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 shape defense traits, and how seemingly distinct physiological processes are genetically linked and may constrain each other. We are especially interested in the effects of dietary nutrition and metabolism, gut microbiological communities, and reproductive status on immune performance. We use molecular tools and genomic analysis in our research. Read more at our Research page.

Sarah K. at Evolution 2014


Sarah Khalil is representing the lab in Raleigh at the annual meeting of the Society for the Study of Evolution. Sarah was the recipient of an Undergraduate Travel Award from the conference organizers, and is presenting a poster on her work with Moria, "Effect of chronic Providencia rettgeri infection Drosophila melanogaster resource allocation." Have a great time, Sarah, and the rest of the lab looks forward hearing you report back on what is new and cool in evolutionary biology.
