Research interests: The primary focus of my lab is the study of cell death, especially the natural cell death process known as apoptosis (programmed cell death), as well as unprogrammed cell death (necrosis). We are especially interested in how necrosis can promote activation of the immune system (i.e. promote inflammation), through release of IL-1 family cytokines (IL-1α, IL-1β, IL-18, IL-33, IL-36α, IL-36β, IL-36γ) and how apoptosis can also modulate inflammation.
Apoptosis is a mode of cell death that is under molecular control and can be triggered by a multitude of stimuli – both physiological as well as pathological. Cells die by apoptosis during development, tissue homeostasis, fine tuning of the immune system, and due to the normal wear and tear that multicellular organisms experience in everyday life. Apoptosis is also observed as a part of the damage-limitation response seen during infectious disease and is seen during many other pathological conditions, such as cancer and neurodegeneration. Understanding how and why cells die, at a molecular level, is leading to new insights into many fundamental biological processes as well as new ways of treating conditions where either too few (cancer, autoimmune disease) or too many (neurodegeneration) cells die.
