Dr. Pittendrigh’s program spans the areas of structural and functional genomics of insect toxicology, population genetics of pest populations, international development, integrated pest management, and high throughput delivery systems for outreach/extension.  He works on a diversity of insect systems including Drosophila, human lice (he directed the body louse genome sequencing/annotation project), and pest species of cowpea. Prior to becoming an MSU Foundation Professor (2016-present), he held the C.W. Kerns, C.L. Metcalf and W.P. Flint Endowed Chair in Insect Toxicology position (2008-2016) at the University of Illinois at Urbana Champaign).  He is also the co-founder and co-director of Scientific Animations Without Borders (SAWBO).  The online SAWBO platform can be found at and video library can be found at

Program Description


Dr. Pittendrigh has taught a diversity of courses ranging from host plant resistance, to introductory genetics, pesticide toxicology, and international development.


The Pittendrigh laboratory has multiple research themes.  First, we use genomic, proteomic and metabolomic approaches to understand induced responses to xenobiotic exposure and the evolution of the molecular mechanisms of insecticide resistance.  Most of this work has occurred through the use of Drosophila melanogaster as a model system.  Second, we have been heavily involved in the structural and functional genomics of head and body lice, while providing both a leadership role in the sequencing of the body louse genome and a collaborative involvement in developing reverse genetic tools that have been applied to elucidate important biological questions in this system.  Third, we have played a leadership role in a decade long (five country) collaborative program to develop pest controls strategies for cowpea pests within a West African context.


Dr. Pittendrigh’s extension/outreach program is focused on virtual communities of practice and high throughput strategies for (1) taking expert knowledge and placing it into a format that is understandable by individuals of all literacy levels and of diverse language backgrounds and (2) making it highly accessible to those that deploy such content.
