Research Interests

The University of Chicago
  1. Investigating the fitness effects of newly evolved genes in Drosophila melanogaster and identifying new genes that are essential for reproduction
  2. Exploring the functional relationship between new genes and their progenitor genes in Drosophila melanogaster
  3.  Contributed to a novel theory on the evolution of gene structure
University of Illinois
  1. Investigated the early evolutionary processes of Carica papaya's unique sex chromosome system by physically mapping, sequencing, and annotating the sex-specific regions of the hermaphrodite sex chromosomes
  2. Explored sex chromosome evolution in the family Caricaceae, by sequencing and annotating monoecious Vasconcellea monoica BACs corresponding to the sex-specific regions of the papaya sex chromosomes and by analyzing flow cytometry data for a selection of Caricaceae species to draw conclusions about the presence of sex chromosomes
  3. Contributed to the papaya and lotus genome projects by exploring gene pathways of interest and producing genetic maps
Augustana College
  1. Discovered the genetic diversity of a population of endangered Delphinium bakeri, using genetic mapping
