Jha Laboratory
Laboratory Focus
Our laboratory focuses on developing a precision medicine approach to clinically important secondary injury processes like brain swelling and hemorrhage progression after acute brain injury. We are interested in these pathways because they are commonly encountered clinically and have a devastating impact on death and disability after multiple different types of acute brain injuries like traumatic brain injury (TBI), subarachnoid haemorrhage, and stroke. Our translational work in preclinical and clinical models spans a spectrum of single cell research, human biofluid markers, imaging, and genetics. One key focus of our laboratory has been using a translational approach to advance the understanding of the promising sulfonylurea-receptor-1 (SUR1) pathway in acute brain injury.
We are grateful collaborate on these projects with several phenomenal research groups and consortiums globally, including the University of Pittsburgh, Arizona State University, University of California – San Francisco, GAIN, TRACK-TBI, and CENTER-TBI.
Active Research Projects
The host response to TBI is highly individual and responsible for a large proportion of outcome variability. This includes several secondary injury processes like cerebral edema, intracranial hypertension, and contusion expansion that are key determinants of both survival and disability after TBI. Our research seeks to understand if and how genetic variability affects these processes.
We are evaluating single nucleotide polymorphisms, epigenetic, as well as gene expression. Initial work focused on SUR1-related pathways and has expanded to include both unbiased and Bayesian assessments.

We leverage known mechanisms of underlying pathobiology (for example SUR1) to evaluate and develop prognostic and predictive biofluid and imaging markers of related mechanistic endotypes (like hemorrhage progression) and thereby advance precision medicine. We also are actively evaluating sex- and age-based differences in pathophysiology using in vitro cell-based experiments, organoid models, and clinical biofluids from several types of acute brain injury with a focus on TBI and aneurysmal subarachnoid haemorrhage.

We use preclinical models of controlled cortical impact (CCI), CCI with hemorrhagic shock, and mild-repetitive closed head injury to model clinically relevant scenarios of TBI, such as contusion or repeated athletic injuries. These models are used to study important downstream pathophysiological effects (cerebral edema, intracranial hypertension, hemorrhage progression) as well as evaluate treatments. As with our clinical research, we are actively investigating sex- and age- based differences at multiple levels: single cell, imaging, protein expression, and behavioural and cognitive outcomes.
