Research Assistant Professor
I use a combination of fluorescence microscopy, omics style data, and machine learning to understand how environmental signals influence the essentially of different biochemical pathways in Mtb. Using antibacterials to inhibit specific cellular processes, I am investigating how perturbations to one or more pathways contribute to Mtb cell death across different physiological states.
My work focuses on understanding how M. tuberculosis controls its growth and behavior under different growth conditions and antibiotics.
Kathleen Davis, PhD
I collaborating with members of the Levy CIMAR and Tufts Medical Center to develop a method of in-vitro testing of drug regimens on bacterial pathogen clinical isolates from hospital patients with severe infections. The goal is to design in-vitro testing methodology to help choose more effective regimens for serious infections. My other work includes a multi-institution collaborative effort to identify small molecules that can be used in combination with antibiotics to restore or improve the activity of those antibiotics against community- and hospital-acquired bacterial infections.
Lesion heterogeneity is the hallmark of tuberculosis and has made it difficult to treat. I am working to help develop experimental-computational approaches to model drug response in different lesions to identify better drug regimens to treat tuberculosis.
My current work has two major aims: 1) Understanding how the growth conditions in TB lesions alter the metabolic state of M. tuberculosis and perpetuate anti-TB drug tolerance through high-throughput image analysis; 2) Using multi-omics data and machine-learning to characterize anti-TB drug mechanism of action in disease-relevant growth conditions.

I am working on DiaMOND (diagonal measurement of n-way drug interactions) based projects to build predictive models of in vivo outcomes using in vitro measurements. The predictions can then be used to better inform effective drug combination to be tested clinically. In my free time I like to read, bike, swim, surf and enjoy other outdoor activities.
Maliwan Kamkaew, MSc
I completed my MSc in Molecular Genetics and Genetic Engineering from Mahidol University, Thailand. During that time, I completed a Laboratory of Systems Pharmacology internship at Harvard Medical School where I became interested in live-cell imaging and single-cell analysis. Currently, my research focuses on using live-cell imaging and single-cell analysis to study the adaptation of Mycobacterium tuberculosis under different environments.

Mycobacterium tuberculosis has the ability to persist within lesion with different stressors present. These stressors are thought to be responsible for Mtb survival and drug tolerance. We aim to develop in vitro models using lesion-specific stressors to determine how different lesion niches influence Mtb response to specific drug regimens.
Tracy Washington, PhD
I’m a senior at Tufts University School Of Engineering studying Biomedical Engineering, with minors in Mathematics and Computer Science. At the Aldridge Lab, I work on developing deep-learning-based image segmentation tools for live-cell microscopy and developing novel analysis tools for understanding cellular growth heterogeneity in M. tuberculosis and M.smegmatis.
