All of these perspectives are critical to surmounting the challenges of precision medicine.
Their integration has the potential to lead to fundamentally new methodological advances, accelerating progress toward widespread deployment of precision medicine in practice. This will require mathematical, statistical, and computational scientists to forge new, deep collaborations among themselves and with biomedical scientists. This SAMSI program facilitated this critical interdisciplinary exchange by bringing together leading mathematical, statistical, computational, and health sciences researchers to pursue innovative, data-driven methodology for precision medicine.
The program fostered these interactions through workshops, opportunities for long- and short-term visitors, and theme-focused working groups that meet regularly by video-conference, allowing ongoing collaborations among non-resident participants. Program Poster.

Visiting Research Fellows. More sophisticated statistical, algorithmic and numerical methods are needed to analyse datasets with complex biological and clinical information.
Significant progress will be made if separate models of the disease process — operating at different levels and spanning a range of timescales — can be combined. The collection and storage of biomolecular and clinical information is more accessible and cheaper than ever. A major challenge now is to make sense of the vast volumes of data being produced, which is where complex computational models can play a vital role. Advances in technology and the development of new experimental methods have had a significant impact on the study of disease.
Computational analysis and modelling can help make sense of the data being collected.
Initially, molecular fingerprints can be used to identify biomarkers that signal an elevated risk of acquiring a disease or to confirm diagnosis. Information about intracellular processes can be used to construct artificial networks of the molecular interactions involved and evaluate their role in the disease, while more complex quantitative dynamic models can track the underlying molecular processes over time.
Such networks might also help to predict both the likely course of a disease and its response to treatment 2. Maintaining and analysing databases of disease-specific information will require significant computational resources. Although these strategies are promising, research is at a relatively early stage and there are many issues to be resolved. The range of disease-specific data being collected on a systematic basis needs to be increased.

Zhang, Hongmei University of Memphis. Forzenigo, A. She has been working on several interdisciplinary problems in optimization theory, control theory, machine learning, and power systems.
More information should come from longitudinal studies, in which samples or patients are followed over time. These data should be of high quality and suitable for comparison; many newer technologies are prone to experimental variation, limit-ing their utility in the clinical setting.
Accordingly, it is important to have com-putational models that can distinguish technological variation from true biological difference. Another major challenge relates to the difficulties researchers can encounter when seeking access to clinical data and relevant biological samples. Numerous legal and ethical issues related to privacy and personal data protection must be addressed — along with many organizational issues — if this situation is to improve. Researchers need reliable, accurate and trustworthy statistical tools to deal with the information being generated.
It is too easy for false-positive results to be produced from small samples of complex data. Similarly, without sophisticated statistical techniques, it is impossible to incorporate elements of chance into dynamic processes. The technologies used to visualize the results of modelling activities are equally important; they must be user-friendly by displaying results in a way that can be readily understood by fellow scientists and medical colleagues.
The intuitive nature of these visual presentations is critical when studying complex biological systems. The models must be updated regularly to keep up with the rapid evolution of infectious agents. Interactions between a pathogen and its host.

A modelling approach based on molecular networks can reveal information about the relationship between a pathogen and its host 9. The development of dynamic models that show how infectious agents replicate within cells will be an important step forward, as will quantitative descriptions of pathogenic spread throughout tissue and organs.
