Lisa Fraser

I am using RNAi to disrupt the development in the filarial parasite Brugia malayi which is a causative agent of lymphatic filariasis. I suppress members of the cathepsin cysteine protease super family in order to understand the process of molting which is an essential component of the parasite's lifecycle.

Paul Airs

Emigrating to Iowa from England to pursue a graduate degree in Molecular Entomology was a daunting concept at first. I am currently one year into my master’s program here, studying the Sub-Saharan malaria mosquito Anopheles gambiae. The research, funded by the Foundation for the National Institutes of Health, is aimed at developing molecular mosquitocides by means of species targeted RNAi based gene knockdown.

My research interests focus on understanding innate immunity in Pacific White Shrimp (Litopenaues vannamei ) and utilizing RNA interference ( RNAi) technology to protect against shrimp viral diseases including Infectious Myonecrosis Virus (IMNV) and White spot Syndrome Virus (WSSV).



Tyansning (Tyas) Kroemer

My research project is to synthesize dsRNA that target White Spot Syndrome Virus (WSSV) genes as antiviral molecules and investigate the dsRNA protection from WSSV infection in the shrimp Litopenaeus vannamei. In addition, the effects of environmental stressors on Infectious Myonecrosis Virus (IMNV) infection in the shrimp will also be investigated.



B. M. Dunphy

I take part in and oversee mosquito rearing for the lab and the Iowa Mosquito and Arbovirus Surveillance Project.  I also contribute to a number of different research projects, including the current effort to develop molecular mosquitoes against the vector of human malaria parasites.



Undergraduate students are the key to every project ongoing in the lab.  Students join the lab as hourlies, interns, or students earning credits for independent research projects.  Many students have supported our summer research program in surveillance for mosquitoes, ticks, and mosquito- and tick-borne pathogens.  They are also instrumental in mosquito husbandry efforts.   More details on previous lab members can be found in our Laboratory Alumni page.
