Dr. Lydia Lynch
Associate Professor in Immunology, Biochemistry


My lab is interested in understanding the cross-talk between the innate immune system and the metabolic system, and the key molecules involved. A major focus is to understand the cellular metabolic decisions controlling the effector fate of leukocytes that may ultimately open doors to manipulate the immune system in metabolic disorders. This also extends to other situations of altered metabolism, such as in the tumor microenvironment. The goal is to integrate the two aspects of immunometabolism (systemic and intrinsic bioenergetics) to enable us to find metabolic targets for immune cell modulation and ultimately manipulate them in human disease.
