Professor Nick Di Girolamo is a research-focused academic leading an internationally recognised group whose mission is to restore sight in patients blinded from severe corneal disease. His expertise is the mammalian corneal, understanding how it develops and heals, and the diseases that develop when its stem cell reserves are depleted. His research program integrates basic sciences, revolutionary animal models, cutting-edge intravital imaging, novel image analysis modalities and world-first clinical trials using adult stem cells; the results of which have demonstrated improved eye health and vision in patients. Nick has received two decades of continuous funding from the NHMRC and other national and international funding agencies and has over 120 peer reviewed published articles.

My Research Activities

Corneal stem cell transplantation

One arm of our research program involves identifying, isolating and cultivating human and murine corneal epithelial stem cells. We believe this accomplishment will help us understand how the ocular surface is replenished and maintained in a healthy transparent state under normal physiological conditions and following trauma. Identifying markers for these rare but important cell is key, and to this end, we are performing cutting-edge single cell RNA sequencing experiments with appropriate analyses whilst conducting validation studies. We also hope to also identify better culture conditions and better carrier-scaffolds for these cells because the aim is to generate better quality, more effective stem cell grafts to treat patients with severe corneal diseases that result in blindness.


Developing diagnostic tools for patients with corneal disease

Another area we are interested in pursuing is to develop minimally invasive diagnostic and prognostic in-office tests for patients with corneal diseases. Here, we have focus on corneal nerves because we believe their features (e.g., density, length, thickness, branching, etc) will provide valuable ‘structural’ information about local (corneal) and systemic (whole body) health. To this end, we have developed an image segmentation algorithm for the auto-detection and computation of corneal nerve characteristics in the mouse and are poised to develop and measure the same nerve parameters using Machine Learning using clinical in vivo confocal microscopy images from patients.


Corneal Wound Healing

The third arm of our research program focuses on understanding the mechanisms of wound-healing in the cornea and to devise better therapies to treat patients with persistent corneal epithelial defects. Patients with such conditions do not require a cell or tissue replacement strategy so we are searching for corneal wound healing factors that can be dispensed to accelerate re-epithelialisation, thereby preventing infection and other complications. Notably, we have also identified uncommon and unreported non-tumourgenic transformation phenomena on the corneal surface, some of which are pathological and some that might be physiological, i.e., attempt to self-resolve. Our goal is to characterise these curiosities and potentially reverse them if they are pathological or indeed encourage them if they partake in regeneration. These investigations are carried out using pre-clinical animal models.


Dry Eye Disease

The fourth arm of our research program focuses on developing clinically relevant animal models of dry eye disease to understanding how this disease evolves, the ocular surface cell types involved in its pathogenesis and importantly developing treatment options that can be used on patients with this condition.
