Shweta Jatav

Assistant Professor
PhD (Chemical Engineering), IIT Kanpur
Areas of interest
Rheology, Colloidal suspensions, Viscoelasticity, Complex materials

Shweta Jatav joined School of Engineering and Applied Science as an Assistant Professor in 2017. She graduated in Chemical Engineering from Institute of Engineering and Technology, Lucknow in 2009. Afterwards she pursued M.Tech from IIT Roorkee followed by Ph.D. from IIT Kanpur in Chemical Engineering. Her Ph.D. work was focused on phase behavior of anisotropic shape colloidal clay nanoparticles in aqueous media. During her stay at IIT Kanpur she was also working as Research Associate for industrial projects.

Awards

1.   The Society of Rheology Travel Grant for the XVIIth International Congress on Rheology (ICR2016), Kyoto, Japan.

2.   DST travel grant for 10th Annual European Rheology Conference (AERC- 2015), Nantes, France.

3.   Cash award from IIT Kanpur for publication Chemical stability of Laponite in aqueous media. Applied Clay Science, 97–98(0): 72-77.

The major research interests of Shweta are to explore the structural properties and flow behavior of complex fluids using rheology. 

Complex fluids such as paints, food products, personal care products, crude oil, slurry and polymers etc. exhibit viscoelastic properties, like shear thinning, thixotropy, yield stress, time dependent aging. These properties can be explored by performing different rheological experiments such as frequency sweep, strain sweep, stress relaxation, creep, oscillatory stress/ strain etc.

Soft materials (complex fluids) share different types of interparticle interactions such as electrostatic interactions, van der Waals attractive interactions, chemical bonds etc. Consequently, such systems possess variety of microstructures resembling different phases e.g. sol, gel, glass, and liquid crystal etc. The prime emphasis is to study different phases of complex fluids and to eliminate existing problems of stability, flow behavior, processing of such systems.
