Post doc position/Senior RA, multiple positions (Hong Kong): The Hong Kong Oyster Hatchery and Innovation Research Unit (HKO_HIRU) at HKU is seeking researchers to investigate stress-induced omics and their transgenerational expression, as well as the genomic selection of multiple stress-tolerant strains in Hong Kong oysters. As part of this initiative, they are recruiting 3 post docs and/or Senior RA. These positions are available immediately. The primary goal of these positions is to 1) develop tools for genome-based breeding of the Hong Kong oyster, a major aquaculture species in China – which is accounting almost ¼ of global production. Specifically, they will focus on the application of SNP genotyping platform in genomic selection for high salinity tolerance and disease resilient strains, 2) identify a scientifically innovative and practically feasible ways to improve taste and meat quality of oysters (food and sensory chemistry) via fattening processes during harvesting winter period, and 3) Identify microbiological and environmental factors involved in oyster mass mortality at the time of harvest in winter period using metagenomics and other omics and environmental techniques. These positions, in close collaboration with PhD students and others in the lab, may involve in hatchery production and maintenance of experimental oysters, conducting challenge experiments, analysis of genotype, microbiome, environmental and phenotype data, communication with growers and the oyster community around south China, and importantly, writing manuscripts for publication. Interdisciplinary International collaboration is KEY strength of their group. Qualifications: PhD degree in a related field. Applicants should have relevant research experience and a good publication record. Experience in genomic selection, food chemistry, or environmental microbiome is highly preferred. The monthly salary ranges from HK$25,000 to 35,000 (approximately US$3 to 4K per month), commensurate with publication record and potential to become an academic professor or scientist in the near future. Income tax in Hong Kong is negligible for this salary range. The exact salary and contract duration are negotiable.
