High throughput phenotyping methods and robust genotyping using next generation sequencing technique are currently being used in our lab. We are also conducting genomic selection, cataloging the genomic variants for disease resistant and sugar metabolism gene for sugarcane breeding. Developing improved cultivar for commercial sugarcane (Saccharum spp. Hybrid) for sustainable and higher sugar production. jeanluc.jannink@usda.gov; 607-255-5266 Researcher’s statement: My research focuses on statistical approaches to analyze and interpret the increasing quantity of DNA data available to breeding programs in combination with the phenotypic diversity these programs traditionally excel at putting to use. High throughput methods for collecting phenotypes are also developing so that we also need new approaches to leverage this high-dimensional data to accelerate gain from selection. Given this increased emphasis on data, we also work on information technology that makes it easier for breeders to handle more, and more diverse, data. In some way, all the analyses we work on aim to enable programs to make better selection decisions more rapidly. rebecca.schmidt@usda.gov; 509-454-6556 Researcher’s statement: The biological control of arthropod pests of tree fruit by predators and parasitoids. We study conservation of resident natural enemies through development of selective pesticide programs, landscape manipulation, and supplementary food products. We are also developing best practice guidelines for purchasing and releasing commercially available natural enemies for pest control, including timing and release rates and testing efficacy of drone releases. My team also studies the basic biology of natural enemies, including predatory mites, earwigs, spiders, predatory bugs, ladybeetles, and parasitoid wasps (Trechnites insidiosus, Ganaspis brasiliensis, and Leptopilina japonica). peishih.liang@usda.gov; 808-959-4349 Researcher's Statement: I am a Research Agricultural Engineer, and my research focuses on applying spectroscopy, imaging, sensors, and x-rays in postharvest food quality and safety, and pest management.

Our lab is dedicated to generating molecular resources for these species that can be used in breeding programs for crop improvement, with emphasis on resistance to biotic and abiotic stressors. Our approaches include whole genome sequencing, genetic mapping, pathogen characterization, QTL analyses, transcriptomics, hyperspectral imaging, etc. We are also pursuing gene silencing and gene editing techniques as well as characterization of the ‘berryland’ soil microbiome. Our multidisciplinary program involves lab, greenhouse and field work as well as close collaborations with the local grower community. I am based in Chatsworth, NJ, and headquartered out of the Genetic Improvement of fruits and Vegetables Lab (GIFVL) in Beltsville, Maryland (NEA). jose.ramirez2@usda.gov; 309-681-6195 Researcher’s statement: Dr. Ramirez’s research include the study of multipartite interactions (insect-pathogen-symbiotic microbe interactions) to identify factors that influence pathogen infection in the arthropod host. Current efforts also involve the isolation and characterization of entomopathogenic microbes to develop novel microbe-based biopesticides to control arthropod vectors and the pathogens they transmit. brian.rector@usda.gov; 775-784-6057 Researcher’s statement: My research is focused on classical biological control of invasive weeds; natural enemies (e.g. insects, mites, fungi) from the native range of an invasive weed species are evaluated in the laboratory/greenhouse and petitioned for release into the invaded range if they are found to be both damaging and highly host-specific. In addition to scientific literature searches, field surveys, and biological studies of weed natural enemies, research activities may also include taxonomic descriptions of new species and molecular genetic studies of weed and/or natural enemy populations, depending on one’s interests and expertise. My research program focuses on important weeds of the arid western United States, but I would also be interested in collaborating on a study of an invasive weed from the applicant’s home region, which they could then continue at their home university after their sabbatical ends. erin.scully@usda.gov, 785-776-2710 Researcher’s statement: My work focuses on improving genomic resources for stored product insects and identifying genes and mutations that are associated with the ability to detect and respond to pheromones, kairomones, and other volatiles and the ability to tolerate biotic and abiotic stresses. I use a combination of bioinformatics approaches, such as genome assembly, RNA-Seq, and proteomics, and functional genomics approaches, such as RNAi, to address these topics. I also have a broad range of expertise in plant, insect, and microbial genomics, bioinformatics, molecular biology, and plant-insect-microbial interactions. des.serba.@usda.gov; 520-316-6368 Researcher’s statement: Warm season turfgrass species are the integral component of sustainable landscapes and agroecosystems in the desert U.S. southwest. Our research is primarily focused on breeding and genetics to improve naturalized warm season grasses such as bermudagrass and zoysiagrass for drought and heat tolerance, adaptation to saline soil, and color retention in the mild winter of the region. We are also studying native grasses for their suitability for turf use and management. We are using conventional and molecular approaches integrated with high throughput phenotyping using UAV and proximal sensing devices. We conduct marker-trait association studies to identify candidate genes and genomic regions for key traits to facilitate selection using molecular markers. anna.testen@usda.gov, 330-641-2862 Researcher’s statement: Research in my lab focuses on developing sustainable disease management strategies for specialty crops produced in controlled environment agriculture (CEA) systems, ranging from high tunnels to vertical farms.

Sophisticated plant molecular biology techniques are developed and utilized to create useful molecular tools for precisely performing genome engineering in plants. Recently a highly effective gene stacking technology called GAANTRY was developed and shown to efficiently engineer 10 or more genes into plants. Also, a suite of novel promoters, terminators and insulator sequences have been identified that control green tissue-specific, root-specific, seed/fruit-specific and pollen- or reproductive-specific expression in plants. kristin.trippe@usda.gov; 541-738-4181 Researcher’s statement: The mild, marine climate in the Willamette Valley of Oregon supports a broad diversity of seed crop rotations, including grass, clover, meadowfoam, and hemp. Crop management practices within this production system are equally diverse. While some farmers employ conventional practices that involve frequent tillage and bailing of crop residues, other farmers use one or more practices that are thought to improve the health of the soil including returning crop residues to the soil, infrequent tillage, and frequent rotations. Little is known about how these differing practices effect soil health, soil microbiomes, or pest and pathogen populations. The aim of our research program is to deepen this understanding and to determine if conservation farming practices improve yield or decrease costs. joshua.udall@usda.gov; 979-213-0137 Researcher’s statement: Crop germplasm research focuses on cotton, pecan, sorghum, and warm season grasses.
