Carolina Lopez-Uran, MD


Chief of Pathology

Pathologist, Dr. Lopez Uran is currently an Assistant Professor of Pathology Department, Faculty of Medicine at the University of Antioguia, Colombia. Dr. Lopez-Uran obtained her MD at the Bolivariana University in 2000, specialty in Pathology at the University of Antioquia, Medellin, Colombia in 2006 followed by extended training in Oncologic Pathology at the National Institute of Oncology in Bogota.

In May 2013 she joined Dr. Done's lab where she was involved in investigation of SPAG5 gene expression as a molecular marker for breast cancer prognosis and others projects related to better understanding of breast cancer intratumoural heterogeneity. Upon completion of sabbatical, Dr. Lopez-Uran returned to Colombia where she has mainly focused in setting up molecular pathology tests and breast cancer research projects within Colombian population.

Lucia Kim, MD, PhD


Associate Professor & Staff Pathologist

Dr. Kim graduated from Yonsei University College of Medicine in 1996; and in 2001 had completed pathology residency at Yonsei University Hospital followed by PhD (2004). Currently, she is a Surgical Pathologist and an Associate Professor at the Department of Pathology at the Inha University School of Medicine.

At the end of February 2012, she joined Dr. Tsao laboratory where she focused her interests in identification of molecular subsets of lung cancer.


Sonja Steigen, MD, PhD

Professor & Staff Pathologist

Dr. Steigen primary interest is in Gastrointestinal Stromal Tumors (GIST). Her research has been mostly at an epidemiologic level to date, but now in conjunction with the CIHR/MOTP is combining clinical data with molecular biology, using tissue microarrays and DHPLC/PCR as the main tools.

Her fellowship commenced in September 2003 at the University of Tromsoe, Department of Morphology. She joined Dr. Nielsen`s lab at the Genetic Pathology Evaluation Centre in Vancouver in August 2005 and completed in June 2006. The two main projects she was involved were:

 1) Classification of mesenchymal tumors from the digestive tract through immunohistochemical techniques on tissue microarrays built from small cores of the samples, using the facilities in place at the Genetic Pathology Evaluation Centre.

 2) Mutation analysis of GIST; in collaboration with the BCCA diagnostic lab. Clinically applicable methodologies to assess GIST mutation status will be developed using Norwegian and Canadian specimens. 

Dr. Steigen returned to Norway where she is a Fellow and Consultant Pathologist at the same institute.  She will continue her collaboration with Dr. Nielsen at the BCCA laboratories.

Gilda da Cunha Santos, MD, PhD, FRCPC

Associate Professor, Department of Laboratory Medicine and Pathobiology

Dr. Santos is a well-established histopathologist/cytopathologist and an Associate Professor of Pathology at the Federal University of Sao Paulo (UNIFESP). She has completed a 3-year residency training program in anatomic pathology at the School of Medicine of Botucatu in Brazil. In 1995 she received a Ph.D. degree in Human Pathology. Dr. Santos has come with a wealth of experience in all aspects of cytopahology with emphasis on head and neck and breast lesions. Furthermore she completed fellowship training in fine-needle aspiration cytology at the Karolinska Hospital in Stockholm. In October 2004 she joined Dr. Squire’s lab where she has acquired advanced molecular training in cytogenetics. Her training was completed in December 2005.

In December 2006, she has assumed a faculty position as a Pathologist and Associate Professor at the University Health Network and University of Toronto. 


 Young-Ha Oh, MD

Associate Professor, Department of Pathology

Dr. Young-Ha Oh is a board certified pathologist in Korea and her subspecialty is hematopathology. She graduated from medical school at the Hanyang University in Seoul, Korea and completed a 4-year-residency and 1-year fellowship programs in Surgical Pathology at the same institution. She has been working for Hanyang Medical Centre and also appointed as an Associate Professor of the Department of Pathology at Hanyang University College of Medicine in Korea since completing her training course. She decided to broaden her research experience and knowledge on Lymphoma/Myeloma Biology and Pathophysiology. She joined Dr. Gascoyne’s lab at the British Columbia Cancer Agency in Vancouver in September 2006. During her one-year subbatical, she has focused on two main projects:

 1) The Cytogenetic Differences and Gene Expression Profiling Between PET-positive and -negative Diffuse Large B Cell Lymphomas.

 2) NOTCH2 Mutations in Marginal Zone Lymphomas

Dr. Oh returned to South Korea and is working at Hayang Medical Centre.


Kyu Sang Song, MD, PhD


Staff Pathologist

Dr. Song is a well established Surgical Pathologist and a Professor of Pathology in South Korea.  He graduated from College of Medicine at Chungnam National University in Daejeon City.  He received his MD and PhD degrees at the same institution and did anatomic pathology residency training in the Chungnam National University Hospital.  After finishing his training course he has been working as Staff Pathologist at the same same hospital since 1986 and appointed as a Professor in 1997.  He decided to broaden his knowledge on molecular pathology during 1-year sabbatical at Dr. Tsao's laboratory to focus his research activities on molecular profiling of various cancer cells.  His sabbatical training was completed in February 2009.


Yeonsook Moon, MD, MSc, PhD


Staff Pathologist
