PEOPLE
If you are interested in working with me please send me an e-mail. I have openings for various theoretical, computational and experimental projects.
Current group
Bernabe Gomez Perez, PhD student
I joined the group in September 2017. My research concerns studying propagation of sound waves in the ocean, and tracking these back to their source. I'm interested in inverse solutions of earthquakes and impacting objects, with the attempt to retrieve main properties of these sources, in particular, geometry, kinematics, time, and location of the event. I like to play guitar especially rock and Spanish music.
Favourite music: rock, jazz and flamenco; favourite song: Soothsayer by Buckethead.
Favourite movie: Delicatessen (I like French movies).
Danny Groves, PhD student
My name is Danny Groves and I am a PhD student at Cardiff University. Under the supervision of Nikos Savva and Usama Kadri I investigate into the area of droplet dynamics spreading over chemically heterogeneous substrates with mass transfer. During my undergraduate degree, I completed a third year project on investigating these phenomena in two dimensions, both numerically, and analytically using the method of matched asymptotic expansions.
My PhD is focused around extending this work into the more complicated three dimensional problem. The dynamics of the full three dimensional problem are investigated analogously to the two dimensional problem, namely, numerically using a pseudo-spectral collocation method, and analytically using matched asymptotic expansions.
Favourite music: John Williams, closely followed by Hans Zimmer.
Favourite movie: Start Wars Episode 5.
Byron Williams, PhD student
I have worked in industry for > 30 years repairing industrial lasers and study mathematics in my spare time. I am a few months away from completing an MSc with the Open University. In July 2017 I will begin part-time PhD studies under the supervision of Dr Kadri working on Tsunami detection and mitigation combining theoretical and computational aspects.
Favourite Music: Pink Floyd, Led Zeppelin, Frank Zappa, Reef
Favourite Film: Alien
Mohammed Alghazzi , PhD student
I am interested in deep ocean water transportation by acoustic-gravity waves (AGWs) originated from tectonic movements. Similarly to other well known water drifting mechanisms, AGWs may play an important role in creating currents in the ocean and transporting water that are important for the healthiness of the oceans. Although this mechanism has been demonstrated qualitatively, it is still not known how much water is being transported compared to other mechanisms. I study the distribution of the generation of AGWs by submarine earthquakes and estimate the amount of energy transferred. It is found that AGWs play a prominent role in transporting water at various locations in the ocean.
Favourite Music: Whatever my ear catches
Favourite Film: The Simpsons
Wade Parsons
I am an applied mathematician (Ph.D. in numerical analysis) with interests in a wide variety of topics such as water wave mechanics, computational hydraulics and signal processing. Recently I have been working with Dr. Usama Kadri and his collaborators on acoustic-gravity waves, especially when generated by free surface sources.
I taught engineering mathematics with the public college system in Newfoundland for 33 years (retired) and I am currently a Visiting Researcher with the Faculty of Engineering and Applied Science, Memorial University of Newfoundland.
Favourite music: Vivaldi, Bach, Debussy, Beethoven, Pachelbel, Leonard Cohen, Howard Shore
Samuel Stephens, MMath student
People around the world have been hearing peculiar low-pitched sounds which are being described as “Apocalyptic Horns” or “Sounds of the Apocalypse”. The sounds have been associated with biblical prophecies, supernatural, UFOs and other conspiracies with an unscientific explanation. However these sounds might have a scientific explanation. The sounds might be caused by low frequency sound waves, known as acoustic gravity waves (AGWs) that are generated, among others, by tectonic movements in the ocean prior to transmission through the atmosphere. I analyse the AGW frequency spectrum under different geometries and tectonic sources, focussing on the audible range.
