Dr Francisco M. Ochoa Corona is an associate professor at the National Institute for Microbial Forensics & Food and Agricultural Biosecurity (NIMFFAB), and Department of Entomology & Plant Pathology, Oklahoma State University since August 2008. Dr. Ochoa Corona is a forensic plant pathologist, specializes in developing and delivering reference diagnostics for exotic, naturalized, and indigenous plant viruses and other phytopathogens of relevance to agricultural biosecurity and microbial forensics. His work is applicable to plant pathogens, and more recently to waterborne plant viruses, insects that can be intercepted at borders, or detected by general surveillance of field settings or within transitional facilities. Ochoa Corona's research in plant pathology contributes scientific input to regulatory officials regarding plant health emergencies and focuses on targeted aspects of forensic plant pathology that are relevant to agricultural biosecurity in Oklahoma, the southern plains, the United States and other regions of the world such as the South Pacific and Central and South America. Dr Ochoa Corona joined OSU from the Investigation and Diagnostic Centre (IDC) at Biosecurity New Zealand (BNZ), Ministry of Agriculture and Forestry (MAF), where he was Principal Adviser Virology.

'Global Issues in Agricultural Biosecurity and Forensics'
Would you like to know about Biosecurity, biosafety, bioterrorism, biowarfare, biocrimes, microbial forensics, emerging organisms, invasive species, food safety, food biosecurity, quarantine, responses, surveillance, detection, diagnostics, and how all are related with elements of a biosecurity system and how biosecurity and microbial forensics integrate to science, to Ag specialties, animal and human health, economics, justice and defense? This is a new attractive, and interesting professional option that complement any major and/or prepare for a career in biosecurity and microbial forensics, related research, science or roles in biosecurity agencies. This course meet the needs of a new group of students seeking for a component of biosecurity and/or microbial forensics in their major and/or carrer. ENTO/PLP 2143 introduces to the topics of biosecurity, forensics, research, consultancy, and offers a global biosecurity vision interconnecting roles of different careers with biosecurity. Students learn from class work, readings, reporting, study cases of global significance including pathogenic microorganisms, insects and weeds, guest experts, and a final comprehensive simulation exercise. This new course enhances the Ag and Forensics science programs and offers a new educational perspective not covered by current Ag and Forensics science currilulums.
The way I visualize and teach Biosecurity in ENTO/PLP 2143 . (Ochoa-Corona, F.M. 2011. Australasian Plant Pathol. 40:335-338). Interacting elements of a biosecurity system showing natural and globalized anthropogenic pathways through which exotics are introduced into a biological system, region or country. This diagram also shows scientific output moving toward policy and biosafety systems from scientific disciplines to encompass science policy and other instruments and activities that allow biosecurity to react, remediate and manage risks through deliverables to different sectors of the society.
I follow the Coach:Athlete model which is more appealing to me than the Teacher:Student model. There is nothing wrong with the Teacher:Student model, but I believe the Coach:Athlete fit better my purposes and goals. The Teacher:Student is a nice classic. The teacher teach and the student listen and study, teacher and students play their roles interacting around a given subject. The communication tends to be in a single direction, although not always. The 'status quo' includes students have to make merits to pass. Although matter of controversy, some think the harder the course the better, and opinions are frequently divided about the learning outcome. The Coach:Athlete model has an innovative perspective, both coach and athletes interact around the subject with a common goal, winning! The victory (getting a 'A') is equally shared. The communication is commonly bidirectional. The hard work become a standard (like an Olympic qualifying threshold to beat), and the coach will do the best in his capacity to mentor and 'inspire' the team (the whole class) to win (knowledge = 'A'). At the end the athlete get the medal and the coach its recognition. Got the message? Don't think it twice come on board to win and learn!
"Great class! Fantastic for anyone interested in learning more about biosecurity, diagnostic technology, and government quarantine policies. Topics include: Bioterrorism, International Trade, Insect Vectors and Plant Diseases, Quarantine and Surveillance, Diagnostics, and so much more! Learn more from a professor that has worked in this area!"Kelsy Thompson
"Global Issues in Agricultural Biosecurity and Forensics" really opened my eyes to a whole new world of cutting edge research and relevance to government policies. This class covers everything you will need to know from global government Biosecurity to the diagnostic labs that first discovers the problem. Dr. Corona does a wonderful job at tracing the processes and mechanics of each step of the response, while making it fun and relevant to the students.Samantha Sanders

The research in our laboratory focuses on inventing, innovating and/or improving tools for collection of microbial specimens applicable in biosecurity and microbial forensics. We also center our attention upon the development and/or improvement of detection-discrimination and/or diagnostics procedures for microbes and insects. Our research also targets the identification of molecular landmarks and signatures of value for detection, and the implication of this genetic data on taxonomical relationships, such as host-pathogen associations. Our research is applied to regional pests, regulated organisms, select agents or high consequence microorganisms. Mi research program is also interested in decision support tools for prioritization, emergency management, and prediction of biosecurity threats. We are also interested in monitoring dynamics of relevant plant pathogens, tracking their pathways, global dispersal routes, and delimiting the bio-geographic distribution.
The way I understand and teach research defines "Invention as the first ocurrence of an idea for a new product or process, while innovation is the first attempt to carry it out into practice" (Jan Fagerberg, Innovation: A Guide to the Literature": "The Many Guises of Innovation: What we have learnt and where we are heading", Ottawa, October 23-24.2003). Therefore innovation is not inventing, both are dynamic, time lapsed, and complementing processes. Invention is the idea and innovation is the realization of an invention. In practice my research program invent to solve own or given problems and innovate own or given ideas. The assumption of this concepts makes my team an effective and flexible science provider. Similarly, I believe extraordinary ideas are out of the ordinary and so what may apparently look as a conventional, extravagant or a silly idea is never put away inmediatly but given equal considerarion and analysis. As a consequence we prioritize ideas, some are innovated and some other archived, 'further munched' then innovated at the right time.
