Our research is primarily curiosity driven, where we take an engineering and physics based approach to explore biophysical processes occurring at the micro-scale. We then harness these principles towards applications pertaining to global health, bioengineering, and educational outreach. An overview of projects are described below:
Physics of Micro-scale Flows
Fluid flow arising due to thermal gradients (thermal instability driven convective flows) is quite ubiquitous in nature (oceanic currents, cloud formation, etc.) but they can exhibit unique characteristics at the micro-scale, capable of greatly accelerating biomolecular transport and reactions. We use computational tools (Computational Fluid Dynamics) and novel experimental setups (automated microfluidic systems) to study these flow states and evaluate the conditions under which they can be harnessed to actuate biomolecular transport and assembly, accelerate DNA replication and separate cells (based on their shape and size).
Point-of-Care Detection for Global Health
The recent disease outbreaks have exposed some key limitations facing current infectious disease management strategies, particularly when applied in remote underdeveloped areas. Existing approaches are highly resource intensive, relying on dispatching specially trained personnel to isolated locations where biological samples are collected and returned to dedicated laboratories for analysis. A need therefore exists for inexpensive and robust tools that can be broadly deployed to accelerate diagnosis, enable pinpoint delivery of therapeutics, and provide real-time data to better inform decision making. We engineer simple and portable diagnostic tools (such as smartphone based DNA analyzer and lab on a drone) that can be deployed and operated outside the laboratory to address global challenges of healthcare, environmental sampling, agriculture and science outreach. Projects under this area are quite multidisciplinary and collaborative in nature.
Microfluidics enables large-scale automation in chemical and biological sciences, suggesting the possibility of numerous experiments performed rapidly and in parallel while consuming little reagents. This has led to the emergence of the so-called lab on chip systems, making significant strides in diverse areas ranging from grand challenges such as water purification to fundamental research such as genetic analysis. Despite significant advances, few roadblocks has hindered microfluidic systems from replacing convectional bench-top analytical tools and widely penetrate the point of care in low resource settings where they are needed most. We aim to create the next generation of microfluidic devices using rapid fabrication techniques (3D printing, micro-milling and laser cutting) that would drastically simplify the prototyping and assembly processes of microfluidics systems.
We have a few positions open for passionate postdoctoral, graduate (prospective PhD/Master’s applicants) and undergraduate students. Our research is quite multidisciplinary, involving researchers from a wide range of background including engineering (chemical, mechanical, biomedical, electrical and bioengineering), applied physics, biophysics, material science and applied mathematics. Along with frequently publishing our research, we actively explore platforms to commercialize the technologies that are developed in our lab.
