TADESSE LAB

Welcome to the
Tadesse Lab

Our Research

Diagnostics Anywhere

Rapid, accurate disease diagnosis, and real-time monitoring is essential for effective treatments, halting the rise of drug resistance, and achieving personalized health and precision medicine goals. The Tadesse Lab develops next generation point-of-care diagnostic devices using optical, spectroscopy and nanoscience-based tools with machine learning based data analysis for application in resource limited clinical settings including developing nations, extraterrestrial exploration, and military sites. We aim to establish a leading research program for translational medicine integrating sensing technologies, artificial intelligence tools and needs-based design thinking for translation to targeted clinical and research settings.

Our Publications

We present surface-enhanced Raman spectroscopy (SERS) combined with machine learning (ML) as a powerful tool for providing interpretable insights into the transcriptome, proteome, and metabolome at the single-cell level. Recent advances in nanophotonics enhance Raman scattering for rapid, strong label-free spectroscopy, while ML approaches enable precise spectral analysis.

We present a rapid, culture-free, and antibiotic incubation-free drug susceptibility test for tuberculosis (TB) using Raman spectroscopy and machine learning. Recent developments in these techniques allow us to achieve over 98% accuracy in classifying resistant versus susceptible Mycobacterium tuberculosis (Mtb) strains on dried samples, and approximately 79% accuracy on patient sputum samples.

We present a novel approach using Sharpness-Aware Minimization (SAM) to address current limitations in Raman spectroscopy for antibiotic resistance testing. By enhancing model generalization and optimizing hyperparameters across diverse datasets, SAM achieves significant accuracy improvements—up to 10.7% on individual splits and an average increase of 2.5% across all splits—compared to traditional methods like Adam.

August 2023

Getting results from a blood test can take anywhere from one day to a week, depending on what a test is targeting. The same goes for tests of water pollution and food contamination. And in most cases, the wait time has to do with time-consuming steps in sample processing and analysis. 

Now, MIT engineers have identified a new optical signature in a widely used class of magnetic beads, which could be used to quickly detect contaminants in a variety of diagnostic tests. For example, the team showed the signature could be used to detect signs of the food contaminant Salmonella.
