New Faculty

Dr. Beverley Carter

Laboratory services, Faculty of Medicine

Dr. Beverley Carter has joined the Faculty of Medicine in a new position as both a full-time faculty member and the provincial director of Pathology and Laboratory Medicine with the Department of Health and Community Services. The position was created in line with a recommendation from the Cameron Inquiry to have someone oversee pathology in the province from the recruitment and retention of staff to patient safety and including accreditation for all laboratories in the province. Dr. Carter will act as an advisor to the minister of Health and Community Services on matters related to pathology and laboratory medicine.


Dr. Carter received her MD from Memorial in 1989 and went on to do a rotating internship and one year of obstetrics and gynecology at Dalhousie University.

She then switched specialties and did a residency in general pathology at McMaster, followed by a residency in anatomic pathology at McMaster.


Dr. Carter did a fellowship in breast pathology and molecular techniques from 1998-99 at Vanderbilt University, Nashville. Following this she worked until 2003 with the Hamilton Regional Laboratory Medicine Program as a staff member in anatomic pathology, also serving as a consultant oncologic pathologist for Cancer Care Ontario and as a consultant breast pathologist for Pathology Associates in Hamilton. She also held a position as an assistant professor in the Department of Pathology and Molecular Medicine, Faculty of Health Sciences, McMaster University.


From 2004-2009 Dr. Carter was a staff physician in anatomic pathology at St. Clare’s Mercy Hospital and an assistant professor of pathology in the Faculty of Medicine at Memorial. From 2006-2007 she was director of the Quality Management Program for pathology with the St. John’s hospitals of Eastern Health. In 2008 Dr. Carter moved to British Columbia where she was a consultant oncologic pathologist and breast pathologist with the BC Cancer Agency. In 2009 she took on the position as director of Quality Management and medical director of anatomic pathology with the BC Cancer Agency.


Dr. Lourdes Peña-Castillo

Departments of Computer Science and Biology

Dr. Lourdes Peña-Castillo holds a bachelor of information systems engineering from Mexico’s Technological Institute of Monterrey, and a M.Sc. and PhD in Computer Science from the University of Alberta and Otto-von-Guericke Universität Magdeburg in Germany, respectively.

She followed her studies with a post-doctoral fellowship at the University of Toronto's Banting and Best Department of Medical Research and a position as a research associate at the National Research Council of Canada’s Institute for Information Technology.

Upon beginning her employment as an assistant professor jointly appointed between the departments of Computer Science and Biology on July 1, 2010, Dr. Peña-Castillo brought a new area of expertise to Memorial University.

“Bioinformatics is the application and development of computer science resources – software, databases, algorithms and analysis approaches – for solving biological problems,” she explains.

“I focus mostly on genomics, which is concerned with genes' functions, and genetic variations and their impact. Large scale biological experiments produce thousands of data points and you need computers to analyze that data.”

Her research puts her in close collaboration with researchers from computer science, biology, biochemistry and medicine. She is currently developing bioinformatics courses using an interdisciplinary approach that, starting in fall 2011, will see students from computer science and biology together in the same classroom.

“The interdisciplinary approach for bioinformatics is so important the students need to start early to learn to collaborate with people in the other fields that converge in bioinformatics.”


Dr. Bayan Missaghi

Infectious Diseases Division Faculty of Medicine

In addition to his faculty position, Dr. Bayan Missaghi is medical director of Eastern Health’s HIV Clinic, which provides service to the whole province, and chair of the Antimicrobial Stewardship Committee.

He received his MD in 2005 from the University of Saskatchewan’s College of Medicine and did an internal medicine residency at the Maine Medical Center from 2005 to 2008. He spent the next two years at the same institution doing a Fellowship in infectious diseases. During this Fellowship his clinical experiences included inpatient adult and pediatric infectious diseases consultation, outpatient general infectious disease and travel clinics, outpatient HIV clinics, outpatient hepatitis clinics, microbiology and antimicrobial stewardship rotations and hospital epidemiology experiences.

Research experience during his Fellowship gave Dr. Missaghi expertise in diagnostic and therapeutic approaches to Clostridium difficile infection which resulted in an extensive review article published in Current Infectious Disease Reports and a poster presententation at the Fourth International Symposium on Resistant Gram-Positive Infections. The Fellowship also provided education and training on the design and conduct of a variety of study types, writing informed consents, approaching Institutional Review Boards, implementing and managing projects and developing clinical and laboratory research skills.

Dr. Missaghi’s current primary research interests revolve around the utility of anal PAP testing in HIV positive homosexual men in addition to antimicrobial stewardship research and collaborative efforts.


Dr. Alexander Mathieson

Discipline of Surgery, Faculty of Medicine

Dr. Alexander Mathieson earned his MD at Memorial in 2001 and did a residency in general surgery at Memorial from 2001-2007.

Dr. Mathieson has a broad interest in general surgical oncology with a main focus on breast and gastrointestinal malignancy. He is a member of the General Surgery Residency Committee in the Faculty of Medicine.

His current research interests include the use of adjuvant therapy in elderly patients with colorectal cancer; the impact of isolated tumour cells in lymph nodes on outcomes in breast cancer; and resection of retroperitoneal recurrences of colorectal cancer. He is first author on a number of research publications, most recently a case control study on the use of adjuvant chemotherapy in elderly colorectal cancer patients, presented at Canadian Surgical Forum in September 2010.
