Biography

Kolachalama laboratory research areas:

1. AI for precision medicine
Artificial intelligence is poised to help deliver precision medicine, yet achieving this goal is nontrivial. Machine learning and image processing techniques along with developments in software and hardware technologies allow us to consider questions across scales. We leverage these tools for pattern recognition and understanding pathophysiological mechanisms that would pave way towards developing biomedical technologies that are of diagnostic and prognostic relevance.

2. Computational pathology
Machine learning and image processing algorithms are transforming the way by which medical images are analyzed to uncover hidden patterns and facilitate patient diagnosis as well as to improve the delivery and effectiveness of patient care. This is especially the case in the field of digital pathology where several researchers are employing these powerful techniques to address specific questions in a spectrum of disease scenarios. We develop computational frameworks for quantitative assessment of tissue biopsies and to assist the pathologist.

3. Mechanisms of endovascular therapies
Obstructive arterial disease remains a clinical challenge. We use a multidisciplinary approach that leverages biophysical and bench-top models to understand the mechanisms of endovascular therapies. Previous studies by us and our collaborators have explained the role of physiologic factors in modulating spatiotemporal arterial distribution patterns for drug-eluting devices as a function of intrinsic device design, relative device position and pulsatile nature of blood flow. We have extended models simulating idealized settings of physiology to real world issues and further examine arterial tissue response that varies due to procedural settings, device composition, arterial wall ultrastructure and disease, physiologic changes within complex vascular anatomies, vascular injury and the mode of drug delivery.
