Dr. Lloyd E. Ratner, MD, MPH, FACS, will present

Transplantation at Columbia University. Prior to joining the faculty

University in Baltimore, and served as the Chief of Solid Organ
Transplantation at Thomas Jefferson University in Philadelphia.

Access to organ transplantation has been Dr. Ratner’s major academic
interest. Dr. Ratner has been a leading innovator in transplantation
for two decades. In 1993, he performed the world’s
first dual renal transplant. In 1995 (with Dr. Louis Kavoussi) he
performed the first laparoscopic donor nephrectomy, and set the
stage for its widespread adoption, which resulted in a profound
increase in living donor kidney transplantation. Dr. Ratner has
made significant contributions in overcoming immunologic incompatibilities
that prohibited transplantation. He devised the
plasmapheresis/IVIg protocol for alloantibody desensitization in
1998. In 2001, Dr. Ratner orchestrated the second paired-kidney
exchange in the U.S. Subsequently, he arranged the first paired
kidney exchanges in both Pennsylvania and New York. More recently
Dr. Ratner has been a leading proponent of including compatible
donor/recipient pairs in kidney exchanges. All of these
strategies have increased organ availability and access to transplantation.
Additionally, he has made important contributions to
improve living donor safety. For his work, Dr. Ratner has received
numerous awards and honors. And, he has been invited to speak
and operate at various venues around the world.

Dr. Ratner has authored or co-authored over 180 peer-reviewed
publications, and has been a federally funded investigator. His
publications have been cited over 12,000 times. He served as
the Chairman of the Board of Directors of the LiveOnNY (formerly
the New York Organ Donor Network), and has served on
numerous national committees including the Board of the United
Network for Organ Sharing. He was elected Treasurer of the
American Society of Transplant Surgeons, and presently serves
as that Society’s President-Elect.

undergraduate education at the State University of New York at
Buffalo. He received his M.D. from Hahnemann University. His
