Biography

Dr. Ungrin is a transdisciplinary researcher whose work focuses on the efficient translation of biomedical research into societal impact, integrating basic science, technology development, and the importance of research integrity and reproducibility. 

An Associate Professor at the University of Calgary, he is affiliated with the Department of Biomedical Engineering, the Alberta Children’s Hospital Research Institute, and his home Faculty of Veterinary Medicine. He completed his undergraduate degree in Biochemistry, and worked in the pharmaceutical industry before obtaining his Ph.D. in Cellular and Molecular Biology at the University of Toronto’s Department of Medical Biophysics, followed by post-doctoral research in the Institute for Biomaterials and Biomedical Engineering.

His work has been funded by all three of Canada’s Tri-Agencies, and he served on the Scientific Advisory Committee in the development of the GCCP2.0 standard for Good Cell and Tissue Culture Practices. His AggreWell technology (under license to StemCell Technologies, Inc. of Vancouver) is an international standard in organoid research, in use around the world and on the international space station.

Research

Areas of Research

Organoid engineering

The overall theme of my research program is the translation of biomedical research into positive societal impact. This includes the research itself, but also extends "down" the consilience ladder to the development of new tools, technologies and methods that support it; and "up" the ladder to issues of research rigour, reproducibility and integrity, management of risk in biological technology / biosafety / biosecurity, and the ways in which scientific understanding can be translated into impact.

My primary technical research focus is in the area of micro-tissue / organoid engineering – that is, tissue engineering on the sub-millimetre scale. Many groups around the world are working on producing various clinically useful cell types from stem and progenitor cells. The next major challenge is in assembling these cells into something useful, so they can be delivered to the patient to treat disease, or used in research labs as new model systems to study tissue behaviour. The injection of single cell suspensions into a patient has proved challenging, as many cells die, or end up in inappropriate locations. Engineered microtissues have many advantages, in that they are still small enough to be introduced through the bore of a needle – thus avoiding the need for major surgery – but the introduced cells come with their own supportive micro-environment, functional connections to their neighbours, and are not subjected to the trauma of dissociation.

We collaborate with a number of groups in a wide range of organoid and tissue types in both academia and industry, and of the projects that are currently public, it is our work in the area of diabetes that is likely closest to the human clinic. In addition, we are currently pursuing a novel strategy for intervention in orphan diseases, with funding from the NFRF, and exploring various applications of synthetic biology tools to tissue and organoid engineering.

Biomanufacturing and development of supporting technologies

Beyond development and study of the microtissues and organoids themselves, we are also developing the next generations of my AggreWell organoid engineering platform, and understanding how cell manufacturing processes can be adapted to make scalable production economically sustainable. As a research tool, it has already had a significant international impact and is now one of the standard approaches for the large scale production of uniform size- and composition-controlled organoids across tissue types in both academia and industry. Among other examples this notably includes both 2021 papers reporting groundbreaking models of the early human embryo, as well as the preceding mouse models reported in 2018/2019. Current efforts are focused on establishing and validating microtissue / organoid production at scale for clinical applications, to provide a bridge for the large existing user base to translate their bench-scale findings to pre-clinical and clinical trials. Members of the group have received various recognitions for this work, including being chosen for Mitacs' 2019 Outstanding Innovation Award (Doug Kondro, in the PhD category) and my own naming as a University of Calgary PEAK Scholar.

We also have an interest in the use of 3D printing and other prototyping technologies to develop simulated body parts for medical training applications and veterinary prosthetics.

Research quality and reproducibility

My group also has a long-term interest in research quality and reproducibility - critical factors for successful translation of any research to the human clinic - and the under-recognized role of basic factors such oxygen in introducing variability into culture systems (if you are working with cell culture in a context where oxygen levels are relevant, you should probably read this paper). This work has also been incorporated in the recently published Guidance document on Good Cell and Tissue Culture Practice 2.0 (GCCP 2.0), where I was a member of the Scientific Advisory Board.
