Lead by Dr. Keijzer, MD, MSc, PhD, FACS
Dr. Keijzer was born and raised in The Netherlands. He did his clinical training (General Surgery and Pediatric Surgery) at ErasmusMC-Sophia in Rotterdam, The Netherlands and a fellowship in Pediatric Endoscopic Surgery at The Children’s Hospital of Alabama in Birmingham, Alabama. His research training consisted of MSc and Ph.D. degrees at the Departments of Pediatric Surgery and Cell Biology & Genetics of ErasmusMC in Rotterdam and the Department of Lung Biology Research in the Hospital for Sick Children in Toronto. After completion of his General Surgery training, he did a postdoctoral fellowship at the Department of Physiology & Experimental Medicine of the Hospital for Sick Children in Toronto.
In 2010 he joined the Department of Surgery at the University of Manitoba and the Children's Hospital Research Institute of Manitoba as a pediatric surgeon-scientist. His clinical interest concentrates on minimal invasive Pediatric General Surgery. He has established a research program in normal and abnormal lung development related to congenital diaphragmatic hernia (CDH). His ultimate research goal is to develop a prenatal therapeutic intervention to modulate the natural course of the abnormal lung development in CDH and improve the outcome of babies born with this anomaly.
Dr. Keijzer was awarded a Career Development Award from the Canadian Child Health Clinician Scientist Program in 2012 and was named the inaugural Dr. Paul H.T. Thorlakson Chair in Surgical Research and Director of Research for the Department of Surgery in July 2012.

Dr. Andrew Tse, PhD
Dr. Andrew (Wai Hei) Tse obtained his Bachelors of Medical Science (Honours) and Doctor of Philosophy at the University of Western Ontario in London, Ontario in the field of Medical Biophysics. Trained under the guidance of Dr. Jin Zhang in biomedical and chemical engineering, Andrew honed his research focus on the design, modification, and application of nanoparticles for clinical practice. He aspires to apply a theranostic approach, a combination of diagnostics and therapeutics, using nanoparticles to act as a therapeutic chauffeur for clinical application. For his endeavours and contributions he was awarded an NSERC Postgraduate Scholarship (Doctoral) and Western's Doctoral Excellence Research Award (DERA). In 2017, he joined the miRacla Lab as a postdoctoral fellow. He is currently investigating potential methods of drug delivery to administer microRNAs (miR), in particular, miR-200b as a potential therapeutic option using nanoparticles to rescue abnormal fetal lung development in CDH. The objective is to deliver a nanoparticle construct laden with miR-200b via transplacental transmission to selectively target and rescue lung hypoplasia while minimizing maternal exposure. Furthermore, Andrew is currently exploring prospective proponents of CDH in the established nitrofen model. In particular, he is interested in the environmental triggers affecting the pathogenesis of CDH and their relationship with the onset of lung hypoplasia.

Dustin joined the miRacla lab in August 2015, before entering his final year at the University of Winnipeg and beginning work on his Honours Project. The goal was to study the differential expression of proteins between wildtype and miR-200b knockout mouse lungs, particularly those involved in epithelial-to-mesencyhmal transition (EMT). Since then, he has been investigating the mechanisms behind pulmonary miR-200b downregulation in fetal rats that have nitrofen-induced diaphragmatic hernias. The idea is that production of mature miR-200b is disrupted during its biogenesis, and the hope is to link any findings to dysregulation of miR-200b in human congenital diaphragmatic hernia. In his spare time, Dustin does rock climbing and skate skiing, but mostly eats.
