  • Development and application of mechanism-based models.
  • Simulation of biological processes including subcutaneous insulin absorption and pulsatile insulin secretion.
  • Modeling of physiological regulation, such as pressure and flow in nephrons.

    • Main Results:

    • Demonstrated the consistency of assumed hypotheses with observed system behavior.
    • Examined system sensitivity to parameter variations.
    • Provided insights into processes not amenable to direct experimentation and predicted system behavior under novel conditions.

    Conclusions:

    • Mechanism-based modeling is a powerful tool for understanding biological systems and disease mechanisms.
    • This approach is directly applicable to improving the treatment of complex conditions like diabetes and hypertension.
    • A deeper understanding of biological regulatory mechanisms, facilitated by modeling, is essential for effective drug development.
