Mark Tweedie joined the Nanotechnology and Intergraded Bioengineering Centre (NIBEC) at Ulster University in 2010 as a Research Associate in sensors and microfluidics and over the period has worked on various projects ranging from point-of-care diagnostic devices to the sensing of oceanic dissolved CO2 levels.
Mark studied Pure and Applied Physics at Queen’s University Belfast from 1979 to 1982 graduating with a 2.1 honours degree. He went on to complete an MSc in Optoelectronics and Optical Information Processing, graduating in 1985. From 2006 to 2010 he completed a Seagate-funded PhD at Ulster University in the area of lateral growth of carbon nanotubes. Mark has been a Chartered Physicist and Member of the Institute of Physics since 1990.
Prior to joining NIBEC, Mark was employed from 1984 to 1995 as a Technical Specialist Engineer for Sensors and Optics in the Defence System Division of Shorts-Bombardier, Belfast. During this time he investigated infrared optical detection systems, and developed optical systems for a patented indoor marksmanship simulator. From 1995 to 1998 he worked at the Microelectronics Centre at Queen’s University Belfast, fabricating specialised silicon-on-insulator substrates. From 1998 to 2003, he worked as a Research Physicist at a Northern Ireland biomedical diagnostics company on the development of a patented machine vision system for biochip quality control and a related prototype analyser for biochip assays.
