the effects of advanced paternal age and the environment on male reproductive potential, and clinical outcomes of male reproductive tract reconstructions.
