Senior Research Associate, School of Integrative Plant Science Plant Pathology and Plant-Microbe Biology Section
After completing my degrees at the Universities of Liverpool and Birmingham I left the UK in 1995 in search of good food and warm weather. Since then my work has taken me to Madrid (Spain), Santiago (Chile), Heidelberg (Germany) and Venice (Italy) on topics related to a range plant pathogens affecting a variety of cultivated crops both at fundamental and applied levels. My primary research interests focus mainly on virus discovery, molecular diagnostics, virus RNA structure and function, virus evolution and nanobiotechnology. I also have established experience in transgenics, biosafety, microscopy, virus movement, and bioinformatics. I’ve been here at Cornell since 2010.
RNA structure and function
Virus discovery and evolution
I have five current research activities, all related to studying viruses:
Diagnostics - improvements in the sensitivity, breadth and user-friendliness of molecular marker detection using established and novel techniques such as: LAMP, HTS, RPA, Arrays, qPCR, RCA, etc.
As detection methods become more sensitive, our ability to identify and monitor viruses in the environment becomes ever more refined allowing us to better implement pre-emptive measures to control the outbreak of a disease. In deciding which diagnostic technique to use there is often a trade-off between high-sensitivity and breadth on the one hand and cost and speed of detection on the other. Deciding which method to use and when is part of the challenge.
Virus Discovery - molecular and biological characterization of novel viruses.
Once a novel virus (or part of it) has been identified we can view its nucleic acids or proteins either as simple biomarkers for detection, or we can begin studying the biology of the virus in order to better understand how it is able to infect (and sometimes damage) its host. This can involve obtaining the nucleic acid information of one virus isolate or multiple isolates to get an impression of the genetic variation within the population or using a range of laboratory techniques to shed light on the mechanisms of virus infection.
Evolution - understanding the processes and mechanisms involved in virus adaptation both experimentally and computationally.
Once we have compiled a snapshot of the genetic variation within a virus population, we can use multiple computational tools to test broader global hypotheses using sequential data from public databases. This process is reiterative, allowing us to test and retest microevolutionary ideas in vivo. RNA viruses, in particular, are excellent models to explore the adaptability of genetic material.
RNA structure - determining the structure and role of viral genomic RNA in the infection process.
RNA is a multifunctional biological molecule. RNA viruses have to use it both to encode their genome and as a messenger RNA. Evolutionary constraints on genome size mean that these viruses use their RNA for multiple functions - a “code within a code”. Our interest centers on understanding the structural component of viral RNA and how it functions to interact and co-opt host factors into replicating its own genetic material.
Nanotechnology - exploiting the plasticity of virus encapsidation in the development of viral nanoparticles.
Viruses have evolved over millions of years to produce the “perfect” biological capsule. We exploit this property into developing nano virus-like particles (devoid of genetic material) for use in imaging and drug-delivery systems.
Outreach and Extension Focus
Before Cornell, I was regularly involved in outreach activities with the general public, special interest groups, growers and schools on the subject of biotechnology and biosafety (Veneto, Italy).
At Cornell, my interest in outreach is focused on exploring the link between farming communities across continents and how academia can be used as a hub to facilitate interactions and the exchange of ideas between these communities.
I also organize summer long research internships in molecular biology for Cornell Students at a number of prestigious international universities and research organizations though the EMBRE program.

I have a bit of a soft-spot for a "learning-by-doing" approach to teaching. My aim is to guide students to better understand how molecular biological theory and practice are connected and how they can be applied both in the long- and short-term to solve real-world problems.
