I am a Lecturer in Applied Mathematics at the University of Liverpool. I research wave propagation in complex materials and I teach Vector Calculus & Variational Calculus.

I am currently teaching two modules: Math225 (Vector Calculus) and Math430 (Variational Calculus).

Usually, the fastest way to reach me with short questions is to use twitter @danielcolquitt.

I will also offer a couple of undergraduate and MSc projects to interested students. More details can be found below.

For longer questions, please make a appointment to come and see me whenever is convenient for you.

During term-time I maintain two office hours per week where I will be available in my office for students to see me. Currently, my office hours are

Although you can drop-by without an appointment during my office hours, it is always a good idea to book an appointment to guarantee yourself a time-slot.

This course provides an introduction to vector calculus including vector differential operators, vector integrals, and the associated theorems. We will also consider some applications of vector calculus to various physical systems including fluid mechanics and electromagnetism.

In the same way that calculus is concerned with the extremisation of functions, variational calculus deals with the extremisation of functionals, or "functions of functions". Variational calculus underpins much of modern mathematical physics and applied mathematics. This module provides the fundamental background theory on variational calculus, which is accompanied by a range of physical examples.

I currently offer two undergraduate projects in Applied Mathematics, both of which are suitable for Math399, Math499, or Math490.A summary of the two projects is given below. For more information on undergraduate projects, please see this page.

The study of wave propagation in periodic media underpins cutting edge research in a wide variety of fields including photonics, phononics, plasmonics, metamaterials, geophysics, solid-state physics, and non-desructive testing.

In this project we will examine various aspects of of wave propagation in periodic media, beginning with elementary one-dimensional problems. We will introduce Bloch-Floquet theory along with the concepts of Bloch waves, reciprocal space, Brillouin zones, group and phase velocity, dispersion, band structure, and resonances.

Initially, we will consider wave propagation in infinite domains. Time permitting, we will examine more advanced problems such as transmission problems for semi-infinite domains, higher dimensional systems, and multi-phase systems.

Students may find the content of the following modules useful, but not essential: Math224, Math323, Math324, and Math427. Some experience with MATLAB would also be useful.

In this project we will study the propagation of mechanical waves in elastic solids from first principles. Elastic waves in solids posses many interesting features that are not present in electromagnetism; such waves play a pivotal role in a range of fields from non-desructive testing, to seismology, and metamaterials.

We will begin by studying waves in simple one-dimensional structures such as strings, rods, and beams. We will derive the equations of motion from first principles and introduce the necessary elementary concepts of wave propagation. We will then move on to two-dimensional problems such as membranes and shells covering infinite, semi-infinite, and finite bodies.

Finally, we will consider wave propagation in three-dimensional elastic bodies. Time permitting, problems of scattering, diffraction, reflection and transmission will be studied, as well as external loading (e.g. line and point loads on elastic half-spaces).

Students may find the content of the following modules useful: Math224, Math225, Math243, Math323, Math324, Math427.
