Early Vertebrate Development: Busy Time At A Young Age

The one-cell embryo is a deceptively simple entity during the early part of its life. From this one cell, a multicellular, three-dimensional animal eventually emerges through the process of embryogenesis. Decades of forward and reverse genetics have yielded a fairly clear view of the evolutionarily conserved molecular pathways that are essential for normal embryonic development. Yet, an unambiguous understanding of how complexity emerges in a multicellular embryo as development proceeds after fertilisation remains poorly understood.

Crystalline Arrays of Nanoparticles for Controlling Flow of Light

Advances in the synthesis of nearly monodisperse colloidal nanoparticles have made it possible
to fabricate crystalline arrays of nanoparticles (known popularly as Colloidal Nano Crystalline
Arrays (NCAs)) with lattice parameters close to the wavelength of light. Light travelling through
such crystals experiences a period variation of refractive index, analogous to periodic potential
energy of an electron in an atomic crystal. This variation in refractive index in three dimensions

Seminar on "Ultrafast Photophysics of Hybrid Lead Halide Perovskites Using Sub-10 Femtosecond Pump-Probe Spectroscopy"

Hybrid lead halide perovskites (LHPs) have been emerged as an efficient material for superior solar energy conversion during the last decade, due to their following unique properties: large absorption coefficient in the visible, low charge carrier (electron/hole) recombination rates, and sufficiently long carrier diffusion length.1-3 Understanding fundamental photophysics behind such high power conversion efficiency requires a thorough understanding of the following phenomena: dissociation excitons to free carriers, hot carriers cooling, and recombination dynamics.

Protein Post-translational Modifications (PTMs): Small Changes, Big Impact

Protein post-translational modifications (PTMs) refer to the covalent addition of functional groups onto a protein. They offer another dimension to the functional diversity of the proteins and allow them to do chemistry that is otherwise difficult. Thus, a deeper understanding on the regulatory mechanism of different PTMs can provide critical insights into various underlying cellular processes. In this talk, I will share two PTM-related stories from a chemical biology standpoint.
