Apurba Paul - About Me

Currently, I am working as a postdoctoral research associate at the Department of Electrical Engineering of University of Notre Dame, Notre Dame, IN, USA under the supervision of Prof Gregory Timp.

My current research to study and use the time shared optical trap of 3D array in optical tweezers.

I am a former Postdoctoral Fellow of Department of Physics and Astronomy, Clemson University. I have worked with Dr. Joshua Alper, Prof. Kimberly Paul and Prof. Lukasz Kozubowski, where I have worked on various projects including the study of the biophysics of trypansomes motility, septin circular-collar formation, dissociation of biological bonds and the motility of variant surface glycoprotein (VSG) on trypanosomes surface.

I have done my Ph.D. from Department of Physics, Indian Institute of Science, Bangalore, under the guidance of Prof Vasant Natarajan. My Doctoral work was to study the malaria-infected red blood cells (RBC).

Current Research Interests

Using light gradient force to assemble metamaterial
Light gradient force of a standing wave optical trap can trap nanoparticle in 1D array. It can then be timeshared in an 2D lattice creating a 3D array of nanoparticles. Which then can be anchored in position by creating hydrogel scaffold around. By using step and repeat method we can create larger array, which can be used as a photonics-metamaterial.
Single Molecule Spectroscopy using nanopore
When a single denatured protein passes through a sub-nanometer diameter nanopore, added by an electric field, it changes the electrolytic current through the pore. Each nucleotide produces its characteristic current through the pore which can be read back using high bandwidth amplifier. Nanopore sequencing has the potential for very long reads, reducing the computational burden posed by alignment.
Live Cell Visualization using STEM
Visualizing some of the smallest bacteria with nanometer scale resolution while cells are still viable using low-dose STEM.

Past Research Projects

Biophysics of trypanosomes motility
Motility is an important aspect of trypanosomes' survival. I in this project we are trying to study the biophysical aspects of trypanosomes motility and how it gets affected.
Biophysical role of septins in ring formation
Role of different septin proteins in the septin ring formation during cell division.
Dissociation of biological bonds in an optical tweezers force ramp assay
Studying malaria infected red blood cells using optical tweezers
