Dr Ioannis Katis 

Dr. Ioannis Katis is currently a Research Fellow at the University of Southampton, working on laser-based manufacturing technologies for the fabrication of point-of-care medical diagnostic devices.

He has an extensive educational background that includes a bachelor’s degree in Electrical and Computer Engineering from DUTH, Greece, an MSc in Bionanotechnology and a PhD in Optoelectronics from the University of Southampton, UK.

Ioannis’ main research areas are laser-based technologies for manufacturing of paper-based diagnostic devices and lateral flow assay development. He is currently developing devices for diagnosis of Leishmaniasis and Tuberculosis and has a keen interest in bringing novel products and technologies to the market.H

He has work  experience  as a research  fellow  at  the  Lab-flo  and  RAPID-TEST  programs,  focused  on  the optimisation  of  our proprietary  laser-based  techniques  and  the  development  of  paper-based  devices for  the  diagnosis  of various diseases (Covid19, Leishmaniasis, TB, Antimicrobial Resistance).
