Recent News:

  • Journal article co-authored by former group member, Dr. Eyyub Kibis, and Dr. Büyüktahtakιn Toy has been accepted for publication by Mathematical Biosciences. The article titled  “Optimizing Multi-Modal Cancer Treatment under 3D Spatio-Temporal Tumor Growth” integrates the spread of cancer cells into a 3D spatio-temporal reaction-diffusion model of cancer growth, while taking into account therapeutic (surgery, chemo-, and radio-therapy) effects to minimize the number of new cancer cells (10/25/2018).


  • SODAL receives funding from USDA Forest Service. Dr. Büyüktahtakιn Toy serves as the lead PI of the team with collaborator Dr. Robert Haight from the US Forest Service, for a $58K grant to address risk-averse resource allocation challenges to protect community forests from the threat of EAB.
