Biomedical research is becoming increasingly dependent on construction and simulation of computational models.Arguablythiswillbeevenmorethecasewiththedevelopmentofpersonalizedmedicine.However, thetechnicalaspectsofmodelingandsimulationareoverwhelmingtomanybiomedicalresearchers.Whatis neededisasoftwareapplicationcapableofprovidingtheappropriatenumericalalgorithms,butshieldedbya user interface that aides the biomedical researcher in conducting the required simulations. Modeling and simulation can be applied at the level of molecules, their networks, cells, tissues and whole organisms. Sometimesseveraloftheselevelshavetoberepresentedinordertoproperlypredictandunderstandhealth and disease. Thus models are becoming larger, multiscale, and require various different mathematical frameworks for simulation. We propose to address this need with continuing development of the COPASI software,whichisalreadywidelyusedinthebiomedicalresearchcommunity,addressingthecurrenttrends. ThisprojectwillalsoprovidesupporttothevibrantcommunityofCOPASIusers/biomedicalresearchers.We willaddressthiswiththefollowingSpecificAims:
Aim1.

Aim2. ImproveCOPASI?suserinterfaceandtheinterfaceswithothersoftware.Wewillimprovethegraphical user interface to allow it to efficiently manipulate very large models. We will create a new programming interfacesothatotherscaneasilyuseCOPASI?sfunctionsfromotherprograms.

Aim 4. Support the modeling community. We will continue outreach program activities aimed helping biomedicalresearchersmakefulluseofthesoftware?scapabilities.Thisincludescontinuingtooffertutorials, courses,andworkshops?tocreatefurthertrainingvideosandtomaintainawebbaseddiscussiongroup.
This research will focus on developing and maintaining the COPASI software, a tool for studying complex biological systems, including human disease models, through computer simulation. COPASI will facilitate knowledge discovery using computer simulations that are important in health and disease, including drug design,andpersonalizedmedicine.Useofthissoftwarewillbeavailabletoallbiomedicalresearcherswithout limitationandwillcontributetounderstandinghowdiseasesdevelopandhowtheycanbecured.
