Research Interests

1. Determine how insect blood cells recognize foreign materials and transmit this information to the insect of the blood cell
   2. Look at the means that selected types of nematodes interact with insect resistance to select for pathogens that can overcome the resistance killing the insect. This will be sued in controlling lawn damage induced by the insects.

Current Research

GTPases and hemocyte adhesion to foreign bacterial surfaces
