Multiple research associate and postdoctoral fellow positions as well as PhD student positions with Graduate Research Assistantship (GRA) are available immediately in the Oklahoma Center for Respiratory and Infectious Diseases (https://ocrid.okstate.edu/) and the Department of Physiological Sciences at Oklahoma State University to study host-pathogen interactions with a focus on influenza virus, SARS-CoV-2 and/or mycobacterium tuberculosis, pathogenesis of lung diseases (IPF and COPD), and stem cell therapy and human lung tissue modeling. Major techniques used in the lab include high throughput analyses (bulk and single-cell RNA-seq, spatial gene profiling, proteomics and genome-wide CRISPR library screen), gene knockout/down and overexpression (CRISPR/Cas9, RNA interference and molecular cloning), gene and protein quantitation (droplet digital PCR, real-time PCR, Western blotting and immunostaining), biochemical, molecular and cellular techniques, knockout and transgenic mice and various animal models. Candidates will have opportunities to learn various advanced technologies, develop professional career skills including presentation, networking and grant writing and collaborate with research faculty, postdoctoral fellows and PhD students in the lab. The candidates who are interested in joining a dynamic, collaborative and interdisciplinary research group and who are responsible, dedicated, self-motivated and hard-working are encouraged to apply. Interested candidates are requested to email their CV/Resume to Dr. Lin Liu, Regents Professor and Director at lin.liu@okstate.edu.
