Travel Grants & Workshops

Travel Grants | Electrical Penegration Graph Workshop (EPG) | Omics Workshop

Travel Grants

Travel grants are available to help defray travel costs to the symposium for participants giving oral or poster presentations. While travel grants will primarily support graduate students, postdoctoral fellows and early career investigators, other more senior investigators in need of support will also be considered. The HPIS Symposium travel grants are supported by grants from the USDA and BARD; all US and international participants are eligible to apply.

The travel grant application is available at this link. Please send completed applications to No application will be accepted by mail.

Travel Grant Deadline: April 1, 2014

Electrical Penetration Graph (EPG) Workshop

Neil A. Campbell Science Learning Laboratory
University of California, Riverside
June 19-21, 2014 (Pre-HPIS Symposium Event)
Instructor: Freddy Tjallingii, EPG Systems, Wageningen, Netherlands

The program of this three-day Electrical Penetration Graph (EPG) course covers theoretical aspects of EPG and hands-on training. The objective of the workshop is to train or refresh practical skills of new and old EPG users. The EPG technique is used in many studies on aphids and other insect herbivores with piercing-sucking mouthparts. It allows users to monitor details of stylet penetration behavior in real time. It is has shown to be a powerful tool for studying plant-insect interactions that are important in host selection, plant defense and resistance, and transmission of plant pathogens by piercing-sucking vectors.

Morning sessions will have lectures on the background, principles and applications of EPG, and interpretation of EPG data. During afternoon sessions, participants will engage in practical training with EPG recording, waveform analysis, and data processing. The afternoon practical training can accommodate a maximum of 16 participants, but the morning lecture sessions on EPG theory can be attended by more.

All participants are required to present a 10-minute, informal summary of their present/intended future research activities. If possible,  EPG results/aims/expectations should be highlighted. If you want more time, contact us in advance; if the schedule permits more time will be allocated.

Omics Workshop

Omics approaches enable biologists to extend the reach of molecular biology to study interactions among specific genes, proteins, and metabolites that orchestrate interactions among plant pathogens, pathogens and insect vectors. The OMICS workshop will be focused on the latest advances in proteomics, metabolomics, transcriptomics, and computational biology developments as applied to the vector biology field. Speakers include Jim Bruce (University of Washington), Carolyn Slupsky (UC Davis), Cecilia Tamborindeguy (TAMU) and Zhangjun Fei (Boyce Thompson Institute). The Bruce lab pioneered Protein Interaction Reporter Technology, which enables measurements of in vivo protein interactions on a proteome-wide scale using mass spectrometry. The Slupsky lab uses NMR-based metabolomics to probe the impacts that vector-borne plant pathogens have on plant hosts. The Tamborindeguy lab measures host-vector-pathogen interactions using multiple ‘omics approaches. The Fei lab is focused on developing computational tools and resources to analyze and integrate large scale ‘omics datasets with a focus on plant viruses. A panel discussion will follow the workshop to allow participants to interact with speakers and discuss ongoing projects and the future of ‘omics technologies in the Vector Biology field.
