THE 'VIRAL' PROFESSOR
Arvind Varsani
New Zealand (8 years). I am currently based in the US in the Sonoran desert.
I strongly advocate UBUNTU – an African philosophy focusing on people’s allegiances and relationships, including those of the local community. I strongly believe that it is extremely important to engage the local community especially in research involving native fauna and flora which often has major cultural significance to indigenous peoples.
ASSISTANT RESEARCH SCIENTIST
Simona Kraberger
under the supervision of Arvind Varsani and then followed on to take a postdoctoral researcher position in the VandeWoude lab at Colorado State University in Colorado (CSU). At CSU, I work on a large interdisciplinary NSF funded project investigating feline retrovirus molecular ecology in large wild felids, namely mountain lions, bobcats and lynx. In 2017, I moved to Phoenix, Arizona, to join the Varsani lab at Arizona State University. As an Assistant Research Scientist, I work on a range of exciting projects, focusing on the ecology and evolution of single-stranded DNA viruses. My current primary projects include “unearthing the honey bee virome and effects of certain viral infections on honey bee behavior” and “Understanding the evolution and ecology of anelloviruses in large species of carnivore”. Being a nature nerd, I love the outdoors and exploring the Arizona desert which is my latest hobby.
POSTDOCTORAL RESEARCHER
Karla Vargas
My doctoral dissertation focused on the application of genomic approaches to the conservation of Sonoran wildlife. I am an NSF-Postdoctoral Fellow in the Varsani Lab working in collaboration with the Baja Geogenomics Consortium and the University of Arizona Conservation Genetics Lab. My current research focuses on host-virus dynamics and viral diversity associated with wild populations of vertebrate species across the Baja California peninsula and the Sonoran Desert in Arizona.

fact that we still know very little about them. I completed my PhD at the University of Canterbury in the Varsani Lab and my thesis was focused on the discovery of novel circular replication-associated protein encoding single-stranded DNA viruses in ecosystems using viral metagenomic approaches. I am interested in using next-generation sequencing technologies for the discovery of novel viruses in different environmental samples. Over the past couple of years I have been based in Berlin and were investigated the movement of infectious diseases in ground water, such as equine herpes virus. I have had the most amazing time being part of the Varsani lab in New Zealand and hope to have many more collaborations in the future.
FORMER PhD STUDENT
Daisy Stainton
at a US summer camp. I then returned to the University of Canterbury in 2009 to undertake a Masters’ degree which I subsequently upgraded to a PhD thesis. The research for my PhD focused on single stranded DNA viruses which infect banana plants. In particular, banana bunchy top virus (BBTV), a single-stranded DNA virus in the Nanoviridae family. I am interested in the global genetic diversity and the evolution of BBTV. My research also investigated the presence of three banana infecting badnaviruses, double-stranded DNA viruses in the Caulimoviridae family, in worldwide banana samples. Following this, I undertook a postoc at the University of Queensland. Australia and I am moving to the US shortly to take up a plant virology-based postdoc. In my spare time I enjoy volunteering for a youth group for young people with disabilities, reading and spending time with friends.
FORMER PhD STUDENT
Kata Farkas
focused on enteric viruses in groundwater, aiming to mimic their transport and behavior in saturated aquifers using protein- and DNA-labeled nanoparticles. After finishing my studies, I continued working in Arvind’s virus research group. I was involved in various project that uses viral metagenomics approaches to identify viruses (both known and novel) in various ecosystems. In 2015, I stared to work at the Bangor University, Wales, on the Viraqua Project (www.viraqua.uk). I have designed and validated methods for the recovery of enteric viruses in the aquatic environment in order to quantify infectious viruses, describe viral ecology and model viral transport in the environment. I can be found at the Environment Centre Wales (Bangor) or easily spotted at any health-related water microbiology conference, making very poor norovirus jokes.
FORMER GRADUATE STUDENT

I am currently undertaking my PhD at the University of Newcastle in Australia in plant biology.
FORMER PhD STUDENT
Adérito Monjane
My thesis project involved both fieldwork (sampling plant-infecting viruses) and laboratory work. The key research questions revolved around virus diversity, epidemiology, as well as studying how integral a process virus evolution is to a virus’ ability to infect valuable crops. Building on this experience, I am now working at the Norwegian Veterinary Institute, where I exploit the use of synthetic biology to sabotage key properties of a virus’ genome, so as to potentially make attenuated vaccines.
FORMER GERMAN GRADUATE STUDENT INTERN
Anja Jäschke
I primarily worked on plant-infecting geminiviruses. In 2012 I started a PhD at the University of Heidelberg analyzing the human immune response to a malaria vaccine candidate. Currently, I am working as a Postdoc at the University clinic Heidelberg where I am supervising the immunological analysis of a clinical phase I trial with the malaria vaccine candidate SumayaVac-1. I love travelling around the world.
FORMER UNDERGRADUATE STUDENT
James Hadfield
modern scientific research, running the gamut from molecular cloning work, sequencing, and phylogenomic analysis. It set me up for my PhD (University of Cambridge), where I worked on bacterial genomics, microbial resistance and interactive data visualisation. During my PhD I built phandango, a web-based visualization tool for interpreting the genomics of bacterial populations. I'm now in the Bedford lab at the Fred Hutch in Seattle, USA. There I work on nextstrain.org, which aims to provide real-time phylodynamics analysis and visualisation of pathogen evolution, especially where applicable to outbreaks and epidemics.
FORMER HONOURS STUDENT
Oliver Windram
human papillomavirus virus capsid proteins to generate structurally ordered epitopes for potential vaccine development. Also during this time, I was part of a larger team that sampled and mapped the distribution of various geminivirus in plant hosts throughout Africa. Part of this work helped reveal how viral recombination could be used to map the emergence of maize streak virus as a major agricultural pathogen in Africa. After leaving Arvind’s lab in Cape Town, I took on a PhD in Plant Systems Biology at the University of Warwick (England) and later a Post-Doc in yeast Synthetic Biology at Imperial College London (England). Now as a NERC Omics Fellow at Imperial College London, I am seeking to build and reconstruct large scale transcriptome defence networks in plants using my background in Systems Biology. I am combining this with my experience in Synthetic Biology to develop new ways of identifying key regulators in these networks via genetic rewiring of predicted regulators. Additionally, driven by my observations of the broad diversity of crop stress phenotypes throughout Africa, and the rest of the world, my group is also seeking to define more quantitative ways of defining plant stress phenotypes using deep learning image analysis. The ultimate aim of this is to relate quantitative plant metrics to underlying transcriptomic and metabolomic responses to help generate more realistic in-field defe
