Welcome to the Wood Laboratory at MD Anderson Cancer Center. Research in our group explores the mechanisms of genome stability and the consequences for cancer, including the biochemical mechanism of repair of cross-links between DNA strands and the DNA polymerases that help cells tolerate DNA damage.
It is important to understand the mechanisms of DNA repair in detail, because this process is a front-line defense against the mutations that cause cancer. Mammalian cells have numerous strategies for repair of DNA damage and devote many hundreds of genes and proteins to DNA repair. Moreover, the aim of many cancer therapies is to disable tumor DNA by using DNA-damaging radiation and drugs. Research in the Wood Lab employs a broad range of investigations, ranging from fundamental biochemical studies and proteomics through cellular biology, to genetically engineered mouse models having impaired pathways of repair and mutagenesis.

Rick Wood, Ph.D., is the winner of the 2021 Environmental Mutagenesis and Genomics Society Award, which recognizes outstanding research contributions in the areas of environmental mutagenesis and genomics.
Welcome to postdoctoral fellow Mélanie Prodhomme, Ph.D., who joined us at the end of April from the Centre de Recherche en Cancérologie de Lyon (CRCL).
Congratulations to Sara Martin, Ph.D., who defended her dissertation in November and has now had her thesis work published in Cell Reports, 2021. Dr. Martin is currently a postdoctoral fellow at Tufts University in Medford, MA, where she was selected as an IRACDA (Institutional Research and Academic Career Development) scholar in May.
The lab welcomes postdoctoral fellow Yuzhen Li, Ph.D., who recently received her PhD degree from Tsinghua University in China. She joins postdoc Denisse Carvajal, Ph.D. from St. Louis University who joined the lab in 2018.
The Wood lab continues to collaborate with former lab colleagues Kei-ichi Takata, who now leads a laboratory at the Institute for Basic Science, Center for Genomic Integrity, Ulsan National Institute of Science and Technology in Ulsan, S. Korea, and Junya Tomida, Assistant Professor at the University of North Carolina at Charlotte.
Rick Wood, Ph.D., was elected to the American Academy of Arts and Sciences in 2018. Congratulations, Rick!
We are pleased to have research support from the National Institutes of Health and the Department of Defense.
