Research and Practice Interests

In my research, I pursue topics such as regulation of inflammation, dendritic cell biology, innate immunity, toll-like receptor signaling and the cross-talk between the innate and adaptive immune systems. Our lab’s primary goals are to understand how the innate and adaptive immune system interact with each other and to define the molecules that are part of this interaction.

We are also studying how inflammation is prompted by microbial recognition and during autoimmunity. In general, our objectives are 1) to obtain a molecular understanding of inflammation to develop new treatments for reducing autoimmunity and inflammation and 2) to define the complex communication between innate and adaptive immune systems in order to improve the design of vaccines.
Some of the most notable discoveries my colleagues and I have made include:

  • Discovering a completely new pathway for inflammation in which auto-reactive T cells guide the innate immune system to produce IL-1beta; the new pathway may be used to treat auto-immunity
  • Finding a new Toll-Like Receptor signaling adapter known as BCAP that reduces inflammation
My lab concentrates on identifying the innate immune system's main activation mechanisms and its effect on inflammation and adaptive immunity. The innate immune system depends on certain receptors known as pattern recognition receptors to distinguish pathogens.

Pathogen recognition via the innate immune system causes inflammation as well as adaptive immunity activation. One of my lab's major objectives is to identify the elaborate interaction and signaling between the innate and adaptive immune systems. My colleagues and I are specifically pursuing how the innate immune system prompts inflammation and how it affects both protective immunity and inflammatory conditions.

My research interests began due to my fascination with learning how the body’s immune system knows not to react to self but recognizes and responds to the microbial non-self. Our research has defined multiple new proteins and pathways in cells within innate and adaptive immune systems. We have utilized them as handles to direct questions regarding protective immunity, cancer and inflammatory diseases. We employ cutting-edge in vitro and in vivo methods in our research that may bring new targets to treat auto-immunity, cancer and inflammatory conditions.
