Dr. Kyle Anthony Baldwin is a senior lecturer in the Physics and Mathematics department, currently teaching the 1st year module Laboratory Instrumentation & Physics Skills (a practical lab-based module where students learn how to carefully perform experiments), and the 2nd year module Fundamental Forces, where students learn the principles of the 4 fundamental forces of nature: gravity, electromagnetism, and the weak and strong nuclear interactions.
In 2019-2020 Kyle will also teach the Introduction to Laboratory Software module, where students will learn the fundamentals of several programming languages, useful for running simulations and interfacing with software and hardware.
Outside of the lecture theatre, Kyle is an experimental physicist, with particular interest in fluid interactions and soft matter physics.
Kyle began his research career at NTU, achieving his doctorate studying structure formation in evaporating polymer solutions. Since then he has explored several dynamic fluid systems: the shapes of levitating, spinning droplets relevant to the geophysical phenomenon of tektite formation; the inhibition of a magnetically induced Rayleigh-Taylor instability by rotational Coriolis forces; vibration induced self-propulsion of a two-sphere dimer; switchable stable magnetic levitation stabilised by self-induced fluid pumping; and liquid crystal active emulsions, where droplets swim as the system evolves from an out-of-equilibrium state into a nanoemulsion.
Moving forward, Kyle is interested in exploring the interplay between fluid dynamics and biotic interactions. For example, the role of fluid forces in dense populations (or swarms) is poorly understood, particularly in the intermediate Reynolds number regime, where both viscous and inertial forces must be considered.
