Dr. Dipak
Bhowmik is an Assistant Professor in the Faculty of Physical
Sciences at South Asian University, New Delhi, India. Before joining South
Asian University, he worked as a Senior Researcher at the University of
Oldenburg, Germany, in the Division of Microrobotics and Control Engineering.
His research there focused on nanoscale adhesion, friction, and interfacial
interactions, particularly the behaviour of individual nanoplastic particles
under different environmental conditions. Using atomic force microscopy (AFM),
colloidal-probe techniques, and force spectroscopy, he investigated adhesion,
friction, contact mechanics, and interfacial shear properties of micro- and
nanoscale particles and surfaces.
He received
his Ph.D. in Physical Sciences from Homi Bhabha National Institute, India, with
his doctoral research carried out at the Variable Energy Cyclotron Centre,
Kolkata. His Ph.D. research focused on surface and interface modification using
low-energy ion beams, with particular emphasis on ion-beam-induced
nanopatterning, surface chemical modification, wettability, and tailoring of
the structural and optical properties of semiconductor and functional
materials. He subsequently carried out postdoctoral research at ITER-India,
Institute for Plasma Research, and the Indian Institute of Technology Kanpur.
His current
research interests lie at the interface of ion beam physics, surface science,
nanomechanics, and atomic force microscopy. At South Asian University, his
research programme aims to develop advanced approaches for nanoscale surface
engineering, interfacial mechanics, nanomaterials, and quantum and emerging
functional materials, combining ion-beam processing with AFM-based nanoscale
characterization.
He has
extensive experience with AFM, focused ion beam, scanning electron microscopy,
electron-beam-induced deposition, ion beam systems, XPS, XRD, TEM, and related
surface characterization techniques. He has also been involved in international
collaborative research projects and research visits in Europe, Asia, and the
United States.
