Role in the Centre

Dr Tesfamichael’s research interests are in the field of solar energy and solar cells, gas sensors and bactericidal of nanomaterials. His research is aligned along QUT’s Centre for Materials Science and is one of significance to the national and international community. His research within the Centre has been focused on development of functional materials using state-of-art magnetron sputtering and electron-beam evaporation PVD techniques. This includes nanomaterials and thin film coatings for perovskite solar cells and gas sensors. Development of thin film metal oxides as electron and/or hole transport material by the PVD systems for perovskite solar cells to enhance the efficiency and stability of the solar cells are key research topics in the Centre for Materials Science. Moreover, surface engineering of the thin film metal oxide nanomaterials for environmental monitoring and other gas sensing applications are areas of his research contribution. Dr Tesfamichael also collaborates within the Centre for Biomedical Technologies on understanding the bactericidal mechanisms of insect wings and mimicry of the nanotopography surface using advanced techniques also benefit the Centre for Materials Science. In addition, Dr Tesfamichael’s research interests include the physical, chemical, optical, electronic and electrical characterisation of nanomaterials and thin films using the cutting-edge facilities located within QUT’s Central Analytical Research Facility.

Short Biography

Tuquabo Tesfamichael received his Ph.D. in Solid State Physics from Uppsala University, Sweden in 2000. Earlier degrees include Swedish Licentiate Degree (SLD) in Materials Physics from Uppsala University (1998) and B.Sc. in Physics from University of Asmara, Eritrea (1989). He was a staff member at the University of Asmara (1990-1994); a Postdoctoral Research Fellow at Queensland University of Technology (2001-2003); and from 2003 till present serving as academic teaching and research staff at QUT. Currently he is a senior lecturer and teaches engineering materials, materials and manufacturing, strength of materials, fracture mechanics and advanced materials. Dr Tesfamichael has published over 60 referred articles in high impact and widely read journals. In addition, he has substantial citation records with Scopus citations over 1000 and an h-index of 19 underlines the strength of his research and quality of papers. Since 2001, Dr Tesfamichael has received over $2 million in research funding and awards from external competitive grants including National and International Research Alliances Program; Japanese Society for Promotion of Science Invitation Fellowship; Australian Research Council-Discovery Grant; Australian Institute of Nuclear Science and Engineering Awards. His leadership and engagement interests at QUT for the benefit of engineering profession and community are high. He has also served as HDR Deputy Director of the nanoscience Discipline, on the MMPE HDR working group, Supervisor Pedagogy Committee, Faculty Equity Committee, and most notably as a unit-coordinator for a large first-year engineering unit. Dr Tesfamichael also served on the organising committees to a number of conferences and has reviewed many journal articles and conference papers.
