Lab Team

Daniela Andrade, PhD


Daniela AndradeDaniela Andrade graduated with a PhD in Infectious Diseases and Immunology at the University of California at Berkeley, where she studied the antibody response to natural dengue infection. Her interest in infectious diseases dates back from her work in Brazil, where she joined efforts to immunoprofile patients with acute Chagas disease living in an endemic area. In the Sather lab, she focuses on investigating the B cell and antibody response elicited by HIV immunization using cutting-edge techniques, such as single cell sequencing. Outside the lab, Daniela enjoys hiking trails along the Pacific Coast, ice-cream tasting, photography and stand-up comedy.

Nicholas Dambrauskas, BS

Research Associate III

Nicholas DambrauskasNicholas Dambrauskas received his BS in biology from the University of Vermont in 2004 and then took a position at the University of Utah, where he studied receptor ligand interactions and their role in cell motility during CNS development. He joined the Sather Lab in 2014 and is focused on immunogen design, production and characterization. He spends his time outside of the lab practicing Aikido and climbing.

Catherine Darcey

Research Associate II

Rossana de la Noval, MA

Grants and Contracts Administrator

Rossana de la Noval received her MA in anthropology from the University of Illinois at Urbana-Champaign, and worked as an archaeologist before shifting to administrative and project coordination roles in the design and science fields in the past 10 years. Outside of the office she enjoys volunteering, yoga and hiking, and is an avid soccer fan.

Olesya Trakhimets, BS

Research Associate II

Olesya TrakhimetsOlesya Trakhimets received her BS in biology and anthropology from the University of Utah in 2013, where she worked in the Trede Lab conducting pre-clinical drug studies against acute lymphoblastic T-cell leukemia and in the Dearing Lab studying the Cyp2B detoxification enzyme in desert woodrats. In 2014 she joined the U.S. Peace Corps and spent two years working in Ghana as a community development worker, with a focus on malaria and HIV prevention, education and clean water access improvement. Inspired by her Peace Corps experience, she joined the Sather Lab in 2017 with the hopes of pursuing a career in infectious disease research. Outside of the lab, she enjoys playing Ultimate Frisbee, rock climbing, hiking, reading and eating cheese as often as possible.

Vladimir Vigdorovich, PhD

Research Scientist III 

Vladimir VigdorovichDr. Vladimir Vigdorovich’s interests span the subjects of protein structure, recognition and host-pathogen interactions. He received his BS at the University of Minnesota, where he studied the molecular genetics of the parasite Cryptosporidium parvum. His interest in virology then brought him to Seattle and Fred Hutch for graduate studies focusing on molecular mechanisms of retroviral entry. After receiving his PhD, he went on to the Albert Einstein College of Medicine, where his work focused on protein interactions and structural biology of the immunological synapse. In the Sather Lab, Vigdorovich is working on developing new immunogens from proteins made by malarial parasites, as well as developing the computational tools for analysis of the immune response.

Ganesh Ram Visweswaran, PhD

Research Scientist III

Ganesh Ram ViswesvaranDr. Ganesh Ram Visweswaran graduated from the University of Groningen in the Netherlands, where he studied the functionalities and biochemical properties of bacterial cell wall hydrolases and their -binding domains. His research interests include infection biology and vaccine development.  As a postdoctoral fellow (University of Oslo, Norway), he worked on DNA–vaccine development projects for Malaria. He also possesses about two years of industrial experience (Novozymes and Biocon), working on enzyme engineering and process development projects. He joined the Sather Lab in March 2019. His work is focused on the development of malaria vaccines targeting the pre-erythrocytic phase of Plasmodium vivax to address relapse infections. Apart from work, he enjoys playing badminton and tennis, and likes to travel.

Alex Watson, BS

Research Technician III

Alexander Watson received his BS in Chemistry from Seattle University in 2014. There he studied organometallic synthesis on novel triple decker molecules with an emphasis on their applications as molecular wires. After graduating he made the jump to biology at the Fred Hutchinson working on rare pediatric brain tumors, focusing on biophysical characterization and molecular biology. He joined the Sather lab in 2018 and focuses on protein design and production, creating immunogens for malaria. Outside of the lab he spends his time training in taekwondo, most things outdoors, and building and modifying computers.

Ashton Yang, BS

Research Associate I

Ashton Yang received her BS in Cellular and Molecular Biology from Seattle Pacific University in 2018. During this time, she worked in the J. Lampe Lab at Fred Hutchinson Cancer Research Center helping to investigate how diet affects cancer risk, and in the Urdahl lab at the Center for Infectious Disease Research focusing on how interferons affect tuberculosis infection in macrophages. After graduating, she spent a year in the Totten lab at Harborview working to elucidate the attachment domain of Mycoplasma genitalium to host cell targets. She joined the Sather lab in 2019 and focuses on cell-based assays and next generation sequencing for HIV vaccine development. Outside of the lab, she enjoys eating breakfast foods, going for runs in Seattle parks, and knitflixing (knitting and Netflix).
