About
Welcome to the Avila Lab! Our lab leads the research program in long-term outcomes of paediatric thrombosis at The Hospital for Sick Children (SickKids), with a focus on post-thrombotic syndrome (PTS).
Dr. Laura Avila is a Clinician Scientist at SickKids. During her training in Paediatric Haemostasis and Thrombosis at SickKids, she developed a special interest in paediatric PTS. During her PhD in Clinical Epidemiology at the University of Toronto, she conducted a series of studies that led to the development of CAPTSure©, a tool for the diagnosis and severity rating of this condition in children. Subsequent work focused on the impact and management of paediatric PTS and the long-term outcomes of pulmonary embolism. Her clinical epidemiology work is focused on measurement in medicine, observational studies, and longitudinal studies.

Student opportunities
Summer programs
The SickKids Summer Research (SSuRe) Program offers university students the chance to engage in research within a laboratory or clinical environment at SickKids, guided by a scientist from the SickKids Research Institute for the summer.
The Institute of Medical Science’s (IMS) Summer Undergraduate Research Program (SURP) provides a unique opportunity for undergraduate B.Sc. and medical students (without a graduate degree) to participate in biomedical research projects. These projects cover a wide range of disciplines, including molecular biology, cognitive science, clinical investigation, and bioethics. This summer research program concludes with Research Day in mid-August where students are given the opportunity to showcase their research findings through oral or poster presentations.
Graduate student programs
Dr. Avila is welcoming M.Sc. and PhD students via the Institute of Health Policy, Management and Evaluation, as well as the Institute of Medical Science at the University of Toronto, with a research focus on thrombosis.
