It develops an implicit solvent approach for aqueous–solution molecular dynamics and quantum-mechanics modeling, and introduces electrostatics-driven ensemble learning for pKa prediction. A transferable meta-learning framework is proposed for single-cell mass spectrometry phenotype prediction with limited melanoma samples. Finally, it reports a bioengineered bacterial flagella templating route to synthesize polycrystalline Co3O4 nanowires for gram-negative antibacterial applications.","UNIVERSITY OF OKLAHOMA GRADUATE COLLEGE  \nMACHINE LEARNING ASSISTED MOLECULAR SIMULATIONS / MASS SPECTROMETRY DATA ANALYSIS AND RATIONAL DESIGN OF  \nANTIBACTERIAL Co3 O4 NANOWIRES FLAGELLA  \nA DISSERTATION  \nSUBMITTED TO THE GRADUATE FACULTY in partial fulfillment of the requirements for the Degree of DOCTOR OF PHILOSOPHY  \nBy  \nSONGYUAN YAO  \nNorman, Oklahoma  \nMACHINE LEARNING ASSISTED MOLECULAR SIMULATIONS / MASS SPECTROMETRY DATA ANALYSIS AND RATIONAL DESIGN OF  \nANTIBACTERIAL Co3 O4 NANOWIRES FLAGELLA  \nA DISSERTATION APPROVED FOR THE CHEMISTRY AND BIOCHEMISTRY DEPARTMENT  \nBY THE COMMITTEE CONSISTING OF  \nDr. Yihan Shao, Chair Dr. Bin Wang  \nDr. Si Wu  \nDr. Bayram Saparov  \n© Copyright by SONGYUAN YAO 2023 All Right Reserved.  \niv  \nAcknowledgements  \nI am deeply appreciative to everyone who contributed to my PhD thesis.
