Mohamad E. Allaf, MD

      Dr. Allaf is an Assistant Professor of Urology and Biomedical Engineering at the Brady Urological Institute and Director of Minimally Invasive and Robotic Surgery at the Johns Hopkins Hospital. He joined the staff after receiving his undergraduate and medical degrees from the Johns Hopkins University and completing his residency and advanced training in Urology at Johns Hopkins as well.
     His main clinical interest includes the treatment of kidney tumors and prostate cancer in the least morbid way possible. He specializes in the management of kidney tumors via laparoscopic (total and partial kidney removal) and percutaneous (non-surgical) approaches. He also has an interest in the careful and active observation of select small kidney tumors. His other areas of focus include performing nerve sparing radical prostatectomy in all its forms (open, laparoscopic, and robotic) as well as reconstructive laparoscopy (pyeloplasty) and laparoscopic management of testicular cancer (retroperitoneal lymph node dissection).
     His research endeavors involve investigating approaches to minimize the morbidity of urologic surgery and the development of ways to decrease injury to the neurovascular bundles and hasten erection recovery following radical prostatectomy. Dr. Allaf has been the recipient of numerous academic awards, including placing first in the 2005 American Urological Association clinical and laboratory research annual essay contests. He has written and published numerous research articles, textbook chapters, patents and video presentations in the field of Laparoscopic and Robotic Urologic Surgery.

Trinity J. Bivalacqua, M.D, Ph.D

Trinity J. Bivalacqua, M.D., Ph.D., Assistant Professor of Urology and Oncology, was born in New Orleans, Louisiana and graduated from Tulane University with undergraduate, graduate and medical degrees. He joined the faculty after completing his General Surgery and Urology training at Johns Hopkins Hospital. He also received an American Urological Association (AUA) Foundation Fellowship for his pioneering work on neuroregulatory control of penile erection.

Dr. Bivalacqua has an active clinical practice in Urologic Oncology, Andrology and Benign Prostatic disease.  His specific interest is in Prostate, Bladder and Penile cancers, Erectile Dysfunction, Peyronie’s Disease, Priapism.  He has expertise in open, laparoscopic and robot treatment of these genitourinary malignancies.

Dr. Bivalacqua has received national and international recognition for his research involving the pathophysiology and novel treatment strategies for Erectile Dysfunction and Priapism.  His laboratory currently investigates novel molecular pathways that are involved in post-radical prostatectomy erectile dysfunction, diabetes-induced erectile dysfunction, and sickle cell disease-associated priapism. He was the first person to describe the use of gene therapy targeting the endothelium of the penis for the treatment of erectile dysfunction.  Through his scientific discoveries, new pharmacological and gene therapies have been developed for male erectile dysfunction.

Misop Han, M.D.

     Dr. Misop Han is an Associate Professor of Urology at the Brady Urological Institute at The Johns Hopkins Hospital. He received his undergraduate, medical school and urology training at Johns Hopkins. After his training, he worked as an Assistant Professor of Urology at the Feinberg School of Medicine at Northwestern University and as a urologist at Northwestern Memorial Hospital in Chicago, Illinois. Dr. Han was head of Northwestern University's clinical database for prostate cancer research. In 2006, he was recruited back to join the faculty at the Brady Urological Institute at Johns Hopkins Hospital.
    Dr. Han is a board-certified urologist whose main clinical focus is in urological oncology with a special emphasis on prostate and kidney cancers. He specializes in nerve-sparing radical retropubic prostatectomy, robotic-assisted laparoscopic radical prostatectomy and laparoscopic nephrectomy.
     Dr. Han has received recognition for his research involving the outcome of surgery for prostate cancer and has received national awards for his research. His research interests include the outcome of radical prostatectomy and prediction modeling (what happens to men following surgery for prostate cancer). He has published extensively in these subjects(click here for details). He is actively involved in several clinical research projects with the database of more than 14,000 men who received surgery for prostate cancer at The Johns Hopkins Hospital.

Brian R. Matlaga, M.D., M.P.H.

      Dr. Brian Matlaga is Associate Professor of Urology at The Brady Urological Institute and the Director of Stone Disease at Johns Hopkins Bayview Medical Center. Dr. Matlaga came to Johns Hopkins after completing a fellowship in minimally invasive surgery and metabolic stone disease. During his fellowship he was designated an American Foundation for Urologic Disease Research Scholar, and was awarded the Outstanding Research Scholar honor in recognition of his work involving the treatment of patients with stone disease.
      Dr. Matlaga’s main clinical interest is the minimally invasive treatment of patients with metabolic stone disease, including percutaneous nephrolithotomy, ureteroscopy, and shock wave lithotripsy. In addition, Dr. Matlaga has an interest in the holmium laser enucleation of the prostate (HoLEP), a minimally invasive laser therapy for men with benign prostatic enlargement.
      As the Director of Stone Disease, Dr. Matlaga is actively engaged in clinical and basic science research addressing the questions of: Which patients develop stones? How do stones form? How well are we treating patients with stones?

Christian Pavlovich, M.D

Christian Pavlovich, M.D. is Director of Urologic Oncology at the Johns Hopkins Bayview Medical Center. He came to Johns Hopkins after completing a urologic oncology fellowship at the National Cancer Institute in Bethesda, Maryland.

Currently, he applies his expertise in open, laparoscopic, and other minimally invasive techniques primarily to patients with urologic cancers. His main current focus is the treatment of prostate, bladder, and kidney cancers with minimal morbidity and maximal oncologic efficacy. To this effect, he has developed a busy cancer practice, where he offers nerve-sparing laparoscopic, robot-assisted laparoscopic, and open radical prostatectomy for prostate cancer, laparoscopic radical cystectomy for bladder cancer, and open and laparoscopic approaches to the kidney for kidney cancer.
