Biley Abatiyow is an undergrad student at the University of Washington studying Medical Anthropology and Global Health. She joined the lab June 2019 as an intern. Her interest in malaria stems from her global health classes were she learned about the effects malaria has on children under the age of five in many countries around the world. Studying the consequences of the infectious disease sparked her interest in malaria vaccine research. Some of her skill sets include conducting genomic DNA preparation through PCR analysis, and many other molecular-bio work. Outside of the lab she likes to travel, hiking and spending time with family.
Research Associate II
Janna Armstrong is a research associate II with a bachelor’s degree in zoology from the University of Hawaii at Manoa, where she spent her senior year focusing on human parasitology and infectious diseases. She spent the last 20 years focusing her work in molecular biology with The Dow Chemical Company’s animal health and gene discovery program in their agricultural biotech division. After leading a successful, multifunctional project team for 10 years in gene discovery, she decided to leave Dow to pursue her true passion in human parasitology related research – mainly malaria vacinology. When she is not doing science, she enjoys woodworking, remodeling homes, and doing outdoor activities with friends and family.
Silvia Arredondo, PhD
Research Scientist III
Dr. Silvia Arredondo is a staff scientist with a PhD from the University of Texas at Austin, where she was formally trained as a chemical engineer with emphasis on protein engineering and disulfide bond formation. Her interest in applying her skills to the fight against malaria led her to a postdoctoral fellowship at the National Institutes of Health. During her time at the NIH, she focused on the structural and functional characterization of P. falciparum blood stage 6-cys proteins. Her work yielded the first molecular structure for this protein family. Arredondo remains intrigued by the 6-cys proteins and she is interested in elucidating the roles of the members of this family in the pre-erythrocytic stages.
Will Betz, MS
Research technician II
Will Betz is a research technician with a MS degree from the University of Southampton. He has worked at the center since 2008. Previously, he worked as a field biologist/wildlife conservationist in New Guinea. It was there that he witnessed the pervasive and debilitating impact that malaria has on human health and economic development, and he himself contracted Vivax malaria on two occasions. His primary work responsibility is maintaining stocks of rodent malaria–infected mosquitoes, as well as supplying researchers with rodent and human malaria parasites via mosquito dissection. Outside of work, Betz enjoys photography, hiking and travelling with his wife, Debbie.
Nelly Camargo, BSc
Research associate II
Nelly Camargo joined Dr. Stefan Kappe’s Lab, then at New York University, in 2002. She received her BSc from the Universidad Nacional de Colombia. Nelly has played an integral part to many research programs in the lab spanning from establishing transfection technology of the rodent and human malaria parasites to supporting the Human Challenge Center (HCC) with malaria clinical trials. In partnership with the HCC, Nelly has been involved in both safety and efficacy trials in human volunteers with a genetically attenuated parasite that was created in the lab. She believes that excellent, honest, persistent and truly cooperative work will eventually lead to control of the damage inflicted to so many people by the Plasmodium parasite that causes malaria. Outside of the lab Nelly enjoys spending time with her family.
Debashree Goswami, PhD
Dr. Debashree Goswami received her PhD from the Max Planck Institute for Molecular Biomedicine and University of Münster, Germany, in 2016. During her PhD, she investigated the role of a receptor-ligand pair involved in the process of leukocyte transendothelial migration using gene-deficient mice. For her postdoc, she wanted to transition into a lab involved in applied research, which brought her to the Kappe Lab. In the Kappe Lab, she is currently working on the malaria vaccine project that requires generating genetically attenuated parasites (GAP) that arrest late in the liver stage. These late-arresting GAPs would serve as the next potential vaccine candidate. In her spare time, she enjoys playing tennis and volleyball and going on hikes.

Here she will be involved in the HIPC2 project in which she will aim to characterize the immune responses that are elicited in several malaria-vaccine trials, and hopefully identify correlates of protection. In addition, she will utilize in vitro and ex vivo assays in order to get a more mechanistic understanding of antimalarial immunity. Outside the lab, she enjoys discovering Seattle, especially the culinary highlights the city has to offer.

Ashley Vaughan, PhD
Research assistant professor
Ashley Vaughan, PhD, is a research assistant professor. He received his PhD from the London School of Hygiene and Tropical Medicine. During his tenure in the Kappe Lab, he showed the importance of the parasite’s fatty acid synthetic pathway for sporozoite and liver stage maturation. He also researches how to elicit the most protective immune response after vaccination with genetically attenuated parasites. Ashley’s collaborations with Sebastian Mikolajczak led to significant advances in the use of human-liver chimeric mouse models in studying malaria. This includes complete liver stage development and the transition to blood stage malaria in the mouse for the human malarias Plasmodium falciparum and Plasmodium vivax. He has also used this mouse model for the creation of experimental Plasmodium falciparum genetic crosses, a significant advance that should aid in our understanding of Plasmodium falciparum drug resistance. Ashley continues to be fascinated by basic parasite pre-erythrocytic biology and uses rodent malaria and parasite transgenesis to understand how the parasite interacts with its vector and host during sporozoite and liver stage development. Outside of the lab, he is a keen hiker, traveler, gardener and scuba diver, pastimes he enjoys with and without his husband, Rafael.
