Position/title – Postdoctoral Research Fellow
Location – Texas A&M University at Corpus Christi, TX

Responsibilities – Two postdoctoral research fellow positions are available under the supervision of Dr. Jian Sheng in conducting a research project recently funded by Office of Naval Research, Department of Defense to study shear resistant biofilm in both laminar and turbulent flow regimes. Briefly, the goal of project is to use microfluidic and meso-scale experimentation to understand three environmental insults on the formation processes and 3D architecture of shear-resistant (SR-) biofilms, which are the ubiquitous phenomena over ship hulls. Three environmental insults investigated in the project are surface landscapes (e.g. surface energy landscape, structured roughness, and anti-fouling coatings such as rGO and GO), flow shear (laminar and turbulent), and phenotypes (especially those genes and pathways that regulate the production of extracellular polymer substance (EPS), and changes in its composition)

- The first fellow will be focusing on microscale mechanisms in which the aforementioned environmental factors affect SR-biofilm. He/she will be responsible for (a) development and integration of instrumentations and technologies that allow simultaneous 3D flow, cell mobility, biofilm rheology by particle tracking micro-rheology, and film structure via scanning epi-fluorescent, as well as film-surface adhesion by holographic interferometry. Note that all techniques have already been developed separately in Sheng’s lab. (b) conducting microcosm experiments using developed eChip platform under different flow shear separately or in combination with other factors. © assisting sample collection, preparation and analysis in phenotype identifications, isolation and functional analysis as well as mutagenesis.

Qualification: Experience with experimental studies of colloids using microfluidics technology is required. Skills and familiarity with one or several experimental measurement techniques such as microPIV, particle tracking micro-rheology, optical and fluorescence microscopy, are also required. Further experience in working with microbes including cultivation and experimentation, or in genetic analysis will be a plus. Although preferred, the willing postdoc will be trained on the fundamentals necessary to conduct his/her research responsibility. Support from in-house experts will be provided.
US citizenship is required for this position.

- The second fellow will be focusing on mesoscale experimentation on SR-biofilm in the realistic marine environment (i.e. turbulent flow and rough surfaces). He/she will be responsible for (a) establishing the biofilm-turbulent channel flow facility by modifying an existing closed-loop turbulent channel flow facility, (b) development of measurement suite integrating PIV, PLIF and Digital Holographic Interferometry. Note that all techniques are available in the lab, © conducting the mesoscale experiments at three Reynolds numbers using 1 bacterial isolate, & two natural consortia.
Qualification: Experimental experience with complex large-scale flow experiments is required. Skills and familiarity with flow measurement techniques such as PIV and/or PLIF, are also required. Proactive attitude towards new technologies and methodical approach to complex experimentation are needed for this position. Further experience in working with live microbial system will be a plus. Although preferred, the willing postdoc will be trained on these fundamentals necessary to conduct his/her research responsibility. Supports from in-house experts will be provided.
US citizenship is required for this position.

Qualified PhDs in one of the following disciplines: mechanical engineering, chemical engineering, biomedical engineering, civil engineering, environmental engineering, are encouraged to apply.

Available resources and environment: Sheng’s labs are located at Texas A&M University at Corpus Christi, a campus within 50 meters to the bay. Apart from the natural beauty of working environment, Sheng’s labs are equipped with the state-of-the-art facilities including an dedicated ISO-100 two-bay cleanroom with >$4M microfabrication equipment; nanomaterial characterization facility including dedicated AFM, FE-SEM, several Nikon microscopes, DSR, DLS; fully equipped BSL1 & BSL2 cell culturing and experimentation facilities; and a suite of flow characterization systems including Particle Image Velocimetry (PIV), Stereo-PIV, Tomographic-PIV, Planar LIF, Digital Holographic Microscope (DHM), Digital Holographic Interferometry (DHI) and dedicated HPC cluster. These resources provide support to bring the project to its full fruition.

Availability: Available immediately until filled.

Application – Send your application including CV, contact information a list of references, and several relevant publications to: Dr. Jian Sheng, at jian.sheng@tamucc.edu, or jian.sheng@austin.utexas.edu
