Clinic-Compatible Microfluidic for Carbapenemase Detection

My research focuses on developing machine learning-powered microfluidic diagnostics to rapidly detect carbapenemase-producing organisms (CPOs). By integrating colorimetric detection with ML algorithms, we achieve high-accuracy classification of antibiotic-resistant bacteria in minutes rather than days. Using recursive cross-validation and stratified k-fold methods, our optimized k-nearest neighbors (KNN) model reaches 100% accuracy for certain carbapenemase classes within just 5 minutes.

We are currently implementing deep learning for microfluidic image analysis, employing convolutional neural networks (CNNs) with transfer learning to automate classification from smartphone-captured images. This work is paving the way for faster, more accessible clinical diagnostics to combat antibiotic resistance in healthcare settings.

Sample Recovery Paradigm for Dengue Detection 

This research focuses on developing a novel clinical paradigm that preserves patient samples for comprehensive testing without sample depletion. The microfluidic-based platform allows for point-of-care antigen testing while maintaining sample integrity for additional downstream diagnostics. Initially targeting dengue virus detection using NS1 antigen, this approach has significant implications for resource-limited settings where maximizing diagnostic information from limited sample volumes is crucial. The technology enables healthcare providers to conduct multiple tests from a single patient sample, improving diagnostic capabilities without requiring additional specimen collection. 

F. tularensis Detection Using Magnetic Particles 

During my undergraduate research, I worked on enhancing the detection sensitivity of Francisella tularensis, the causative agent of tularemia. This project involved pre-concentrating F. tularensis lipopolysaccharide (LPS) using Invitrogen Dynabead M-270 Epoxy magnetic particles before analysis with lateral flow immunoassay (LFI). This approach aimed to improve diagnostic capabilities by increasing sensitivity with larger sample volumes. The significance of this work lies in developing an effective, affordable point-of-care diagnostic tool for tularemia, which is particularly valuable in outbreak scenarios or resource-limited settings.
