    Dr. Matthew (Matt) Gray is a professor in the Department of Forestry, Wildlife and Fisheries at the University of Tennessee (UT) and the Associate Director of the UT Center for Wildlife Health.

    .  Dr. Gray’s research focuses on natural and anthropogenic mechanisms that are responsible for ranavirus emergence.  Much of his research has focused on understanding transmission dynamics, identifying traits of highly susceptible host species, and modeling the effects of ranavirus on population persistence.  He is a founding member of the Global Ranavirus Consortium, and helped organize the first two international symposia on ranaviruses.  Dr. Gray is originally from Michigan, USA, and holds degrees from Michigan State University (B.S.), Mississippi State University (M.S.), and Texas Tech University (Ph.D.).

  • Jesse L. Brunner

    Dr. Jesse L. Brunner

    Assistant Director

    Dr. Jesse L. Brunner is an assistant professor of biology at Washington State University focusing on the ecology of infectious diseases. His dissertation work at Arizona State University centered on the transmission and persistence of the Ambystoma tigrinum virus. After a post-doc studying the community ecology of Lyme and other tick-borne diseases, a continued research interest, Jesse returned to studying ranaviruses. His current work focuses on the form and dynamics of pathogen transmission, susceptibility of individuals and populations, and the factors that influence disease emergence.

  • Amanda Duffus

    Amanda L. J. Duffus Ph.D.

    Secretary & Treasurer

    Dr. Amanda L. J. Duffus completed her BScH with Distinction in Biology in 2004 at Queen’s University, Kingston, Ontario, Canada. In 2004 she began working on amphibian ranaviruses at Trent University in Dr. Michael Berrill’s lab where she completed her MSc in 2006. In 2010, she completed her Ph.D. at the Institute of Zoology, Zoological Society of London and Queen Mary and Westfield College, University of London, London, United Kingdom. During her PhD work, she examined multiple aspects of the biology of the ranavirus(es) that occur in populations of amphibians in the United Kingdom. While Dr. Duffus has worked on amphibian ranaviruses since 2004, her current position is teaching focused. She is currently an Assistant Professor of Biology at Gordon State College where she instructs a variety of lower and upper division undergraduate courses. She remains engaged in ranavirus research and the scientific community through her activities with the GRC, the Southeastern Partners in Amphibian and Reptile Conservation (SEPARC), on the editorial boards of two journals, and collaborations with colleagues.

  • Greg Chinchar

    Dr. V. Gregory Chinchar

    Honorary Advisor

    Dr. V. Gregory (Greg) Chinchar is a Professor in the Department of Microbiology and Associate Dean, School of Graduate Studies, at the University of Mississippi Medical Center.  He will retire as a full-time faculty member on June 30, 2014, but intends to return to UMMC half time beginning on October 1, 2014.  As Professor/Associate Dean  Emeritus he will continue to teach virology to  medical, dental, and graduate students, and perform administrative duties within the School of Graduate Studies.  Although he will not be directing graduate student research, he hopes to remain an active participant in various ranavirus studies.  His interests are primarily molecular and are focused on understanding the role of various ranavirus genes in replication, with specific interest on those genes that control virulence, host range, and immune evasion.

  • Ellen Ariel

    Dr. Ellen Ariel

    Australian Representative

    Dr. Ellen Ariel is a senior lecturer in Virology at the School of Veterinary and Biomedical Sciences, James Cook University and supervises students working on in viruses of fish and reptiles. Previously she was the coordinator for the European Community Reference Laboratory for Fish Diseases for 11 yrs. The general functions and duties were to standardize and harmonize diagnostic techniques in the 25 Member States and app 10 associated states, in order to increase proficiency in disease surveillance in fish and subsequently reduce the spread of diseases between member states via the live fish trade. Ellen was one of a 3 person steering group for the PANDA project (Permanent Advisory Network for Diseases in Aquaculture),which cooperated with over 400 scientists in the network to seek policy advise for the European Commission, and also coordinated the RANA (Risk assessment of new and emerging systemic iridoviral diseases for European fish and aquatic ecosystems) research project. She received her PhD from JCU in 1997 on the topic: “Aspects of ranavirus infection of water-associated reptiles in North Queensland.”

  • Rolando Mazzoni

    Dr. Rolando Mazzoni

    South American Representative

    Dr. Rolando Mazzoni is from Uruguay where he received his DVM degree and worked as a post-doctoral researcher at the Federal University of Goiás, Brazil.  He studies diseases in farmed frogs.  Dr. Mazzoni and his group were the first scientist to document ranavirus in Brazil and Uruguay in farmed American bullfrogs.

  • Yumi Une

    Dr. Yumi Une

    Asian Representative

    Dr. Yumi Une is a veterinary pathologist and professor in the School of Veterinary Medicine at Azabu University, Japan.  She studies infectious diseases in exotic and wild animals.  Dr. Une was the first scientist to document ranavirus in Japan in exotic American bullfrogs, and since then has learned that the pathogen causes clinical disease in several rare native amphibian species, including salamanders in the family Hynobiidae.  The photograph is an endemic frog (Bufo gargarizans miyakonis) of Miyakojima.

  • Thomas B. Waltzek

    North American Representative

    Dr. Tom Walzek is an Assistant Professor in the Department of Infectious Diseases and Pathology at the University of Florida and  Co-Director, Aquatic Animal Health Program.

  • Rachel Marschang

    European Representative

    Dr. Rachel Marschang (PD. Dr. med. vet., DECZM [herpetology], FTÄ Mikrobiologie, ZB Reptilien) is a veterinary microbiologist working on the diagnosis of infectious diseases in reptiles and other exotic animals at Laboklin, a private diagnostic laboratory in Bad Kissingen, Germany and an adjunct professor at the University of Hohenheim in Stuttgart, Germany. She is a diplomate of the European College of Zoological Medicine (herpetology) and a certified specialist for microbiology (FTÄ Mikrobiologie) and for reptile medicine (ZB Reptilien). She is the president of the Association of Reptilian and Amphibian Veterinarians (2013-2014). Her research focuses on diagnosis of viral infections in reptiles and she has been involved in the detection and characterization of ranaviruses in many different reptile species in Europe.
