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.


Assistant Professor of Medicine

Husain Poonawala, MBBS, MD
Tufts Medical Center

I am an Infectious Diseases physician and Clinical Microbiologist at Tufts Medical Center. My research interests are in tuberculosis and non-tuberculous mycobacteria, and my work is focused on developing and integrating novel diagnostic methods into clinical care and public health interventions to improve outcomes from these infections. In 2023, I received a Translational Science Career Development (K12) Award through the Tufts CTSI . My work in the Aldridge Lab will aim to adapt the DiaMOND assay to develop a novel combination antimicrobial susceptibility testing method for Mycobacterium abscessus that can be used in clinical microbiology laboratories. This will allow the design individualized treatment regimens for this multidrug resistant pathogen that is often described as an “antibiotic nightmare.”


Postdocs 

Emmanuel Ogbonna, PhD

I am a joint postdoctoral fellow in the Aldridge Lab at TUSM and the Laboratory for Systems Pharmacology at HMS working with Dr. Peter Sorger. My research is on the pathogen Mycobacterium tuberculosis. I had previously studied putative targets for novel TB drugs, including essential cellular proteases. I am currently studying the relationship between granuloma heterogeneity and host immune response – elicited upon tuberculosis infection – using tissue cyclic immunofluorescence or t-CyCIF. CyCIF is used with a wide array of antibody markers to phenotype all the different cell types associated with the granuloma stages, especially their spatial relationships to one another. With these cell-cell associations assessed, it is then possible to understand physiological and immunological outcomes in the TB granuloma microenvironment.

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.

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.


Joshua Whiteley, Biomedical Engineering PhD Candidate

I am researching the morphological changes that occur when treating tuberculosis with antibiotics in different growth conditions to better understand drug mechanism of action.

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 dete​rmine how different lesion niches influence Mtb response to specific drug regimens.
