​Genomics Lab


The Genomics Lab is home to Forest Service researchers in plant physiology and plant pathology that investigate, using applied and genomic tools, a myriad of topics vital to the care and management of forests within the Central Hardwoods Forest Region.

The Genomics Lab is located in Pfendler Hall, Room 258, 715 W. State St., West Lafayette, IN, 47907.

Current Research

The major objectives of Dr. Lawson’s current research projects include:

  • Evaluating genetic diversity within black walnut and Persian walnut populations using bioinformatics techniques;
  • Investigating differential expression of genes observed in fine hardwood responses to abiotic stress conditions;
  • Genomics lab photo
  • Comparing individual samples of figured wood with those collected from non-figured Acacia koa using bioinformatics methodologies and using data obtained from the study to inform future research on fine hardwood species in the Central Hardwoods Region (CHR);
  • Determining soil suitability indices for black walnut and Northern Red oak of known genotypes.

Research Interests

Dr. Lawson's research interests are focused on comparative analysis of differentially expressed genes related to abiotic stress tolerance and wood formation in tropical hardwood and Central Hardwoods Region forest tree populations. Dr. Lawson's methodologies involve use of -omics, in silica, ex vitro, and molecular-based data acquisition aided by field experimentation.

Past Research

Previous research efforts in this field involved three distinct topics:

  • Overexpression of wax formation and salt tolerance genes in poplar to increase salt tolerance and improve water-use efficiency;
  • Manipulation of stomatal density in poplar to improve water-use efficiency;
  • Engineering drought tolerance in poplar.
