Few people are capable of expressing with equanimity opinions that differ from the prejudices of their social environment. Most people are even incapable of forming such opinions." - The New Quotable Einstein
need to overcome the idea, so prevalent in both academic and
bureaucratic circles, that the only work worth taking seriously is
highly detailed research in a speciality. We need to celebrate the

# Speaker: Dr. Heiko Enderling, H. Lee Moffitt Cancer Centre & Research Institute, at IST 17:30 HourTitle: Integrating Computer Modeling of Cancer into Patient-specific Clinical Decision Making
Abstract: In close collaboration with experimentalists and clinicians, mathematical models that are parameterized with experimental and clinical data can help estimate patient-specific disease dynamics and treatment success. This positions us at the forefront of the advent of ‘virtual trials’ that predict personalized optimized treatment protocols. I will discuss a couple of different projects to demonstrate how to integrate calculus into clinical decision making. First, we show that a mathematical model can be calibrated from early treatment response dynamics in patients undergoing hormone therapy for prostate cancer. The learned model dynamics can then be used to forecast responses to subsequent treatment, and identify high risk patients who would benefit from concurrent therapies. In a second example, I will discuss how the pre-treatment tumor-immune ecosystem can be predictive of radiotherapy outcome, and how we can prospectively simulate treatment response dynamics to identify patient candidates for radiation dose escalation when needed, and treatment de-escalation without jeopardizing outcomes.

Title: A System Biology Based Dynamic Model to Limit Uncertainty in Cancer Treatment
Abstract: In present cancer treatment scenario different chemotherapeutic strategies like Maximum Tolerable Dosing (MTD), Metronomic Chemotherapy (MCT), Antiangiogenic (AAG) drug, Hematopoietic stem cell transplantation are available; however, the selection of the best therapeutic strategy for an individual patient at any particular stage of disease remains uncertain till now. Several analytical models are proposed for each of the chemotherapeutic strategies; however, no single analytical model is available that can make a comparative assessment of the long-term therapeutic efficacy among these strategies towards patient specific manner. To address this issue we developed a composite synergistic system (CSS) model. Here we have synergized the output of two models. One is based on fluid dynamics (FD) principle and another is based on vasculature growth (VG). In this developed model considered model variables are helpful for fitting of initial clinical data of individual clinical cases and successive model simulation runs may help in making therapeutic decision/prediction. Again tracking tumor growth at a regular interval of time is possible by matching the simulation output with available clinical techniques like MRI or simple blood testing. Such model may help the clinician to overcome the uncertainty in therapy design at an individual patient level.

Title: Artificial Intelligence and Multiscale Modeling of Tumor Treatments
Abstract: From the perspective of systems biology tumor can be regarded as a complex adaptive system. It is a nonlinear system, composed of a number of dynamically interacting elements with complex feedbacks between them. To model such systems multiple scales should be taken into account. Molecular scale simulations can give us insight into structural, thermodynamic, kinetic and other properties of applied drugs and how those drugs interact with cell membrane and receptors. At the cellular scale, pharmacodynamics modeling simulates the efficacy and toxicity of drugs. At the tumor scale, we need to integrate findings from the molecular and cellular scale simulations with the heterogeneous and adaptable tumor structure. To model tumor adaptive dynamics and the resulting emergence of treatment resistance, we should incorporate individualized genotype and phenotype data. Finally, at the organism scale, we should use integrated PK/PD approaches to model bio-distribution and clearance of drugs, as well as whole-body physiologically based pharmacokinetic models (PBPK). The set of all possible configurations of such modeling effort is enormous. Computationally investigating all of them is not feasible approach. However, with Artificial Intelligence we can speed-up and automate the search for optimal treatment strategy. In this webinar we will discuss strategies for developing such multiscale modeling platform and how it can be integrated with artificial intelligence.

Title: Machine Learning for Designing Hard Tissue Prostheses
Abstract: To improve the performance of the orthopedic and dental implants, i.e. to improve several properties simultaneously, the constituent biomaterials properties as well as implant structure needs to be designed judiciously. The choice of the parameters for achieving optimum performance of the systems is difficult to arrive experimentally, as the process becomes expensive and laborious. In silico approaches hold promise for searching the solutions for achieving the target performance. Among the many approaches of designing materials and structures for protheses computationally, machine learning attempts to map the hidden relationship between the variables of complex, nonlinear systems using available information of the system in a high-throughput, statistically robust, and yet physically meaningful manner. Machine learning tools, e.g. artificial neural network and neuro-fuzzy inference systems are increasingly used in the domain of informatics-based design of implants and biomaterials. In a prescriptive analytics approach for improving several properties together, many of them having conflicting objectives, the developed models are used as objective functions for optimization with genetic algorithm used in single as well as multi-objective mode.
