Familiar Faces Take On New Roles

Steven Rosalie

Normally a time for rest and relaxation, the summer has been bustling with activity as Dr. Antonio Gotto Jr., the Stephen and Suzanne Weiss Dean of Weill Cornell Medical College, has announced the appointments of four administrators to new posts, reflecting the College's thriving partnerships and growing international scope. The executives assuming new roles are Mr. Steven Rosalie, Dr. Dirk Sostman, Dr. E. Darracott Vaughan, and Dr. Daniel Knowles. 


A senior administrator at Weill Cornell for the past 12 years, Steven Rosalie has been named as associate provost for international initiatives and executive vice dean, a newly created position. Mr. Rosalie previously served as Weill Cornell's executive vice dean and associate provost for operations, a position the Medical College will fill through a national search.

"This new position is testament to Weill Cornell's dedication to building a transnational presence in research, education, and clinical care," Dean Gotto said. "Steve Rosalie's appointment ensures that our international initiatives will thrive and our international agenda will expand, propelled by our vision for new levels of excellence in global health care."

Dr. E. Darracott Vaughan

Dr. E. Darracott Vaughan is appointed senior associate dean for clinical affairs.


In his new position, Mr. Rosalie will serve as the College's senior administrative official to oversee the international programs and initiatives involving both existing and new relationships entered into by Weill Cornell Medical College and Graduate School of Medical Sciences. In its rapidly developing international agenda, the College has already entered into six international affiliations and agreements with institutions in Qatar, Turkey, Germany, South Korea, Brazil and the Philippines – establishing educational, research, and clinical relationships that benefit both Weill Cornell and its partners.

Furthering the College's reach here at home, Dean Gotto has named Dr. Dirk Sostman, formerly senior associate dean for clinical affairs and executive vice dean, and chairman of radiology at the Medical College, to the position of chief academic officer and chief medical officer at The Methodist Hospital System in Houston. In his new role, Dr. Sostman will spearhead the partnership between Weill Cornell, NewYork-Presbyterian, and The Methodist Hospital, while helping to implement many new initiatives in quality, research, clinical care, and academics. Dr. Sostman remains an executive vice dean and professor of radiology at the Medical College.

"We express out utmost gratitude to Dr. Sostman for his leadership and dedication," said Dean Gotto. "We are fortunate to be keeping him in the family as he brings his assets to The Methodist Hospital, one of our newest clinical and research affiliates."

Dr. Robert Min has assumed Dr. Sostman's duties as acting chairman of radiology at the Medical College and acting radiologist-in-chief at NewYork-Presbyterian/Weill Cornell. (Click here to read about Dr. Min's appointment.)

Building upon Dr. Sostman's legacy will be Dr. E. Darracott Vaughan, who has been appointed the new senior associate dean for clinical affairs for the Medical College.

Dr. Daniel Knowles

Dr. Daniel Knowles has been named chief medical officer of the Physician Organization.

The former chief medical officer of the Weill Cornell Physician Organization, and chairman of the Medical College's urology department from 1978 to 2001, Dr. Vaughan, the James J. Colt Professor of Urology, will oversee all matters relating to clinical organization and patient care. He will also serve as chief liaison among the clinical faculty, Physician Organization, and Dean Gotto.

"Dr. Vaughan's track record of accomplished leadership, along with his thorough familiarity with the Physician Organization, render him superbly qualified to serve as dean for clinical affairs," said Dr. Gotto. "We are certain his vision and dedication will prove equally fruitful in this new capacity as they have in his nearly 30 years at the Medical College."

Assuming Dr. Vaughan's former role as chief medical officer of the Weill Cornell Physician Organization is Dr. Daniel Knowles, the David. D. Thompson Professor and chairman of the Department of Pathology and Laboratory Medicine at the Medical College, as well as pathologist-in-chief at NewYork-Presbyterian Hospital/Weill Cornell Medical Center.

"We are so pleased to name Dr. Knowles as the chief medical officer of our Physician Organization," said Dr. Gotto. "This position is key to the smooth operation of our clinical practices, lending critical support to our faculty and therefore our community."

Established by Cornell University for the management of the faculty's clinical practices, the Weill Cornell Physician Organization (PO) is dedicated to the advancement of medical science and education, as well as the delivery of excellent patient care.

"I am grateful to be afforded the opportunity to lead the Physician Organization at such an exciting time," Dr. Knowles said. "I am looking forward to working with the PO management team assembled by Dr. Vaughan and with all the clinical department chairs to facilitate our clinical mission."
