Okuno's Research Team

We perform fundamental and applied research on sustainable energy ecosystems, including subsurface energy resources and carbon capture, utilization, and storage (CCUS).  I am the director for the Energi Simulation industrial affiliate program on carbon utilization and storage (ES CarbonUT), which serves as a catalyst for practical solutions to the energy transition. 

​Research Job Openings

Posted December 7, 2023
We are seeking highly motivated individuals to join our research team in CCUS and EOR. Two openings are as follows:

Lab-experimental research

The successful candidate will perform laboratory experimental studies on carbon capture, utilization & storage (CCUS) and enhanced oil recovery (EOR); e.g., enhanced carbon storage, CO2 mineralization, rock-fluid interactions in CCUS and EOR, gas/solvent EOR, tight oil/gas recovery, thermodynamics, and equation of state. Desired skills/knowledge include high-pressure/high-temperature PVT, HP/HT coreflooding, and analytical instruments for chemical/material characterization.  

Numerical modeling research

The successful candidate will perform computational studies on the topics listed above; in particular, we would be most interested in working with an experienced modeler in thermodynamics and interfacial science. 

These positions require excellent English proficiency (written and spoken). A starting salary depends on the candidate’s qualifications.  The title can be postdoctoral fellow, research associate, or research engineering/scientist.
