Biography

Dr. A. Mark Cigan, PhD

Dr. Cigan is the Trait Development Director at Genus R&D. Through internal and external collaborations, Mark leads research teams which use gene editing, gene sequencing and mammalian cell and reproductive biology to discover and develop disease resistance traits to improve animal health in livestock.

Prior to joining Genus in 2016, Mark was at DuPont Pioneer (now Corteva Ag) for 24 years focusing early in his career on plant reproductive biology to develop genetic solutions for the generation of hybrid seed. Upon completion of the Pioneer Seed Production Technology process, as Senior Research Manager, Mark then led the Genome Modification group at Pioneer (now Corteva Ag). The group was seminal in advancing editing and insertion of plant genes for commercial applications in maize, sorghum, wheat and soybean to speed trait development and deployment.

Mark has authored more than 40 science publications, and enjoyed professional collaborations with US, European and Australian laboratories focusing on aspects of genetics, plant reproductive biology and genome modification. Mark is an inventor on over 30 US and International granted patents and has served on the Maize Genetics Steering Committee and an invited speaker at plant and animal conferences.

After earning his doctoral degree in Yeast Genetics and Molecular Biology at Northwestern University, Chicago, Mark extended his graduate studies as a National Research Council Fellow at the NIH in Bethesda, Maryland. Working in yeast as a model, his biochemical work contributed to the understanding of how eukaryotic cells control protein synthesis of genes under stress.
