Biography

Malachy obtained his BE Degree in Mechanical Engineering from The Queen University, Belfast in 1991.  He was awarded the IMechE prize for best final year project in Mechanical Engineering.   During the period 1991-95 he pursued a PhD programme under the supervision of Dr. David Artt, also at The Queens University, Belfast.  In 1996 he obtained his PhD degree with the title 'An experimental and computational investigation into flow patterns within a radial inflow turbine rotor'.  During the period, 1995-97, Malachy worked on the design of gas turbine engines at GEC Alstom, Whetstone, Leicester.  In late 1997 he returned to Ireland, working first at QUB and then later at IT Tallaght before commencing employment at UCD, Dublin in September 1998.

Malachy's main teaching interests are in fluid mechanics, currently delivering modules in stages 2, 4 and 5 of the engineering programme.  

Primarily his research interests are now in cardiovascular biomechanics with particular focus on abdominal aortic aneurysm,  cerebral aneurysm and mitral heart valves.  In 2012 Malachy was awarded the prestigious IMechE Thomas Hawley Gold Medal and the IMechE Biomedical Engineering Association Duncan Dowson Prize for his paper "An investigation of the relationship between hemodynamics and thrombus deposition within patient-specific models of abdominal aortic aneurysm.

Teaching

Teaching Philosophy

My teaching philosophy in my core subject of fluid mechanics is to deliver to the student an understanding of the basic principles and concepts involved, and through illustrative sample calculations and interactive laboratory exercises, to develop the students ability to design and solve complex engineering problems.

Enhancement of Teaching

Review and Enhancement of Curriculum

Under my coordination and direction Mechanics of Fluids has evolved to become a core subject area on both the undergraduate and postgraduate degree programmes in Mechanical Engineering. This is evident through the visibility of modules entitiled Mechanics of Fluids I, II and III in stages 2, 4 and 5 respectively. These modules develop the triumvirate methodologies of analytical theory, experimentation and computational fluid dynamics. For many years fluid mechanics was paired with either thermodynamics or heat transfer at various stages of the traditional four years BE Mechanical degree programme. Laboratory exercises in fluid mechanics were limited or almost non-existent. I had long believed that the significance of the subject within the mechanical engineering programme was obscured. Despite a number of reviews and minor changes during the early part of the last decade it was not until modularisation that I realised my objective of showing to the students a clear pathway for mechanics of fluids through the degree program. Under the current structure module content is structured as introductory, application and advanced. Each module is supported by laboratory exercises that utilise equipment long held by the university but not previously commissioned. Furthermore, the introduction of computational fluid dynamics has added a modern dimension to the syllabus. The most recent revision of the module content has come about with the commencement of the new Masters of Mechanical Engineering programme. Working with my colleague Prof. Ivankovic module content and delivery has been aligned with the two modules in continuum mechanics (Continuum Mechanics I & II) on this programme, delivering an integrated package on the continuum mechanics of both solids and fluids. Presently, programme structure and content within our school is managed by a school programme steering committee (of which I am a member).

Developing as a Teacher

Over the past 8 years I have adopted the eLearning tool Blackboard to facilitate module. I have gradually moved all of my lecture material from overhead projector to electronic presentation format. Blackboard enables me to provide for the students lecture presentation material, concise notes where required, tutorial papers and solutions, laboratory notes and assignments. It also provides a fast, easy and convenient way to communicate with the students. I continually review available texts, electronic teaching resources, laboratory methods and developments in computational fluid dynamics and techniques. I use web based sites and their associated ezines such as eFluids (www.efluids.com), CFD online (www.cfd-online.com) and CFD Review to keep abreast of recommended teaching methods and ongoing developments. In the last academic year I was a member of the staff-student committee that deals predominantly with matters relating to teaching across all stages of degree programmes within our college. Hearing at first hand some of the difficulties students have in the classroom, particularly in relation to how information is presented in complex diagrams has encouraged me to redevelop a number of presentation slides that contain some of the more detailed diagrams within my modules. This is an excellent forum.

Innovation & Leadership

My involvement in the programme development at college level has provided me with an excellent opportunity to understand the process of delivering an engineering education at both undergraduate and postgraduate level. This involvement has enabled me to provide leadership within my own school in developing our ME Mechanical Engineering programme and to innovate within my own taught modules.
