Dr. Marc Fuchs
Fuchs received his Master’s and PhD degrees from Université Louis Pasteur in France. He has worked on viruses of fruit crops and vegetables over the past 30 years, developing detection techniques, understanding spread, and investigating management strategies.
Osterbaan is a 6th year PhD candidate conducting her thesis research on molecular-host interactions of Grapevine fanleaf virus (GFLV). GFLV is one of the most devastating viral diseases of grapevine and causes a number of symptoms on grapevine, including mosaics, abnormal leaf morphology (fan-leaf), shortened internodes and premature vine death. Though GFLV has a long history in virological research, little is understood of the molecular interactions responsible for these symptoms. Osterbaan’s research is focused on discovering the molecular mechanisms underlying GFLV symptom development in the plant model species Nicotiana benthamiana, with the aim of translating insights gained in this system to solutions for symptom management in grapevine.
Cieniewicz is in her fifth year as a PhD student in the Fuchs lab. Her research is focused on the epidemiology and ecology of grapevine red blotch disease. Grapevine red blotch virus is a recently recognized virus of Vitis spp. that is threatening vineyard profitability by impacting fruit quality. Vector-mediated spread, while not yet apparent in the eastern United States, is occurring in vineyards on the west coast. Her goal is to improve our understanding of the factors mediating spread of this disease and ultimately inform management strategies in vineyards.
Maddie is in her 1st year as a PhD student. She was a Cornell Summer Scholar in the Fuchs lab in 2016 and graduated from Otterbein University in Ohio in 2018 with a B.S. in Biology. She is working on diversity and ecology of grabloviruses in grapevine, specifically grapevine red blotch virus (GRBV) and wild vitis virus 1 (WVV1). Maddie is interested in further understanding the epidemiology and transmission of GRBV. While WVV1 has only been found in wild grapes, her goals also include studying the potential impacts of the virus in vineyards should commercial grapes become infected. This knowledge would help develop proactive management strategies for at risk vineyards.
Jiyeong (Jess) Choi
Jess is in her 1st year as a PhD student. She was a Cornell Summer Scholar in the Fuchs lab in 2017 and graduated from Auburn University in Alabama in 2017 with a B.S. degree in Microbiology. She is interested in exploring the molecular mechanisms of GFLV suppression of RNA silencing. Jess believes that clarifying this counter-defense mechanism would enhance our understanding of GFLV pathogenicity factors and the critical role of silencing suppression in virus-host interactions.
Alex is in his 1st year as a PhD student. He was a Cornell Summer Scholar in the Fuchs lab in 2017 and graduated from the University of Missouri in 2018. Alex is working on grapevine red blotch virus transmission by the three cornered alfalfa hopper.
Research Support Specialist
Rosemary Cox has been a Research Support Specialist in the Fuchs lab since 2007. Her responsibilities have focused mostly on the processing and testing fruit and vegetable crop samples for various viruses using serological and molecular diagnostic assays. Rosemary is also involved in research projects on grapevine viruses.
Yen Mei Cheung
Mei has been a Technician in the Fuchs lab since 2004. Her primary responsibilities relate to the production and maintenance of healthy and virus-infected plants in the greenhouse and field. Mei also provides assistance in the laboratory for media preparation and sample processing.
Fu-Wah has been a Technician in the Fuchs lab since 2014. He is assisting the processing and testing of fruit crop samples for viruses. Fu-Wah is also involved in research projects on grapevine viruses.
