A.W Zaibudeen

A.W. Zaibudeen is a postdoctoral fellow at Rheology & Dynamic Light Scattering (Rheo- DLS) lab at Raman Research Institute (RRI). He joined RRI in October 2020 and has been working with Prof. Ranjini Bandyopadhyay on colloidal droplet drying. He completed his Ph.D. at Indira Gandhi Centre for Atomic Research (IGCAR), Kalpakkam, and worked at the Indian Institute of Technology- Bombay as an Institute postdoc fellow (IPDF) for a year.

Research work: I am working on controlling the kinetics of colloidal droplet evaporation and the evaporation- induced distinct pattern formation that contain diverse aggregations of nanoparticles. Currently, I am focusing on the formation and evolution of various drying-induced patterns and distinct gold nanorod aggregation in the dried deposit pattern by evaporating a droplet of gold nanorod dispersion under different physicochemical conditions. The formation of distinct dried patterns and the aggregation of nanoparticles in the same have broad applications in sensors, food contamination, diagnosis, optoelectronics, photonics, etc.

Chandeshwar Misra

Chandeshwar Misra has completed his graduation (2013) and post-graduation (2015) from Dr. R.M.L. Awadh University, Faizabad, Uttar Pradesh. After qualifying Joint Entrance Screening Test (AIR- 195) and Graduate Aptitude Test (AIR-635), he joined Raman Research Institute in 2016 to pursue his Ph.D. He has good team leader qualities. Sport, music, reading, movies, and other activities are among his interests.

My current research interest is studying the jamming dynamics of soft colloids in aqueous suspensions. I synthesize various colloidal particles like poly(N-isopropylacrylamide) (PNIPAM) particles of different sizes and stiffnesses and thermoresponsive core-shell particles with core and shell having different lower critical solution temperatures. I use the techniques like dynamic light scattering, rheology, rheo-dielectric, and scanning electron microscopy to study the dynamics of these colloidal particles and their microstructure in aqueous suspensions.

Rajkumar Biswas

Before joining RRI in 2016, he completed his bachelor’s and masters in Physics from St. Xavier’s college, Kolkata and Indian Institute of Technology, Guwahati (IITG) respectively.His research focuses on rheological and dynamical properties of different soft matter systems. He has worked on various projects which includes rheological studies of Laponite gels using falling ball viscometer and optical tweezer. Along with that, he has been studying the dynamical heterogeneities in colloidal and granular systems.
