Background
Joel Krehbiel graduated from Bethel College in Kansas in 2006 with a Bachelor's Degree in Math and Physics. He came to the University of Illinois and obtained a Master's Degree in Mechanical Sciences and Engineering in 2008. After graduation he spent a year with a relief and development organization building biodigesters in rural Brazil. Through this experience he developed a passion for bioenergy research. He returned to graduate school in 2010 to pursue a Ph.D. in Mechanical Sciences and Engineering. Joel is currently researching mechanical algal cell disruption techniques for improved biodiesel production.

StrainSelection

Joel's recent research has focused on ultrasonic cavitation (TOP, MIDDLE) to disrupt algal cells (BOTTOM) for oil extraction.

Research
Joel's current research focuses on the following areas:

  • Energy balance for cell disruption of algae and algal oil potential
  • Disruption of cyanobacteria with ultrasound
  • Shear effects of viability of algae
  • Rapid decompression of algae to extract oil
  • Model of disruption of cyanbacterial gas vesicles with ultrasound
Previous work has included:
  • Energy requirements for greenhouse production for early season vegetables
  • Greenhouse gas emissions from a single family biodigester
  • Digital image correlation for detection of basal cell carcinoma tumors
