Programme director for BSc and MPhys Physics/ University Optical Safety Officer. 

Howard came to study his BSc in the Department of Applied Physics at Hull to pursue his interest in lasers.

After gaining a BSc in Applied Physics with Laser Technology in 1989, he was awarded a PhD scholarship by Lumonics Ltd to develop photoswitched gas lasers under the supervision of Prof Peter Dyer.

Howard gained his PhD in 1993 and was then engaged in various postdoctoral positions involving applications of lasers, particularly micromachining.

In 2001, he was appointed as lecturer to develop a taught MSc programme, Laser Applications in Micromachining and Processing (LAMP), which he successfully ran for seven years.
