Welcome to the Lazzaro Lab at Cornell University! Our work is focused on the evolutionary genetics of insect-pathogen interactions. Our projects include population genomic and molecular evolutionary analysis of insect immune systems and quantitative genetic study of differences in immune performance among individuals in a population. We seek to identify the genes responsible for individual differences in resistance or susceptibility to infection and environmental factors that influence defense. We are determining how genotype and environment interact to determine defense traits, and how seemingly distinct physiological processes are genetically linked and may constrain each other. At the same time, we note that the host is itself the "habitat" in which the pathogen lives and grows. We would like to understand how pathogens achieve infection of the host, and how host genotype and environment shape infection kinetics from the perspective of the pathogen. Our overarching goal is to consider host and pathogen as interacting components of a single system, shaped by the environment, that ultimately determines the outcome of infection and disease.

EEID 2016 Registration Now Open

Registration is now open for this year's Ecology and Evolution of Infectious Disease (EEID) conference, to be held at Cornell June 3-5. This is an excellent conference that emphasizes disease evolution and epidemiology in natural systems. We will be making a special point to emphasize both theoretical and empirical work in plant and animal systems.

There will be four primary themes for the meeting:
1) Polymicrobial Infection and Disease
2) Pathogen Dynamics within the Host
3) Pathogen Genomics, Evolution, and Selective Constraints
4) Disease Outbreaks on the Landscape Scale

More details here. We hope to see you at Cornell in June for EEID!
