Lab Team

Nelly Camargo, BSc

Research associate II

Nelly Camargo 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.

Charlie Jennison, PhD


Charlie JennisonDr. Charlie Jennison received his master’s degree in medical parasitology from the London School of Hygiene and Tropical Medicine, researching novel diagnostic tests for schistosomiasis in Uganda. After three years researching sexually transmitted infections in Cambridge, UK, he undertook a PhD at the Walter and Eliza Hall Institute of Medical Research in Melbourne, where he focused on the gametocyte and sporozoite biology of P. falciparum. In the Kappe and Vaughan Labs, he is continuing his research interests in exoerythrocytic parasite biology, investigating proteins important for parasite infection of mosquito and human/rodent hosts, as well as working to advance the design of genetically attenuated parasites as a malaria vaccine. Outside of the lab he enjoys hiking, snowboarding and local IPAs.

Spencer Kennedy

Research technician I

Spencer KennedySpencer Kennedy is a research technician in the Kappe and Vaughan Labs working on the human malaria parasite Plasmodium falciparum. Having graduated from the University of California, Davis with a BS in biochemistry and molecular biology in 2016, he was involved in internships with the Wu Lab studying phosphorylated peptides in lung cancer, and with the Peng Lab doing computational biology on breast cancer. Since joining the center in 2017, he has been focused on the ongoing phase 1 clinical trial for a genetically-attenuated parasite (GAP) vaccine. He is also the primary technician for the Clinical ACL-I Insectary. Outside of work, Spencer is an avid tennis player and spends time volunteering with local non-profits that help homeless children in King County.

Sudhir Kumar, PhD


Sudhir KumarDr. Sudhir Kumar is a postdoctoral scientist in the Kappe and Vaughan Labs. He obtained his PhD from the National Institute of Immunology/Jawaharlal Nehru University, New Delhi, India, working on calcium and cyclic nucleotide mediated signaling in Plasmodium falciparum erythrocytic stages. His current project focuses on experimental genetic crosses between different artemisinin-resistant and -sensitive parasites to discover the mechanism of drug resistance in Plasmodium falciparum.Outside of the lab he likes to travel, read, play badminton and watch cricket.

Shawna Stonum

Senior administrative assistant

Shawna Stonum began supporting labs at 307 Westlake in December 2017 and joined the Kappe and Vaughan Labs in October 2018. Shawna has supported staff in both the non-profit and for-profit sectors in a variety of industries, including social services, health care, finance and now life sciences. Her favorite groups of people are those who use their skills to benefit the greater good. Shawna derives great satisfaction in being an integral part of the puzzle that works to potentially save lives and improve the quality of living those lives. Free time hobbies include acrylic painting and spoiling two grandsons.
