Govind V Kaigala's Biography

Govind V Kaigala, Research Staff Member, IBM Research Laboratory-Zurich

Dr. Govind Kaigala is a Research Staff Member at the Laboratory of IBM in Zurich. He is currently leading activities on liquid-based non-contact scanning probe technologies – microfluidic probe – and is championing concepts on “open space” microfluidics and “tissue microprocessing”. These research activities are driven by specific needs in the fields of pathology and personalized medicine. He is passionate about translational clinical/medical research and strives to bring in quantitation in biology by leveraging micro- and nanosystems assays for microchip-based chemical and biomolecular analysis.

Previously, he was an NSERC postdoctoral fellow at the microfluidics laboratory in Mechanical Engineering and Urology at Stanford University, USA. Dr. Kaigala received his Ph.D (Electrical Engineering and Oncology) and M.Eng from the University of Alberta, Canada. Dr. Kaigala has authored and co-authored 44 scientific publications, 70 conference papers, 1 book, and 30 patent families. In addition to IBM and other industrial entities, his work is supported by the European Research Council (ERC), the European Union and Swiss National Science Foundation. He is the recipient of several IBM awards, including Research Division Accomplishment Award in 2014 & 2017, the Horizon Alumni Award from the University of Alberta, and he is a Senior Member of IEEE.

In contrast to standard microfluidics, which are typically closed, we are developing a scanning, non-contact microfluidic technology that can shape liquids in the "open space" over surfaces. This technology utilizes a microfluidic probe (MFP) having microfabricated structures for localizing a liquid of interest on a surface using hydrodynamic flow confinement. MFP permits patterning surfaces with proteins and other biomolecules in an additive and subtractive manner, forming complex gradients on surfaces, and interacting with cells on surfaces. With flow confinement operating at volumes smaller than 1 nanoliter, a few cells can be targeted in a human tissue section for the specific staining of disease markers.  This confinement concept has also been scaled for targeting 1000’s of cells. Flow confinement and efficient use of chemicals can be further optimized using a concept called "hierarchical" hydrodynamic flow confinement.  I will show how this family of liquid scanning probe devices is evolving as a bioanalytical tool to alter the physics and chemistry of biological interfaces at the micrometer to centimeter-length scales. I will also propose concepts pertaining to tissue microprocessing encompassing local phenotyping for interrogating tumor heterogeneity and spatially resolved molecular profiling which may contribute to the multi-modal analysis of critical biopsy samples in the context of next-generation pathology.
