Stefan Hofer

We are delighted to welcome Stefan Hofer to the Division of Plastic Surgery at the University Health Network (UHN). Dr. Stefan Hofer is the Division Head, Plastic Surgery at UHN and the second Wharton Chair in Head and Neck Reconstruction. He is appointed as an Associate Professor and Surgeon-Investigator and is the Division's first international candidate to be recruited in over a decade.

Dr. Hofer obtained his medical degree from the University of Amsterdam in 1992. He then completed his PhD studying tissue oxygen tension as an indicator of tissue perfusion with Prof. Dr. P.J. Klopper, Department of Surgical Research, Academic Medical Center, Amsterdam. Stefan then obtained his board certification in Plastic Surgery from the Netherlands in 2000. Prior to moving to Toronto, Dr. Hofer was a Staff Plastic Surgeon in the Department of Plastic and Reconstructive Surgery, Erasmus Medical Center, Rotterdam and the Head of Plastic and Reconstructive Surgical Oncology.

Stefan is an accomplished plastic and reconstructive surgeon and has a strong international reputation for his outstanding contributions in the areas of clinical service, education, and research. Dr. Hofer's clinical interest is in head & neck and breast oncologic reconstructive surgery. Dr. Hofer will focus on technical improvements of reconstructive techniques, and functional and aesthetic outcomes after reconstructive surgery. Stefan's research is in angiogenesis and tissue engineering, more specifically the vascularization of three-dimensional tissue engineered constructs.

Dr. Hofer's practice will be based out of his office at the Toronto General Hospital. Stefan is actively recruiting to the Division of Plastic Surgery - with his eye on building Canada's largest oncology reconstructive program.

We welcome Stefan, his wife Jenny and his children Lisa and Daniel to Toronto, UHN, the Department of Surgery and the Division of Plastic Surgery.

Markku Nousiainen
Markku Nousiainen, recently appointed to the staff of the Holland Orthopaedic & Arthritic Centre - SHSC, graduated from Queen's University at Kingston with an Honours Bachelor of Arts Degree in 1993. He then completed a Master of Science in Biology at the University of North Carolina at Charlotte in 1995 and obtained his M.D. at the University of Toronto in 2000. His residency training in orthopaedic surgery was also at the University of Toronto; he graduated in 2005.

Dr. Nousiainen has performed two fellowships, one in adult lower extremity reconstruction with Drs. Alan Gross and David Backstein at Mount Sinai Hospital in Toronto, and the other in orthopaedic trauma with Dr. David Helfet at the Hospital for Special Surgery in New York, NY. He is currently completing a Master of Education degree at the Ontario Institute of Studies in Education, University of Toronto, specializing in Health Professions Education.

Dr. Nousiainen's clinical interests lie in adult trauma (pelvic, acetabular, periarticular fractures) and reconstruction (primary and revision total hip and knee arthroplasty). His research interests involve training policy in fellowship-level education and in surgical skills education (particularly involving computer navigation) at the novice and expert levels.

Mark Peterson

It is a pleasure to announce the recruitment of Dr. Mark Peterson as a cardiac surgeon/investigator to our group. Dr. Peterson has completed his MD at the University of Manitoba and had his full cardiac surgical residency training here at the University of Toronto as well has his PhD. He completed his post training fellowship in endovascular surgery where he worked at the Arizona Heart Institute under Dr. Ted Diethrich. He has had funding from the Heart and Stoke Foundation and the CIHR as well as PSI grants. His special interest in large vessel stenting will be in concert with the vascular surgeons and diagnostic imaging. (See related article here)

John Theodoropoulos
John completed his medical school at Queen's University and orthopaedic residency at McGill University, during which he did an elective at Mount Sinai. He completed a sports fellowship at the University of Illinois Chicago. Since then he has been in practice at William Osler Hospital. He feels that the future of sports medicine is in developing better biologic based repair therapies (e.g. tissue engineering or cartilage regeneration), and would be interested in working with a team to develop novel therapies. He also has a strong interest in teaching residents, and has an interest in using the skills lab to help develop techniques to teach the residents how to do arthroscopy. He has a real interest in working as part of a translational research team to develop novel therapies for sports related research. John is our first orthopaedic recruit into the new Women's College Hospital.
