Dr. Killian Walshe


Killian Walshe is a Post Doctoral Researcher in the APRG. Currently he is working in the field of microfluidics on a joint project with Cellix, however Killian still has a strong interest in fundamental research and continues collaborating with the APRG, specifically with computer simulations and Density Functional Theory (DFT). 


Upon completion of his undergraduate degree in Theoretical Physics from Trinity College Dublin in the summer of 2015, Killian joined the APRG.
Killian had previously worked with the APRG during the summer of 2014 and in the 2014/2015 academic year. 

PhD Research

Killian's PhD thesis is titled "Surface Science of Oxidised Metals: Mo,Nb & Cu". In this work the electronic and structural properties of these thin-film oxide surfaces of these metals are investigated using Scanning Tunnelling Microscope (STM)  under Ultra High Vacuum (UHV) conditions. Using STM, it is possible to image the electron density at the surface of a material, interesting features and properties are then identified and analysed before being compared to computer simulated models. Computer simulations are carried out using COMSOL Multiphysics and Density Functional Theory (DFT) simulations are performed using Quantum Espresso (PWscf).

Trinity Walton Club

Killian has been an educator for the Trinity Walton Club (TWC) from 2016-2019. The TWC is a "STEM club that sparks curiosity, fuels exploration and ignites innovation!". The role of an educator is to promote the learning of STEM subjects through problem solving, critical thinking, communication and team-work. This is achieved through weekly demonstrating sessions and mentoring groups of TWC students as they undertake projects in the field of STM. 

Other Interests:

Killian is interested in the growing field of machine learning and it's many applications.  Killian also organizes twice weekly games of soccer for Postdocs and PhD students working in Trinity.
