Course Projects
Application of a Hybrid Neural Network-Mechanistic Model on Genome Scale Metabolic Model of Vibrio natriegens, Demonstrated a novel published model can predict accurate flux-balance-analysis simulated fluxes in a new scenario on a model of Vibrio natriegens (instead of publlished model of E.colli). Predicted flux-balance-analysis simulated growth rates on an independent test set with regression and validation coefficients of 0.74 each. Conducted limited hyper-parameter sweep by varying nodes in single hidden neural layer and hidden dimensions. Showed applicability and advantages of combining white-box and black-box models in a new scenario., Hybrid Modeling, Neural Networks, Mechanistic Modeling, Hyper-Parameter Optimization
Cellular-Automata Model for Cancer Tumor Growth Dynamics, Simulated five virtualization scenarios of tumor growth dynamics as published in a paper. Showed advantages of a stochastic cellular automata., Dynamical Modeling, Simulation Design, Cellular Automata Modeling, Stochastic Modeling
Database (SQL) Development for Protein Inventory, Created Entity Relationship Diagram for the conceptual design using MySQL Workbench. Created logical design for the Entity Relationship Diagram. Implemented Entity Relationship Diagram to create relationships using MySQL. Wrote queries in MySQL for data retrieval., Planning, Designing, Data Modeling, Implementation
Database (MongoDB) Development for Volume Electron Microscopy Metadata, Developed a logical database design for MongoDB (NoSQL database). Applied the design in python to create two databases for two different microscopes. Created a simple user interface and queries using python. Created a system for automated export of instrument level and run level metadata., Planning, Designing, Data Modeling, Implementation
