To effectively improve the way we treat a tumor, we must first elevate our understanding of the tumor. To do so, it is essential to gather and incorporate information at the molecular level.  Accordingly, I aim to identify new molecular drivers in aggressive pediatric brain tumors and to ultimately translate my findings into therapeutic targets.

Tlais Research Summary

High-grade gliomas are rapidly growing brain tumors that are generally resistant to standard therapeutic approaches. To introduce new treatment strategies, my aim is to understand the molecular characteristics of these tumors.

One focus of mine is pediatric diffuse hemispheric glioma (DHG), H3G34-mutant, a recently molecularly characterized and classified pediatric brain tumor. In collaboration with Dr. Jason Chiang, Dr. Asim Bag, and Dr. Christopher Tinkle, I am working on characterizing and understanding the clinical, radiographic and molecular characteristics of this tumor type with the goal of introducing new therapies.

Additionally, in collaboration with Dr. Suzanne Baker and Dr. Giles Robinson, I am exploring novel ways to target molecular vulnerabilities in diffuse midline glioma, H3K27-altered, and aiming to launch a clinical trial tailored towards patients with these tumors.

Beyond research in molecular vulnerabilities in high-grade gliomas, I have a specific interest in the use of immunotherapy in pediatric brain tumors.  To this end, I am collaborating with Dr. Bertrand in her work in CAR T-cell therapy through the Loc3CAR clinical trial, and we are looking forward to the promising future of immunotherapy in neuro-oncology.
